AC Distribution Board

Wizzard Wiring Diagram. 

Old Style AC Board
PROBLEM INDICATORS:When the machine is turned on, none of the switches illuminate when depressed, and the machine does not function (no beep, no slew, machine appears dead).The engraving motor light is illuminated, but the engraving motor will not work, and everything else operates fine. This is also one of the symptoms for a bad power supply.The motor speed will not vary at all, or seems to vary by itself (sometimes at full speed), and everything else operates fine.The above problem indicators are not likely to be fuses, or the machine would function in some way, and the lights would not be illuminated if the fuses are burned.CHECKSCheck the connectors between the AC Distribution Board and the AC Switch Pack for a good connection, with no loose wires. Check incoming voltage to see that power is coming in. Should be 120 VAC AC distribution board - if no speed variations, update and remove C5.

NOTES:Machines shipped prior to March 15, 1985 did not have the new style AC Distribution Board. The easiest way to tell if the customer has the old or new style is whether or not there is a copper plate that covers the top of it. New style boards are the only ones with this copper plate.New Style AC Distribution Board - REV. H 80-37461. Did not have a bridge rectifier at BR1.

AC Input

On rear of Wizzard; accepts 3 prong female AC cord from you AC wall or source outlet.

AC Power/Switch Pack

This is the main power switching control panel. Includes 3 switches; power, engraving motor, and auxiliary; illuminated lights and individual fuses for each. AUX - On new model Power Paks; lighted switch. By plugging an accessory (vacuum or external monitor) in to the Auxiliary Outlet, it can be control with the Auxiliary Switch. Also has cutter RPM and engraving speed controller switches. Power is routed through this pack to the main board, engraving motor and auxiliary outlet.

PROBLEMS

The machine operates, but the power switch does not light up (usually bad light)

Switches are illuminated, but the machine dies not operate; i.e., the engraving motor button is illuminated, but the Engraving Motor does not work. Common symptom for bad power supply is similar; no power, light illuminated, and fan works.

CHECKS

Check the switch lamp if the switch does work, but does not light up.

If the switches light up but do not work, check the fuses. Even with burnt fuse, continuity check will be positive.

If continued blowing of fuses is a problem, there could be a malfunction with the engraving motor, Power Supply, wiring under the pan assembly, or AC Distribution Board.

Autolayout

Use <Shift> <Autolayout> on version 2.40 and lower, and <Autolayout> key 2.41 or higher. XL 2.41 and higher use new Autolayout and Wizzard series and XL with 2.40 or lower. New version 2.41 & above is similar to System series, while earlier versions involve manipulating the Tic Pairs.

Auxiliary Switch

See AC/Power Switch Pak

Auxiliary Outlet

The auxiliary outlet is located at the rear of the Wizzard. It can be used to plug in an external monitor, vacuum cleaner, or other accessory. The power to the accessory is control by the auxiliary switch (on power paks with lighted ON/OFF). Excessive power requirements by accessories can cause program malfunctions, or blow out the auxiliary switch fuse. Older model rocker switches activated any accessory (normally a vacuum) when motor switch turned ON. Sometimes intermittent problems are caused by static from external devices, especially vacuum cleaners. Unplug the vacuum when doing diagnostics to rule out the vacuum.

Auxiliary Table

An external engraving table (i.e. Mark XII) for the XL that connects at the RS-232 port at the back of the XL.

Auxiliary Table Switch/Port

Link from the XL to the external table. Lets the Wizzard control other engraving tables. On/OFF switch on rear of XL near the Auxiliary Table plug. If this is turned "ON’, the machines table will not respond to any commands, and screen display says "MOVING TO HOME", but isn't. Some were installed upside down.

Belt Storage Pulley

Belt rests here when changing spindles, or using diamond graver. Used to store belt while not being used. Don't turn on motor when belt is on this pulley.

Bridge

C-Table EPROM

Does calculations for the engraving program. Similar in function to a math co-processor.

Calligraphy Kit

An accessory used for engraving on metal. Includes an assortment of engraving tips which are inserted in place of your diamond tip in your diamond graver. Works best when used with calligraphic style fonts. Kit includes 4 jewelry gravers, 4 chisel gravers. Requires Diamond Kit.

Carriage Clamping Assembly

Entire Y-axis assembly which holds the clamping jig. Problems with over tightening. Removing and cleaning, adjusting spring, flipping donut.

