CURRENT SENSING ADJUSTMENTS
Because gates vary in construction and may have different force requirements in the open and close directions to move, the OSCO control board has separate
Prior to adjusting the operator current sensing functions, make sure the gate moves freely in both directions. A badly aligned or poorly maintained gate may cause false triggering of the current sensor. Refer to page 9 when following the instructions below. A factory adjustment tool has been supplied to make these adjustments easier. This tool has been taped to the control box for your convenience.
CLOSE DIRECTION CURRENT SENSE ADJUSTMENT
When the gate operator leaves the factory, it has been preset for a relatively light gate function and will require additional adjustment. Begin by starting the gate going closed. If the operator stops and reverses, turn the close direction potentiometer (see page 9) one turn higher, press the STOP button, and try again. Repeat this process until the gate no longer causes false tripping of the current sensor. Note that each time the gate operator reverses, the STOP button must be pressed. Next, turn the close direction potentiometer lower slowly while the operator is running the gate closed until the gate operator stops and reverses again. From this point, turn the close direction potentiometer higher by 1 1/2 turns for all 115 Volt AC and 24 Volt DC operators, and by 3/4 of a turn higher for all 230 Volt AC operators. Additional fine adjustment by 1/4 turns may be necessary to eliminate false triggering.
OPEN DIRECTION CURRENT SENSE ADJUSTMENT
Repeat the same process with the open direction potentiometer while running the gate in the open direction. Once this is done, run the gate through several complete cycles and make sure the gate does not false trip in either direction.
Multi-turn Potentiometer
Remember it is important not to set the adjustment too high! Doing so will defeat the purpose of the cur- rent sensing as an obstruction detecting feature.
MAXIMUM RUN TIMER ADJUSTMENT
This adjustable potentiometer sets the maximum length of time the motor will run before shutting down. It should be configured for the time it takes to run the gate fully open or closed, plus an additional 15 seconds. See page 9 for details.
BATTERY
FOR DC MODELS ONLY
CHARGER BOARD CONFIGURATION
To set the voltage monitor, see the picture below. The RUN posi- tion will monitor the voltage of the battery only after AC voltage has been interrupted. It will allow the operator to continue to function until the batteries have dropped to 17 volts. When the batteries have reached 17 volts, the operator will open and shut down until AC power has been restored. In the OPEN ONLY position when AC power has been interrupted the operator will open and shut down until AC power is restored.
Note: If the charger board is set to open only, removing incoming power will cause the operator to run to full open position. Turn off power switch in operator before removing incoming power!
AUTO CLOSE TIMER ADJUSTMENT
This adjustable potentiometer sets the length of time which elapses before the gate operator automatically closes the gate, from the fully open position, provided no open, reversing, or obstruction signals are present. This feature can be turned on or off via dip switch selection. See page 9 for details. Do not use the auto close timer without an appropriate reversing device installed!
