Maintenance and Installation
8.9
Battery
The built-in battery preserves the data in the SRAM and supplies the
real-time clock with power. The minimum battery life is 5 years, even
under unfavorable operating conditions. When the battery runs down,
the message "Change battery" is generated automatically.
We recommend you change the battery approximately every 4 years
as part of the regular maintenance work. A pre-assembled battery
including connector can be obtained directly from Bosch Rexroth (order
designation: VAS04.1-001-002-NN, MN: R911316662).
If the "Change battery" message is detected too late, data in the SRAM
may have already been lost. For this reason, after changing a battery,
always check data such as editable passwords, parameters in the sys-
tem variables, data sets of the recipes and entries in the message sys-
tem.
8.9.1
Changing the Battery
To ensure that the data in the SRAM and the time are preserved, it is
possible to change the battery under operating voltage. Observe the
corresponding safety notices!
1. Remove the screws on the rear panel of the device and lift off the
enclosure cover.
2. Remove the adhesive tape securing the battery.
3. Disconnect the connector from the battery and remove the dead bat-
tery.
4. Plug in the cable for the new battery.
5. Use the included adhesive tape to attach the new battery to the en-
closure.
6. Place the enclosure cover back onto the device.
7. Carefully tighten the screws of the enclosure cover.
8.9.2
Battery Disposal
You must always return old batteries to a dealer or to a returns depot
set up for this purpose by the public waste disposal body or a licensed
battery dealer for recycling. Only dispose of dead batteries in public or
commercial collection boxes. The battery is drained when the message
„Change battery“ appears on the display of the device.
To prevent short circuitry in the collection boxes, insulate the poles of
each battery with insulation tape or put each single battery into a plastic
bag.
