Emergency Release; Malfunction Causes And Remedies - BFT MICHELANGELO 60 Installation And User Manual

To evaluate correctly the values set, you are advised to carry out a few com-
plete consecutive manoeuvres.
20) EMERGENCY RELEASE (Fig. Y)
WARNING! When an actuator without bar needs to be released, ensure that
the balancing spring is not compressed (bar in the opening position).
21) MALFUNCTION: CAUSES and REMEDIES
21.1) The bar does not open. The motor does not turn.
WARNING: before opening the door, the spring must be unloaded
(vertical boom).
1) Check that the photocells are not dirty, or engaged, or not aligned. Pro-
ceed accordingly. Check the electric edge.
2) Check the correct connection of the drive motor and capacitor.
3) Check that the electronic appliance is correctly supplied. Check the
integrity of the fuses.
4) Use the control unit self-diagnosis (Fig. I-O), to check whether the func-
tions are correct. Identify any possible cause for the fault. If self-diagnosis
indicates that a start command persists, check that there are no radio
transmitters, start buttons or other control devices keeping the start
contact activated (closed).

4) Use the control unit self-diagnosis (see "Acces to Menus"), to check whether
the functions are correct. Identify any possible cause for the fault. If self-
diagnosis indicates that a start command persists, check that there are
no radio transmitters, start buttons or other control devices keeping the
start contact activated (closed).
5) If the control unit does not work, it must be replaced.
6) Check the activation of the reference microswitches by checking the
messages appearing on the control panel display.
7) Lubrificate the guide-ressort tirants in case of rumors or vibrations.
21.2) The bar does not open. The motor turns but there is no movement.
1) The manual release was left engaged. Reset the motorised operation.
2) If the release is in the motorised operation position, check the gearmo- tor
for integrity.
Automatic Closing Time [s]
Set the numerical value of the automatic closing time from 1 to 180
seconds. Automatic closing can be deactivated by the TCA Logic, but
it is always carried out on releasing the TIMER.
Maximum torque [%]
Set from 60% to 99% the maximum torque that activation must be able
to provide before generating an obstacle alarm. With the maximum
value set, the control is disabled.
Acceleration [%]
Special parameter 14 on second-generation universal programmers.
Set a value from 1% to 99% for the acceleration to be applied at the
beginning of each movement.
Opening speed/Closing [%]
Set the numerical value of the speed: 1% corresponds to the slow-
down speed, 99% to the maximum speed.
Braking [%]
Set from 0% to 85% the braking to be applied during the slow-down
phase. The initial slow-down value is automatically calculated accor-
ding to this parameter and the effective movement speed.
Emergency braking [%]
Set a value from 75% to 99% for the braking intensity in case of reversing
movement or emergency braking: any values lower than those set in the
"braking" parameter will be ignored.
Opening value calibration [%]
Special parameter 1 on second-generation universal programmers.
Set the reference value from 0,0 to 100,0 for the required opening
position (see Paragraph Limit Switch Setting).
Closing value calibration [%]
Special parameter 2 on second-generation universal programmers.
Set the reference value from 0,0 to 100,0 for the required closing
position (see Paragraph Limit Switch Setting).
Alarm time [%]
In the case of obstacle detection or photocell engagement for a period
exceeding the time set (ranging from 10 s to 240 s), the SCA contact
closes. The contact is subsequently opened by the STOP command
or by triggering of the closing limit switch. Only active when the SCA
Alarm logic is set to OFF.
If set to 0 s, the SCA contact becomes a connection to the Parky system
(see Paragraph Connection To Parky Car-Park Management System).
Zone [ ]
Set the zone number between a minimum value of 0 and a maximum
value of 127.
