Configuration Tool Settings
1. Enter Phone Numbers and Unit ID in the General Settings tab.
2. Set I/O3 as Analogue, and tick the phone numbers that are valid for this alarm. In this case
4mA represents -40 °C which corresponds to 500mV and 20mA represents 85 °C which
corresponds to 2500mV. Therefore the 1500mV trip point equates to 22.5 °C, in the example
below a restore message will be sent when the temperature drops back below 22.5 °C.
Note: contact ETM for more information on how to correctly set and calibrate analogue
inputs.
Hysteresis can be set; this is useful in eliminating nuisance alarms resulting from
analogue values fluctuating above and below the alarm setpoint causing multiple alarms
to be sent. In this example 25mV hysteresis equates to approx. 1.5 degrees.
