2.2 Electrical connections
- Employ a specialist to connect the machine to the mains supply. The local connection regulations
must be adhered to. The cable should not lie loosely on the ground after it has been laid.
Specifically observe the direction of rotation of the motor shaft (visible at the vane
marked by the red arrow, see Fig. 3.9). Direction can be reversed by exchanging
2 phases in the mains supply cable.
2.3 Motor protective relay
- Fig. 2.2 -
The motor protective relay is triggered upon overload of the motor and switches off the power sup-
ply of the motor. This is indicated on the trigger display window -2-.
• Yellow display, invisible: relay not triggered
• Yellow display, visible: relay triggered
- Should the motor protective relay have triggered, the machine must first be switched off with the
ON/EMERGENCY-STOP button. Then determine and eliminate the cause.
Once the cause has been eliminated, the motor protective relay can be reset by
pressing the reset key -1-, - Fig. 2.2 -.
While doing so, ensure that all protective systems are installed on the machine
and all tools have been removed from the machine.
2.4 Block mode for drive motor sliding connecting rods
- Fig. 2.3 -
Disconnection of the three-coil regulation of the DC motor occurs when the motor has been blocked
for 10 sec.
The block mode is set back by switching off the mains voltage.
• -3-, Green
Illuminated when the mains voltage is adjusted and released (ready).
• -4-, Red
Illuminated when the current limit has been reached (overload).
• -5-, Red
Illuminated once the block protection has switched off the controller (fault)
