Control terminals
Terminal U
S
The HF range is supplied by the rated control supply voltage U
s
with 24 V DC. The voltage may range from 19.2 V DC
to 30 V DC.
U
S
may be 32 V DC for a maximum of one minute.
Control terminals for DOL-, ROL- and R- types
The same voltage source (potential) must be used for the control supply voltage U
S
and the control inputs ON/R, L. Please
see Figure 21 Commissioning the control inputs of DOL-, ROL- and R- types. The reference point for the control inputs (U
S,
ON/ R, L) is terminal
⊥
.
Control terminals for DOLE- and ROLE- types
The control inputs (ON / R, L) are electrically isolated from the control supply voltage (U
S
,
⊥
). The same voltage source
(potential) may be used for the control supply voltage and the control inputs. Please see wiring diagram in figure 21 commis-
sioning the control inputs of DOL-, ROL- and R- types.
Terminal ON / R, L
The signal for starting or switching off the motor is applied at the control input.
For direct on-line starters there is one control input, labeled 'ON'.
For reversing types terminal 'R' is for forward running (right rotation), 'L' is for reverse running (left rotation).
As can be seen in the following figures, the control input(s) must be connected with:
• A switch
• A 24 V DC power supply
• The reference point for the control inputs (U
S
, ON/ R, L) is terminal
⊥
.
