The input is factory configured to a specific excitation voltage and millivolt input range. The input can be configured as zero-based (i.e., 0 to 20 mV), bipolar (i.e., -30 to +30 mV) for push-pull applications, or offset (i.e., 5 to 33 mV) to electronically compensate for deadweights (tare). The alarm types are factory configured. Front-accessible potentiometers are used to adjust alarm setpoint and deadband.LoopTracker and Alarm Status LEDsAPI exclusive features include a LoopTracker LED that varies in intensity with changes in the process input signal. A two red/green bi-color alarm status LED visually indicate alarm status. These LEDs provide a quick visual picture of your process at all times.Output Test / UnlatchAPI's exclusive Output Test button can be used to verify the alarm and system operation and also provides the additional function of unlatching the alarm when the latching option has been ordered. This feature can be remotely operated. The output test button greatly aids in saving time during initial startup and/or troubleshooting.
