Pro Mag Digital Retard Controller-Digital Controller Graphic Editor

Pro Mag Digital Retard Controller, PN 8971Digital Controller Graphic Editor, PN 7570The Pro Mag Digital Retard Controller is a programmable timing control designed for the MSDPro Mag. It can be used with single and dual Pro Mag 12 or 44 Amp systems. It is designed to beused with Pro Mag systems using a crank trigger system using non-magnetic pickups. (Thissystem will operate with the generator’s internal pickup, but is not recommended for accuratetiming.) The Digital Retard Controller has two outputs that share one common timing program.Programming the Controller can only be achieved through the Graphic Editor, PN 7570. Thissystem allows you to alter the timing with up to 30 points in 0.5° increments down to every 0.05-seconds for up to 6-seconds. This battery powered Programmer features an LCD screen thatallows you to plot a timing curve by touching the screen. This Graphic Editor can be connectedto a PC so you can save your timing curves, or download a curve that you previously downloadedto your PC. Each time the Editor is connected to the Retard Control, it goes through aseries of checks and verifications for errors and to confirm that both trigger channels are okay.Detailed instructions on the operation of the Graphic Editor and the installation of the RetardController follow. It is important to read and understand the operation of these controls prior tobeginning the installation.Parts Included with Retard Controller, PN 8971:4 - Vibration Mounts and Hardware6 - Gold Amp Terminals for Mag Pickup Trigger Cables2 - Mag Pickup/Deutsch Connector HarnessParts Included with Graphic Editor, PN 7570:1 - RS232 Harness 1 - Software CD, PN 96081 - 120 VAC/9VDC Charging AdapterNote: A heavy duty microswitch is required as a wide open throttle switch. The microswitchshould be mounted near the top of the pedal so it can react quickly. An air activatedswitch is not recommended unless it is a very fast responding design.Important: When the Digital Retard Controller is installed the timing will be 5° retarded.This is due to its improved mag pickup compensation circuit. The timingmust be checked and reset to your engine's specifications.OPERATIONThe PN 8971 Retard Controller can only be programmed with the MSD PN 7570 GraphicsEditor. All programming is accomplished through this unit’s LCD touch screen. When the Editoris turned On, all the timing data is entered by touching the LCD screen.PROGRAMMINGThe selections on the left side of the screen are the controls for creating, editing and savingyour timing curves. There are also two control buttons, Left and Right, for movement on thebottom right of the screen.

4 INSTALLATION INSTRUCTIONSTRACTION CONTROL DETECTIONThe PN 8971 has a circuit that monitors the input signals of the Pro Mag and its crank triggerpickups. If these signals are modified in any way by an external traction control device it will activatea 24 hour timer that will show on the screen and flash its Red LEDs. The LEDs and the time alertcan only be reset with a special key that the sanctioning body tech officials have. When reset withthe tech key, the reset timer will indicate Rst 24.0 Hrs on the screen. Also, power can be applied tothe PN 8971 for 24 hours continuous in order to clear the screen and stop the LEDs from flashing.The TCD event time is stored in the memory of the PN 8971 so it can be accessed by the techofficials.Note: MSD Ignition technicians cannot reset or cancel a TCD event code.MESSAGES AND WARNINGSThis system watches over itself and will display several Monitor or Warning Messages on the LCDscreen to alert you of possible problems.MessagesMessages appear on the lower left of the screen, only when the PN 7570 is connected to the PN8971 with its power On (Figure 3). It can show the following:MagDeg 0.0°MisMagA 0-255Dist or CrankMESSAGESWhen the engine is running, this shows the amount of difference betweenthe two crank trigger pickups. Channel A is always the reference pickup. Itwill show when channel B is up to +/- 9.9° in 0.1° increments from channelA.Each time a trigger signal is missed, this program will increment MisMagBor A and display it, up to 255 events. This will give you an indication that apickup connection, wiring or the pickup itself is failing. Both pickups aremonitored. This information is stored in the PN 8971 memory so it can beviewed with or without the engine running.This indicates which type of mag pickup input is being used. Either asignal from a distributor or from a crank trigger (crank is recommended).To reset the MisMag memory, the Graphic Editor must be connected to the PN 8971 and powermust be On. Press the Check button, then the Reset MagCnt.Note: The mag inputs are constantly being monitored by the PN 8971. Whenever a bad or faultytrigger signal is found, both magnetos use the remaining good pickup signal. This meansthat both magnetos will always trigger simultaneously from the most retarded pickup of thetwo input signals. Even if the pickups are slightly staggered or one pickup is lost, bothmags will be triggered together.MSD IGNITION • 1490 HENRY BRENNAN DR., EL PASO, TEXAS 79936 • (915) 857-5200 • FAX (915) 857-3344

When it is charging at a high current rate, the Charge LED on the panel will be lit. When thecharger decreases to trickle charge, the light will go out, it may require up to 5 hours after the LEDgoes out to achieve a full charge on the battery. Once it is charged, you will have 6-8 hours ofoperation (half of that when the back light is used constantly). The battery cannot be overchargedthus allowing the charger to remain plugged in after the LED goes off.When the Low Battery Alert appears on the screen, there will be about 10-20 minutes of operationleft (less than 10 with the backlight on).DIGITAL RETARD CONTROL INFORMATIONRedGreenA&BRedA&BLEDsThis single LED will alert you of a power supply problem. It will indicate that eitherthe current or voltage supply went too high or an over current condition is present.These LEDs indicate when the timer begins counting (when the full throttle switchis activated). It will blink if the WOT Switch is open (pedal lifted).These LEDs will turn on when the Control is reset and armed for the launch. It willalso flash a fault code if the Traction Control Detection determines a signal modificationhas occurred (see the TCD section), if the phasing between pickups is morethan 5° and if a trigger signal is lost.Trouble Codes: If there are multiple codes stored, they will follow one another in the sequence,then repeat. These codes are blinks on the red A or B LED.2 - This indicates that a Traction Control Detection event has been detected. For more information,see the TCD section on page 4.3 - Three blinks indicate that the trigger signal has been lost on the respective channel.4 - Four blinks indicate that there is an offset between the trigger signals that is greater than 5°.Note: The optional external Red LED has both channels tied into it. If it indicates a code 3 youwill have to see which built-in LED is flashing the code. Also, this LED will not illuminate atreset when there is a trouble code blinking on either channel.MSD IGNITION • 1490 HENRY BRENNAN DR., EL PASO, TEXAS 79936 • (915) 857-5200 • FAX (915) 857-3344
