Corrective Action
Check the wiring of the AC input power.
Check the ambient temperature, the cooling fan, and the clearances
around the unit.
If the error occurs intermittently, contact the Allen-Bradley Company
or replace the unit. Check that the harmonic filter is located on the
primary side of the line reactor and the secondary side of the line
reactor is connected to the RPS.
Check the wiring of the AC input power.
Check the ambient temperature, the cooling fan, and the clearances
around the unit.
If the error occurs intermittently, contact the Allen-Bradley Company
or replace the unit. Check that the harmonic filter is located on the
primary side of the line reactor and the secondary side of the line
reactor is connected to the RPS.
Check the wiring of the AC input power.
Check the ambient temperature, the cooling fan, and the clearances
around the unit.
If the error occurs intermittently, contact the Allen-Bradley Company
or replace the unit. Check that the harmonic filter is located on the
primary side of the line reactor and the secondary side of the line
reactor is connected to the RPS.
Check the wiring of the cooling fan for the master unit and the AC
reactor.
Verify that no foreign material is caught in the cooling fans for the
master unit and the AC reactor.
If the error occurs intermittently, contact the Allen-Bradley Company
or replace the cooling fan or the Power Interface Board (PIFS).
Make the phases (L
1
, L
2
and L
3
) of the AC main power same as
those of the control power.
If the error occurs intermittently, contact the Allen-Bradley Company
or replace the Power Interface Board (PIFS).
Error Cause
The Phase L
1
Power Module of the
master unit is faulty.
The Phase L
2
Power Module of the
master unit is faulty.
The Phase L
3
Power Module of the
master unit is faulty.
The cooling fan(s) of the master unit
and/or the AC reactor is (are)
defective.
The AC reactor is overheated
(1) .
The phases (L
1
, L
2
and L
3
) of the AC
input power of the master unit do not
match with those of the control power.
The Power Interface Board (PIFS) of
the master unit is faulty.

Signal
Error Cause
Phase loss occurred for the AC input
power.
Power loss occurred (The allowable
time for instantaneous power loss was
exceeded.)
No answer-back signal was received
from the main magnetic contactor.
An error was received from the Power
Interface Board (PIFS).
Corrective Action
Check the AC input power voltage and the line fuse.
Check that the set value of the Allowable Time for Instantaneous
Power Loss (F.012) is adequate. If no other problem is found,
increase the set value.
Check the operation of the main magnetic contactor.
Verify that the answer-back signal of the main magnetic contactor is
correctly wired to the sequence input signal terminal.
Verify that the connecter to connect the Regulator Board and the
Power Interface Board is correctly inserted.
