Process Control setpoints 1 (PC1) and 2 (PC2) are controlled by the ionization gauge or gauges.
Setpoint 1 operates relay 1. Setpoint 2 operates relay 2. Relays 1 and 2 are also shown as K1 and K2
on the printed circuit board for reference during IG assignment. IG1, IG2, or both can be assigned
to operate either setpoint 1 or 2. Use Table 2-2 to assign the IG’s to the setpoints.
2.1.3.2 Relay Polarity Setting
The relays can be set to activate as pressure either
rises above or falls below the setpoint. A DIP switch is
provided for each setpoint. Refer to the numbers on
the switch for the setpoint number. Use Table 2-3 to
assign the relay polarity settings.
The switches are factory preset as shown on Table 2-3
for relay activation below the pressure setpoint. This is
most commonly desired when you want the relay to
be de-energized under a high pressure condition.
