List of Error

At a Glance

The messages displayed on the diagnostics screens are used to assist with debugging. These messages must be concise and are sometimes ambiguous (as different faults may have the same consequences).

These diagnostics are on two levels: module and channel, the latter being the most explicit.

The lists below show the message headings with suggestions for identifying issues.

List of the Module Error Messages

The table below provides a list of the module error messages.

Fault indicated	Possible interpretation and/or action.
Module failure	The module has a error. Check the module mounting. Change the module.
Faulty channel(s)	One or more channels have a fault. Refer to channel diagnostics.
Self-test	The module is running a self-test. Wait until the self-test is complete.
Different hardware and software configurations	There is a lack of compatibility between the module configured and the module in the rack. Make the hardware configuration and the software configuration compatible.
Module is missing or off	Install the module. Fasten the mounting screws.

BMX EHC 0200 Module Error

The table below provides a list of error that may appear on the BMX EHC 0200 module.

Language object	Description
%MWr.m.c.2.0	External fault at inputs
%MWr.m.c.2.1	External fault at outputs
%MWr.m.c.2.4	Internal error or self-testing.
%MWr.m.c.2.5	Configuration Fault
%MWr.m.c.2.6	Communication Error
%MWr.m.c.2.7	Application fault
%MWr.m.c.3.2	Sensor power supply fault
%MWr.m.c.3.3	Actuator supply fault
%MWr.m.c.3.4	Short circuit on output 0
%MWr.m.c.3.5	Short circuit on output 1

List of Channel Error Messages

The table below gives the list of error messages at channel level.

Fault indicated. Other consequences.	Possible interpretation and/or action.
External fault or counting input fault: encoder or proximity sensor supply fault line break or short circuit of at least one encoder differential signal (1A, 1B, 1Z) specific fault on absolute encoder Outputs are set to 0 in automatic mode. Invalid measurement message.	Check the sensor connections. Check the sensor power supply. Check the sensor operation. Delete the fault and acknowledge if the fault storing is configured. Counting pulses or incremental encoder: preset or reset to acknowledge the Invalid measurement message.
Counting application fault: measurement overrun overspeed Outputs are set to 0 in automatic mode. Invalid measurement message.	Diagnose the fault more precisely (external causes). Check the application again, if necessary. Delete the fault and acknowledge if the fault storing is configured. Counting pulses or incremental encoder: preset or reset to 0 to acknowledge the Invalid measurement message.
Auxiliary input/output fault: power supply short circuit of at least one output Outputs are set to 0 in automatic mode	Check the output connections Check the input/output power supply (24V) Diagnose the fault more precisely (external causes) Delete the fault and acknowledge if the fault storing is configured
Internal error or channel self-testing: module faulty module missing or off module running self-test	Module fault has gone down to channel level. Refer to module level diagnostics.
Different hardware and software configurations	Module fault has gone down to channel level. Refer to module level diagnostics.
Invalid software configuration: incorrect constant bit combination not associated with any configuration	Check and modify the configuration constants.
Communication error	Check the connections between the racks.
Application fault: refusal to configure or adjust	Diagnose the fault more precisely.
