C6097A,B PRESSURE SWITCHES
65-0237—1 6
OPERATION AND CHECKOUT
Operation
The manual reset C6097A diaphragm actuates the snap-
acting switch to break a control circuit and lock out when
pressure falls to the scale setting. The recycle C6097A
models recycle automatically when the control circuit returns
to scale setting plus differential.
The manual reset C6097B diaphragm actuates the snap-
acting switch that breaks a control circuit and locks out when
the pressure rises to the scale setting. The recycle C6097B
models recycle automatically when the control pressure falls
to the scale setting minus differential.
Manual Resetting
The C6097A manual reset models lock out when pressure
falls to the scale setting and require manual resetting after the
pressure rises to scale setting plus differential to resume
normal operation.
The C6097B manual reset models lock out when pressure
rises to the scale setting and require manual resetting after
the pressure falls to scale setting minus the differential to
resume normal operation.
To reset, once normal operating pressure is restored, push the
reset button in as far as it goes, then release.
IMPORTANT
Lockout models cannot be made to recycle
automatically by permanently holding in the reset
lever.
