Message Description Possible solutions
They point out that the gate has excee-
ded:
-(Err1), the max allowed number of
reversals (50) without ever reaching the
end of stroke (or stop) while closing;
-(Err2)themaxnumberofuninterrupted
operations (10) of the anti-crush safety
device;therefore an “emergency maneu-
ver”isunderway:thecontrolboardsets
the motors in a slow down phase and
searches the stops (or ends of stroke)
in order to reset the positioning system.
Oncethestops(orendsofstroke)while
closing are found again the message
disappearsandthecontrolboardawaits
further instructions “----” and then resu-
mesworkingnormally.
In case the gate is not properly closed after the
emergency maneuver (maybe because of false
stops or obstacles due to mechanical frictions),
proceedasfollows:
- Disconnect the power supply,  check manually
that no particular frictions and/or obstacles are
presentduringthecompletestrokeofbothleafs.
Leavebothleafshalf-open.
-Connectthepowersupplyagainandsubsequen-
tlygiveastartpulse.Atthispointbothleafswill
starttocloseinslowdownphaseuntilreachingthe
stop(orendofstroke).Makesurethatthemaneu-
verisproperlycompleted.Adjustforceandmotor
speedvalues,ifneedbe.
Ifthegatekeepsworkinginappropriatelytryto
repeatthemotorstrokememorizationprocedure
