Elektra Beckum TF 100 M Commissioning 1-Phase Power Supply, Direction Of Rotation, Switch

7 Commissioning

7.1 1-Phase Power Supply

This machine must be connected to an earthed outlet and operated on a residual current device (RCD) of 30 mA capacity. Supply voltage required 230V ±5% 50 Hz. Protect circuit with a fuse 16 A time-lag. A supply line lead cross section of min. 3 x 2.5 mm2 is required.

7.2 3-Phase Power Supply

A 5-wire (L1-L2-L3-N-Earth) supply system is required. Connect with the 16A CEE industrial type plug to an earthed outlet equipped with a residual current device (RCD) of 30 mA capacity. Supply voltage required 400V

±5% 50 Hz. Protect circuit with 3 fuses 16 A time-lag. A supply line lead cross section of min. 5 x 1.5 mm2 is required.

7.3 Direction Of Rotation

For machines with single-phase motor the direction of rotation is factory set. On machines with a three-phase motor the direction of rotation must be checked after connection to the power supply. Start motor briefly. The spindle, when viewed from the top, must turn counter-clockwise. To change the direction of rotation interchange 2 of the current conduction leads (black and/or brown). Do not connect the yellow-green earth lead to any of the current conducting leads.

Note:

With a wrong direction of rotation there is danger of accident. Check direction of rotation carefully. Have phases interchanged only by a qualified electrician!

7.4 Switch

This spindle moulder is started by actuating the green push-button and stopped by actuating the red button.

7.5 Overload Protection

In case of an overload the build-in motor protection relay switches the power off. Let motor cool off for approx. 10 minutes before starting again.

7.6 No-Voltage Release

The switch is equipped with a no-volt release solenoid (magnetic switch) to prevent start-up after a power failure. It the machine is not connected to the power supply the switch does not engage. In the event of a power failure the machine has to be restarted by switching ON again.

7.7 Dust Collection

This spindle moulder must be connected to a dust collector. - The fine dust of beech or oak is classified as cancer-causing.

The dust collector this spindle moulder is to be connected to must provide for a minimum air flow rate of 16 m/sec at the machine's dust extraction outlet.

The dust extraction outlet's nominal diameter is 100 mm.

7.8 Dust Collector Automatic Start

The electrical installation must provide for automatic starting of the dust collector when the spindle moulder is switched on, and for a 20 second switch-off delay after the spindle moulder is switched off.
