TAPS Operation Review

Commercial Power Present

• TAPS backup power source charges automatically
• TDJ relay picks, enabling

KMO

contactor to pick and opening the feed to the P1 input on

the TAPS-VF board

•

KMO

contactor picks, shunting power directly to the controller and disabling the

KM5

contactor (

KMO

interlocked with

KM5

)

• Indicator NORMAL POWER lights green

Commercial Power Lost

• TDJ relay drops, disabling

KMO

contactor and closing feed to the P1 input on the TAPS-VF

board

• UPS supplies single phase AC output to power transformer T1,

KM5

contactor picks, pro-

viding backup power to control

• Indicator BACKUP POWER lights amber

Note

Elevator safety string remains functional when backup power is provided so that no electrical
protective devices are rendered ineffective.

Main Line Disconnect Open
This disconnect is a contact between terminals BS1 and BS2.

Please refer to “Control Wires BS1

and BS2” on page 12

• 24V+ signal to TAPS-VF board removed via an auxiliary contact on the disconnect switch

(pole 4), ensuring that the

KMO

and

KM5

contactors will not pick.
