Auditor Autobank - Driver Board

Driver Board Replacement

Physical replacement of the Driver boards is relatively straightforward. Ensure power to the safe is off while changing circuit boards. Use special care to ensure cables taken from the old board(s) goes on the new board at the same connector and with the same orientation. Always use static protection.
1. If possible, run the following reports: 107, 108, 110, 111. These reports should be run immediately prior to commencing service because CPU/Driver replacement also replaces the log.
2. Unload all columns.
3. Observe Normal Power-Up: After replacing the board(s) power up the safe. Note the front panel displays the messages ROM STARTUP V2.0, CHECKING FLASH CODE, and then AUDITOR V5.5 (or applicable version number). After several seconds it will display the date and time. After several seconds it normally flashes an LC:FAIL message very briefly, then returns to the date and time. Before pressing any buttons on the keypad please wait for this message to flash by.
4. Perform 97 Reset.
5. Program and enroll users.
6. Adjust the output sensor trim for 1/2 travel. To do this, locate R7 on the Driver Board. It is a blue trim pot located near the DROP LED. Rotate R7 clockwise until you feel it begin to click. Rotate R7 counter-clockwise 25 full turns. The DROP light should be lit.
7. Test safe operation.

Driver Board Voltage Checks

JP1: Key, Lock, and Door Sensor Connections
JP1 Pin 1: Ground.
JP1 Pin 2: Door 1 Sensor. 0V when the door is closed (closed circuit through lock and external door sensors), 5 Vdc when either the lock or external door sensor senses a door open (open circuit) condition.
JP1 Pin 3: On/Standby Switch. 0V when on, or if no On/Standby switch exists on safe. 5V if On/Standby switch is set to off.
JP1 Pin 4: Ground.
JP1 Pin 5: Key Detect. 8V static, 0V when the door key is turned, 16V when the ACO key is turned.
JP1 Pin 6: Unlock (lock control voltage). 16V static, 7V when opened under cpu control (ie. opened by normal procedure using either key), or 0V when using the dual key override.
JP1 Pin 7: 16Vdc.
JP2: AC Inlet
JP2 Pin 1: 16 Vdc (blue wire to power supply board).
JP2 Pin 2: Unused.
JP2 Pin 3: 5 Vdc (red wire to power supply board).
JP2 Pin 4: Ground (black wire to power supply board).
J2: Coin Cell
J2 Top: Ground.
J2 Bottom: 5Vdc.
JP3: Motor Control
JP3 Pin 1 to 2: Sled Motor. 12Vdc when energized, polarity depends on motor direction.
JP3 Pin 3 to 4: Plunger Motor. 12Vdc when energized, polarity depends on motor direction.
JP4: Sensor Board Connector
There are no voltage measurements to take at JP4 directly. Refer to the Sensor Board voltage check section below or to the Sensor Board test procedures.
JP6: AC Inlet
JP6 Pin 1: 14 Vac re: Pin 2.
JP6 Pin 2: 14 Vac re: Pin 1
JP10: Duress Signal
JP10 Pin N/O: Relay connection when duress is activated.
JP10 Pin N/C: Open circuit when duress is activated.
JP10 Pin COM: Common circuit connection for duress signal.
JP11: Output Sensor
JP11 Pin 1: Emitter Low. 3.5 Vdc (varies with R7 adjustment).
JP11 Pin 2: Emitter High. 5 Vdc.
JP11 Pin 3: Sensor Common. 5 Vdc.
JP11 Pin 4: Drop Detect. 4.75 Vdc when the Drop LED is on (beam made) or 0V when the Drop LED is off (beam broken).
