Malfunctions And Alarm Signals; In-House Repairs - ACL OR-PC Series Manual

5.2 Maintenance intervals and wearing parts
All units are designed for 24/7-operation. This results in highest requirements to components and
materials. To ensure the reliable operation under these harsh conditions we recommend to repla-
ce the following components prophylactically:
Component Replacement after
Mass storage 30.000 hours of operation
Display panel 30.000 hours of operation
Grommets in cable cover if necessary
The lifetime of your flash memory depends on various external aspects. High ambient temperature, a high storage utili-

zation as well as a large number of writing operations, especially when writing lots of smaller files, will strain your memory
additionally. Depending on your operation environment other intervals might be reasonable. We would be glad to submit
an offer for these maintenance tasks.
No consumables are required.

5.3 Malfunctions and alarm signals

Shut the unit down if you discover any mechanical damage to the housing, display or service
cables. The unit should be checked by a qualified service partner in this case because operating
the unit with damaged components can cause further damage.
Disconnect the unit from the network immediately in the following cases and get in contact with
the manufacturer or authorized service technician:
• unusual odor or smoke
• a high level of heat escaping from the unit
• damage to the power cable or plug
• faulty unit functioning although you followed the operating instructions
• substantial changes in the unit's behavior that indicate that it needs service
• mechanical damage to the unit or to its frontal glass plate (such as due to a fall)
• unusual noises from the unit during operation
Restart the unit in the following situations and check the environment for strong sources of EMC
radiation and for any non-conformities with the minimum distances from transmitters listed in
Section 3.3:

5.4 In-house repairs

Diligent testing of the unit is guaranteed by the manufacturer. He is responsible for safety-related
characteristics within the legal limits only if repairs and modifications are performed by personnel
authorized and trained or supervised by ACL and if the unit and its accessory are used according
to the rules of the intended use. Therefore, there are warranty seals on or in your unit. Once a seal
is broken an expiring warranty has to be assumed. Service personnel may be trained and certified
by ACL only.
The units are designed to enable the customers' technical personnel that is capable to deal with
electrical installations to exchange the components listed in this section. Other components shall

Incorrect repairs are a safety risk. You should not apply your own setting or adjusting methods
if they do not comply with the unit's specifications or use components not supplied or approved
by ACL GmbH because that might damage the unit. Finally, it is not allowed to make any changes
or modifications in the unit or take actions to boost performance beyond the original settings
without the manufacturer's permission.
