1. Error
Code
Open phase
2. Error
definition and error detection method
An open phase of the power supply (L1 phase, N phase) was detected at power on.
The L3 phase current is outside of the specified range.
The open phase of the power supply may not always be detected if a power voltage from another circuit is applied.
3. Cause, check method and remedy
4102
Cause
Check method and remedy
(1)
Power supply problem
Open phase voltage of the power supply
Power supply voltage drop
Check the input voltage to the power supply terminal block TB1.
(2)
Noise filter problem
Coil problem
Circuit board failure
Check the coil connections.
Check for coil burnout.
Confirm that the voltage at the CN3 connector is 198 V or
above.
(3)
Wiring failure
Confirm that the voltage at the control board connector CNAC is
198 V or above.
If the voltage is below 198V, check the wiring connection between
the noise filter board CN3, noise filter board CN2 and control
board CNAC.
Confirm that the wiring between noise filter TB23 and INV board
SC-L3 is put through CT3.
(4)
Blown fuse
Check for a blown fuse (F01) on the control board.
->If a blown fuse is found, check for a short-circuiting or earth fault
of the actuator.
(5)
CT3 failure
Replace the inverter if this problem is detected after the compres-
sor has gone into operation.
(6)
Control board failure
Replace the control board if none of the above is causing the
problem.
