Maintenance and spare parts recommendations

Considering that M-3311 is an early model that has now been replaced by M-3311A, it is important to note during on-site operation that:

If replacement is required, refer to the compatibility of M-3311A, but confirm the differences in CT quantity, voltage input channels, and winding number (M-3311A supports four windings and more voltages).

Regularly download waveform and event records through IPScom software, as data loss occurs after the device loses power (oscillation waveform and event records are stored in RAM).

Check that only dry contacts are allowed on the input terminals to avoid damage caused by accidental connection to external power sources.

For external logic such as temperature controller monitoring, it is necessary to regularly verify the correctness of the BECO Logic program.
