Universal Alarm Modules
Description
The Micromann series are fully isolated,
microprocessor based, alarm modules
for use with most common process
measurement signals and sensors.
You can program all features of Micromann
operation through the front panel keypad.
When the set-up is complete, you simply
remove the security link to protect the
setup.
You can tailor each alarm’s operation
individually during setup. If necessary, you
can also allow setpoint adjustment (from the
front panel) during normal operation.
Alarm operation can be set to ‘manual reset’
so that active alarms will remain tripped until
manually cleared.
