Battery Operation

Battery Operation
If not connected to an external power supply unit, the SIMATIC Field PG P4 can
be operated with the internal battery pack.
1. Switch on the device. Make sure the battery is sufficiently charged before you
start work.
2. Work as usual with your SIMATIC Field PG P4.
3. In battery mode, the red signal of the battery LED indicates that the battery is in
low condition. Stop your work and save your data. There are only a few minutes
of battery operation remaining.
Notice
Do not start a work session in battery mode unless the battery is fully charged. This
is the only way of ensuring that the full on-battery operating time is available and that
you will be warned in good time when battery power is low. When connected to the
external power supply unit, the orange battery LED indicates that the battery is being
charged.
When connected to the external power supply unit, the green battery LED indicates
that the battery is fully charged and that charging has stopped.
The battery might be partially or totally discharged when you start commissioning (fro
example, running-down). Connect the device to the power supply unit and the unit to
mains to charge the battery.
As soon as the device is connected to mains via the power supply unit, the battery
is recharged.
Replacing the Battery
You can replace a run-down or defective battery with a new replacement battery:
1. Turn the Field PG P4 over and place it with closed display unit onto a flat mat.
2. Unlock and open the battery cover on the bottom of the casing.
3. Replace the battery.
4. Close the cover and turn the device over again.
Warning

Do not use a battery type other than that supplied. The battery is available as
