1560F and 1562F Relay Control Appendix C
Bulletin 1560F • Standard Control
The Bulletin 1560F is intended for addition to an existing motor controller,
which provides circuit isolation, motor switching, and overload and overcurrent
protection. When wired as shown in Figure 75
, the controller operates as follows:
When a start is initiated in the existing motor controller and the contactor (or
breaker) closes, a contact must be supplied to tell the 1560F to start also. Start
and Stop are the same as Bulletin 1562F • Standard Control
on page 243.
The “Fault” contact on the SMC-50 module should be wired into the existing
controller to trip the main contactor (or breaker) in the event of a fault condition
sensed by the SMC-50 module.
If possible, it is better to have the SMC-50 module control the main contactor
directly. In this case, the control circuit would look like, and function like, the
descriptions above for the Bulletin 1562F.
Bulletin 1560F • Programming Interface Control
The control scheme shown in Figure 76 allows the SMC-50 to be controlled
using Programming Interface Control. (Refer to SMC-50 Control Module—Bit
Identification on page 140 for Logic Command Word bits assignment for the
interface control). This interface includes provisions for a “Local” mode of
control as well.
With the Local-Off-Remote selector switch in the “Remote” position, start and
stop are the same as Bulletin 1562F • Programming Interface Control
on
page 244. If possible, it is better to have the SMC-50 module control the main
contactor directly. In this case, the control circuit would look like, and function
like, the descriptions above for the Bulletin 1562F.
