334 ACOPOSinverter P84 User's Manual 2.10
2.9 Servicing
2.9.1 Service
The ACOPOSinverter P84 requires no preventive maintenance. It is however recommended to regularly carry out
the following operations:
• Check the condition and tightness of the connections.
• Make sure that the temperature around the unit remains at a permissible level and the ventilation is sufficient
(average useful life of the fans: 3 to 5 years depending on the operating conditions).
•
Keep the inverter free of dust.
2.9.2 Assistance during maintenance, fault display
If a problem occurs during the installation or during operation, first check whether the recommendations regarding
environment, mounting and connections have been followed.
The first discovered faults will be stored and displayed and the inverter is locked.
The change of the inverter into fault mode may be displayed decentrally via a logic output or a relay. These can
be configured in the menu
[INPUTS/OUTPUTS CFG]
(I-O-) . See for example
[CONFIGURATION R1]
(r1-) .
2.9.3 [DIAGNOSIS] menu
This menu can only be accessed with the graphic display terminal. It shows the detected errors and their causes
in full-text and can be used for the implementation of tests.
2.9.4 Clearing the fault
In the case of a non-resettable fault, interrupt the voltage supply of the inverter.
Wait until the display has been completely cleared.
Determine the cause of the error and correct the error.
The inverter is released after a fault as follows:
•
By switching off the inverter until the display is completely cleared , then switching on again
• Automatically in the cases that are described for the function [Aut. Restart] (Atr-)
• Via a logic input or a control bit with assignment to the function [FAULT RESET] (rSt-)
•
By pressing the STOP/RESET on the graphic display terminal.
2.9.5 Menu [MONITOR] (SUP-)
Displays the inverter status and its current values to avoid faults and detect the causes of faults.
You can use the integrated operator terminal to access the menu.
2.9.6 Spares and repairs
Please contact your local B&R office.
