14.3.2 Error Heating
The error is raised if there is not enough heating power available and the heating current (internally measured)
falls below the threshold of 5.1 A.
Possible cause: Troubleshoot:
Cable too long The heating works nevertheless, but does not work with the full power.
Replace the cable with a larger wire cross-section or multiple wires.
Cable cross section too small The heating works nevertheless, but does not work with the full power.
Replace the cable with a larger wire cross-section or multiple wires.
Power supply defective Replace the power supply.
Heating cable defective or not
connected
Replace the defective cable or connect the cable according to the connection
diagram.
Internal heating connector
(above) not plugged in
Then the error flag “Fault temperature sensor above” is also set. Plug the
heating connector to the heating board.
Heating element defective Check the resistance of the heating elements on the terminals. If this is
high-impedance, replace the heating element. In order to determine whether the
heating element is defective, you can also set in the laboratory the maximum
heating temperature and the target temperatures (above and below) to 10 °C
above the ambient temperature and feel which heating does not heat up.
After troubleshooting, please restart the
rain[e]H3
.
14.3.3 Error Temperature Sensor Below
The error is raised when the lower temperature sensor no longer supplies data for monitoring the heating.
Possible cause: Troubleshoot:
Internal heating connector
(small plug at the bottom) not
plugged in
Check the plug and, if necessary, plug it into the heating board.
The temperature sensor below
is defective
The temperature sensor below does not provide any data. The temperature
sensor must be exchanged together with the weighing unit.
After troubleshooting, please restart the rain[e]H3 .
14.3.4 Error Temperature Sensor Above
The error is raised when the upper temperature sensor no longer supplies data for monitoring the heating.
Possible cause: Troubleshoot:
Internal heating connector (top)
not plugged in
Then the error flag “Fault heating“ is also set. Plug the heating connector to
the heating board.
The upper temperature sensor
is defective
The temperature sensor above does not provide any data. The temperature
sensor must be exchanged together with the upper housing (including ring
and funnel heating).
After troubleshooting, please restart the rain[e]H3 .
