TEST MODE
In test mode, a functional test is performed on the controller. This test examines the internal programs of the microprocessor and any
peripherals connected to it.
In particular: - the control leds confi rm external connection to the controller
- the status leds confi rm the internal conditions of the controller
Procedure: Set DIP switches 1, 2 , 3 OFF and press reset.
# Check: All control leds should fl ash simultaneously, except for those for NC contacts (that remain lit), and the REV and RES leds,
that remain switched off.
The status LEDs should light in sequence.
Test: Check that as you trimmer TM1 (PAUSE) the fl ashing frequency of the control LEDS varies and the status LED sequence
changes speed. This shows that the microprocessor is functioning correctly.
If Status relay fails to operate, the controller is probably faulty.
Failure of one or more status leds to illuminate indicates a controller fault.
Failure of one of the control leds to illuminate indicates a fault in the connection to the corresponding external unit.
MANUAL MODE
In manual mode, hold down the Opening and Closing button to operate the barrier.
When you hold the Open button down, the barrier lifts, and the motor stops when the barrier reaches the end of its travel.
When you hold the Close button down, the barrier lowers, and the motor stops when the barrier reaches the end of its travel.
The photocell is engaged in both opening and closing phases; to resume normal operation, release the interrupted command and repeat.
Dip switches 3, 4 , and 5, Operation Timer, RX1 and Serial are inhibited.
The reverser operates as programmed, unless DIP switches 7 and 8 are ON, in this case it stops the barrier and re-opens as far as
FCA, and commands are re-enabled only after the Stop button is pressed.
SEMIAUTOMATIC MODE
The barrier is operated by pressing without holding the Start, Open, and Close buttons.
The duration of pressing won' t be longes than operating time.Commands generate complete opening or closing cycles.
DIP switch 3 controls press and release closure.
AUTOMATIC MODE
The barrier is operated by pressing without holding the Start, Open, and Close buttons.
The duration of pressing won' t be longes than operating time.
In the opening phase, once the barrier reaches travel stop (FCA), it waits for an interval, set by means of trimmer TM1, and then proceeds
automatically with closure.
PRESS AND RELEASE CLOSURE
This mode is designed for automatic closure of the barrier only when the vehicle has crossed the photocell or magnetic detector (acces-
sories most suitable for this system).
Connect the NO contact of the detector or photocell to terminals 8-10 (Close contact) and set dip switch 3 to ON.
The presence of a vehicle over the detector or in front of the photocell does not cause immediate closure; this only occurs following the
relative signal.
Stop command fault (NC)
The STP led under normal conditions remains permanently lit. If it switches off, this indicates that the Close contact has opened due to
an error in operation. No command is operative until this contact is reset to NC.
Open (NO), Close (NO), Start (NO) command faults
The OPN, CLS, and RUN leds remain off under normal conditions. If one of these should short circuit, the respective led illuminates and
the other commands are no longer operative. Reset to NO to resume normal operation.
