Door Problems

A door problem may be the result of a failed lock, failed key switch, handle, boltwork, or possibly the main board. If necessary drill and replace the lock.
1. If the display does not indicate door time when turning the DOOR key, check the key switch continuity. If the key switch is okay, check the key switch cables to the main board. If those wire check okay, replace the main module. If you experience a similar failure using the ACO key, replace the ACO key switch.
2. Handle Does Not Turn: If the normal opening procedure is used and all indications are that the door handle should turn, try using both the ACO and DOOR keys together to open the door. If that doesn't work, the problem is likely the lock. The solution is to drill and replace the lock. It is also possible that the handle or boltwork is the problem, but if the problem is not obvious, it must be assumed that the lock is at fault until the door can be opened for inspection.
3. Door Does Not Lock: If the handle may be turned to the open position at any time without using keys, check for voltage applied to the lock. If no voltage is applied the lock solenoid is failed and the lock must be replaced. Otherwise, check the key switch continuity. If the key switch checks ok replace the main board. If not, replace the key switch. Note that key switch problems are usually indicated by flashing "1000" display.
4. Display Flashes "1000" Alternating with "30": Key switch is likely at fault, otherwise possibly main board. If door cannot be opened with ACO key drill to access, then replace lock as well as key switch. Replace main board only if key switch is not the problem.

Power Problems

1. Check transformer plugged into AC.
2. Check AC outlet has power with a known working electric device such as a radio.
3. Check transformer temperature. If the transformer is cold skip to Step 8 and return only if transformer voltage check is good.
4. Check power switch.
5. On older models check the power cord is plugged into safe under control panel.
6. Replace fuse. (A blown fuse will not usually appear blown.) Fuse Spec: 4 Amp, 250V, SLOW BLOW.
7. After replacing fuse cycle power switch.
8. Check transformer output voltage. Replace transformer (T-4693) if there is no output. Unloaded, transformer output may be higher than rated loaded voltage.
9. If the safe door cannot be opened, it will be necessary to drill the safe open and replace the lock. Main (T-4529) and Display (T-4528) boards and connecting cable (T-4530) should also be available as well as a power cable (T-1036) so that the appropriate part can be replaced once the safe is opened.

Vending Problems

1. Check Display. To vend the green VEND LED must be lit. If the safe is equipped with an ON/STANDBY key switch, that switch must be in the ON position.
2. A display message of "9999" means there is a sled or plunger timeout problem. Possible faulty components are the sensor board, a motor, main board, cable, or wire harness. In many cases the problem is some sort of debris or blockage preventing sled movement. Another frequent problem is sensor board alignment. If all visual and audible indications are proper and no tube is vended, either the column was empty or a tube is stuck.
3. Check the sled cable. It should be connected at both ends of the tray, spring to the right, wound three times around the pulley, and should be snug when tugged upon.
4. Test the Sensor Board.
5. Manually force the sled fully to the left. Turn safe power off and back on. After power up the safe should move back to the home position (fully right) by itself.
6. Check the LEDs on the main board to determine if the sensors are properly indicating sled and plunger locations. Adjust sensors (i.e. adjust sensor board and interrupter strip mounting, if necessary) to obtain proper sensor data.
7. Check whether the motors attempt to move. If a motor is not responding, check to see if voltage is applied. Look for 12V at appropriate pins of J3 on the main module while attempting to vend. If voltage is applied and the motor does not attempt to move, replace the motor. If the main board does not attempt to apply voltage and indications are that it should be trying, replace the main board (T-4529).
8. If a motor does attempt to move, look for blockage again. If it is the sled, and the sled moves to a wrong column, check to make sure that the sensors are picking up each column as it passes and only as it passes across each column notch in the interrupter strip. If it is sensing correctly, the problem is the main board (T-4529). If not, adjust the sensor board or, if necessary, replace the Sensor Board.

Door Sensor Problems

The display should indicate 1000 (10 minutes) when the DOOR key is turned, then will begin to count down. If not, check the ON/STANDBY switch is in the ON position. There are no other sensors for door status.

Plunger & Sled Sensor Problems

The Sensor Board may be tested independently to verify proper operation. This is done with the safe powered up and the Sensor Board connected, but unmounted. A piece of plain paper and a mirror or shiny reflective metal surface (such as a new quarter or dime) will be needed to perform these tests.
1. The HOME sensor is SS1 on the sensor board. With an open air-gap between the teeth of SS1 the HOME light on the main board should be lit. Slip a piece of paper between the teeth of SS1 and the HOME light should go off. If the sensor does not respond replace the sensor board.
2. The COL (column) sensor is SS2 on the sensor board. With an open air-gap between the teeth of SS2 the COL light on the main board should be lit. Slip a piece of paper between the teeth of SS2 and the COL light should go off. If the sensor does not respond replace the sensor board.
3. The BACK sensor is RS2 on the sensor board. With no reflective surface near this sensor, the BACK light should be off. When a reflective surface (mirror, Aluminum foil, etc) is brought within less than a half inch the BACK light should light. If it does not, replace the sensor board.
4. The OUT sensor is RS1 on the sensor board. With no reflective surface near this sensor, the OUT light should be off. When a reflective surface (mirror, Aluminum foil, etc) is brought within less than a half inch the OUT light should light. If it does not, replace the sensor board.
