Thermal cut-out

Thermal cut-out (hereinafter — unit) connected to a sensor located
in the heating elements area. Outupt of the limiter runs the
contactor that feeds the heaters. In case of high rise of the
temperature in the heaters area the module opens the contactor,
thus de-energizing the heaters.
While in operation, the display reads temperature on heating
elements and the unit is in operational mode.
There are two setting groups — Group 1 and Group 2. To enter Group 2, press and hold
for 4 seconds; release once display reads PAr2.
To enter Group 1, press and hold
Press to list parameters. Press
to change the value. Press
When nothing pressed during 30 seconds, the unit returns back to operational mode. To
return back to operational mode earlier, press and hold
To change set value (SV) use
It is a must to change parameters in the same order as they appear in the chart, except
parameter LoC. It must be set to oFF to unlock other parameters. Once all parameters are set
up, change the value of parameter LoC in accordance with the chart.
After changing parameters In-t (sensor type), UnIt (measurement units), parameters H-Su, L-
Su, AL1, AL2, AHYS are initialized and must be set again. The unit has more parameters than
listed in the chart. Skip a parameter if it is not in the chart. Parameters might be locked
(depending on current value of parameter LoC). Before setting up parameters, set parameter
LoC to 'oFF'.
