Service centre requirements

Product feedback

Receiving feedback from Service Centres about the types of field problems encountered is an important part of product

development. To assist us with improving the product, we ask that a Service Report be returned to us each month. With this

information, we can accurately identify trends in the field and offer appropriate technical support.

We also encourage you to provide us with your comments about the product. We value your feedback.

Only qualified Service Centres are authorised to carry out service work on Tru-Test weigh scale indicators.

Warning!

Static discharge can damage some components on the indicator. Such damage may degrade an

electronic component and may result in faults developing within that component over time. When working on

an indicator, ensure that correct anti-static procedures are used.

-Use a wrist band and earth strap.

-Work only on a grounded bench top.

-Use a suitable lead-free anti-static soldering iron and solder sucker.

-Store PCAs and LCDs in anti-static bags.

Technical bulletins

Technical bulletins are prepared as needed. They should be read in conjunction with the service manual. Technical bulletins are

available on the service website www.service.tru-test.com

The current technical bulletins cover:

•Span calibration guide

•Updating firmware

•Cell codes

•Cloning the data on the 5000 series weigh scale indicator

•LCD dead pixels

Returning a product

Before a product or assembly is returned to Tru-Test for service or analysis, please request a Return Authorisation (RA) number

so that one can be allocated. The RA number will ensure that we are ready for the product when it is received and assist us in

providing efficient and prompt service. Please mark all packaging with the RA number.

Changes to product

In June 2017, the LCD on ID5000 and XR5000 indicators was discontinued in favour of an LCD which had better contrast and

brightness. Indicators with a serial number of <510,000 (a number between 0 and 510,000) will have been manufactured with

the old LCD. Indicators with a serial number of >510,000 (a number after 510,000) will have been manufactured with the new

LCD. The serial number can be found on the back of the case:

It is important that you check the details of the indicator you are servicing, as the spare parts and repair procedures

differ considerably.

Here are the key differences between the spare parts provided for the two types of indicator:

Indicators with serial number <510,000 Indicators with serial number >510,000

Case front assembly has a window. The LCD is positioned

behind the window.

Case front has no window. The LCD is affixed directly to the

case front assembly using a sticky rectangular gasket (fitted to

the case front).

The old PCA has been discontinued. The new PCA can be

used on the old model indicator.

New PCA

LCD FPC does not have a connector LCD FPC has a connector on one end.

Different LCD.

Different LCD. It comes with a sticky rectangular gasket which

is used to affix the LCD to the case front.

The black, rubber gasket which surrounds the LCD is

provided as a separate part.

The LCD does not have a black, rubber gasket.

Servicing procedures

When servicing an indicator with a serial number <510,000, replace parts with their like equivalent, with the following

exceptions:

•LCD - If the LCD requires replacement, replace the whole indicator with a new one. This repair

may

be covered under

warranty. To find out more, see the technical bulletin

5000 series indicators – LCD dead pixels

available on the service

website www.service.tru-test.com. The reason that the whole indicator must be replaced is that the new LCD does not fit

fit into the old case and there are also many other associated spare parts which are required to perform this repair. For this

reason, it is more economical to replace the entire indicator. If you have stock of old LCDs in your inventory, these should

be used up first.

•PCA – The old PCA has been discontinued so when you order a new one, it will always be the same part, regardless of the

serial number. If you have stock of old PCAs in your inventory, these should be used up first.

When servicing an indicator with a serial number >510,000, replace parts with their like equivalent. Do not attempt to

fit parts that are only suitable for <510,000.
