THREE-WIRE CONTROL WITH JOG OPTION
The contacts of a two-position NORMAL/JOG selector
switch can be added to the control circuit between points
2 and 3 of Figure 5 where an external electrical interlock
is used as the holding circuit. Install a #16 or #18 AWG
stranded wire jumper from 3 to P. Keep strip length to not
more than 1/4 inch.
Be sure to have jumper clear power
terminal.
Where the internal holding circuit is used, wire
as shown in Figure 9 or 10. No jumper is needed. Attach
and route twisted pair or shielded wires to a remote reset/
trip indicator module where provided.
With Communications
Attach a WPONI communications module and connect it
to the INCOM network daisy-chain fashion as shown in
Figures 4 and 10. Where IMPACC control is used, the sel-
ected switch must be a type that breaks one circuit before
making the other when switching from NORMAL to JOG.
When wired as shown in Figure 10, the motor can be
started and stopped via IMPACC, provided the selector
switch is in the NORMAL position. When the selector
switch is in the JOG position, the motor cannot be started
via IMPACC, but it can be stopped via IMPACC. However,
the motor will restart when the START button is pushed.
The starter can be reset via IMPACC with the selector
switch in either mode.
