1 QUICK-START INSTRUCTIONS
Important: You must read these simplified instructions before proceeding. These instructions
are to be used as a reference only and are not intended to replace the details provided herein.
You must read the SAFETY WARNING, on page 5, before proceeding.
1.1. Connections (See Figure 3, on page 14).
Note: There are no AC Line or Armature fuses supplied with this control. See Section,
1.1.2.
1.1.1 AC Line – Connect AC line voltage (115 or 230 VAC) to terminals L1 and L2.
Connect ground wire (earth) to the green ground screw.
1.1.2 Fusing – The KBRG-212D does not contain AC line or armature fusing. It is
recommended that a 20 Amp fuse or circuit breaker be installed on each AC line
conductor not at ground potential. Do not fuse ground or neutral wires.
1.1.3 Ground Connection – Earth ground the control chassis using the green ground
screw that is provided on the control,s heat sink (near TB2).
1.1.4 Motor (See Figure 3, on page 14).
a. Permanent Magnet (PM Type). Connect motor armature leads to M1+ and
M2-.
Note: Motor performance and efficiency, including brush life, can be adversely affected
when using 90 volt motors with a 230 VAC line. Contact motor manufacturer for
derating information.
b. Shunt Wound Motors. Connect motor armature leads as above. Connect
full voltage shunt field leads (90 volt motors with 100 volt fields and 180 volt
with 200 volt fields) to F+ and F-. Connect half voltage field leads (90 volt
motors with 50 volt fields and 180 volt motors with 100 volt fields) to F+ and
L1.
1.2 ENABLE/INHIBIT– The control can be electronically stopped and started with this circuit
function. To “Stop” the control, Terminals must be connected in the required position, by
selecting the type of mode, via J9. See Figure 8B and Section 6.10, on page 18.
In the Enable Mode, the control can also be started and stopped with an Enable circuit
(the Enable circuit functions opposite to that of the inhibit circuit; Inhibit: open to start,
close to stop, Enable: open to stop, close to start). The Enable function can also be
established by wiring a contact in series with the high side of the Main Speed
Potentiometer lead connected to Terminal P3. See Figure 8A and Section 6.10, on page
18.
1.3 SPEED OR TORQUE MODE: Jumper J5 is factory set for Speed (SPD) control operation.
For torque control, set J5 to the Torque (TRQ) position. See Section 7.3, on page 20.
1.4 JUMPER SETTINGS: All jumpers are set for the KBRG-212D version. The control is
factory jumpered for the Enabled mode. See Section 7, on page 19.
1.5 TRIMPOT SETTINGS – All trimpots have been factory set. See Figure 1, on page 10 and
Section 10, on page 25.
1.6 SIGNAL INPUT – Connect potentiometer or analog input to TB1, terminals “-15,” “+15”
“SIG,” and “COM” according to Section 6, on page 16.
