Operation

3.1

Selector switch

The selector switch is used for adjusting the operating mode of the EM-HP.
Switch position Operating mode
0 The speed control signals of the controller relays 1 ... 4 are
copied and emitted as speed control signals (PWM) over the
0
HE outputs 1 ... 4 of the EM-HP.
Additionally, the corresponding relays 1 ... 4 of the EM-HP
are switched on.
9 The speed control signals of the controller relays 1 ... 4 are
copied and emitted as speed control signals (0-10 V) over the
0
HE outputs 1 ... 4 of the EM-HP.
Additionally, the corresponding relays 1 ... 4 of the EM-HP
are switched on.
8 ... 1 No function. The HE outputs 1 ... 4 of the EM-HP emit a 0 %
speed control signal. Relays 1 ... 4 of the EM-HP are switched
0
off.
