10-12 RTC (Real Time Clock)
The AFC3000 Unit is equipped with an RTC (real time clock) for holding date and time data.
・
Model ANG-RTC
・
Backup power source Electric double layer capacitor
・
Backup duration in power OFF state Approx. 1000 hours
・
Power ON time needed for full charging of clock unit 1 hour
Be careful when using spare controllers, etc., because the time setting inside a Unit will be cleared if the
control power of the Unit is not turned on for 2 months or more.
Please perform time adjustment periodically because the clock loses time at a
rate of approximately 10 minutes a month.
