Traction Auxiliary Power Supply
The MCE Traction Auxiliary Power Supply, TAPS, monitors the commercial electrical power provided to
an AC traction elevator controller. If commercial power fails, the auxiliary power supply provides single
phase backup power, directs the controller to move the car safely to a landing, and provides power to
open the elevator doors. If the elevator controller chooses a direction that draws power beyond a cus-
tomer-preset level, the system will direct the controller to pause the car, then reverse direction to the
nearest landing, again providing power to open the doors and allow passengers to exit. The TAPS unit
will then disconnect power to the elevator controller after a customer defined time period or when an
output from the controller tells it that the cycle is complete. When commercial power is restored, TAPS
will direct commercial power to the elevator controller and automatically recharge the backup batteries
for future use. Periodic maintenance and/or replacement of batteries is required depending upon fre-
quency of use and environmental conditions, but is typically in the range of three to five years. The TAPs
test switch allows you to easily test the unit periodically to see that it is functioning correctly.
