Error messages:

Whenever an error occurs in the system, it will propagate through the CAN bus or APG remote cable. Depending on whether it occurred during a method run or not, the other modules will be informed and stopped, or will remain idle waiting for the system to be ready again.

General errors

The following is a list of errors regarding all HPLC modules:

Message	Probable causes	Suggested actions
0062 – Timeout	The analysis was completed successfully, and the timeout function switched off the module as requested. A not-ready condition was present during a sequence or multiple-injection run for a period longer than the timeout threshold.	Check the logbook for the occurrence and source of a not-ready condition. Restart the analysis where required.
0063 – Shutdown	Leak detected in another module with a CAN connection to the system. Leak detected in an external instrument with a remote connection to the system. Shut-down in an external instrument with a remote connection to the system. The degasser failed to generate sufficient vacuum for solvent degassing.	Fix the leak in the external instrument before restarting the module. Check external instruments for a shut-down condition. Check the vacuum degasser for an error condition. Refer to the Service Manual for the degasser or the 1260 pump that has the degasser built-in.
0070 – Remote Timeout	Not-ready condition in one of the instruments connected to the remote line. Defective remote cable. Defective components in the instrument showing the not-ready condition.	Ensure the instrument showing the not-ready condition is installed correctly, and is set up correctly for analysis. Exchange the remote cable. Check the instrument for defects (refer to the instrument’s documentation).
0071 – Lost CAN Partner	CAN cable disconnected. Defective CAN cable. Defective main board in another module.	Ensure all the CAN cables are connected / installed correctly. Exchange the CAN cable. Switch off the system. Restart the system, and determine which module or modules are not recognised by the system.
0064 – Leak	Loose fittings. Broken capillary. Loose or leaking purge valve, inlet valve, or outlet valve. Defective pump seals.	Ensure all fittings are tight. Exchange defective capillaries. Ensure pump components are seated correctly. If there are still signs of a leak, exchange the appropriate seal (purge valve, inlet valve, outlet valve). Exchange the pump seals.
0083 – Leak sensor open	Leak sensor not connected to the main board. Defective leak sensor. Leak sensor incorrectly routed, being pinched by a metal component.	Contact Moyo Scientific Service.
0082 – Leak sensor short	Defective leak sensor. Leak sensor incorrectly routed, being pinched by a metal component.	Contact Moyo Scientific Service.
0081 – Compensation sensor open	Defective Main Board	Contact Moyo Scientific Service.
0080 – Compensation sensor short	Defective Main Board	Contact Moyo Scientific Service.
0068 – Fan failed	Fan cable disconnected. Defective fan. Defective main board. Improperly positioned cables or wires obstructing fan blades.	Contact Moyo Scientific Service.
0205 – Open cover	The top foam was removed during operation. Foam not activating the sensor. Defective sensor or main board. Rear of the module is exposed to strong direct sunlight.	Ensure that the rear of module is not directly exposed to strong sunlight. Contact Moyo Scientific Service.
Cover violation	The top foam was removed during operation. Foam not activating the sensor.	Replace the top foam. Exchange the foam.
