For Start/Stop Switch with normally closed
stop contact, set Jumper J9 to the “NC”
position. See Figure 8 on page 14 and
Figure 9. Also see Section 6.8 on page 18.
5.6 Automatic Restart –
Automatic restart
requires the elimination of the Start/Stop
Switch. Remove the white, black, and red
wires from Terminals “RUN”, “COM”, and
“STOP”. The wires may be taped and left
inside the drive. The switch assembly may
be removed if a liquidtight seal is used to
cover the hole in the front cover.
To eliminate the Start/Stop function,
hardwire Terminals ”RUN” and “COM”
with the jumper that is provided. Be sure
Jumper J9 is set to the “NO” position. See
Figure 10.
WARNING!
Using a jumper to
eliminate the Start/
Stop function will
cause the motor to
run at the Main Speed
Potentiometer setting
when the AC line is
applied.
5.7 Voltage Following
Connection –
An
isolated 0 – 5 Volt DC
analog signal input can
also be used to control motor speed in lieu of the Main Speed Potentiometer. The drive
output will linearly follow the analog signal input. Wire the signal input positive lead (+) to
Terminal “P2” and the negative lead (-) to Terminal “P1”. With external circuitry, a 0 – 10
Volt DC analog signal can also be used. See Figure 11.
Note:
For signal following operation, the Minimum Speed Trimpot (MIN) must be set fully
counterclockwise.
WARNING! The signal input
must be isolated from the AC
line. Earth grounding signal
wiring will damage the drive
and void the warranty.
5.8 Enable Circuit Connection –
The drive can also be started
and stopped with an Enable
circuit (close to run, open to
stop). See Figure 12.
