Description and settings
Gas valve/leak testing device
Leak testing device
VPS 504 S02
How it works:
Before each activation of the burner the
test device is used to test the leak
tightness between the safety valves and
the principle valves by raising the
distribution pressure.
Electrically the leak tightness test device
is connected in series between the
thermostatic circuit and the burner’s
control and safety unit.
Setup:
Directly onto the valve.
Program cycle:
When the burner is switched off the
safety valves and principle valves are
closed.
When the thermostat is closed, the leak
tightness test device is switched on and
the booster increases the distribution
pressure by 20 mbar.
After running for a maximum of 30
seconds:
- The leak test is validated; the yellow
light comes on, a voltage is released
to power the burner control and safety
unit, which begins its program.
- The leak test is not validated; the red
light comes on, power is not supplied
to the control and safety unit.
- Manual intervention is required to
relaunch a test cycle. If the problem
persists the valve must be changed.
Settings:
The leak tightness test device does not
need any on-site adjustments to its
setting.
Operating test:
While the leak testing device is in
operation.
• Open the pressure connector
pa . The
leak generated prevents boosting and
after 30 secs the device will go into
safety mode.
• Reclose the pressure tap pa .
• Reset the leak tightness test device’s
safety catch by pressing the red
indicator.
The leak testing device restarts itself
and after 30 seconds the yellow light
comes on and the control and safety unit
is powered up and will start its program.
