Solenoid Coil Replacement
Solenoid Coil Replacement
Before you start, make sure you have:
A replacement solenoid coil FC-COIL-0001
1. De-gas the loading post (see page 23).
2. Switch off the power supply to the loading post.
Never remove any electrical components without first
switching off the power to the loading post. Failure to turn off the power
could result in an electric shock.
3. Remove the flameproof box lid to gain access to the C4000 power
supply board.
4. Disconnect the solenoid coil wiring from the C4000 power supply
board.
Take basic anti-static precautions by wearing a wristband
with an earth strap.
5. Loosen the gland on the flameproof box that is clamping the solenoid
coil lead and pull the lead out of the gland.
Undo the nut on the top of the solenoid valve that is securing the coil and
remove the coil from the top of the valve
Install the New Solenoid Coil
1. To install a new solenoid coil, reverse the procedure above.
Before replacing the lid on the flameproof box, make sure that
the O-ring is not damaged and is seated properly in its groove. If the O-ring
is damaged and needs replacing, replace it with an O-ring of the same size
and specification (176 N70).
