Part 8 Super SEL Controller Maintenance
To ensure safe and trouble-free operation of your Super SEL system, a regular maintenance and inspection program should be
implemented. Be sure to turn OFF the power before initiating any maintenance or inspection work. An inspection is recom-
mended at least once every 6 to 12 months. However, depending on the environment, a more frequent inspection schedule may
be advisable.
(1) Inspection Guidelines
• Check and make sure that the power supply to your Super SEL Controller is maintained at 90 ~ 127V.
• Check the controller vents and clean any accumulated dirt or dust.
• Check the controller cable (controller
→
axis) and make sure there are no loose screws or disconnections.
• Check for loose controller mounting screws. Tighten if necessary.
• Check each cable (axis cables, general I/O cables, system I/O cables, power supply cable). Check for loose connections,
damage, or excessive wear. Replace if necessary.
(2) Recommended Spare Parts
It is advisable to keep a small supply of spare parts. In critical applications, it may be advisable to keep an entire spare
Super SEL Controller on hand. The following spare parts are recommended:
• Cables
• Batteries* (Ni-Cd batteries have a general shelf life of about 6 years but this varies depending on use conditions and
environment )
(3) Memory Backup
When the controller is fully charged, backup memory is guaranteed for 3 months. In actuality, the backup memory is not
erased for 6-8 months but if the controller is to be left for a long period (more than 3 months) without having current run
through it, please take precautions to save your program, position data, and parameters. To fully charge the controller if it
does not contain any data, you will need to leave the controller with the power ON for 3 days.
If the memory is erased, the system's preset parameters will be set but the actuator will not run properly in this condition.
