tSlaveDeadTime: When activating the WAIT input, in the auto recloser set as slave,
every dead timer is changed to the value of setting tSlaveDeadTime and holds back
the auto reclosing operation. When the WAIT input is reset at the time of a
successful reclosing of the first circuit breaker, the slave is released to continue the
auto reclosing sequence after the set tSlaveDeadTime. The reason for shortening
the time, for the normal dead timers with the value of tSlaveDeadTime, is to give
the slave permission to react almost immediately when the WAIT input resets. The
minimum settable time for tSlaveDeadTime is 0.1sec because both master and slave
should not send the circuit breaker closing command at the same time.

15.3.1 Application
M13443-4 v14
The apparatus control is a functionality for control and supervising of circuit
breakers, disconnectors, and earthing switches within a bay. Permission to operate
is given after evaluation of conditions from other functions such as interlocking,
synchrocheck, operator place selection and external or internal blockings.
The complete apparatus control function is not included in this
product, and the information below is included for understanding of
the principle for the use of QCBAY, LOCREM, LOCREMCTRL,
SCILO, SCSWI, SXCBR.
Figure 312 shows from which places the apparatus control function receives
commands. The commands to an apparatus can be initiated from the Control
Centre (CC), the station HMI or the local HMI on the IED front.