Carriage Clamping Rod/Screw

The rod for opening and closing the clamping bars, or vise.

Carriage Following Screw

The white nylon set screw located in the middle of the cutter up/down box, and is set at the factory so that the spindle is perpendicular, or squared, to the work piece. Through wear (extremely rare), this screw can vibrate out, causing problems with engraving. It should be included in your regular maintenance procedures. Squaring The Cutter Box

Carriage Idler Pulley

Guides belt; located on the left side of the engraver, above the CRT; under the cover.

Cartridge Slots 

The two slots on the lower left side of the Wizzard for inserting external cartridges. The number one slot is the closet to the operator. Page 14, original manual for extra.

Center Support Bar

Accessory placed between the clamping bar which bridges the gap to support wider plates; keeps the plate flat.

Character Generator Chip

This processor controls the main communication between the Microprocessor and Graphics Display Controller, which communicates this information to the CRT.

Clamping Bars/Jigs

The scaled bars used to hold materials in place for engraving. They fit onto the dowel pins of the work holding vise. The four screws used to hold down the clamping bars are pan head screws with 8-32 threads, 3/8 long. (MS - machine slot for flat head screw driver). Side Stop Slide (holds plate in place on AB jig) and Knurled Head Thumbscrew 6-32 x 1/4, holds it in place.

Communications Interface chip

Information travels between the CPU-A Microprocessor and the CPU-B Microprocessor through the Data Bus. The Communications Processor is the traffic controller for the data bus, and determines who can talk and who can listen. Example: The CPU-B Microprocessor can only talk when the CPU A Microprocessor is listening.

Central Processing Unit

This is sometimes referred to as a microprocessor chip, and is the heart of computing unit of any micro computer. Also known as the STMP Chips, these EPROM's contain the system program for operating the Wizzard. They configure the CPU-A Microprocessor with what it’s function is, such as that it is to operate as a Wizzard engraving machine and not an IBM PC. This is how the CPU-A Microprocessor knows what type of duties it is to perform, and what to do with the data it receives. As the machine is going through its initialization process when first turned on, this microprocessor is getting information from the CPU-A EPROM's (STMP’s) as to what type of microprocessor it is, and what its functions are. After initialization it looks to the keyboard for signals, and stores information in the DRAM. The microprocessor works in cycles: looks to the keyboard for information; looks to EPROM's (STMP) for what to do with the information. Stores or distributes information. Then looks to the keyboard for information. Cycles are at the rate of 4 million times per second (4mhz). Information is fetched from the DRAM and sent through the Communications Processor, to the CPU-B Microprocessor, or it is to be stored, to the E2 Proms. Information also goes from here through the Communications Processor to the graphics display. Table parameters and font scaling information are computed and this information is sent to the CPU-B Microprocessor.

CPU-B EPROM's These EPROM's configure the CPU-B Microprocessor with the information as to what kind of Microprocessor it is. It gives the information required by the CPU-B Microprocessor in order to run the engraving table and sends messages to the stepper motors.

CPU B V2.20 Update

CPU B EPROM V2.20 has been updated to include two changes. The first and most obvious change is in the cutter down stroke. When pressing the cutter down key by itself, the spindle will move down the full length of travel. However, the message on the screen only appears for as long as you hold down the key. Be sure to release the cutter down by pressing the key a second time. This modification was introduced in order to make adjustment for pen kits easier since full travel is necessary. If does not affect shift/cutter down operation.

The second update is an improved CPU B internal RAM test. If there is a momentary glitch in CPU B RAM Read, the program chip will go to an internal RAM test loop several times before outputting an error code to the screen. This should cut down on the RAM error problems and verify a real error before locking up the machine.

CPU-B Microprocessor

This microprocessor works in cycles, as does the CPU-A Microprocessor. It receives messages from the CPU-A Microprocessor through the Communications Processor, and communicates to the CPU-A Microprocessor through the Communications Processor whether or not the message was received. Information is stored in the DRAM, fetched back from the DRAM at a speed it can operate, and given to the IO. Information is also received from the IO and sent to the CPU-A Microprocessor. This microprocessor is responsible for all messages concerning mechanical movement, translating engraving jobs into X, Y, and Z steps. The five command keys (START, PAUSE, CUTTER DOWN, HOME, and CANCEL) and the STOP key are read directly from the keyboard by this microprocessor.

