Figure 5-12. Wiring Diagram—Time Delay Override, Option DD-08-D
Troubleshooting The Bypass
Emergency-To-Normal Time Delay
Pushbutton
This section covers the steps to take to verify that
pressing the Bypass Emergency-To-Normal TimeDelay
pushbutton will override the emergency-to-normal time
delay.
First ensure through the software that a 10 second
emergency-to-normal time delay is set. While the
emergency source is being used, initiate an
emergency-to-normaltimedelaybyrestoringthenormal
source. Then press the Bypass Emergency-to-Normal
Time Delay pushbutton.
If afterpressing the Bypass Emergency-to-NormalTime
Delaypushbuttontheemergency-to-normaltimedelayis
not bypassed, connect TB-DC1-4 to TB-DC1-34.
1. If grounding TB-DC1-4 causes the emergency-to-
normal time delay to be bypassed but the Bypass
Emergency-to-Normal Time Delay pushbutton is
not operating, check the Bypass Emergency-
To-NormalTime Delaypushbutton andthe wiringto
the Bypass Emergency-To-Normal Time Delay
pushbutton.
2. If after grounding TB-DC1-4 the emergency-to-
normal time delay is not bypassed, check the
continuity between P2-4 and TB-DC1-4.
a. Remove power from the logic board.
b. Disconnect the P2 ribbon cable connector from
the power supply board.
c. Using an ohmmeter, connect one test lead to
P2-4 on the power supply board. Connect the
other test lead to TB-DC1-4. If there is an open
circuit, replace the power supply board. If the
resistance is low, the main logic board is bad.
Replace the logic board assembly.
