11.1.4 Function test of the valve
The valve must be checked for function after connecting the coil connector and before removing the lock
nut for connecting the high-pressure hose. The correct opening and closing of the valves can be proven by
means of this function test.
Initial state:
•
The lever for manual release is secured
•
The valve outlet is sealed gas-tight with the lock nut
A conventional hexagon socket wrench SW 3 and a lock nut with ventilation bore are required to carry out
the function test.
Function test
• Actuate the valve electrically by manual release for a short time (2 to 3 seconds) and then switch off the
power to reset the manual release and the control unit.
•
Loosen the bleeder screw with the hex socket wrench by half a turn. This bleeds the upper valve area
so that the valve audibly closes. However, the pressure in the valve outlet is maintained.
•
Carefully loosen the lock nut by approx. half a turn to bleed the valve outlet. An audible, brief gas leak
signals that the valve has opened correctly. This gas leak must stop immediately. Otherwise the
valve is not closed. In that case, the lock nut must not be removed under any circumstances.
•
If the valve does not close, it must be replaced. Contact BINDER Service.
• If the valve is functioning correctly, screw the bleeder screw back in a gas-tight manner.
