BECKHOFF EP20xx/EP28xx Output Module Installation and Debugging Guide

Output is non-conductive (LED not lit), output is not enabled or Up power supply is missing. Check the Up voltage (24V) and GNDp connection; Confirm that the process data output bit is TRUE

The output light is on but the load does not operate. If the power supply is insufficient or the line voltage drop is too large, measure the voltage at the load end; Check the length and cross-sectional area of the cable; Calculate whether the total current exceeds the limit

Check the load connection if the output circuit of the diagnostic bit "Open load" is open or the load current is less than the detection threshold; For EP2038/2839, the threshold is approximately 1mA to ensure sufficient load current

The output terminal of the diagnostic bit "Short to 24V" accidentally contacts the 24V power supply. Check if there is a short circuit in the external wiring; If there is a false alarm, the diagnostic bit can be disabled

After communication interruption, the output did not close as expected. Safe state was not activated or the safety value was set incorrectly. Check the Safe state active and Safe state value settings in the CoE

After a short circuit, all outputs are turned off and cannot be restored. F800:01=False and Reset outputs have not been executed. Recovery is achieved by setting the process data "Reset outputs" (rising edge); Or change to TRUE to achieve automatic recovery

The total current of the module overheating alarm exceeds the rated value or the load current is reduced due to high ambient temperature; Strengthen heat dissipation; Check if it exceeds the upper limit of 60 ° C (ATEX is 55 ° C)

The installation of BG2000 protective cover in ATEX area has been rejected or the protective cover has been installed due to temperature exceeding; Ensure that the ambient temperature is between 0 and 55 ° C; all interfaces are sealed

LED Us/UP display red (EP2038-0042) undervoltage or auxiliary output overload check if the power supply voltage is less than 18V; check if the auxiliary output exceeds 0.5A

Maintenance and scrapping

Cleaning: Use only a vacuum cleaner or a slightly damp cloth to clean the casing. Do not use compressed air to prevent dust from entering the interior of the connector.

Sealing inspection: Regularly check the fastening status of all protective covers and cable joints to ensure IP67 protection.

Scrap: Dispose of according to the WEEE directive, the metal casing can be recycled, and the circuit board is disposed of as electronic waste.
