4. Preparation for Operation
4.1 Charging of the battery
The battery built into the controller is fully charged by energizing continuously.
The battery charging time will depend on the specifications of the battery used by the customer.
STS2 lights up green when 48 hours continuous charging is completed.
Caution
When the power supply is cut for longer than 1 hour after fully charging the battery, and is applied
again, STS2 lights up orange.
4.2 Setting the power supply period by switch setting
The power supply (backup) period is set by the combination of SW (switches).
To operate the actuator manually during back-up, make sure that the cycles of the motor is within the
range of "Maximum cycle of the motor when the power supply is cut" If the motor rotation limit is
exceeded, or the backup period is exceeded, the information of the encoder position will be lost/
corrupted. In this case, an alarm is generated.
