Appendix 4 / Inhibit Input
The INHIBIT input allows the actuator to be turned off (inhibited) by a customer-supplied control
signal.
There are four customer-selectable INHIBIT operating modes. These modes are controlled by
parameter 19. Refer to page 17 for more information about setting controller parameters.
The INHIBIT input requires an isolated contact closure. To activate or deactivate the INHIBIT
input, close (short) or open the connection between J7 terminals 8 and 9 (refer to the diagram
below).
Note:
The INHIBIT input will override all Discrete Isolated inputs. To allow the Discrete Isolated
inputs to operate properly, the INHIBIT input must be inactive.
Note:
The INHIBIT input is
not
opto-isolated. If your application requires an
opto-isolated
INHIBIT input, then set parameter 72 to 1. Refer to page 17 for more information about setting
controller parameters.
Electrical Specifications:
Non-isolated contact-closure input
Description
This input must be connected to an
isolated contact or a sink-connected
