B. J3 – Motor Armature Voltage – Select the desired armature voltage by placing J3 in the

proper position, “90" or “180.” Note: For 115 volt AC Line input, the armature voltage
must be set to “90.” For 230 input, the armature voltage normally is set for “180.”
However, it is also possible to set the armature voltage to “90" for step-down operation.
(See fig. 2 and table 4.)

*A 90VDC motor can be used with a 230VAC line. However, speed range may be reduced and
motor overheating may result.

C. J4 – Armature Current – Select the J4 position (1.7, 2.5, 3.3, 5, 7.5) closest to the rated

motor current. (Note the maximum output current is set to 150% of the J4 position, which
may be readjusted using the FWD CL and REV CL trimpots.)

D. J5 – Analog Input Voltage –

Jumper J5 is set to the “15V” po-
sition for potentiometer operation.
If the control is to be operated
from an isolated 0 – ±10VDC
signal, set J5 to the “10V” posi-
tion. (See sec. V, F, p. 7.) (See
fig. 3.)
