Indicators and operating controls:
TEST OK
1
2
TEST
= TEST phase (yellow)
OK
= operating signal (green)
1
= fault valve 1 (red)
2
= fault valve 2 (red)
= reset button
Main switch on.
Apply mains voltage to terminal 1.
▷
If one or both fault lamps (red) are lit, wait ap-
prox. 5 s then press the reset button. The fault
signal goes out.
Start the tightness test.
▷
Mode
, test before burner start-up.
4
Voltage at terminal 3.
Or
▷
Mode
, test after burner run.
5
Mains voltage at terminal 1 and renewed test
after switching off the voltage to terminal 3.
The test begins:
▷
LED
TEST
is lit.
After test, if the valves are tight:
▷
LED
OK
is lit.
MODE 1: voltage at terminal 4.
Or
MODE 2: voltage at terminal 4 does not arrive
until voltage is applied to terminal 3.
After test, if the valves are leaking: voltage at termi-
nals 8 and 9.
▷
LED
1
is lit.
Or
▷
LED
2
is lit.
Power failure
▷
If the power fails briefly during the test or during
operation, the tightness test will restart auto-
matically.
▷
After a power failure during a fault, both red fault
lamps will be lit.
Assistance in the event of
malfunction
CAUTION
Electric shocks can be fatal!
– Before working on possible live components, en-
sure the unit is disconnected from the power supply.
– Fault-clearance must only be undertaken by
authorized trained personnel.
– (Remote) resets may only be conducted by
authorized personnel.
▷
Faults may be cleared only using the measures
described below.
