13.2. Disposal
13.1. Disassembling the product
Observe the safety instructions given in Sections 2 to 8 and Section 13 when decommissioning and
disassembling the unit.
Careless disposal of the unit may be cause pollution.
Please therefore dispose of the unit in accordance with the national requirements that apply in your
country.
To protect the electrical equipment there are two low-current fuses in the unit. When a fuse blows for
the first time, this may be due to ageing. In this case we recommend replacing the defective fuse with
a new one. If the fuse blows again, the fault can be located and repaired using the following chart. A
low-current fuse must be changed by specialist personnel.
The low-current fuses must comply with EN 60127, dimensions 5 x 20 mm.
14. Troubleshooting
Please note the following instructions:
•
Proceed systematically and purposefully when troubleshooting, even when under the pressure of
time.
In the worst case, randomly and indiscriminately dismantling and changing settings may result in it no
longer being possible to determine the original cause of the fault.
•
Get an overview of the unit’s operation in conjunction with the overall installation.
•
Try to clarify whether the unit provided the required function in the overall installation before the fault
occurred.
•
Try to find any changes to the overall installation in which the unit is installed:
1. Have the unit’s operating conditions or operating range been changed?
2.
Have any changes (e.g. reconfigurations) or repairs been performed on the overall system (installation,
electrics, control) or to the unit? If yes: what?
3.
Has the unit been operated correctly?
4. How does the fault appear?
•
Form a clear idea of the cause of the fault. If necessary, question the immediate operator or the instal
-
lation operator.
If you have not been able to remove the fault, please contact the manufacturer. The contact
address can be found at www.

manual.

14.2. Fault diagnosis chart
If a fault occurs on the unit one or more fault messages will appear on the display. Move between the
various faults with buttons A (▲ and ▼). A fault is acknowledged with button B (▲). It is not possible
to use the control unit until all of the faults have been removed and acknowledged. Depending on
the priority of the fault, the installation will either switch off or continue working with the last settings.
The following faults might be shown on the display:
