TAPS, Traction Auxiliary Power Supply
Functional Test
Mainline Disconnect Verification:
This verifies that the fourth pole of the main line disconnect or micro switch is functional when
power is intentionally shut off at the main line disconnect.
1. Verify that BS1 and BS2 are connected to the fourth pole of the main line disconnect.
2. Set the AC/TAPS DISCONNECT switch to the ON position.
3. Shut off power at the main line disconnect.
4. Verify that the car is not energized and remains stopped.
TAPS and Controller Operation Verification:
1. Ensure the main line disconnect is in the ON position.
2. Ensure the AC/TAPS DISCONNECT switch is in the ON position.
3. Ensure the TAPS BYPASS switch is in the NORMAL position.
4. Verify the NORMAL POWER indicator is on.
5. With empty car, move the elevator on inspection slightly above the leveling zone of the
floor with the longest floor distance moving in the up direction.
6. Push and hold the test button until TAPS is in backup power mode. Verify the BACKUP
POWER indicator is on.
7. Quickly put the elevator back to normal operation.
8. The elevator should begin to move in the up direction until it reaches the floor above.
Once the elevator reaches the floor, it shall cycle the door.
9. If TAPS shuts down before the elevator completes the rescue operation due to the timer
set in parameter F1-1 “Backup Power Run Time,” extend the timer accordingly and per-
form the test again.
10. If TAPS shuts down before the elevator completes the rescue operation due to battery
voltage drop below F1-5 (error code E-04), let the TAPS charge for 8 hours before per-
forming this test again.
11. If input P3 “Rescue Operation Complete” is used, TAPS shall shut down once the rescue
operation is complete and input P3 is energized. This will immediately cancel the
parameter F1-1 “Backup Power Run Time.” If the command is not issued to the TAPS
unit, please check wiring and controller output.
12. If input P2 “Restart Backup Power Operation” is used, verify by pushing the DOB button
in the COP to validate proper wiring and operation. This can be done once TAPS has
been shut down by either P3 input or parameter F1-1 “Backup Run Time” having
elapsed. TAPS shall then restart when the DOB is pressed and will operate until either
P3 is activated or parameter F1-1 has expired.
13. If input P1 “Remote Backup Power Operation” is used, verify correct operation by trig-
gering this input from the appropriate controller output or the source it is wired to. To
do this, TAPS shall be on commercial power operation and “Normal Power” indicator
shall be lighted. When the P1 input is triggered and held for the duration defined by F1-
9 “Commercial Power Loss Detection” (factory default is 2 seconds), TAPS shall proceed
to “BACK UP” power operation and indicator BACKUP POWER shall light. TAPS shall
then operate until cancelled by either input P3 “Rescue operation Complete” or by
parameter F1-1 “Backup Power Run Time” having elapsed. Note that shut down may
also be caused by drained/discharged batteries, dead batteries, or an inoperative UPS
unit.
