Operation
The 3101 High/Low Limit Controller provides con-
trol output and visual indication when the process
variable exceeds the limit setpoint. The control-
ler can be setup to operate as a high or low limit
controller at the “controller type” menu:
On Powerup:
The controller status on powerup depends on
the process variable. If the process value (PV) is
within the setpoint range (i.e. below setpoint for
high limit, above setpoint for low limit), the con-
troller will begin normal operation. If the PV is out
of the setpoint range (above setpoint for high limit,
below setpoint for low limit), the controller will be
in the limit alarm condition and cannot be reset
until the PV is within the setpoint range or the
setpoint is adjusted (above or below the PV).
To reset the limit output for normal operation,
press
RESET
. This will put the output relay in the
energized, normal operating condition. If the
process variable is above (or below) setpoint, the
controller will remain in the alarm condition and
the limit output cannot be reset.
