2.1.2.12 REMOTE START INPUT
The Remote Start input (terminals 35-36) is a digital input intended to provide the ability to start the
system from an external source (e.g. a switch or PLC). The remote start input is an energized-to-run
input, meaning that if the contact is de-energized the system will proceed to a WAIT state. A toggle of
the start input from the de-energized to energized position causes the system to either clear a lockout
(if one is present) or start the system (if there are no alarms). This means that if a lockout is present
and the operator wishes to start the system, two toggles of the start contact is necessary (one to clear
the lockout, and the other to start the system). This functionality is outlined in the table below.

2.1.2.13 HIGH PRESSURE INPUT
The High Pressure input (terminals 7-8) is a digital input intended to be connected to a high pressure
switch. This contact is energized to run, meaning that a non-energized contact indicates a high
pressure event. The high pressure functionality is outlined in the table below.
