G. Enable Switch Connection
Safety Warning!
Do
not use Enable or
Start/Stop contacts as a safety
disconnect since they are not
fail-safe. Use only the AC line
for this purpose. See figure 13.
If a Start/Stop function is
required, remove SIMG Enable
jumper J1 and wire a switch to
EN and COM terminals of
SIMG TB1. When the switch is
opened, the control will stop.
When the switch is closed, the
control will operate.
H. Tachometer Generator Connection
See figure 8 on page 10. To wire a 7V or 50V per 1000RPM tachometer generator
to the SIMG, connect the positive (+) side of the tachometer generator to terminal
“T2” and the negative (-) side of the tachometer generator to terminal “T1“ of the
SIMG.
Note: If the positive (+) and negative (-) tachometer generator connections
are not connected as described above, the motor will run at full speed only.
I. Motor Field Connection
If a shunt wound motor is used, the motor field wires connect to F+ and F- terminals
on the SIMG. To access these terminals, cut out the field tab of the SIMG finger-safe
cover at three (3) places as shown in figure 14 on page 17.
