EMERGENCY BATTERY.
9.3 Operation of the emergency battery.
Central unit powered by the battery.
The battery only powers the central unit when a failure occurs at the power supply (a drop
of the 24 V). The Fagor battery provides an autonomy of about 20 minutes when it is fully
charged.
Response of the CNC with battery to mains failures
When a power supply failure occurs (drop at the 24 V) and there is a battery connected to
the central unit, the latter responds as follows:
• If the supply is interrupted for less than 2 seconds.
The CNC shows the corresponding warning and the system recovers fine. Errors may
occur at the CAN bus due to the lack of 24V at the remote modules.
• If the supply is interrupted for more than 2 seconds.
After the 2 seconds, the CNC shows the corresponding error and it initiates the automatic
shut-down sequence. First of all, the CNC stops any process in progress (program in
execution, tool change, etc.) and closes the CNC application. Then, the CCN shuts the
whole system down and, finally, deactivates the battery.
Recharging the battery.
The battery is charged from the central unit; DO NOT use any other device to recharge it.
The LED next to the connector blinks while the battery is being charged and it stays on when
the battery is charged. The charging process takes about 35 hours.
