Safety

General safety

All work on electrical systems or operating equipment may only
be carried out by a specially qualified electrician according to the
applicable electrotechnical regulations.

The safety of the system in which the SENSORswitch is integrated is
the responsibility of the operator.

Notes and symbols used

Warning notes in relation to personal injury / material damage are
formulated according to the "SAFE” principle. This means they
contain information on the type and source of the hazard, potential
consequences as well as how to avoid and avert danger. The
following hazard classifications apply in the safety notes:

DANGER

Danger designates a hazardous situation, which, if
ignored, will lead to death or serious injury. The symbol
next to the warning indicates the type and source of the
danger.

WARNING

Warning designates a hazardous situation, which, if
ignored, may lead to death or serious injury. The symbol
next to the warning indicates the type and source of the
danger.

CAUTION

Caution designates a hazardous situation, which, if
ignored, may lead to injury. The symbol next to the
warning indicates the type and source of the danger.

NOTICE

Notice designates a situation, which may cause material
damages and impair the product’s function if attention is not
paid.

TIP

Tip provides additional useful information about the handling of
the product.

General description

The supplied switch can have options that differ from those shown in
this manual. This does not affect the function. The CHT1 is equipped
with two different colored LEDs. The LEDs are actuated differently
depending on the pin configuration.

Assembly

Requirements: Mounting surface is level and
clean.

► Disconnect the system from its voltage

supply and secure it against being
switched on again.

► Set the desired position of the

SENSORswitch and drill the hole
according to the drilling pattern.

► Unscrew the lock nuts (B) from the

SENSORswitch (A).

► Insert the SENSORswitch into the

prepared hole and screw the lock nuts
(B) back on.

► Position the SENSORSwitch (A) and

tighten the lock nuts with max. 1 Nm.

► Connect the SENSORswitch (A)

electrically according to the connection
plan.
