2.4.4. Tool safety notice •
•
Wires, electrical and mechanical tools used to perform service work must be in accordance with the requirements for tools used and for the work to be performed. Damages to unit or environment might be caused with tools that are not in accordance with their laws.
2.5. SERVICE POLICY
Service is to be performed at the nearest Service Center or at customer location by trained service personnel or at the manufacturer's premises. All defective parts must be replaced with spare parts. Repairing of a board is not allowed. Defective products up to FR8: Customer should get a equivalent product as replacement unit, while the service work is being performed at a Service Center. The replacement unit is free of charge if the product is under warranty according to Vacon warranty terms. Defective products above FR8: They should be repaired by nearest Service Center at customer location, unless manufacturer declares otherwise. RAN-number: Any shipment of defective products and warranty claims to Vacon Plc must both be identified with a RAN-number issued (Return Authorization Number). Local Service Center sends a RAN-number request with necessary information via a PC-program (Vacon RAN) or fax to Vacon Plc. Vacon Plc responds to the request by giving instructions how to proceed. All shipments in a service case to and from Vacon Plc uses issued RAN-number. RAN-number issued must be used on all documents concerning the warranty claim. The shipment to Vacon Plc and shipment documents must be labeled with the RAN-number issued. The missing RAN-number in a shipment and shipment documents, might result in rejection of shipment and warranty claim. All Service Centers around the world are part of Vacon global service network and the local Service Center must have measures to reach customer satisfaction. Only spare parts, specified and approved by Vacon Plc must be used to replace defect ones. Boards will be repaired only at Vacon Plc. Service actions defined in a released SBU (Service Bulletin) authorizes repair or modification of the board mentioned. Warranty will be revoked from the unit, if repair actions have been done without proper authorization from Vacon Plc. 2.6. WARRANTY TERMS.
Warranty terms available at http://www.service.vacon.com/257942.html. 2.7. REPLACEMENT UNITS & SPARE PARTS
Spare part lists for service are listed at http://www.service.vacon.com/257927.html. Vacon Service Center or Partner will store replacement units needed for service purposes for fast response of service cases. The stock of the replacement units should

contain at least one unit of the biggest power size of every mechanical size up to FR8. Vacon Plc will compensate stock of spare units in case of unit under manufacturer's warranty has been delivered to replace of the defective unit. Service Center will store spare parts based on units sold and needed for service in their market / service area. If needed the Vacon Plc helps to select needed spares. The spare parts must be stored properly to prevent material loss due to mishandling. Always protect components and boards from ESD in all phases of the process by following general ESD instructions. 2.8. MAINTENANCE 2.8.1. RECOMMENDED MAINTENANCE ACTIONS
All technical equipment, as well as drives needs some amount of care taking and failure preventive maintenance. To maintain trouble free operation of the drive, environmental conditions, as well as load, line power, process control, etc. have to be within specifications, determined by manufacturer. If all conditions are as specified by manufacturer, there is no other concerns, but provide high enough cooling capacity for the power- and control circuits. This requirement can be met by making sure, that cooling system works properly. Operation of cooling fans and cleanness of the heat sink should be verified once in a while. Regular maintenance is recommended to insure trouble free operation and long lifetime of the drive. The following things should at least be included in the regular maintenance. TABLE 5. Maintenance interval
Interval 12 months (if unit stored) 6 - 24 months (depending on environment)
Maintenance Capacitor reforming, see separate instructions Check the input and output terminals and control I/O-terminals. Clean the cooling tunnel Check operation of cooling fan, check for corrosion on terminals, bus-bars and other surfaces
5 - 7 years
Check the door filters in the case of cabin installation Change the cooling fans Main fan Internal IP54 fan Cabinet cooling fan/filter
5 - 10 years
Change the DC bus capacitors

