III. Connections to the SIMG

Safety Warning! Do not use FWD-STOP-REV contacts as a safety discon-

nect since they are not fail-safe. Use only the AC line for this purpose.

Note: SIMG Enable jumper J1 must be installed, or a connection must be made

between EN and COM terminals of SIMG TB1 in order for the KBMG to operate.

A. Voltage Following

– Uses a

voltage source to vary motor

speed. See figure 10. Connect

the voltage source to TB1 ter-

minals SIG and COM. When a

0V DC signal is applied, the

control will operate at the mini-

mum set speed (set by the

OFFSET trimpot on the SIMG).

When a 10V DC signal is

applied, the motor will operate

at the maximum set speed (set

by the MAX trimpot on the SIMG).

Applying a positive (+) signal to SIG terminal, with respect to COM terminal, will oper-

ate the motor in the forward direction.
