4.2.4 PROTECTION AGAINST UNCONTROLLED MOVEMENT [EN81-20 §6.3.13]
WARNING
Perform these tests only after the previous ones.
To verify that the devices that prevent uncontrolled movement work correctly, you must proceed with the
test required at point 5.8.3 of the rule EN81-50 checking that the control panel and the system work
according to the rule. (EN81-20 § 5.6.7).
4.2.4.1 PRELIMINARY REQUIREMENTS
To be according to the rule EN81-20 the following points must be respected:
- The system shall be provided with a means /switch able to detect unintended car movement
- The control panel, should NOT send commands to the valve and to the motor / pump when the
system is located, with open doors, outside the doors unlocking zone.
NOTE
Before proceeding check on the installation manual of the electrical part which operations, required
for the test, should be performed
4.2.4.2 TESTING OF THE MONITORING SYSTEM
The NGV A3 card performs an automatic diagnostic of the monitoring system at each stroke and goes into
alarm/fault. To test the monitoring system, it is therefore sufficient at the end of any stroke to check
(2.1 Alarm) that one of the following faults is not present: 06, 07,13 ÷ 22
NOTE
If required, a sensor failure can be simulated by removing either connector X10 (FAULT 06) or
connector X11 (FAULT 14) from the board.
In this case, the board must go into alarm. Using the PT01 programmer, check for alarms
(2.1 Alarm), reinsert the previously removed connector (alarm ends) and perform an alarm reset
(3.1 Al/Flt Reset)
