WE-7 Operating Instructions
3
The cover is designed to fit best into the cast groove with the wide side to the
right (as illustrated) of the Yoke body. Furthermore, the feeler button, on the
raised portion of the switch cover is farthest away from the switch connections.
To insert the Switch Cover, bend the cover longitudinally, and slip the top
of the cover into the grove. Use a small screwdriver to
help
the bottom of the
cover into the groove after the top is in place. During factory assembly, the cover
is slightly lubricated/moistened. Ensure the lubricant does not dry, and create a
vacuum in the Switch Cavity, which causes the Switch to stick.
3. Field Selection –
The WE-7 provides the operator with either an AC or DC
Field, simply by changing the position of the AC/DC switch on the Control Panel.
While in DC mode, the Field Intensity is Infinitely Variable, with the use of the
Intensity Knob, which is also located on the Control Panel. An illustration of the
Control Panel is show bellow.
DO NOT CHANGE THE FIELD WITH THE PUSH BUTTON DEPRESSED
Mounted to the rear of the Control Panel, and inside the Junction End Cap, are
the Control Board and Heat Sink. To remove the Control Panel and Junction
End Cap, Fasteners #1 and #2 are the only ones to be removed. The Control
Printed Circuit Board directs AC voltage directly into the Yoke’s Coil (AC Mode)
or Converts it to DC and again directs it into the Coil (DC Mode). The DC
Intensity Controls are contained on the same Printed Circuit Board, and adjusts
the DC Voltage and thus the lifting power of the Yoke.
Adjusting the DC Intensity Knob while the Yoke is activated is completely
acceptable. However, the Field Selection Switch (AC/DC) should not be touched
