Figure 3-5 Favorable and unfavorable installation positions

If conditions oblige you to operate the positioner in a unfavorable

installation position, you can take additional precautionary measures to

prevent penetration by water.

NOTE
Never clean the positioner with a high pressure water jet because the

IP65 degree of protection is inadequate protection for this.

The necessary additional measures to prevent penetration by water

depend on the installation position chosen and you may additionally

require:

screw--type gland with sealing ring (e.g. FESTO: CK –1 / 4–PK–6)

plastic hose approx. 20 to 30 cm (e.g. FESTO PUN-- 8X1,25 SW)

cable straps (number and length depends on local conditions)

Procedure

Connect the pipes in such a way that rain water which runs along

the pipes can drip off before it reaches the terminal strip of the

positioner.

Check the electrical connections for perfect firm contact.

Check the seal in the housing cover for damage and contamination.

Clean and replace if necessary.

Mount the positioner if possible so that the sinter bronze silencer

faces downwards on the underside of the housing (vertical installa-

tion position). If this is not possible, the silencer should be replaced

by a suitable screw--type gland with a plastic hose.

Assembly of the screw--type gland with plastic hose

Unscrew the sinter bronze silencer from the exhaust air opening on

the underside of the housing.

Screw the screw--type gland mentioned above into the exhaust air

opening.
