not to overtighten the screw.

• The following serves as a general guideline for when to replace the battery:
About 3 years when using the controller under standard operating conditions (operat-

±
2
°
C) with the controller ON
About 10 years when using the controller under standard operating conditions (operat-
ing temperature: 23
±
2
°
C) with the controller OFF
Using the controller in a higher operating temperature will shorten its service life.
• Setups are held in memory even if the BAT LED is blinking.
• The controller operates in one of two ways when memory contents are damaged.
(1) “ G .R E S” is displayed when the controller is turned ON and regular operation is
not started.
(If this happens, press
ENT
to execute a general reset. This restores parameter set-
ups to factory settings and clears the program setup.)
(2) Regular operation is started when the controller is turned ON, and one or both of
alarm codes A L q 6 and/or A L q 7 is displayed.
