They also have two alarm channels. 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. The analogue output calibration is simple and sets up both current and voltage outputs. So, you can use any current or voltage output range without recalibration. 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. The Micromann can be ordered with one SPDT contact alarm instead of the standard normally open relay contacts. Alarm operation can be set to ‘manual reset’ so that active alarms will remain tripped until manually cleared.
