Operation - Auto Re-Engage
Note: Auto Re-Engage requires an iDock Control
System. Units without an iDock Control System do
not have this functionality.
After restraint has been engaged with successful
capture of RIG bar, these restraints will automatically
attempt to re-engage if they leave the working zone:
• When restraint hook is lowered to the stored
position without pressing the RELEASE button,
the controls will automatically attempt to re-
engage the hook one (1) time.
• If hook successfully captures the RIG bar
again, the light communication will remain the
same.
• If hook is unable to return to the working
zone after one (1) attempt, the hook will
automatically return to the stored position,
and the iDock Control System will alert
the operator that the restraint is no longer
engaged with a Bypass Mode prompt. See
“Operation - Unsuccessful Engage.
