Remedy
Nitrogen does not hold in the system
• O-rings on camera leaking
• O-rings on rotary actuator leaking
• O-rings between cap, sheet metal
and air motor housing leaking
• Nitrogen valve leaking
• 8-pole cable connector leaking
• Screw connections on the grommet
with voltage transformer
• Screw connections between rear
rotary actuator and quick connector
with grommet
(for voltage transformer)
• All cable glands
Topping up with nitrogen.
In the water bath, check the camera,
rotary actuator, valve and rear
distributor for leaks.
Replace the O-rings concerned in each
case.

• Camera cable or its screw
connection leaking
Pressurise each bubble with compressed
air and check whether the pressure in
the nitrogen ring is rising.
Nitrogen 0.8 bar / compressed air 2.5
bar
Dismantle the bladder in the affected
area and check the cables and screw
connections for leaks. Seal or replace
leaking parts.

Nitrogen cannot be filled
• Nitrogen valve defective
Try to fill nitrogen via the valve or use a
camera dummy.
Replace valve
