Parameter
Description
Enable Start/Stop
function
Activate/deactivate the measuring and set the mA output to 4mA,
and set the digital relays to default.
Enable mA only function
(PLC Control)
Turn off the digital relays and also the timers. Only running with mA
output.
Defrost Start in %
Defrost start in % where the digital start relay is activated and the
mA is lock when it get to the defrost start level. E.g. 50% stops the
mA output at 12mA.
Defrost stop temp.
Defrost stop temperature when the digital stop relay is activated
and the sensor delay starts running, mA only function is 19mA.
Sensor delay in min.
(Used to ensure frost
condition before start
measuring)
Sensor delay time is used for securing frost after defrost before the
sensor start measuring again. The start and stop relay is deactivated
after timeout.
Sensor lenght in mm.
The total length of the active part of the wire between the fins (only
the wire between the fins is active).
Distance
between fins in mm.
Distance between fins in mm.
Electrical connection
CAUTION! In case of welding on the system, disconnect the power supply so that the electronics are not damaged during
welding.
