Lim
Operating parameter (HSS sends output signal, which operating
parameter, Lim1 or/and Lim2, has or have been reached or
exceeded)
MB
Measuring range (HSS sends output signal, which of the measuring

Status signal (RS1)
The alarm output is a collective alarm with various single alarms connected in
series. The collective alarm RS1 is in the GO-state and the relay contact is closed,
when all single alarm signals are in the GO-state (Safety first).
The collective alarm includes the following single alarm messages:
Sensor temperatur is higher or lower than stated in the specifications: 55 °C
±
3 °C (131 °F
±
5.4 °F) or during warmup
P_IN (incomming pressure) is higher or lower than 600-1600 mbar or the
pressure difference between P_IN and P_OUT is too low
Gas flow is higher or lower than 25-120 l/h, it is possible to deactivate this alarm
message (using a parameter)
Power outage (Power OFF/Fail)
The gas connection diagram uses the following definitions:
