nside the drive. The switch assembly may be
r
emoved if a watertight seal is used to cover
t
he hole in the front cover. After applying
power to the drive, momentarily set the
Start/Stop switch to the “START” position.
For Start/Stop Switch with normally open stop
contact, set Jumper J9 to the “NO” position
(factory setting). For Start/Stop Switch with
normally closed stop contact, set Jumper J9
to the “NC” position. See Figures 10 and 11.
A
lso see Section 6.8, on page 18.
Note: To eliminate the start/stop
function, hardwire Terminals ”RUN”
and “COM” with the jumper that is
provided. Set Jumper J9 to the
“NO” position. See Figure 12.
WARNING! Using a jumper to
eliminate the start/stop func-
tion will cause the motor to run at
the Main Speed Potentiometer set-
ting when the AC line is applied.
5.6 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 fol-
low the analog signal input. Wire the signal input posi-
tive 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 13.
*If a non-isolated signal is used, install the SIAC Signal
Isolator (Part No 9488). The SIAC accepts voltage
(0 to ±2.5 thru 0 to ±25 volts DC) or current
(4 – 20 mA DC) signal inputs. See Table 2, on page 8.
Note: For signal following
operation, the Minimum
Speed Trimpot (MIN) must
be set fully counterclockwise.
WARNING! The signal
input must be isolat-
ed from the AC line. Earth
grounding signal wiring will
damage the drive and void
the warranty. It is highly
recommended that the
SIAC Signal Isolator
(Part No. 9488) be installed when using signal following.
5.7 ENABLE CIRCUIT CONNECTION –
The drive can also be started and stopped with an Enable circuit
(close to run, open to stop). See Figur
e 14, on page 16.
