No. 05500-00000 The P1 processing solution temperature exceeds the safety range (setting temperature + 1°C) after the
temperature adjustment is finished. (P1 thermosensor)
No. 05501-00000 The P2 processing solution temperature exceeds the safety range (setting temperature + 3°C) after the
temperature adjustment is finished. (P2 thermosensor)
No. 05502-00000 The PS processing solution temperature exceeds the safety range (setting temperature + 3°C) after the
temperature adjustment is finished. (PS thermosensor)
NOTE
• There is a specific process specification whose safe range of PS is the setting temperature + 7°.
1 Confirm that the value measured via Thermosensor Calibration is correctly entered.
2 Check whether the tank cooling fans (FAN 1 to 3) operate normally.
For cooling failure Manual No.
