1. (B) Pressure Reverse Switch
This option stops the gate overcrowding the cows. As the gate moves forward and starts to lift
on the back of the cows, it hits a micro switch and stops the gate moving forward and
reverses for 3 seconds. This feature is fitted to all gates.
Note: that the pressure reverse switch only works when the gate is fully down it also operates
in the “Cycle” and “Syncro” programs.
1. (C) Down Delay
During the down travel in either an option or using the down push button. The gate will travel
down for 7.5 seconds, stop for 3 seconds for cows to part in the yard, then continue to travel
down. This feature is designed to capture half the cows in the yard.
Note: the down delay will only operate if the down operation commences from the gate upper
limit and will operate in every mode except in wash mode.
1. (D) Pull Switch, Forward Motion
The pull switch is to stop or start the backing gate. Activation of the pull switch will not reset
the “Syncro” or “Cycle” program but will allow the gate to move forward.
Note: 2. Forward motion can also be controlled by pull switch when the gate is in one of the
optional pulse or cycle programs.
1. (E) Gate Brake, DC Hold Program
The gate has a special program embedded within the gate to lock the shaft of the motor after
travel has completed this feature will stop the gate from rolling back down the yard on sloping
yards and if the gate is stopped during the down travel.
Motor over run can some times be a problem on larger wider gates because of the inertia and
weight of the gate so this feature will also stop that from happening.
Note: at the end of any movement the gate brake will operate for 3 seconds and no button
can be pressed in that time to commence operation to give the gate time to brake.
1. (F) Reverse Down Safety
This program has a special timer to stop the gate from travelling backward to far while the
gate is down to avoid a second herd in the yard behind from getting crushed and will limit the
gate from travelling back for six seconds this can be over ridden by holding down the reverse
button for one second The gate will emit a beep to indicate the reverse safety has been
overridden.
1. (G) Off Limit Safety Timer
This program has a special timer to stop the gate if it takes more than 5 seconds to get off the
safety limit in case something goes wrong or the gate is stalled or jammed. The gate will
alarm indicating that a fault has occurred by emitting 3 short tones and gap being either the
down siren or the forward siren to indicate the directional limit at fault.
1. (H) Opposing Limit Safety Timer
This program has a special timer to stop the gate if it takes more than 300 seconds (or 600
seconds during wash) to get to the apposing for/rev limit or if it takes more than 25 seconds to
get to the apposing up/down limit.
This program is designed in case something goes wrong or the gate is stalled or jammed. The
gate will alarm indicating that a fault has occurred by emitting 3 short tones and gap being
either the down siren or the forward siren to indicate the directional limit at fault.
1. (I) Bypass mode
This program has a Bypass mode if one of the limit switches should fail to enable the gate to
temporally operate, to enter this mode press in the stop button and turn on the main gate
controller until the siren sounds a one second pulse.
In this mode you can press the direction buttons and the gate will only move for as long as
you hold the buttons down and it will ignore the limit switch so be careful.
NOTE: the optional programs will not operate in this mode as it is assumed the limit or limit
switches are faulty which may cause undesired operation of the gate.
Bypass mode will have a maximum run time of 10 seconds as a safety per button operation.
