We have a system with MD4 connected by master bus to MC3. We have a XC23 connected to the MC3 via expansion on different bus to master.
On ignition switch on the system appears fine and all outputs and inputs into XC23 are OK, during engine start there appears to be a dip in voltage which causes the XC23 module to show 3 red, 1 amber LED flash (can error / timeout). When we get this error flash, IQAN run says system health is OK under the XC23 and MC3 modules and IQAN design shows the outputs on XC23 going true and false as expected. XC23 module outputs however are non functional, the module is in error state and refusing to operate outputs whilst the LED flash sequence above is active.
There are no logs in the MC3 for failed communication with XC23.
Are there any recommendations for how to resolve this? Is this normal behaviour for a dip in voltage on XC23? All other modules appear to be unaffected by voltage dip, its almost as if XC23 does not recover and outputs are non functional even though IQAN design thinks they are? Would pulsing 'enable' property just after engine start re-enable the module in event of this error flash?
Running IQAN Design 4.07 with machine voltage 24V dipping to around 10/12V on startup.
