ADJUSTMENTS
The two thumb adjustment dials, accessible
through the enclosure cover, are used to
adjust the set point and reset point of the
switch. The dial scales and pointer may be
used to give an indication of the low and high
set points.
The high setting adjustment dial is calibrated
for increasing pressure. The low setting ad-
justment dial is calibrated for decreasing pres-
sure. For best accuracy, make the final ad-
justments with a pressure gauge at the actual
working media pressure and temperature en-
countered in the application.
The minimum deadband (minimum span be-
tween set and reset points) may be obtained
at any point in the operating range of the
switch.
When the desired settings are obtained, re-
place the adjustment cover. The adjustment
cover and enclosure cover can be made
tamper resistant by a single sealing wire
inserted through the hole in the locking bar.
The repeatability of the set and reset points is
typically ±1% of the operating range.
