Connection - power unit
The connections of the power unit are on connector X2. Power unit
and control unit of the SmartTurn are separated from each other
internally. Semiconductors are used for switching the outputs.
If the use of safety functions in accordance with DIN EN ISO
13849-1 is necessary to safely stop the drive, then outputs A1, A2
and activation of the power contactors must be separated through
coupling relays, see Fig. 16.
The SmartTurn power unit must only be directly wired into the plant
controller from power contactors, if for operating the turntable no
safety functions in accordance with DIN EN ISO 13849-1 are
required, see Fig. 17.
The connected power contactors must be wired with a varistor
contactor circuit. Other protective circuits must not be used,
because they impermissibly delay the contactor dropout time. The
contactor dropout time should not exceed 25 ms.
Technical data - Siemens Sirius reference contactor
Sirius S00 3RT10 1.:
Power consumption - magnet coils at DC activation 3.3 W.
Contactor dropout time with varistor at DC activation ≤ 15 ms.
Sirius S0 3RT10 2.:
Power consumption - magnet coils at DC activation 5.4 W.
Permissible residual current at 24 VDC activation < 16 mA
Contactor dropout time with Varistor at DC activation ≤ 20 ms.
NOTE!
The connecting lines on connector X2 must not
have LED displays.
