Operation
With the 3
-
Position Switch (fig. 10.f) a choice can be made to open the L
’
port closing
gate (Open), to close the L
’
port closing gate (Close) or to have the L
’
port closing gate
operate automatically (Auto). In position
‘
Automatically
’,
the L
’
port closing gate will
close when the feed motor receives an electrical pulse. The L
’
port closing gate will open
after a delay time. The delay time will automatically reset when the feed motor has re-
ceived a new electrical pulse. This delay time can be set via the 14
-
positions switch on
the L
’
port Control PCB (time setting in sec.) (fig. 9). The delay time has to be bigger than
the total interval time of the used feed kinds. Recommendation: interval time + 25 sec-
onds.
Meaning
With the brands of DeLaval, Fullwood, Insentec, Hokofarm and GM time
has to be set at 40 seconds (pos. 4). With Nedap VC control: add the inter-
val time of the used feed kinds + 25 seconds. So, with one feed kind 40
seconds (pos. 4), with two feed kinds 60 seconds (pos. 6) etc. A spray in-
stallation to be connected on the
‘
Spray
’
output is optional.

Adjustment
1.
Adjust the length of the cylinder
-
rod to the fork (fig. 10.c) so that it puts pressure
on the anti
-
jump gate in the lowest position.
2.
With the
‘
Speed in
’
adjusting possibility, that is indicated on the lid with
‘
Speed
in
’
(fig. 10.g), it is possible to set the ingoing speed of the cylinder
-
rod. Be sure
that the L
’
port moves in ±3 sec, from bottom to top position.
3.
With the
‘
Speed out
’
adjusting possibility, that is indicated on the lid with
‘
Speed
out
’
(fig. 10.e), it is possible to set the outgoing speed of the cylinder
-
rod which
has to be ±5 sec.
4.
With the
‘
Cushioning
’
adjusting possibility, indicated on the lid with
‘
Cushioning
’
(fig. 10.h & i), the end cushioning can be set to a fluent end stop of
the rod. The adjust tool is 2.5 mm hexagon socket.
Please note! When the above adjustment steps are not observed correctly, this
may reduce the durability of the L
’
port Closing gate drastically.
Danger! Check whether the air lines are properly connected and that they are
not pinched before pressure is placed on the lines. In the event of incorrect
connection, the output force of the cylinder can be increased, resulting in
serious pinching hazard.
Start
-
up
After installation: Leave the L
’
port closing gate open for one week by putting the switch
on
‘
Open
’
(fig. 10.f), so that the cows can get used to the new installation. After this
week the installation can be put into operation, by placing the switch (fig. 10.f.) to
‘
Auto
’.
The sound level always equals 70 dB (A) or less.
Caution
Attention! Danger of
getting jammed.
Attention! L
’
port closing gate
