Prior to initial commissioning, the rated motor current must be set on the
overload relay by means of the current dial (￫ table 2 on page 28).
CAUTION

If the overload relay is installed at a cool location (e.g. -5 °C) and
the motor is installed at a warm motor installation site
(e.g. 40 °C), it is possible that there will be a delayed release
during an overload if the devices are operated in the lower
current setting range.
The overload relay also offers the option of using the Reset selector knob
to choose between an automatic restart "A" and a manual reset "H".

A
Figure 10:Switching options of the Reset selector knob
The overload relay is factory-set to position "H", which prevents an
automatic restart. In position "H", the relay must be reset manually after
it has tripped, by pressing the selector knob.
The overload relay is provided with a Test button that contains a double
function.

The auxiliary contact 95-96 is opened by pushing the Test button, and can
thus be used to switch off the contactor relay.
The function of both auxiliary contacts can be tested in current-less state
by pulling the button.
