9.6 MANUAL START SWITCH
CONNECTION (CON1) – The
Manual Start Mode is used to
manually start the drive or restart
the drive (reset) if a fault has
occurred. To operate the drive in
the Manual Start Mode, remove
the factory installed jumper on
CON1 and install the 2-wire
connector (supplied). CON1 is
located on the lower PC board.
The connector must be wired to a
momentary switch or contact, as
shown in Figure 21, on page 19.
In the Manual Start Mode, the drive will trip
due to all faults (Overvoltage,
Undervoltage, Short Circuit, and I 2 t) and
remain tripped even when the fault is
cleared. To Start/Reset the drive, the
switch or contact must be manually
closed. Also, the drive must be restarted
each time the AC line is interrupted.
For Automatic Start, see Section 6.2,
on page 15.
Notes: 1. See Section 11.2, on page 22.
Also see Section 12.2, on page 23. 2. The
drive can be factory programmed for
Run/Stop operation with momentary con-
tacts.
9.7 FORWARD-STOP-REVERSE SWITCH
CONNECTION (CON2) – The drive can
operate using a Forward-Stop-Reverse
Switch, Contact, or Open Collector.
9.7.1 Models KBVF-27, 29 – Remove
the factory installed jumper on
CON2 and install the 3-wire
connector (supplied). CON2 is located on the lower PC board. The connector must be wired to
a “maintained” switch or contact. See Figure 22. Also see Forward/Reverse Speed Selection, in
Section 6.3, on page 15.
If installing the SIFVR Signal Isolator, see Section 9.7.2.
Note: The drive can be factory programmed for momentary contact operation.
9.7.2 Models KBVF-45, 48 – Wire the Forward-Stop-Reverse Switch as shown in Figure 16, on
page 18. If using Form “C” Contact or Relay, wire the circuit as shown in Figure 23. If using
Open Collector, wire the circuit as shown in Figure 24.
9.8 ENABLE SWITCH CONNECTION (CON2) – The drive can be started and stopped with an Enable
Switch (close to run, open to stop). Remove the factory installed jumper on CON2 and install the 3-
wire connector (supplied). CON2 is located on the lower PC board. The connector must be wired to a
“maintained” switch or contact. See Figure 25, on page 21.
