CONTROLS
– ELECTRICAL
CURRENT CONTROL/RED PILOT LIGHT
This is the main switch, located next to the ammeter on the front panel. With the current control
in any position other than "Off", the red pilot light will glow indicating that the unit is ready for
operation. Current values will be indicated by the
ammeter reading when the external magnetizing circuit (loop) is complete.
OVERLOAD CIRCUITBREAKER
This control is located within the unit and is an automatic resetting type overload relay. It will
interrupt the current to the transformer whenever the rated duty cycle is exceeded.
AMMETER
The ammeter, located on the front panel, registers the current flowing in the magnetizing
circuits. An automatic solid state switching circuit allows a single meter to provide accurate
current readings for both AC and half-wave DC magnetizing currents.
OUTPUT CONNECTORS
Half-wave DC current is obtained by connecting the magnetizing cables to the "Common" and
"Half-Wave" connectors. A.C. current is obtained by connecting to the "Common" and "AC"
connectors. Always insert and then twist cable connectors clockwise to lock in position.
CONTROL CABLE RECEPTACLE
This receptacle is located below the current control. Twist and lock the control cable in the
receptacle.
PROD CONTROL SWITCH
Various optional prod assemblies have a control switch built into the handle. It is connected
through a 20' cable and three prong twist lock plug to the control cable receptacle. It controls
the magnetizing current through the prods.
REMOTE CONTROL CABLE SWITCH
The optional remote control switch is attached trough a 20' cable and activates the unit with a
push button switch. This switch is required when using cables as
a coil.
CONTROL CIRCUIT FUSE
This fuse is located on the rear panel. Replacement can be accomplished from the outside.
After power has been turned off, unscrew the head of the fuse holder. Remove the fuse from
the holder by pulling out the fuse. Replace with a new fuse of proper rating and place back into
holder. Replace fuse holder head. This fuse will interrupt the 115 volt control circuit in the
event of an overload.
