LS SERIES SERVICE MANUAL
ISSUE 4.0 DIAGNOSTIC MODES 1
11. DIAGNOSTIC MODES
11.1 General
The main use of the internal Engineer's Diagnostic Mode is to calibrate a loadcell or an
extensometer.
It is also required to reprogram the EEPROM on the Motor Drive PCB if this has been replaced
during servicing.
The machine also has a PC Diagnostic Mode that can be used to check the operation of the ADC
and to measure the power supply voltages without using a voltmeter or opening the machine.
THE DIAGNOSTIC MODES ARE SPECIFICALLY FOR SERVICE ENGINEERS AND IT IS VERY
IMPORTANT THAT CUSTOMERS DO NOT USE OR ARE INFORMED OF THESE FEATURES.
WARNING
CARE MUST BE TAKEN to ensure that accidental damage does not occur to either the
mainframe, loadcell or calibration equipment when calibrating a loadcell.
11.2 Selecting the Diagnostic Mode
If a "Full" Control Console is fitted, then the diagnostics screens are similar to a Plus Series
Control Console. Therefore the Machine, Loadcell and optional extensometer can be
configured / calibrated in exactly the same way as for a Plus Series Machine.
However, please note that the engineers code has now changed.
The code is now "2646 67" or "BOGN OR".
Note that the space between the 2 groups of characters indicates that a pause of approx. 1
second needs to be allowed between the 2 groups.
Refer to section 12 for details about using the "Full" Control Console diagnostic mode.
If a Hand Held Remote is fitted, then the "Normal" diagnostic mode is not available and all
configuration and calibration MUST be performed using the NEXYGEN Plus 3 Software
Console.
Refer to section 13 for details about using the NEXYGEN Plus 3 diagnostic mode.
