Concentration of the PS4 tank
processing solution is out of range.
Throw away waste and 4L FRSS
water put PS4 tank with PS2 (No.4)
rack pulled out.
If this Message persists, consult your
technical representative.
Measurement result of solution
concentration is abnormal
(Causes of the error message)
1. PS4 solution concentration is
increased because the Solution is
in the PS1 to PS3 tank mixed with
the PS4 solution.
2. Poorly connected or broken
harness between the PS4 solution
concentration sensor (FS706) and
CTL7 on the CTL23 circuit board
3. Faulty FS706
4. Faulty CTL23 circuit board
5. PS4 solution concentration is
increased because the PS tank
partitioning plate or blade is
broken and the PS1 to PS3 tank
solution flows into the PS4 tank.
1. Collect waste solution and add 4
liters of FRSS to the PS4 tank. (If
the problem persists for a long
time, perform 2/3/4 below.)
2. Connect the harness correctly, or
repair or replace it.
3. Replace FS706.
4. Replace CTL23 circuit board. (If
the problem persists for a long
time, perform 5 below.)
5. Drain off the solution in the PS
tanks and replace the partitioning
plates or blode.

The temperature of the PS4 tank
processing solution is out of range.
Please wait a moment.
PS4 temperature exceeds the limit
(temperature setting ±2 °C).
Temperature control of the PS4 tank
is not completed.
(Causes of the error message)
1. Temperature control of the PS4
tank is not completed.
1. Wait until temperature control of
the PS4 tank is completed.

abnormal.
Shut down scanner with emergency
stop button and restart it. If problems
persist, consult your technical
representative.
Dryer fan rotation detecting function
is abnormal.
(Causes of the error message)
1. Poorly connected or broken
harness between the dryer fan
(F760) and PDB9 on the PDB23
circuit board
2. Faulty F760
3. Faulty PDB23 circuit board
1. Connect the harness correctly, or
repair or replace it.
2. Replace F760.
3. Replace the PDB23 circuit board.

Thermometer abnormal.
Shut down scanner with emergency
stop button and restart it. If problems
persist, consult your technical
representative.
Thermohygrometer is faulty.
(Causes of the error message)
1. Thermohygrometer (HS760) is
covered with an obstacle.
2. Poorly connected or broken
harness between HS760 and
CTL15 on the CTL23 circuit board
3. Faulty HS760
4. Faulty CTL23 circuit board
1. Remove the obstacle.
2. Connect the harness correctly, or
repair or replace it.
3. Replace HS760.
4. Replace the CTL23 circuit board.
