Leakage controller VPS 504 S02
For C 160 and C 210 burners
Working principle :
Prior to each burner start-up, the
control unit checks for possible leaks
between safety and main valves by
increasing distribution pressure.
Electrically, the leakage controller is
serially connected between the
thermostatic circuit and burner control
and safety unit.
Installation :
Directly on valve.
Program stages :
On stoppage, safety and main valves
are closed.
On thermostat stoppage, the leakage
controller is turned on and booster
increases distribution pressure by
20mbar.
After no more than 30 seconds
operation :
If leakage test is OK; yellow light
–
comes on and current is released to
feed the burner's control and safety
unit, which then starts its cycle.
If leakage test is NOK; red light
–
comes on and no power is fed to
the control and safety unit.
Control cycles have to be restarted
manually. Change valve if defect
persists.
Setting :
The controller requires no on-site
setting.
Working test :
While controller is working
· Open pa pressure take-off. Leak
caused prevents superpressure from
building up and safety unit locks
after 30 seconds.
· Reclose pa pressure take-off.
· Release controller safety by
pressing red indicator light.
Leakage test restarts and, after 30
seconds, yellow indicator lights up and
powers up the control and safety unit,
which begins its cycle.
