Important Product Information for Release 1.01

New Features and Enhancements

With this release, the PSM accounts for the breaker delay, and the rate of change of the phase shift between the grids, to time
the CloseRelayOK status and ACC200 relay outputs to close the sync relay contacts when the phase shift between the grids is
0⁰.
This release also adds the special case of Breaker Delay = 0. When the ANSI 25 Breaker Delay parameter is set to 0, the
PSM turns off breaker delay calculations and operates in Classic sync relay mode. In Classic mode, the PSM sets the
CloseRelayOK status and the ACC200 relay outputs to On whenever the application requests a sync and the phase shift
between the grids is in the range –Phase Shift Threshold to +Phase Shift Threshold.

Note: The PSM module is not compatible with IC695CPE305 and C695CPE310
firmware version 7.30.
CPU firmware version 7.70 or newer support the IC694PSM001 module on these
CPU types:
IC695CPE305

COM1 and COM2 of the IC694ACC200 must be connected to functional ground
(Earth ground).
COM1 and COM2 must not be connected to Neutral in a WYE power system.
In certain fault conditions, Neutral can be pulled to the full voltage of any phase. Such
a fault condition can pose a danger to personnel and damage the IC694ACC200. See
GFK-2749 for wiring diagrams.
