coil unit
"P1" displayed on PZ-01RC?
Yes
PZ-61DR-E is connected?
Yes
0206, 2600, 2601, 5109,
or 0900 displayed on PZ-61DR-E?
No
Refer to the service handbook
of the Lossnay unit for details.
Cause
Some error has occurred on PCB
B of the Dx-coil unit. (LED11 on
PCB B blinks.)
Some error has occurred in the
Lossnay unit.
( LED11 on PCB B blinks nine
times.)
Faulty connection of connector
CN20 on PCB A of the Dx-coil unit
A break or short in a lead wire for
connector CN20
Power is not supplied to PCB B of
the Dx-coil unit.
( LED12 on PCB B is unlit.)
Failure of the transformer for PCB
B of the Dx-coil unit.
(LED12 on PCB B is unlit.)
Failure of PCB B of the Dx-coil
unit.
Failure of PCB A of the Dx-coil
unit.
No
No
Yes
See (2).
See the Lossnay service handbook.
Check the connector connection of CN20
on PCB A.
Check the lead wires for connector CN20.
• Check the connection of power terminal
TB6 (L and N) on PCB A.
• Check the connection of power supply
connector CN1 on PCB B.
• Check the connection of transformer con-
nectors CN2 and CN4 on PCB B.
Measure the coil resistance of the trans-
former with a tester. If the breaking of the
coil is detected, replace the transformer.
If no error is detected after checking the
above items, replace PCB B (GU-01-E).
When the lighting status of the LEDs on
PCB B is normal, and no error is detected
on CN20 connection and lead wires, re-
place PCB A (IF013).
