8.2 Troubleshooting on the HTFr after a safe state has been triggered
NOTICE
N7.0000
Overheating of the HTFr
Using the wrong switch setting for cooling down
−
If the switch on the HTFr is set to position 0 before the furnace has cooled
down sufficiently, this may result in overheating and the triggering of a
safe state. The cooling cannot take place on setting 0 because the HTFr
is without power on setting 0, and the fan is therefore also turned off. The
HTFr must be set to level 1 to cool down.
•
Set the HTFr to position 1 to cool down.
•
Only set the HTFr to position 1 once the machine has cooled down
sufficiently.
After the safety circuit (see
”) has triggered, heating of the HTFr is not permitted
and is interrupted.
If the HTFr has been put into a safe state, both LEDs (
1
) on the front of the HTFr flash:

Proceed as follows to check the fault after the safety circuit on the HTFr has triggered:
1. In the ELEMENTS software, establish which fault has caused the safety circuit to trigger.
2. If the fault is the triggering of the temperature switch, turn the HTFr switch to Position 1 and
allow it to cool down until the LEDs stop flashing.
