Re-syncing Multiple Sequencers

There can be unique situations where multiple sequencers fall out of 
sync. For example, loss of sync can occur when a branch circuit experi-
ences an overload or high voltage and triggers an EVS shutdown of one 
or more units. If you are using a rack mounted Contractor unit equipped 
with SmartSequencing, you can re-establish sync by pressing and holding 
the Start Sequence pushbutton on the Primary Unit for several seconds.  
Sync can also be re-established by rotating the key on the primary unit 
from the REMOTE to the OFF position and then back to REMOTE.  When 
pressing and holding the pushbutton on dedicated SmartSequencing 
units, the Primary Unit commands the Secondary Units to “Go Home” 
and all units will sequence down in reverse order. Once the chain of 
sequencers has cycled off, the sequencers can be sequenced on again 
by pressing the START SEQUENCE button or turning the key switch to the 
ON position.

Legacy connected sequencers can also be re-synced if the sequencers 
are operating Momentary Mode.  The units will resync can be accom-
plished by pressing and holding the Start Sequence pushbutton.  Unlike 
the SmartSequencing chains, units will cycle down, yet may not cycle 
down in hierarchical order.  It is advised that all sound sources be muted 
before a re-sync action is initiated. Once the re-sync is initiated, unit will 
cycle down and return to an off state.  A sequence can now be “ramped 
up” in order.
