The Fast Transfer and Synchronous Transfer window timers are set as follows:
a) Fast Transfer Window Timer - 0.17 second (fixed).
b) Synchronous Transfer Window Timer - 0.1 to 2 seconds (adjustable).
Fast T.,nsfpr Control - The Fast Transfer Control will compare the phase information from the PTR with the limit set on the PHASE ANGLE LIMIT control and issue a close command when the phase is inside the phase angle limit.
The PHASE ANGLE LIMIT control is adjustaole from 0 to 45°.
Synchronous Transf°' Control - The Synchronous Transfer Control issues an activate input signal to the PTR during the synchronous transfer time window. This enables the PTR to close the breaker, using the In Phase Transfer technique.
Residual Volt-age Control - The Residual Voltage Control is enabled by the sequencer. The Residual Voltage Control compares the bus voltage to a preset lower limit and issues a close command when the bus voltage drops below the voltage limit.
