arrangement of temperature sensors is
required. The Platinum Plus lists the
growing zones in Install | Temperature
Definition so you can assign specific
sensors. Later when expanding the growth
area, select Control | Control Mode and
change from one to another. If you wish to
change complete fan setups and other
equipment in addition to sensor assignments,
you may obtain the optional Gold Plug
which stores up to 8 complete programs.
10. Minimum Vent (Power)
: Minimum Vent
(Power) refers to cross ventilation using
exhaust fans and side air inlets. In general it
covers everything that is not Natural
(conventional) or Tunnel ventilation. Most
buildings use two ventilation modes, Min
Vent and Tunnel, although some use only
Natural Ventilation. Select whether
Minimum Ventilation applies.
11. Natural Ventilation
: Natural ventilation
refers to providing fresh air for the birds or
livestock using large curtain sided buildings
in which the curtains open and close by
controller command. Typically, the building
structure will have curtains along two long
sides which open to allow natural air to flow
across through the building in one side and
out the other. The majority of today’s
facilities do not use this method. Select
whether Natural Ventilation applies. Some
buildings using natural ventilation only,
without fans. In Standard mode, if you
disable Min Vent (Power), enable Natural
ventilation, and have no fans assigned the
Min Vent timer, Standard mode supports
minimum ventilation using the curtains to
purge the house periodically.
12. Tunnel
: Tunnel ventilation refers to
ventilation in long, relatively narrow
buildings in which fresh air enters at one
end, travels through the length of the
building and exhausts at the other end. The
object is to remove heat and provide cooling
by the wind chill of air flow past the birds or
livestock. In this method, the air picks up
heat as it travels through the building so that
there is some temperature rise from the inlet
end to the exhaust end. The rise must be
limited to reasonable values by ensuring a
minimum air flow rate. Typical minimum
air flow rates will enforce a two minute
travel time for the air from the inlet end to
the exhaust end at initial tunnel ventilation,
and perhaps one minute at maximum levels
of tunnel ventilation. Select whether tunnel
ventilation applies to your facility.
13. History Resolution
: The Platinum Plus
collects a large amount of historical and
management data. History Resolution
provides resolution choices from daily to
minute by minute. This applies to the
detailed History View submenu under the
History menu. Select the particular data to
collect in the History View menu itself
under its Help | Set parameters.
Relay Layout
1. Assign functions to the relay outputs and
control switches. To assign a function, move
the cursor to the relevant relay under the
function column and press the Enter key. A
pop-up appears listing possible choices.
Scroll to the desired function and press
enter.
a. You can assign most functions such as
Heaters and Fans only once. If you
attempt to assign ’01 Heat 1’ to relay 23
when it is already assigned elsewhere
such as to relay 5, the controller will
reject the new assignment. To move a
function, delete the first instance and
then assign it in the new location.
b. Some functions, such as feed and lights,
can be assigned multiple times.
c. To duplicate functions
that you can not
assign more than once, use the ‘as relay
#’ codes which start at number 123.
Any relay with one of these codes
serves the same function as the
referenced relay. For example, if relay 5
is Heat 1 and you want a duplicate Heat
1 on relay 15 for some reason, assign
‘127 as relay # 5’ to relay 15.
d. Inlet open/close and curtain functions
can each be assigned only once and can
be duplicated using the ‘as relay# codes.
In the case of inlet functions, turning off
the reference relay causes the duplicate
functions to not operate correctly. If you
need to have inlets or curtain functions