CRT (Cathode Ray Tube)

the display screen green and amber. The CRT is used for the video display of information of the Wizzard’s engraving program. Display information is received from the graphics display controller chip. The CRT has power in excess of 5,000 volts. Do not use metal tools for making adjustments. Screen controls on right side. Page 10 Original Manual. BRIGHT and CONT knobs control the CRT. The BRIGHT know adjusts brightness on the display screen. The CONT know is for factory use only; you’ll never have to use it. What about on the XL’s.

XL CRT MODIFICATION

XL CRT modification, Will not get screen if board is updated and the CRT is not., If it has been modified the brightness control will not work.

All Audiotronics monitors must be modified if they have not yet been. This modification consists of bypassing the brightness control pot on the CPU board, by moving it to the CRT. Jumper J5, J6 and J7 behind R41 on the CRT must be cut. Then the 100K pot must be added at VR1 on the CRT. On production XL’s shipped since June of 88, the on board brightness control pot has been removed. BEWARE: If a customer does not have a 100K pot on board and you send him an unmodified CRT he/she will have no screen and no initialization. This pot must be either on the CPU board and/or the CRT.

External Monitor

It is always a good idea to have an external monitor on hand. Not only is it easier to read than the standard CRT, it is handy if your CRT goes blank. If the external monitor can still be read after the CRT goes out, you know that the CRT is bad. If the external monitor can’t be read, the problem is most likely with your main video drive chip or your video ram chips. If you have an external monitor, you can disconnect your CRT from the main board, and still operate your engraver. The CRT doesn’t have to be installed in the engraver if you have an external monitor.

Cutter Box

See Cutter Up/Down Box

Cutter Box Storage Pulley

See Belt Storage Pulley

Cutter Carriage Assembly

(Also know as the Cutter Up/Down Box) Entire X-axis assembly which holds the spindle.

Cutter Down Speed

An option in the Job Option Screen for adjusting the downward movement speed of the spindle or Carriage Assembly. Fast is the default, while slow and medium are used when rotary engraving in harder materials and with the diamond kit to avoid making small ‘dimples’ in softer materials.

Cutter RPM Switch/Knob

Controls the engraving motor speed, which determines the rotating cutter RPM’s.

Cutter Up/Down Box

Major component of x-axis (left to right) cutter carriage assembly. Holds spindle and Diamond Graver. Black Knob is a Captive Bolt 1/4 Diameter. Also called Carriage Assembly. Entire assembly which holds the spindle. The box houses the downward pressure spring. Squaring The Cutter Box. New Wizzard's have set screw in nylon adjusting screw.

Diamond Graver

Early name give to the "Diamond Kit", but actually refers to the diamond tipped tool which fits the holder.

Diamond Kit

An option for scratch, drag engraving on metal. It includes the holder (similar to a rotating spindle, but solid, and a a special diamond tipped tool called a Diamond Graver. With the Diamond Kit and Graver you can produce quality engraving on all your trophy brass and coated aluminum plates. Remember, the spindle does not rotate during scratch engraving, so the motor is not used.

Setting Up the Diamond Kit
Put the motor belt on the belt storage pulley. If the rotary spindle is mounted on the Wizzard, take the spindle off.

Remove the plastic guard from the tip of the diamond graver.

Twist the black knob on the diamond kit to make sure the tool holder is clamped in tightly.

Mount the diamond kit on the Wizzard, with the tip of the diamond graver about 1/ 2" above the clamp bar.

Compute and send the job, and press the Pause key. When the carriage stops, press  SHIFT + CUTTER DOWN, and lower the diamond or spindle to the engraving plate surface.

Engraving with the Diamond Kit
You usually need a little more down pressure when you’re scratch engraving. We’ve found that a down pressure of 2 for coated aluminum, and 3 for brass works best. Also, you’ll find there’s more "drag" when you’re scratch engraving, so the engraving speed may have to be set a little slower than you’d set it for rotary engraving.

Replacing the Diamond Graver
Diamond gravers retain their cutting edge for quite a while, but they can wear out. They’ll usually withstand several months of daily engraving before they begin to get dull. If your engraving quality looks poor, you probably need to replace the graver. Diamond inserts

To insert the new graver, loosen the set screw on the tool holder with a cutter wrench. Take the dull graver out, slip the new one in, and tighten the set screw back u p.

