GE Industrial Solutions AF-600 FP Redundant Drive Panels - Manual (Page 13)

DEH40634 AN 11-1018 Rev.02, 09/26/2011
CTB1-1 through CTB1-3 Customer Safety Interlocks. Put normally closed contacts between CTB-1
and CTB-3. CTB-2 and CTB-3 provide an additional connection point if
required. An open circuit between these positions will cause the bypass and
drive output contactors 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.
CTB1-6 through CTB1-7
Auto Run Input. Put normally open remote run contacts between CTB-6 and
CTB-7. Closure between these positions is required for the motor to run in
either Drive-1 or Drive-2 modes when the H-O-A switch is in the “Auto”
position. The positions come jumpered together from the factory.
CTB1-19 through CTB1-21
Analog Speed Reference Input for Drive 1. Connect customer supplied 0-10
VDC or 4-20 mA “Auto” speed reference signal. This signal functions as the
drive’s speed reference when the H-O-A switch is in the “Auto” position. If
utilizing a 0-10 VDC signal, CTB1-19 and CTB1-21 are to be used. If utilizing a
4-20 mA signal, CTB1-19 and CTB1-20 are to be used. CTB1-19 is the
common terminal for either input signal. See the customer interface diagram
for details. Ground bar provided for cable shield grounding.
CTB1-16 through CTB1-18
Analog Speed Reference Input for Drive 2. Connect customer supplied 0-10
VDC or 4-20 mA “Auto” speed reference signal. This signal functions as the
drive’s speed reference when the H-O-A switch is in the “Auto” position. If
utilizing a 0-10 VDC signal, CTB1-16 and CTB1-18 are to be used. If utilizing a
4-20 mA signal, CTB1-16 and CTB1-17 are to be used. CTB1-16 is the
common terminal for either input signal. See the customer interface diagram
for details. Ground bar provided for cable shield grounding.
3. AF 600 FP Drive Terminal Board I/O
Any of the AF 600 FP terminal board I/O points which are not already in use for proper operation of the
bypass panel are available for customer use. The meanings and connection diagrams for these I/O points
are well described and illustrated in the AF 600 FP User’s Guide (DET609 – For up to 60HP@208V and up to
125HP@460/575V) which is supplied with your panel documentation package. However there are several
I/O points, which will find frequent use in bypass panel applications that they are described below for
convenience. Refer to user’s guide DET – 609 for terminal locations. Refer to section 2 and wiring diagram for
details on correct connection points
18 & 33
Need to add wire jumper in between these terminal to prevent users from
starting a drive using keypad Hand when the selector switch is in the off
position
39 & 42
4-20 mA output signal will be available from the drive at terminal 39
and 42
