4.5. Feed Delivery Process
After the Chain Disk Systems have been
filled up, feed is ready to be delivered to
the animals. This section explains how feed
is dumped by actuators and air valves and
how it is being delivered when no actuator/
air valve is used. Note that the actuators and
air valves can only be used with the timer-
based feed distribution mode and note that
their parameters are common to all Chain Disk
Systems in use.
Feed Delivery using Actuators:
1. The actuator opens the drops during the
opening time.
2. When the opening time has elapsed, the
actuator stops moving during the “A c t u a t o r /A .
Valve Delay”;
3. When the “Actuator/A.Valve Delay” has
elapsed, the actuator fully closes the drops
during twice the opening time or until its
security switch is reached.
4. End of the feed cycle.
Feed Delivery with Air Valves:
1. The air valve make the dumps open at the
“Dump Time”;
2. The dumps remain opened during the
“Actuator/A.Valve Delay”;
3. The air valve make the dumps close after
the “Actuator/A.Valve Delay” has elapsed.
4. End of the feed cycle.
Feed Delivery without Actuators &
Valves:
If no actuator or air valve is used, all feed that
enters into Chain Disk Systems directly falls
in the feeders while the Chain Disk Systems
are being filled. When they are full, the feed
gradually decreases in the feeders as the
animals eat.
4.6. Feed Cycle
When the feed distribution is done in timer
mode, the user must specify the moment at
which the Chain Disk Systems must be filled
and the time at which feed must be delivered
to the animals. Up to 25 feed cycles can be
performed each day. Refer to section 5.6 to
enable the required number of cycles.
Feed Cycle Start Time:
This is the time at which each feed cycle
starts.
The controller automatically adjusts
the time at which the feed cycles
start and the number of feed cycles
in case of a programming error (i.e. if
the feed cycles overlap one another
or if they exceed 24 hours).
Dump Time:
If actuators or air valves are used, set the
time at which the dumps must open. Make
sure this dump is performed when all the
Chain Disk Systems are full. The dump time
should be higher than the “Start time + Max
Run Time” of all Chain Disk Systems otherwise
the controller will automatically redefine this
time setting.
Run Time:
If no proximity sensor is used, a run time must
be defined. This value represents the amount
of time that is required to fill-up each Chain
Disk System.