Donut

Early Wizzard's used a brass plate clamp donut. Although this was wonderful for never needing lubrication, it was subject to early failure due to continuous over-tightening of the clamp bars. This was upgraded in later Wizzard's and Wizzard II’s to a high tolerance stainless steel donut and threaded rod. If it is necessary to replace the donut, it is recommended that your replace the old CLAMPING ROD, or the same problem will reoccur.

Down Pressure Spring

Located in the front of The Cutter Up/down Box. Used to adjust the downward pressure of the spindle or diamond kit on the engraving surface.

Dual CPU Board

(The ‘Motherboard’) Contains the operating system, the electronics, microprocessors and software for the engraving machine. This board converts signals from the keyboard into the engraving format, and provides the drive signals to the RIFA chips, for the stepper motors to operate the engraving table.

DRAM (CPU-A)

Stores information received from the CPU-A Microprocessor so that it can be retrieved at a rate at which it can operate.

DRAM (CPU-B)

Stores information received from the CPU-B Microprocessor so that it can be retrieved at a rate at which it can operate.

E2 PROMS

See WE2

Eccentric Bar

The silver bar or rod which moves the cutter up/down (Z-axis). Eccentric Bar Tips

If your silver eccentric bar (cutter up and down) is more noisy than usual, and lubricating it doesn’t solve the problem, try this tip to reduce vibration.

On older machines, 1990 and earlier that have washers on both ends of the eccentric bar, it’s possible to loosen the allen screw on the right side of the eccentric bar. By loosening this screw, the eccentric bar can be shifted to the left. Apply a flathead screwdriver between the right side of the eccentric bar and the side of the pan assembly. Gently pry the eccentric bar to the left. Then retighten the Allen screw to hold the eccentric bar in its new location. Make sure not to rotate the eccentric bar once the Allen screw is loose. It it does, make sure when you retighten that the allen screw comes in contact with the flat portion of the stepper motor rod. Be careful not to force the eccentric bar too far to the left. This could cause the eccentric bar to jam.

Moving to far to left will cause 1-1/4 turn when you home.

Eccentric Bar Stepper Motor

The stepper motor that moves the eccentric bar (Z-axis). The x, y and z-axis stepper motors are interchangeable. The RIFA chips provide control for the stepper motors. Wizzard RIFA's Diagnostics

Engraving Motor

110 Volt AC-DC motor which provides power to the rotating cutter. Sometimes called spindle motor. Gets it’s DC power from the AC Distribution Board. Correct rotation when motor is mounted is clock-wise.

According to Dahlgren, 1/15 HP, maximum speed of the Wizzard's universal type spindle motor varies 5,000 to 8000 RPM’s. But the bearings loosen up as they wear resulting in higher RPM, providing a maximum no-load spindle sped of 10,000-16000 RPM. The bottom screw on your engraving motor (there’s two) also acts as a ground. You will notice that the area immediately around this screw is not painted. If you ever need to remove the screw, be sure and clean the surface of the pan assembly that it is mounted with steel wool or sandpaper. This is also one area to check if your machine constantly resets by itself.

Engraving/Spindle Motor

Engraving Motor Belt

Belt from engraving motor to spindle.

Engraving Speed Knob

Controls the speed of the engraving; located on the Power Pak.

EPROM

(Programmable Read Only Memory) A chip which can be programmed. The program instructions are retained even after the machine has been turned off, and can only be erased with ultra violet light. Can also accidentally be erased if exposed for long periods of time to florescent light or sunlight.

Error Messages

Prompts at the bottom of a particular layout screen indicating your have typed in an unacceptable value. Usually you’ll hear a warning beep. You must correct the error before you are allowed to leave the field. Refer to section, or see the back of the Wizzard manual.

Extend-A-Plate/Table

The Extend-A-Plate, or long plate option (XL with 2.41 or higher software) that allow engraving plates up to 12 x 48 inches. The program allows the operator to engrave upright or sideways. An Extend-A-Plate table (now standard on XL’s) allows the full benefits of the software to be utilized. An option is also available to convert your Wizzard Extend-A-Plate Subtable into a vacuum table.

