IntelliVAC control may be used for mechanically latched 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 3.12 for a typical mechanical latch control scheme.
Note:
1. A mechanically latched 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.
