Setting The Switching Pressure - Honeywell Fema DCM-203-574 Series Assembly And Operating Instructions Manual

1. Basic Equipment of the Pressure Switches
CAUTION: Switch off voltage.
1.4 Setting the Switching
Pressure
The switching pressure is set using the
setting spindle. Before setting loosen the
setscrew located above the scale by
approx. 2 turns and tighten it again after
setting.
The scale value corresponds to the
switching point (for rising pressure). The
reset point is lower by the switching
differential.
The scale provides only an estimated
value; a pressure gauge is required for
accurate settings.
On terminal connection housings, the
setting screw is accessible after removing
the cover.
