Section 13
Control
that this have a considerable delay. Input can also be used for other purposes if for some reason
the Auto-Reclose shot need to be halted.
TR2P and TR3P
Signals for two-pole and three-pole trip. They are usually connected to the corresponding output
of the TRIP block. They control the choice of dead time and the reclosing cycle according to the
selected program. Signal TR2P needs to be connected only if the trip has been selected to give
1/2/3 pole trip and an auto reclosing cycle with two phase reclosing is foreseen.
WAIT
Used to hold back reclosing of the "low priority unit" during sequential reclosing. See
"Recommendation for multi-breaker arrangement" below. The signal is activated from output
WFMASTER on the second breaker Auto-Recloser in multi-breaker arrangements.
BLKON
Used to block the autorecloser for 3-phase operation (SMBRREC ,79) function for example, when
certain special service conditions arise. When used, blocking must be reset with BLOCKOFF.
BLOCKOFF
Used to Unblock SMBRREC (79) function when it has gone to Block due to activating input BLKON
or by an unsuccessful Auto-Reclose attempt if the setting
RESET
Used to Reset SMBRREC (79) to start condition. Possible Thermal overload Hold will be reset.
Positions, setting On-Off. will be started and checked with set times.
Recommendations for output signals
Please see figure 114, figure
