When the 17th error occurred
The 17th error is stored in Error history No.1 and 3600 (the start address of Error history No.1) is stored in 'Latest address of
error history' (Un\G2).

(Un\G2): 3600

• When the storage areas for the error history are full, data in 'Error history No.1' (Un\G3600 to Un\G3609) is
overwritten in order and recording of error history continues. The history data before the data overwriting is
deleted.
• The same processing is executed to the alarm history.
• The registered error history is cleared by powering OFF of the temperature control module or resetting the
CPU module.
