0312582_EcoSword_V4.0, 03-05-2021
Cause
Defective gas control valve.
There is not enough or too much supply
voltage during 60 seconds.
The measured voltage between live and
neutral must be 230 V
(-15%,
AC
+10%).
The supply voltage between live and
earth must be between 110 V
230 V
(-15%, +10%)
AC
Damaged wiring/open circuit.
Sensor is not (correctly) connected.
Damaged wiring and/or defective sensor. Replace the wiring and/or sensor.

Short circuit in the sensor circuit.
Short circuit in the sensor circuit.
Measure
-
Make sure that there is no flame after
the gas control valve has closed.
-
If there is a flame, the gas control
valve must be replaced.
-
Make sure that the supply voltage on
the controller is correct.
-
If the supply voltage is above or below
the stated tolerance and the error
persists, contact your maintenance
and service engineer.
and
AC
-
Install an isolating transformer.
See measure of error F03 - Switch is not
closed when fan is running during pre-
purge.
-
Make sure that the connector is
connected to J3.
-
Make sure that the wire is connected
to the sensor.
-
Make sure that the connector is
connected to J3.
-
Make sure that the wire is connected
to the sensor.
Replace the wiring and/or sensor.
