Honeywell FEMA TAM Series Assembly And Operating Instructions Manual Download Page 15

1. Basic equipment

In general adjustment procedure of
switchpoints at screw terminal housing is
similar to procedure for plug connector
housing.

Fig. 8.

Screw terminal housing

CAUTION

Switch off power before opening.

After removal of the casing-cover (1), the
adjustment screw (3) and thus also the
setpoint (4) can be adjusted to the
required value by means of a screwdriver.

After adjustment of switchpoint, replace
cover and tighten 4 cover screws.
