NOTE!

Start current for the engine’s system voltage

(the control module) is 10 A. Make sure that other
components in the installation are dimensioned for this
current.

Start contact

Contact type, closing (NO), spring biased.

Stop contact

Contact type, closing (NO), spring biased.

Via parameter setting, it can become energized during
operation. In that case, use contact type closed (NC).

Nominal rpm minus 120 rpm:

0.3–1.9 V
(preset value 1.17 V)

Nominal rpm plus 120 rpm:

1.9–4.7 V
(preset value 4.5 V)

1500 / 1800 rpm contact

This function allows a change of frequency from 50 to
60 Hz.

Contact type two position.

Idle contact

Contact type two position.

Closed contact provides idling speed (900 rpm).

Speed droop contact

The contact must be closed to obtain speed droop.
