Changing the Battery

Electric Drives and Controls | Bosch Rexroth AG
The semiconductor fuse cannot be replaced!
A semiconductor fuse is used to protect the device. Once the fuse has
been tripped, the device must be disconnected from the supply voltage
to allow the semiconductor fuse to regenerate. At an ambient tempera-
ture of 20 °C (68° F), the regeneration takes approximately 20 sec-
onds. The higher the ambient temperature, the longer the regeneration
takes.
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.
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.
