Controller Properties

The EDP-C2 is activated with 24v manual command instead of traditional 230v
therefore making it safer for the operator. He have is own control voltage.

If the electromagnet wires disconnect the controller will automatically lower the
voltage close to 0 VDC within less than 0.5 seconds to help protection of both
operator and equipment.

The controller will activate the field current only when needed to prevent
premature wear of the generator.

The controller offers the possibility of augmenting electromagnetic efficiency by
having two power levels.
1.
One called ``High Tension’’ which can generate up to 30% more voltage
than the standard electromagnet voltage during a predetermined time (3-
10 seconds) permitting to pick up more material at a time.
2. The other called ``Transport Tension’’ which is about 15% less voltage
than the standard electromagnet voltage. This tension is used to carry
objects that have already been lifted thus keeping the electromagnet
cooler.

The demagnetisation is done by polarity inversion. A first dopping voltage is
applied and followed by a second cleaning Voltage.
This two voltage are controlled parameter for each .

The controller may provide two droping modes and two Loading modes (see next
page).
