HEATING CONTROLS
Maximum 2 independent ventilation controls can be installed.
Heating controls
On/off switching heating (relay)
Proportional: 0-10V (eventual in combination with a relay output)
COOLING
Maximum 1 independent cooling can be installed. If an RH sensor is used, the cooling can be switched off when
the relative humidity has become too high.
Cooling controls
On/off switching cooling (relay)
Time proportional control (relay)
Proportional (0-10V)
HUMIDIFICATION
Maximum 1 independent humidification control can be installed. Since cooling and humidification complement
each other, cooling can be connected to the same relay output as humidification.
TIMERS
Maximum 6 timers can be installed. A timer can be combined with a counter input to dose water, feed etc.,
using the timer. Maximum 3 timers, for dosage (feed/water) and/or for light control, can be installed. If the
timer is assigned to a 0-10V input, it can be used to create a light control (maximum 1 light control).
COUNTERS
Maximum 2 counters can be installed. The first 6 counter inputs may be combined with a timer for dosing.
I/O MODULES AND FN DEVICES
I/O module
:
You can use I/O modules to extend the number of outputs of the PL-9000 poultry computer, via
the ST bus (module bus). The control computer indicates which output must be driven by the PL-9000 poultry
computer.
The poultry computer has a memory chip where all settings are saved into, to ensure that the settings are
retained even when the voltage is lost.
Counter positions, burning hours, current day number in the curve etc. are not stored in the memory chip.
These values may be lost if the power supply to the poultry computer has been down for a couple of days. You
may then have to set the day number etc. again.
