provided one side of the DC voltage source is grounded
to the same reference point as terminal C.
CONTROL CIRCUIT CHECK
Since an Advantage motor controller can be controlled
with an AC signal of 24 to 120 volts at terminals 3 and P,
a high impedance fault in the control circuit that bypasses
the STOP or START pushbuttons so as to supply voltage
in this range can cause controller malfunction, i.e., the
fault causes the controller to turn on or the fault nullifies
the STOP button. Check pushbutton stations for liquid
buildup and the leads to 3 and P for voltage when none
should be present.
CONTROL POWER AND TERMINALS, Cont’d
Control power terminals for the motor controller are shown
in Figure 3. All the terminals must be supplied by the
same phase. The preferred source is a control power
transformer whose primary windings are connected across
phase L1-L2, although phases L2-L3, phase L3-L1, or
phases A, B, and C will provide satisfactory performance.
See Figure 13. In any case, the power supplied to terminals
3 and P must be from the same phase as the power to
terminals E and C, except that a DC signal in the range
of 5 to 125 volts (24 to 96 volts for Model E or later) may
be supplied to terminals 3 and P for remote control,
