ABB SYN520 series synchronous device SYN5202-0277 SYN 5202-0277

The design of the SYN 5202 guarantees a degree of security against incorrect paralleling which satisfies the most demanding requirements, because the different processor types in the individual channels are equipped with different software and completely separate measuring units and command relays. The program sequence is interrupted and reset by the internal watchdog, if an error occurs. After reset, it is again started automatically. This starting procedure is carried out three times, afterwards the device is totally blocked with the corresponding error message.

After expiry of the set total paralleling time tot t, the monitoring of external events indicates failure by the control system or measuring signals to fulfil conditions, as well as implausible configuration. If necessary, t tot can be set to zero. This deactivates this monitoring function.
