Notes:
1. Phase Loss Detection: Models KBVF-23P, 24P, 29, 45, 48.
2. Requires AC line restart.
3. With DVF Modbus Communication Module Installed.
4. All LED flash rates after recovered faults are 1 sec. On / Off.
5. Drive will require manual restart to return the Status LED color to its normal flashing green state.
Problem Solution
No air flow

6. If one motor is running and one is not, replace the
faulty motor.
7. If all motors are not running, check for approx. 220
VAC output voltage. If there is no voltage and the
green lights are on and slowly flashing, replace the
AC inverter. (Remember this is three-phase: test
from lead to lead. Do not test to ground.) U to V, U
to W, V to W. If you lose voltage on one of these
legs, replace the AC inverter.
8. One bad motor could cause the steady-flashing
green light to change. Disconnect all motors and
run one motor at a time to find the bad motor.
9. Motors should be running counter-clockwise.
Check that all motors are running the correct
direction. If not, change the two output terminals to
obtain correct phase.
