IntelliVAC Plus Basic Wiring 5-7
1503-UM054C-EN-P – June 2013
IntelliVAC control may be used for mechanical latch contactors.
A momentary control signal is needed to close the contactor, and a
second momentary control signal is needed to open the contactor.
The momentary open/close commands must be at least 50
milliseconds in duration.
Refer to Figure 5.6 for a typical mechanical latch control scheme.
Note:
1. A mechanical latch contactor may already be closed when power
is applied to the IntelliVAC control module.
2. It is permissible to apply an open command to the IntelliVAC
module as power is re-applied.
