5.3. DIPSWITCH SETTINGS
To program the operation of the automation, set the dipswitches
as shown in the diagram above.
Ü
Press the RESET button after all programming operations.
(1) With the pre-flashing selected, movement starts after 5 seconds.
(2) If the impulse is sent during pre-flashing, the timer is reset to zero.
5.4. FAULT CONDITIONS
The following conditions effect normal operation of the
automation:
a
microprocessor error
b
intervention of the electronic safety timer (interruption of
operation after continuous working time exceeds 255
seconds).
c
disconnection of the limit switch cable connector
• Conditions
a
and
b
have the sole effect of causing the
automation to stop.
• Condition
c
causes an alarm condition inhibiting all
operation:
normal operation is only resumed after the cause of
the alarm has been eliminated and the RESET button
has been pressed (or the power supply has been
momentarily interrupted).
To signal this condition, the warning light must be connected:
an alarm condition is signalled by rapid flashing (0.25 sec) of
the warning light.
5.5. POSITIONING THE TRAVEL STOP PLATE
The 746 operator is fitted with an inductive proximity limit switch
(Fig.1 - ref.3). When the latter detects the passage of a plate
fastened to the top of the rack, it stops the movement of the
gate.
To position the two travel stop plates correctly, proceed as
follows:
1)
Connect the limit switch connector to the 746MPS control
unit in accordance with the direction of gate closure
(paragraph 5.2.3. and Figs. 28/29).
2) Assemble the limit switch, positioning the stop plate cen-
trally relative to the threaded studs of the bracket (Fig.32).
3) Switch on the power supply.
4) Move the gate by hand towards it closed position, stop-
ping approximately 2 cm from the physical travel stop.
5) Set brake-adjusting trimmer TR1 approximately to its cen-
tral position (Fig.23 - ref.TR1).
TABLE 5 LOGIC A1 (AUTOMATIC)
Operating logics
There are four operating logics available:
A1 = Automatic A2 = Automatic Plus
E1 = Semi-automatic E2 = Semi-automatic Plus
Operation of the different logics is described in tables 5-6-7-8.
Pause time
The pause time is amount of time the gate remains open
before it recloses when an automatic control logic is selected.
Pause times include the pre-flashing time, if selected.
Pre-flashing
It is possible to select 5 seconds pre-flashing of the flashing light
before any gate movement. This serves to warn any persons in
the vicinity that the gate is about to start moving.
