Anti-Recycle
Anti-Recycle defi nes the method of motor protection
due to repeated motor starts. The operator has 3 choices
of protection. Hot starts allows only a certain number of
starts per hour before setting an hour to the anti-recy-
cle timer. The number of starts is set in the timer page.
Accumulative immediately adds time to the anti-recycle
timer once the compressor is started and the time can
be set in the timers screen. True anti-recycle adds to the
anti-recycle timer once the compressor is shutdown. The
motor of the compressor can not be restarted as long as
there is anti-recycle time left and the operator can view
this time on the top left corner of the main screen.
Restart On Power Failure
This feature of the Vission 20/20 offers the ability to de-
fi ne how the Vission 20/20 will handle a power failure.
This can also be useful to allow system controller to re-
gain control of the Vission panel without the need for
operator intervention.
Always:
• When selected, initiates a start after the panel pow-
ers back up after a power failure, but only if the com-
pressor was running before the power failure and
starts the compressor in Auto mode.
Never:
• When selected, prevents any automatic action once
the panel powers back up after a power failure.
Timed:
• When selected, initiates a start after the panel pow-
ers back up after a power failure and the operator set
timer runs out. When there are multiple compressor
in a larger system, it is recommended that the opera-
tor gives each compressor a different start times. A
restart will only occur if the compressor was running
before the power failure and starts the compressor in
Auto mode.
Remote Lock Off:
• When selected, turns the remote lock out off when
the panel powers up. Select this option if the opera-
tor wishes a system controller to regain control of the
Vission 20/20 without human interference.
Boot in Remote (Direct I/O)
• When selected, places the panel into remote mode
when the panel powers up. Select this option when
under direct I/O control and the system controller is
to gain control of the Vission 20/20 without human
interference.
