Automatic Searching; Searching With The Current Sensitivity Device Disabled - Nice mindy A400 Instructions Et Recommandations Pour L'installation

2.5.1) Automatic searching

This procedure is completely automatic and detects the
mechanical opening and closing stops by measuring the load on
the motors.
In "particularly difficult" automated systems, the system for detecting
the variations in motor current may not work correctly; try changing the
current sensitivity device cut-in level or else revert to exclusively timed
operation; see the "Search with current sensitivity device disabled"
section.
• Before beginning automatic searching, make sure that all the safety
devices are enabled (STOP, PHOTO and PHOTO1 active). The
procedure will be immediately interrupted if a safety device triggers
or a command arrives.
• The doors should preferably be about half open but they may be
in any position.
• Press the PP button to begin the searching phase,
comprising:
P1 P2
STOP PP
– Motors open briefly, first M2 and then M1.
If the motors do not start during the opening cycle or if the first to
move is not M2, press STOP to interrupt the search and check the
motor connections.
2.5.2) Searching with the current sensitivity
device disabled
If the current sensitivity device does not work correctly, the control
unit can work to timed cycles, totally excluding the current sensitivity
function. (to disable the current sensitivity system, see the
"Programming parameters and functions" section).
In this case the fitter "tells" the control unit when the mechanical stop
has been reached.
• Before beginning searching with the current sensitivity device
disabled, make sure that all the safety devices are enabled (STOP,
PHOTO and PHOTO1 active).
• The doors should preferably be about half open but they may be
in any position.
• Press the PP button to begin the searching phase,
comprising:
P1 P2
STOP PP
– Brief opening, first M2 and then M1.
If the motors do not start during the opening cycle or if the first to
move is not M2, press STOP to interrupt the search and check the
motor connections.
– Motor M1 closes until the closing mechanical stop is reached.
8
– Motor M1 closes until the closing mechanical stop is reached.
– Motor M2 closes until the closing mechanical stop is reached.
– Motor M2 begins opening.
– After the programmed delay, motor M1 begins opening.
If the delay is not sufficient, press STOP to interrupt the search and
modify the time (see the "Programming" chapter).
– Measurement of the time required for the motors to reach the
opening mechanical stops.
– Complete closing manoeuvre.
The motors can start at different times, the aim is to prevent the leafs
from shearing by maintaining a suitable delay.
– End of the procedure with memorisation of all time measurements.
All these phases must take place one after the other without any
interference from the operator. If this does not happen, the
procedure will not continue correctly and must be interrupted with
the STOP button. Check the connections and then repeat the
procedure, modifying the current sensitivity cut-in thresholds if
necessary (see the "Programming" chapter).
• Press PP when M1 reaches the closing mechanical stop.
– Motor M2 closes until the closing mechanical stop is reached.
• Press PP when M2 reaches the closing mechanical stop.
– After a few moments the M2 motor begins the opening cycle.
• Press PP when M2 reaches the opening mechanical
stop.
– After a few moments the M1 motor begins the opening cycle.
• Press PP when M1 reaches the opening mechanical
stop.
– After a few moments a complete closing cycle begins.
The motors can start at different times, the aim is to prevent the leafs
from shearing by maintaining a suitable delay.
– End of the procedure with memorisation of all time measurements.
All these phases must take place one after the other; the fitter must
only press PP when required. If procedure does not continue
correctly, press the STOP button to interrupt it. The procedure will be
immediately interrupted if a safety device triggers or a command
arrives.