Font Ports

(On Side) The left side on all Wizzard's contains a opening for 2 font cartridges which can contain up to 5 fonts each. The Wizzard will read the fonts in this order: The Fonts that are built into the engraver, Gothic, TL Roman, (plus the other 3 that are built in, if your XL is one of the early models or you have a Wizzard XL Extra) Then it reads the Fonts that are in the slot closest to the front of the Wizzard and then the Fonts located in the rear slot. If you are just using one font cartridge, put it in the slot closest to the front of the Wizzard. On the Wizzard and Wizzard 2, you can bring up a total of 8 fonts, On the Wizzard XL, you have a choice of 12 fonts.

Names of fonts on XL XTRAS; name of fonts for 5 font machines, 2 font machines, (old and newer ones).

All Wizzard's will Default (reset) back to Gothic when first turned on, when the job is saved or Wizzard is reset.

Fonts

Internal Gothic, Triple Line Roman, Utility, Three Line Helvetica, Two line Century on XL. Then Gothic and TL Roman; 1992 or so Gothic and U/L Roman. Note internal fonts of XL Xtra. Up to 12 internal fonts on line at a time - XL, Up to 8 internal fonts on line at a time - Wizzard

Function Keys

Define and refer to sections on keys

Fuse Holder

Graphics Display Controller

This translates the information received from the CPU-A Microprocessor to the CPU.

Grounding Brush

Your Wizzard has an additional brush similar to a motor brush that acts as a ground. It is located directly above the rectangle cutter up/down box, beneath the X-axis bridge. The ground brush makes contact with the surface of the X-axis. A bad grounding brush cause your Wizzard to re-initialize. However, changing this brush is quite difficult as it requires dis-assembly of the X-axis. Improper reassembly will cause an uneven X-axis. Also on Mark XII. Need to clean grease and dirt along brushes track. See Bridge.

Guillemot Key

The key to the left of the space bar is the guillemot key, or French quotation mark. It is often mistaken for a double Kern key. See Wizzard keys for additional information.

Hardware

The mechanical or moving parts of the computer/engraver.

HOME

Position A reference point from which the Wizzard moves. Usually the HOME position is approximately 4.00 inches (X-axis) across, and 0.00 inches down (Y-axis). Each machine has a unique position as the many factors that affect change vary from machine to machine.

The Wizzard then takes your X & Y positions and adds or subtracts from your center points before it does its calculations for your layout.

Setting Home On The XL

Different types available, New Hermes manual engravers jigs are usually compatible.

Job Storage Cartridge

Where Wizzard XL lets you store jobs on external job cartridges, each of which can hold up to 20 jobs or 160 lines.

Loading & Saving Jobs On The XL

Kern Keys

The Kern key is the white key located to the right of the space bar. This key can control the spacing between letters. For detailed usage, see Wizzard Keys.

Keyboard

This is a series of switches that are read by the CPU-A Microprocessor. Used as the data entry device.

Refer to section on keys

Keyboard Cover

Thin clear plastic covering used to protect the keys from dust, engraving materials, etc. Plastic chips can get between the keys, especially if your Wizzard didn’t come with a plastic keyboard cover. This can cause a lot of annoying problems. If you add one or have one on a Wizzard, still can’t engrave rotary motor. Newer ones are thinner than the originals, and seem to be more flexible. A must on earlier Genies, Wizzard's, and Wizzard II’s. Reference to section on individual keys.

Wizzard II's started to include keyboard covers as standard equipment on May, 1988. This enhancement is designed to improve the reliability of the Wizzard II. The addition of the keyboard cover does not mean that a customer can engrave in metals without invalidating their warranty.

Kosher Klamp

See Versa Klamp.

Leadscrew

Threaded rod attached to the stepper motor which moves a carriage assembly (X-axis leadscrew controls the Cutter Assembly and Y-axis controls the movement of the Clamping Assembly Carriage.

Leadscrew Coupling

Early Wizzard's used a crimp-on nylon coupler between the motor and the leadscrew. Later models used a sold metal coupler with four cup-point Allen head screws. The nylon couplers should be replaced with the solid metal coupler, and Allen screws tightened  with a torque wrench, to at least 35 ft. pounds to prevent slippage. In newer machines, these screws will occasionally work loose, causing poor engraving quality. They must then be retightened to the original specs. New models use 8 screws.

