9. Connect the:
a. Trip leads across the terminals of the manual Trip switch on
the circuit breaker control panel.
b. Close leads across the terminals of the manual Close switch
on the circuit breaker control panel (local connection
schemes may vary).
If the manual trip switch connections are inaccessible:
• connect between the +DC voltage supply of the terminal strip
to the input side of the trip coil.
This configuration also serves for close coil operations.
Either method, across the switch or using the coils makes
the TDR9000 a series switch that applies +DC voltage to the
appropriate coil for operation.
10. Taking appropriate safety precautions, use the attachment accessories
provided to connect an:
• OCB Contact Monitor cable to the OCB connector on the
TDR9000 OCB/Motion module and then to the appropriate
circuit breaker bushings.
See A in Figure 4.13 on page 4-30. Connect alligator clip leads as
labeled, A,B,C Common or 1,2,3 Common.
or
• EHV Contact Monitor cables to the EHV connectors on the
TDR9000 EHV module and then to the appropriate circuit
breaker bushings.
See C in Figure 4.13 on page 4-30. Connect alligator clip leads as
labeled PH A, Contact 1,2, Common, etc.
Analog and
Auxiliary Setup
Setup issues for the Event module include:
• Monitoring Auxiliary Channels
• Monitoring Analog Channels: Current and Voltage
Monitoring
Auxiliary
Channels
The TDR9000 Auxiliary Contact channels support inputs from external
devices. Auxiliary Contacts can be wetted with voltages from 48 to 300 V
peak. Configuration is performed using the Auxiliary Contact Connector
or the Auxiliary Contacts dialog box of the Virtual Front Panel. Refer to
”Configuring the Event Module” on page 4-51.
