Safety Concept
The safety concept is based on the prevention of sparks and excessive temperatures by means of
various accessories.
The monitoring devices must be integrated into the system control such that operation of the
machine will be inhibited if the safety limit values are exceeded.
Temperature Monitoring
Temperature transmitter (TSA) is to detect high discharge gas temperatures.
The temperature transmitter (TSA) must be integrated into the system control such that operation of
the machine will be inhibited if the temperature exceeds the trip signal.
●
See on the nameplate (NP)
Pressure Monitoring
The pressure transmitter (PSA) is to detect high discharge pressure.
To ensure the gas tightness, the pressure transmitter (PSA) must be integrated into the system
control such that operation of the machine will be inhibited if the safety limit range is exceeded.
●
-200 … +200 hPa (mbar) (g)
The limit values of each accessory are defined in the wiring diagram chapters, see
