i. KBPC-240D SIMPLIFIED OPERATING INSTRUCTIONS
IMPORTANT – You must read these simplified operating
instructions before you proceed. These instructions are to
be used as a reference only and are not intended to replace
the detailed instructions provided herein. You must read the
Safety Warning on page 2 before proceeding.
1. CONNECTIONS.
A. AC Line – Wire AC line voltage to terminals L1 and L2. Be sure jumpers J2A and J2B
are both set to the correct input line voltage 115 or 230 VAC. Connect ground wire
(earth) to green ground screw on case.
B. Motor.
1. Permanent Magnet (PM) Type. Connect motor armature leads to A1(+) and A2(–).
Be sure jumper J3 is set to the proper position “90V" for 90 volt DC motors and
“180V" for 180 volt DC motors. Note: 180 volt DC motors must be used with 230
VAC line, 90 volt motors can be used with a 230 VAC or 115 VAC line. See sec.
II, C, on page 7.
2. Shunt Wound Motors. Connect motor armature as above. Connect full voltage
shunt field wires (90 volt motors with 100 volt fields and 180 volt motors with 200
volt fields) to F1 and F2. Connect half voltage field wires (90 volt motors with 50
volt fields and 180 volt motors with 100 volt fields) to F1 and L1. See sec. IV, C,
on page 11.
2. SPEED OR TORQUE MODE.
Jumper J1 is factory set for speed control operation (SPD). For torque control, set J1 to
TRQ position. See sec. II, A, on page 5.
3. MOTOR CURRENT.
Jumper J4 is factory set for 10 amp motors (10A). For lower amperage motors, place J4
in the proper position. See section II, D, on page 8 for details. Note: The factory setting
for Current Limit is 150% of the nominal current setting, e.g., if J4 is selected for 10 amps,
the actual CL setting will be 15 amps.
4. TRIMPOT SETTINGS.
All trimpots have been factory set in accordance with figure 1, page 3 and table 1, page 5.
5. DIAGNOSTIC LED’s.
After power is turned on, observe LED’s to verify proper control function. See sec. VIII on
page 15.
6. ARMATURE FUSE.
The correct size armature fuse must be installed, depending on the rating of the motor.
Control will not operate if fuse is not installed. See section V, B on page 13 and table 6 on
page 12.
7. START/STOP SWITCH.
The KBPC contains a built-in manual start/stop switch. This switch must be used to start
the control each time AC power is lost. To override this function see sec IV, G, p. 12.
