Customer Terminal Board - GE AF-600 FP User Manual

2. Customer Terminal Board – "CTB"
The following section does not apply to the Disconnect Drive Panels. All customer terminations for control
wiring are made on the drive's connections. Refer to product user guide for details.
Inside the panel enclosure there is a terminal board for convenient connection of customer control wiring. The
customer interface drawing provides a visual reference of the terminal board positions with the detailed
descriptions as follows:
CTB1-1 through CBT1-3
CTB1-4 through CTB1-5
CTB1-6 through CTB1-7
CTB1-10 through CTB1-12
CTB1-13 through CTB1-15
CTB1-14 through CTB1-15

Customer safety interlocks. Put normally closed contacts between CTB1-1 and
CTB1-3. CTB1-2 and CTB1-3 provide an additional connection point if required.
An open circuit between these positions will cause the drive output to stop
and/or drive output contactor to drop out resulting in power being removed
from the motor. These positions come jumpered together from the factory and
require removal of the factory jumpers prior to connecting customer normally
closed contacts.

Provides customer with "drive ready to run" status via contact closure. Panel
conditions that provide contact closure are; 1) drive output contactor is
energized with drive not faulted and 2) drive has been issued a run command.
Typical use for this status is "drive enabled" ready for speed reference to output
power to the motor. Contacts are rated 5A @ 240V AC, 24 VDC.
Put normally open remote run contacts between CTB-6 and CTB-7. Closure
between these positions is required for the motor to run when the
Hand/Off/Auto switch is in the "Auto" position. The positions come jumpered
together from the factory.
Provides customer with a drive fault status via contact closure. Contacts are
rated 5A @ 240V AC, 24 VDC.
Provides customer with a drive running status via contact closure. Contacts are

Place normally open contacts between CTB-14 and CTB-15. Closure between
these contacts cause the motor to run at a preset speed (speed programmed
by function code C20) from the drive. A typical use for this input is a smoke
purge command.
