F. Vo ltage Following – An isolated

analog voltage can be used in lieu

of main speed potentiometer.

Connect signal to terminals “SIG"

and “COM.” Note: Te rminal “COM"

is common. A positive signal to

terminal“SIG” will produce a

positive output to motor.

A negative signal to terminal

“SIG" will produce a negative

output. A 0 to ±10VDC is required

to operate control from 0 ± full

output. Note: Jumper J4 must be

in the “10V” position. Note: An isolated signal voltage must be used or

catastrophic failure can result. (A bipolar signal isolator, model SIMG [KB P/N

8832], is available as an option from your distributor.)

G. Enable Start/Stop Circuits – The KBMG-212D contains a 2-wire stop circuit

(Enable), which is used to electronically bring the motor to a “stop.” An isolate

single contact closure is required. If an isolated contact is not available, it may be

necessary to use an isolation relay.

*Note: If 2-wire start/stop circuit is not used, a jumper must be wired to EN

and COM or control will not operate.

WARNING! Do not use Start/Stop or Enable functions as a safety

disconnect. Use only an AC line disconnect for that purpose.