Leadscrew Nuts

Connects the respective carriage assembly to the leadscrews.

Limit Switches

These are normally closed switches, and open only when the cutter or carriage truck physically run into them and open the circuit. When a limit switch fails it is usually in the open position. This causes the machine to read that the cutter or carriage truck has reached the limits in the direction it was traveling, and it will rest, or reverse direction. If the limit switch is defective and opens, the machine becomes confused, and thinks it has already read the limit, and sometimes ill think it has reached a second limit, and will become very erratic in operation, or may not operate at all.

These switches are physically operated by table and carriage contact. Signals are read by the CPU-B Microprocessor through the IO.

ON/OFF Switches

Recently my on/off button on my Wizzard didn't work (old, flat rocker style). Until I could get it repaired, my computer friend came up with a quick fix.

There are two wires, one black and one yellow that are on the bottom side of the switch. To bypass the bad switch, he cut one of the wires that was soldered to the switch, and resoldered it with the other wire. I used a power strip as an on/off switch until the switch could be replaced.

Pan

Protects inner workings from the outside

Pan Assembly

The mechanical table portion of the Wizzard. Comprised of three stepper motors (X,Y, and Z axis), Limit Switches, Cutter Truck, Clamp Truck, Leadscrews, Leadscrew Nuts, Clamp Vice, and Plate Clamp/quick Release Mechanism.

This is the mechanical table portion of the Wizzard. It comprises 3 stepper motors (for the X, Y, and Z axis), limit switches, cutter truck, clamp truck, leadscrews, leadscrew nuts, clamp vice, and plate clamp/quick release mechanism (donut).

Problem Indicators And Checks:
Poor letter quality, flattened letters, wandering baseline, etc.

This is usually caused by a mechanical problem with either the X, Y, or both couplings. If the couplings have loosened, the motor may step, but the couplings will allow slippage, so the carriage or table will not move according to the motor steps.

Another cause may be a bad Stepper Motor (rare), weak RIFA Chips (infrequent), or bad STMP Chips (very rare).

The machine continuously tries to go home (grinds at the upper left hand corner), moves to the lower right hand corner of the machine instead of going home, or the eccentric bar continues to go up and down under the slew test.

The problems are all associated with limit switch problems.

Clamp nut slipping, engraving plate vice slips, plate will not stay tightened, etc. are all caused by a faulty plate clamping mechanism.

The plate clamp donut is stripped, or the threaded plate clamp rod is worn.

The baseline wanders or is off in accordance with the measurements taken from the top of the plate. Bad ghosting of letters.

This is usually caused by the cutter not being square with the material (operator error).

Check for a loose eccentric bar - tighten the set screw.

Check the cutter carriage following screw for adjustment.

NOTES:
In general, relatively few things go wrong with the electronic portion of the pan assembly. Most of the symptoms listed are associated with mechanical problems, although in some cases they may also be created by an electronic problem.

Quick Release Mechanism

Early Wizzard's used a brass plate clamp donut. Although this was wonderful for never needing lubrication, it was subject to early failure due to continuous over-tightening of the clamp bars. This has been upgraded in later Wizzard's and Wizzard II’s to a high tolerance stainless steel donut and threaded rod. If it is necessary to replace the donut, it is essential that you also replace the donut, it is essential that you also replace the rod, and the new donut will wear out the old rod, and the same problem will recur. See Work Holding Vise for Diagram.

RIFA Chips

The chips which receive information from the IO Buffer, and translate low current microprocessor signals into high power motor signals. These signals turn the power to the X,Y and Z stepper motors off and on. They can overload the whole system causing the screen to go blank.

Wizzard RIFA's Diagnostics

Slew Test

Process of testing the X,Y, and Z axis of the machine. The spindle will move diagonally to the bottom right had corner, the spindle will go up and down, and the spindle will return diagonally to the upper left hand corner. This test is very useful in diagnosing mechanical failures.

Slew Procedure

• Turn the machine off
• Simultaneously hold down all 5 of the light blue keys in the upper left hand corner of the keyboard (START, PAUSE, CUTTER DOWN, HOME, CANCEL).
• While holding down the 5 light blue keys, turn the machine back on. Continue to hold the 5 light blue keys down for approximately 5 seconds after turning on the machine.
• The machine should begin to slew continuously until the STOP KEY is pushed.
