Professional setup

Professional setup is a semi-automated procedure, similar to Easy Setup, but with the
following differences:
Initiate by pressing P2/RADIO instead of P1/SET
The installer must intervene to manually operate the gate
The installer may set a desired slow-down position, if not there will be no slow-
down
The installer must intervene to manually close the gate
The installer may change the behaviour in response to photocells
If pedestrian opening is required, then the installer must set it, otherwise pedestrian
opening time is zero
NOTE This procedure sets the gate travel time based on the detection of the limits of
travel. Limit actuating plates must be fitted to the rack.
CAUTION During this procedure the gate must be attended. The gate must be in the
midway position before starting this procedure.
To initiate the procedure, press P1/SET, then while the yellow LED is flashing, press P2/
RADIO again for 1 second.
NOTE It may be more convenient to use a transmitter to control the process, than to press
the P1/SET and P2/RADIO buttons on the controller board. If so, learn one button for P1
(learn the button with the CH-RADIO jumper removed), and one button for P2 (learn the
button with the CH-RADIO jumper fitted).
The following steps are performed automatically:
1.
Checks for presence of a motor; photocells (or a jumper) on PHO terminal; e-stop
(or a jumper) on STP terminal.
2.
Begins to open the gate, with a force set by the FOR trimmer.
NOTE If the gate begins to close first, switch off the power to stop the movement
and then reverse the motor wiring accordingly. Start this setup procedure again.
3.
After 3 seconds of opening, gate stops moving.
4.
Closes the gate fully, stopping using the closed limit switch.
The following steps must be performed by the installer:
5.
Press either P1/SET or P2/RADIO to begin opening the gate
6.
Press P1/SET at the time where M1 slow down to 1/3 speed is required
7.
The gate will continue to open fully, stopping using the open limit switch.
The following steps alter the response to interruptions of any photocells. Step 11 makes
no change, Step 12 selects the 'stop when interrupted, move when clear' option:
8.
Only press P1/SET to close the gates if:
a. photocell is obstructed when closing then reverse immediately, and;
b. photocell is obstructed when opening do nothing
9.
Only press P2/RADIO to close the gates if:
a. photocell is obstructed when closing then stop and only reverse when obstruction
is removed, and;
b. photocell is obstructed when opening then stop and continue opening when
