Interlock Relay Feature

As the name implies, the interlock relay feature reassigns one, or more,
alarm/control relays for use as interlock relay(s). An Interlock contact is wired to
the digital input and triggers the interlock relay. This feature is enabled by
configuring the relay and digital input (see page 70).
In one example, a dry interlock contacts are connected in series to the F4 digital
input which will be used to force on (energize) the assigned interlock power relay
when all interlock contacts are closed (safe). The interlock relay front panel LED
flashes when locked out. The interlock relay would be wired in-series with the
load (N/O contact). See below.
