For the input, a repetition counter can be parameterized. It can be used to set the
number of errors permitted until lockout occurs. The counter also impacts the gas
shortage program (refer to chapter Repetition counter).
No. Parameter
223 Repetition limit value gas pressure switch-min
1 = No repetition
2...15 = 1...14 number of repetitions
16 = constant repetition
323 Repetition limit value gas pressure switch-min
1 = No repetition
2...15 = 1...14 number of repetitions
16 = constant repetition
Start release gas
If, at the same time, the input is used as a start release input (e.g. for an air supply
damper), it can be connected in series with the pressure switch.
When selecting Valve proving via pressure switch-min (parameter 236), function Start
release gas is not supported.
7.3.7 Oil pressure switch-min (Pmin) X9-04 (X5–01 on AGM60...)
Input for connection of a pressure switch-min for oil: If the plant does not require a
pressure switch-min, a wire link between terminal 2 and terminal 3 must be fitted.
Caution!
The OEM must check to see whether the burner can be operated without using
a pressure switch-min. This may necessitate a special approval, depending on
the application.
