electronic circuit cuts the power and the motor board goes in fault; in this condition to restore a
normal operation a power-off/power-on of the board is required.
If any of the previous anomalies are detected by the diagnostic, the Motor Board goes in fault
condition, showing an “F” on the display. When in fault condition the gate has to be powered off to
be restored.
When in fault condition the Gate Controller put it's state in Out Of Service.
Automatic Accident Prevention Photocell Testing
The logic system periodically runs an operational test of the safety photocells. The first test is
carried out at system start up after power on.
Subsequent tests are made some seconds after the last transit of the gate and at regular
intervals when the gate is not in use.
The test is carried out as follows:
1.
The photocell transmitter is turned off.
2.
After a fixed amount of time the condition of the photocell is checked.
3.
The transmitter is turned back on.
4.
After a fixed amount of time the condition of the photocell is checked.
If at point 2 and/or 4 a condition is detected which is different from what is expected, the Gate
goes into Out of Service.
This test is made after every transit soon after the Aisle has been cleared. If the gate is in
standby the test will be made after a pre configured time:
•
Main-menu/Setup/Diagnostic/Safety polling test seconds
If the test signals a fault the gate will go in Out of Service state until a new test is successful.
The time interval indicated in points 2 and 4 can be regulated with programmable parameter.
Also, the test repetition interval can be adjusted by programmable parameters.
These parameters are in the “Diagnostic Group” (see the annex “Parameter Table”).
Automatic Transit Photocell Testing
If a sensor remains engaged for more than a certain time, a “fault alarm” signal is given.
When the sensor returns to the free status, the signal is stopped. By means of a parameter (see
“Diagnostic Group” in the annex “Parameter Table”) it is possible to change the engaging time
before alarming. This test is performed on all the sensors, even the safety sensor.
Maximum Obscuring Time Test
The diagnostic on the Gate Controller board monitors at any moment how long a photocell
remains obscured. If a photocell is obscured longer than a programmed time, the gate signals a
fault condition. This test is made on all the photocells whether they are transit ones or safety ones.
The maximum time is programmed:
•
Main-menu/Setup/Diagnostic/Sensors engaged max time in seconds unit;
