Service and repair 

This section describes what the end-user must do in case of required service or repair. 

NOTE

The LT-1000 NRU does not require any scheduled maintenance or service. Make sure that the 
product is installed, as described in this manual, before making contact to the distributor or 
dealer for further assistance. 

 
For troubleshooting the LT-1000 NRU, see Troubleshooting on page 33. 
 

If the LT-1000 NRU for some reason does not work as described in this manual, make contact to the 
distributor or dealer, from where the product was originally bought. The distributors or dealers will have 
experience and know-how to assist with further technical support and troubleshooting. 

 

Contacting the distributor/dealer: 

1)

 

Make sure to have the product name (LT-1000 NRU), Part Number (P/N: 51-100142), and the unit 
serial number (S/N: XXXXXXXX) identified. The unit serial number is listed on the outside of the 
device. 

2)

 

Write a technical report about the observation or error. If possible, attach a picture of the installed 
product and include a wiring diagram. If possible, make a diagnostic report with the LT-Service Tool 
(see Configuration using LT-Service Tool on page 29). 

3)

 

Send all information to the local distributor or dealer. 

 

IMPORTANT:  Unless otherwise agreed, the end-user shall always coordinate service and repair issues 

directly with the distributor or dealer. This practice also applies for returning of products for 
service and repair. 

 

All information that will get back to Lars Thrane A/S, either directly or indirectly, will be handled with 
confidentiality. End-user sensitive data will not be shared with any third party without prior written 
acceptance from the involved parties.
