1.5.2 Selecting a Sensor
Digital inputs 1-4 are used to select which connected sensor on the network is configured.
Sensors are selected using their RS485 node address (1-16).
Binary 0000 is used to select sensor address 1.
Binary 1111 is used to select sensor address 16.
1.5.3 Selecting a Calibration
To select a calibration, inputs 8-16 are used. Any calibration in the ‘Available Calibration’ list
for the selected sensor can be selected. Each calibration is allocated a unique number when
created. Any calibration number up to 255 can be selected.
1.5.4 Trigger the Calibration Change
To trigger a calibration change, digital input 0 must be set to high. The change is triggered
on the rising edge of the trigger bit.
1.6
Alarm
The unit has a 24v DC alarm output that is configured to trigger when the electronics
temperature reaches 80
°
C. If this alarm is triggered, forced cooling will be required or the unit
will automatically reduce its performance to protect the electronics. It is essential that the
temperature is maintained below 80 ° C to ensure the electronics are not damaged. The output
is a voltage free contact and must have a load connected.
