- precision of slowdown area
- possibility of operation (without detection of obstacles) also with motors without encoder
Installation and testing of installations with encoder
Connect the motor encoder to the 3-pin connector located near the trimmer PW; the control unit automa-
tically detects the connection and makes the LED L1 blink during programming. If the LED does not blink,
the control unit works with timed parameters (as in previous models).
Adjusting the motor power
EN 12445 requires that every automation system must pass impact tests measured with a special instru-
ment. Carry out the impact tests and change the motor torque through the trimmer PW (part 3 of fig. 1).
If adjustments are insufficient to make values fall within the graph indicated by the above standard, we
recommend installing a soft rubber profile on the leading edge of the gate in order to soften impact.
If the requirements of the standard can still not be met after having adjusted the motor torque and mounted
the rubber profile, alternative devices must be mounted, such as a safety edge on the leading edge of the
gate.
2) CLOSING AFTER PHOTOCELL ACTIVATION FUNCTION
Upon enabling this function the control unit reduces the pause time to 2 seconds after photocell activation
(FT1).
Procedure to enable the photocell function:
- cut off the power supply to the control unit;
- reconnect to the power supply while keeping the Stop/Prog button pressed;
- after 3 seconds LED L1 lights up
- keeping the Stop/Prog button pressed, press for a brief moment the P/P button;
- LED L1 starts to blink;
- still keeping the Stop/Prog button pressed, press the P/P button. The LED changes blinking rhythm each
time the P/P button is pressed;
- fast blinking means that the closing after photocell activation function is enabled;
- slow blinking means that the function is disabled;
- after having made the selection, release the Stop/Prog button; the control unit makes the appropriate
storage and starts up normal operation.
3) OPEN GATE INDICATOR LIGHT
In the previous models the terminal 12-13 output could control both the indicator light and the foto-test,
maintaining the same operation. The indicator light came on at the start of a cycle and went out when the
gate was fully closed.
If the installation was not set up for the foto-test, it was necessary to put dipswitch 7 to OFF.
The new control units offer a double possibility:
installations without foto-test (dipswitch 7 Off)
The terminal 12-13 output acts as gate status indicator light
- during opening it blinks slowly
- during closing it blinks fast
- during pause time (waiting to close again), double blinking with pause of 1 second
- in situation of permanent stop (stop, safety edge or anti-crushing device activation), fixed light
installations with foto-test (dipswitch 7 On)
Connect the power supply of the photocell transmitters to the output 12-13. It is possible to parallel an
indicator light with simplified operation (previous models).
CAUTION: if the foto-test is not used, do NOT connect the photocell transmitters to the output 12-13.
If a previous version of control unit is to be replaced, pay attention to the photocell connection and
check that it is in compliance with the above instructions.
