Delay in sensor activation
1) Can be caused by a gas pocket
that displaces the liquid.
2) The sensor is sealed with (too
much) Teflon tape so that there
is no metallic contact between
the sensor mechanism and the
vessel.
1) Install the sensor so that the
gas pockets cannot displace the
liquid
2) Make sure that the sensor has
a metallic connection to the
container.
Output and 4xLED are
constantly activated, even
though liquid is not in contact
with the sensor.
Threaded sleeves are installed
with a negative slope so that
liquid can collect in the threaded
sleeves, which activates the
sensor.
Place the threaded sleeves
according to the instructions. See
installation.
Function of charge output on pin 3 & 4:
NC:
There should be no signal when it is in refrigerant.
NO:
There should be a signal when it is in refrigerant.
Sensor repair
The sensor electronics are completely sealed and can therefore not be repaired.
In case of faults with the sensor, it will typically only be necessary to replace the electronics.
Complaint cases are handled by the HB Products dealers/distributors.
Their complaints procedures must be followed before returning the sensor.
