Operation
2.5.1.
Single-phase logic
The logic unit includes the board AS1200,
with
relays REL 3 (
1:22
) and REL 4 (
1:23
) as well as the
fuse F2 (
1:19
).
A capacitor is required on outputs U and V of X2 (
1:2
) in case of standard three-phase motor.
2.5.2.
Three-phase logic
The logic unit includes the board AS1200
without
relays REL 3 and REL 4 and the fuse F2, but the
AS1206 board has been placed.
In this case, the motor used will always be in three-phase.
2.5.3.
Hierarchy of the commands
The obstacle commands are organised following this hierarchy:
1)
Stop
2)
Blocked-open
3)
Blocked-closed
4)
Opening
5)
Closing
This means that the "Stop" command will have priority over all the others and that "Blocked-closed"
will have priority over "Opening" and "Closing".
Note:
the opening and closing commands proceeding from the presence sensors are
always at points 4 and 5.
2.5.4.
Decommissioning (HS)
The barrier will be out-of-order whenever a limit switch is not reached by the end of the movement
time-out programmed in parameter 1.
2.5.5.
The sensors
The sensors are the principal peripherals of a barrier. They may be presence detectors using an
induction loop, photoelectric cells, radars, etc.
In all cases, conventional name for the sensors is: “DP”.
2.5.5.1. Sensor boards
Three types of boards manage the information given by the sensors.
1.
DP 139
Management board for one magnetic loop.
2.
DP 239
Management board for two magnetic loops.
3.
AS 1225
Reception board of one or two dry contacts from external sensors as detectors,
photocells, keys, radio command, etc
These boards are plugged on connectors X3 and X4 of the board AS1200 and must be located.
This location is called the I²C address of the board.
The LOW address defines the board for sensors 1 and 2 (DP1 and DP2)
The HIGH address defines the board for sensors 3 and 4 (DP3 and DP4).
This address is essential for all functions of the sensors in the programming.
The following table indicates the various address for each sensor.
