Performing a Calibration Cycle
Broadly speaking, the procedure for a calibration cycle is as follows:
1. Before starting battery calibration, you have to select SIMATIC battery
calibration under Control Panel > Power Options, than deactivate the
options Activate battery alarm when power level reaches in the tab Alarms
under Control Panel > Power Options.
2. Battery operation: Discharge the battery until the battery LED on the device
changes from red to green. To do this, remove the power supply from the Field
PG P4.
Duration: max. 3 hours.
3. Power supply operation: Fully charge the battery (without interruption) until
the battery LED on the device changes from orange to green. This will take a
maximum of 4 hours if the device is switched off. (Optional: to reduce the
recharge time, switch off the device if possible).
You can carry out an automatic calibration cycle with the “Field PG” panel (see
section 3.5).
