4.4 Using the positioner in a humid environment

Introduction

CAUTION

Never clean the positioner with a high pressure cleaner since the IP66 degree of protection

is not sufficient for this.

This information contains important notes for the installation and operation of the positioner

in a wet environment with frequent and heavy rains and/or continuous tropical dew. The IP66

degree of protection is no longer adequate in this environment, especially when there is a

risk of water freezing.

Favorable and unfavorable mounting positions

Avoid the unfavorable mounting positions:

● To prevent fluids seeping through during normal operation of the device, e.g. through

exhaust air openings.

● Otherwise the digital display becomes poorly legible.

Figure 4-3 Favorable and unfavorable mounting positions

Additional measures to prevent liquids from seeping through

Take additional measures to prevent liquids from seeping through if the conditions force you

to operate the positioner in an unfavorable mounting position.

Additional measures required to prevent liquids from seeping through depend on the

selected mounting position. You may also require:

● Gland with sealing ring, e.g. FESTO: CK - 1 / 4-PK-6

● Approximately 20 to 30 cm plastic hose, e.g. FESTO: PUN - 8 x 1.25 SW

● Cable tie; the number and the length depend on the local conditions.
