Valve proving
0
Fuel valve 1 (V1) leaking (fuel valve 2 with valve proving via X5-01)
For valve proving via X5-01 (gas pressure switch-min) - Check to see if the valve on the burner side is leaking - Check to see if the pressure switch for the valve proving is closed
when gas
pressure is present - Check wiring to see if there is a short-circuit
1
Fuel valve 2 (V2) leaking (fuel valve 1 with valve proving via X5-01)
For valve proving via X5-01 (gas pressure switch-min) - Check to see if the valve on the gas side is leaking - Check wiring to see if there is a short-circuit
2
Valve proving not possible
Valve proving activated, but pressure switch-min selected as input
function for
X9-04 (check parameters 238 and 241)
3
Valve proving not possible
Valve proving activated, but no input assigned (check parameter
s 236 and 237)
4
Valve proving not possible
Valve proving activated, but 2 inputs assigned (set parameter 23
7 to pressure
switch-max or POC)
5
Valve proving not possible
Valve proving activated, but 2 inputs assigned (check parameters
236 and 237)
81
V1 leaking
Check to see if the valve on the gas side is leaking Check wiring to see if there is an open-circuit
83
V2 leaking
Check to see if the valve on the burner side is leaking Check to see if the pressure switch for the leakage test is closed
when gas
pressure is present Check wiring for short-circuit
14
#
POC
0
POC open
Check to see if the valve’s closing contact is closed
1
POC close
Check wiring Check to see if the valve’s closing contact opens when valve is controlled
64
POC open – prevention of startup
Check wiring to see if there is a line interruption. Check to see if the valve’s closing contact is closed
19
80
Combustion pressure, POC – start prevention
Check to see if pressure switch has closed with no combustion pressure present Check wiring for short-circuit
20
#
Pressure switch-min (Pmin)
0
No minimum gas /oil pressure
Check wiring for line interruption
1
Gas shortage – start prevention
Check wiring for line interruption
21
#
Pressure switch-max (Pmax) / POC
0
Pressure switch-max (Pmax):
Max. gas / oil pressure exceeded
POC:
POC open (software version ≤ V02.00)
Check wiring to see if there is a line interruption. POC: Check to see if the valve’s closing contact is closed.
