Blank Display

Numbers Not Displaying Correctly (ETD System 2)

1. If the display is showing partial number, all 0's, or is frozen on a given digit, check that the safe is plugged in and getting at least 12Vac from the transformer (T-4693). If not, replace the transformer. As the batteries run down the panel may display gibberish.
2. If the power supply is good remove the display panel and check voltage into the display board:
   Red = 0 VDC
   Orange = 5 VDC ±0.2
   Brown = 5 VDC ±0.2
   Green = 0.08 VDC
   White = 3.94 VDC ±0.2
   Black = 0.1 VDC
3. If any voltages are missing replace the larger lower control board (T-9082). If these check ok start the time delay, whether by key or push button, and check the voltages again. They should be:
   Red = 4.98 VDC
   Orange = 4.96 VDC ±0.2
   Brown = 4.96 VDC ±0.2
   Green = 0.06 VDC
   White = 0.08 to 2.58 VDC
   Black = 3.5 VDC ±0.5
4. Check these voltages at H1 on the lower control board. If missing or incorrect replace T-9082. If missing at the display board replace the wire harness between these two board. If they are correct at both ends of the harness areplace the display board (T-8081).

No Response or Display, No LEDs Lit on Inner Board (ETD System 2)

1. Check that the power supply is plugged in.
2. Check for power cable damage.
3. Check that the outlet is actually powered.
4. Check that the transformer is warm. If cold, replace.
5. If in an Albertsons, check that operator is aware that the safe has a hidden display and that the key must be turned to the 10 O'clock position.
6. Check the power connection behind the front panel (particularly the red or orange wires).
7. Drill, if necessary, and open the safe to access the inner board.
8. Check for power coming into the inner board at P2. If there is no power check continuity of the power supply harness and check that the transformer (T-4693) output is no less than 12 Vac; check that the plug into the board for voltage and good solder connections.
9. Disconnect the battery back-up from P-1 and try to power it up again. If the safe powers up check the batteries and fuse. If the battery and associated fuse check ok measure the following voltages at H1 on the inner board:
   Red = 0 VDC
   Orange = 5 VDC ±0.2
   Brown = 5 VDC ±0.2
   Green = 0.08 VDC
   White = 3.94 VDC ±0.2
   Black = 0.1 VDC
10. If any of these voltages are missing or incorrect replace the inner board (T-9082).
11. Check that the wires are in proper sequence at the inner board from Pin 1 (triangle pointer): black, green, brown, white, empty, orange, red; and at the display board: black, white, green, brown, orange, red.
12. If all above check ok, replace the display board (T-8081).

No Buzzer at End of Delay

If there is no buzzer sound at the end of the delay and the door opens, check continuity of the brown wire at the back of the T-8081 display board. If the check is good replace the display board.

Solenoid Problems (System 2)

1. If the safe does not count up properly and the buzzer does not sound when the delay time is completed, replace the inner board T-9082.
2. If the safe counts up properly and the buzzer sounds when the delay time is completed check for voltage (approx 12-16 Vdc) between the two wires of the H3 connector on the inner board. Note: It may be necessary to drill the door open.
3. If there is no voltage replace the inner board.
4. Apply 12 Vdc directly to the solenoid to test it.
5. Check the solenoid wire harness continuity.
6. Check the battery for 12 Vdc.
7. If all voltage checks are good and the solenoid is ok, unplug the battery backup from the inner board and re-test. If the solenoid works now replace the battery pack.
8. When ordering parts (if available) specify door swing to ensure proper parts are sent.

Timelock Will Not Activate (System 2)

1. Probable causes include the timelock button, timelock wiring harness, or the T-9082 inner board.
2. Check if the display board shows the last timelock when the button is pressed. If not, check continuity of the timelock button and wiring harness.
3. Check whether the time shown goes up or down in 15 minute increments when the toggle switch is pushed up or down. If not, check the continuity of the switches, wire harness, and diodes in the harness.
4. Replace the inner board (T-9082).

Green Lights Flash But Time Will Not Start (System 2)

1. Check the transformer for proper output.
2. Check for proper voltages at display board harness:
   Red = 0 VDC
   Orange = 5 VDC ±0.2
   Brown = 5 VDC ±0.2
   Green = 0.08 VDC
   White = 3.94 VDC ±0.2
   Black = 0.1 VDC
3. Check continuity of wires, particularly brown and white wires.
4. If the voltages in step 2 are not present open the safe (drill if necessary) to access the inner board.
5. Check voltages at the inner board and, if cable continuity checks are good replace the inner board (T-9082). Also check the 5V regulator and other power supply voltages.
6. If all checks at the display are ok, check the keyswitch (T-4074-1) continuity. If the keyswitch and wiring check ok, replace the display board (T-8081).
