1. Be sure the control housing is properly grounded.
2. Armature connections must not be switched or broken while the control is on. Serious control damage may result.
3. For non-speedpot applications, the input connection to the LO, WIPER, and HI terminals must not be grounded!
Serious control damage may result from a grounded input.
Do not attempt to perform Hi-pot test across AC lines with control in circuit.
This will result in immediate or long term damage to the control.
WARNING: ALL POWER MUST BE TURNED OFF BEFORE PROCEEDING!
1. Recheck all wiring. Accidental grounds, loose or pinched wires on armature or speedpot wires may damage the control
when power is applied.
2. Check to see that incoming service is of correct voltage.
3. Turn speedpot to zero (fully CCW).
4. Turn power on, and advance speedpot while observing motor. Power must be off before step 5 can be accomplished!
5. If motor rotation is incorrect, turn power off at external disconnect and reverse +ARM and -ARM connections.
6. Check for satisfactory operation throughout the speed range.
7. If operation is satisfactory, no readjustments are needed.
8. If instability or surging is observed, or if maximum speed is higher than desired, see "TRIMPOT ADJUSTMENT CHART " on
page 5.
9. For other problems, consult page 10, "IN CASE OF DIFFICULTY".
DO NOT use for Permanent Magnet Motor. This supplies +Field voltage for a SHUNT WOUND
MOTOR (refer to fi eld voltage table). For motors with dual voltage fi eld (ie. 50/100V or
100/200V), make sure highest value is connected.
FIELD VOLTAGE TABLE
VAC INPUT
VDC FIELD
Connects to high side (white wire) of Speedpot (CW end). This is internal +12 volts. For
start-stop applications, the connection between this terminal and Speedpot HI can be
opened and closed by a SPST switch. INPUT MUST NOT BE GROUNDED!
Connects to wiper (red wire) of Speedpot (center lead). For Voltage Follower applications, this
INPUT MUST NOT BE GREATER THAN +12V MAXIMUM AND MUST NOT BE GROUNDED!
Connects to Low side (orange wire) of 5K Speedpot (CCW end). This input is raised and
lowered by the MIN. trimpot (5K). Electronic speed input (voltage follower) may be referenced
to Speedpot LO if the MIN trimpot adjustments are to be active. Otherwise, inputs may be
referenced to -ARM, which will bypass the MIN trimpot. INPUT MUST NOT BE GROUNDED!
