Pre-Adjustment
No settings are necessary on the devices. The tripping temperature is determined solely by the response
temperature of the connected PTC thermistors.
Depending on the number of PTC thermistors the following tripping temperatures and reset temperatures
arise related to TNF (detector operating temperature):
Tripping temperature
Reset temperature
1 PTC thermistor
TNF + 15 K
TNF + 5 K
3 PTC thermistors in series
TNF + 5 K
TNF
– 5 K
6 PTC thermistors in series
TNF
TNF
– 20 K
