Gray holder

(13)Insert the body into the case.

Do not exert excessive force if the body cannot easily fit into the case. Also, make sure that the boards mounted on the body are not loose or twisted.

(14)Tighten the lock screw while slightly pushing in the controller’s console. Take care not to overtighten the screw.

(15)Turn the controller ON, and make sure that the BAT LED is out.

Note • 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- ing temperature: 23± 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.
