Details
All dimension are in inches (mm)
Main air is Port M, output is Port B, input is Port S.
Main air is Port M and output is Port B. Inputs to be averaged are applied to S1 and S2.
The output, Port B, is the lower of the two input pressures applied to Ports S1 and S2. Take
CARE when applying “one-pipe” restricted signals to S2 since the relay’s output is derived
from the air applied to S2.
No adjustments need to be made. The design allows for positive switching between signals,
and the non-transmitted signal is internally blocked. The signals applied to Ports S1 and S2
must come from “relieving” type devices. DO NOT supply from NO or NC ports of diverting
relays or solenoid air valves.
The setpoint dial can be rotated within the body to adjust the switching point. One turn yields
approximately 6 psi change in the switching point. Each unit is factory-set to switch between
18 and 23 psi, which allows it to match most two-pressure main air systems. This device is not
“snap-acting” (it must receive a positive pressure change at its signal port to switch).
