7 - TESTING AND COMMISSIONING
Once the programming setup has been completed, verify that:
• the motors turn off after a few seconds once the opening or
closing phases end (also "error" LED turns off);
• the control unit responds to the connected wired commands:
"START" (terminal 7), and "STOP" (terminal 6);
• all programmed radio transmitters are operational;
• the safety devices connected to "S2 Photo" (terminal 4)
intervene while the door closes and prevent the open door
from closing;
• the safety devices connected to "S1 Edge" (terminal 9)
intervene while the door opens with a stop and while it closes
with a brief inversion of movement.
8 - LED INDICATION
With the control unit powered up (if control unit protection is not
activated) the yellow "Set" led flashes briefly and, if everything is
correctly hooked up, the red "S1 Edge","Stop" and "S2 Photo"
LEDs turn on to indicate that the three safety contacts are closed
circuits.
The yellow "Set" LED is exclusively reserved for programming.
8.1 - INPUT STATUS INDICATION LEDS
RED S1 EDGE LED:
- ON in the fixed mode if the S1 Edge contact (terminals 9-10) is
closed
- OFF if the S1 Edge contact (terminals 9-10) is opened
RED START LED:
- ON in fixed mode if the Start contact (terminals 7-8) is closed
- OFF if the Start contact (terminals 7-8) is opened
RED STOP LED:
- ON in fixed mode if the Stop contact (terminals 6-8) is closed
- OFF if the Stop contact (terminals 6-8) is opened
RED S2 PHOTO LED:
- ON in fixed mode if the S2 Photo contact (terminals 4-8) is
closed
- OFF if the S2 Photo contact (terminals 4-8) is opened
YELLOW SET LED:
- is on in fixed mode or flashes when the control unit is in a
programming menu
- is off when the control unit is in out of a programming menu
RED RADIO LED:
- flashes when a command is received through KING transmitter
- is on in fixed mode when the control unit is in a radio
programming menu
- is off when the control unit is in standby mode
RED ERROR LED:
- see paragraph 8.2
RED ERROR LED, RED RADIO LED AND YELLOW SET LED:
- If, when attempting to enter any programming scheme, the
"Set", "Radio" and "Error" LEDs flash fast three times, it
means that the "control unit protection" is activated. See
Paragraph 14.1 for solving the problem.
8.2 - LED ERROR
RED "ERROR" LED:
The red "error" LED has two functions:
- During automation's movement, the LED flashes when a
mechanical stress point is detected (this corresponds to
increased motor effort). Adjust FORCE and OBS knobs (slightly
turn them clockwise) to solve this and check gate mechanics if
necessary.
Attention: a minimum flash of this LED during the door
movement can be considered as normal.
- In standby mode, the LEDs shows the current error type with a
series of regular flashes according to the following scheme:
N. flashes Error description
1 On-board memory fault
2 Photo-test of safety devices failed. See
Paragraph 4.1 for solving the problem
3
Automation's movement programming
required. See Paragraph 6
4 Input "S1 Edge" set as a resistive edge and
check failed. See Paragraph 13.2 for solving the
problem
5
Power limit threshold
6 Obstacle detection due to encoder
7
Obstacle detection due to current
9 - 13 Electronic protections activated
14
Supply voltage too low
15 Temperature too high
