Maintenance and Installation
8.1
General
VPP 21-type operator terminals are maintenance-free. A few parts are subject
to wear and must be replaced after a certain number of operating hours.
WARNING
Maintenance work in the device is only permissible by skilled staff!
If hardware and/or software components have to be exchanged, please contact
the Bosch Rexroth Service or ensure that only skilled staff changes the re‐
spective components.
Include the following measures in the maintenance schedule:
●
Clean the screen surface at least once a week with an anti-static cloth or
window cleaning agent containing denatured alcohol.
WARNING
Dissolution of the keypad surface and the display seal through contact
with solvents!
Do not use any solvents (e. g. paint thinner)!
●
At least once a year, check all plug and terminal connections for proper
tightness and damage. Verify that lines and cables are not broken or
squeezed. Replace damaged parts immediately.
●
Check the fan at least once a year.
DANGER
Risk of injury through rotating fan impeller!
Keep hands and fingers clear of the fan impeller, and do not insert any items.
Concerning spare parts function compatibility is ensured for at least
5 years.
8.2
Hard Disc
The hard disk is plugged in the connector field of the VPP 21 box. Thus, the
hard disk can easily be exchanged.
WARNING
Loss of data!
Backup all required application data as well as operating system settings to an
external storage medium!
WARNING
Risk to damage the operator terminal by electrostatic discharges!
Comply with all ESD-protection measures during working with modules and
components! Avoid electrostatic discharges!
To store user data and to avoid the re-installation of the operating
system and application programs after a hard disk exchange, you
should back up the well-working hard disk at regular intervals.