Recommended is also to record all actions and counter values with dates and time for follow up of maintenance. 2.8.2. RECHARGING CAPACITORS IN STORED UNITS
When complete units are stored without voltage being applied, the recharging of the capacitors should be done at least every 12 month by connecting the voltage into unit and keep unit powered minimum 1 h. If the storing time is much longer than one year, the recharging of the capacitors has to be done in a way that the possible high leakage current through the capacitors is limited. Best alternative is to use DC-power supply with adjustable current limit. Current limit has to be set for example to 300…500mA and DC-power supply has to be connected to the B+/B- terminals (DC+ to B+, DC- to B-) of the DC-link or straight to the capacitor terminals. NX models, which have no B+ / B- terminals, can be powered up as follows: •
Frame size FR8-FR9; DC-supply connected between two input phases (L1, L2).
DC-voltage has to be adjusted up to nominal DC-voltage level of the unit (1.35*Un ac) and has to be supplied at least 1h. If DC-voltage is not available and unit has been stored much longer than 1 year deenergized, consult factory before connecting the power. 2.8.3. RECHARGING STAND-ALONE CAPACITORS STORED
When using spare part capacitors from stock and it is known that they have been there over one year as voltage-free, the recharging of capacitors is easiest to perform before capacitors are installed inside a unit. DC-supply current limit is set to value 50…100mA and voltage is set up to rated value of capacitors. The recharging process can be then followed by monitoring the current meter of the DC-power supply. It is recommended to keep voltage supplied at least 1 h even that leakage current has already stabilized earlier.

Due high leakage resistance the dangerous voltage can remain in capacitors long time. Remember to discharge capacitors by using a proper resistors after recharging is finished.

4. FAULTCODES AND SOFTWARE 4.1. GENERAL
Testing and troubleshooting are one of the first steps in service / repair procedures to locate and identify defective part from the device. Troubleshooting gives good figure for further measures, what have to be done to recover unit back in decent condition and in an operation. Careful troubleshooting and testing in prior to repair saves total time and surely prevents additional consequential damages if done correctly. Troubleshooting in general level for the complete drive is described in this section. This section refers to checking instructions for respective frame size in its "NX-Appendix Manual". 4.2. FAULT CODES, POSSIBLE REASONS AND CHECKING TO BE DONE
Vacon NX-drive has a capacity to save last 30 faults codes and show them on display of control panel, if desired. There is always a reason or another for the tripping of the drive and it should be solved before to proceed in an operation and to avoid damages in equipment. Used fault codes are also described in "section 9.Fault tracing" of the Vacon NX frequency converter user manual. On flow charts below all numeric fault codes are described with an explanations and with measures to be done in different cases for solving the problem. Fault codes from F50 and above are generated from the application. They are not system software fault codes. Some fault codes in special system-software or applications do not have troubleshooting instruction. Instructions for such codes are available in respective software manual. 4.3. SOFTWARE REVISION INFORMATION
This troubleshooting section cover drives with Vacon standard software. Instructions in “FAULT CODES” on page 15 covers fault codes in software versions until "NXSV151" (11.55.6639) and "NXPV145" (12.26.7284).

6. START-UP AFTER REPAIR 6.1. EXTERNAL DC POWER WITHOUT MOTOR FOR FR4 TO FR13
Before preceding to test, check visually that all parts, wirings and connections are correct. There will be dangerous voltages present during this test. 6.2. TESTING WITH DC SUPPLY WITHOUT MOTOR CONNECTED:
Switch off DC-power supply Connect power supply's DC+ to unit's B+ main terminal. Locate an internal place for DC+ connection if drive is without DC+ terminal. Connect power supply's DC- to unit's B- main terminal. Locate an internal place for DC- connection if drive is without DC- terminal. Set power supply voltage setting to zero and switch on DC -power supply. Adjust voltage slowly to units nominal DC-voltage (1,35 x Un) Read following monitoring and system info values: Voltage of dc-link 1.8 (same as supplied DC voltage). Unit temperature V1.9 (estimate if it corresponds to environmental temperature) Software version (same as loaded to unit) Ready state or not Set parameter 2.7.4 (id 730) to 0 in standard application. This disables the input line supervision. Set the drive to RUN state. Change reference frequency from 0 to 50 Hz. Check the output frequency. Increase the DC voltage to tripping limit. Check for over-voltage fault (F2) indication on display. NOTE! DO NOT EXCEED OVERVOLTAGE TRIPPING LIMIT!
Switch off DC power supply and wait until DC-link has discharged!

6.3. LOAD TEST WITH MOTOR
Before preceding to testing check visually all parts, wirings and motor connections are correct. Connect main cables, motor cables and earth connections. Switch on AC supply. Select application and set correct parameters (e.g. motor). Don't set a too high value for current limit P2.1.5, too short time for acceleration time P2.1.3 or too short time for deceleration time P2.1.4. Run motor without load between from minimum to maximum frequency and measure output current with a current clamp. Compare current clamp values to unit's monitoring value V1.4. Load motor to nominal value, if possible, and compare current clamp value to unit's monitoring value V1.4. Check that fan operates normally and follow unit temperature from monitoring page V1.9.
