Operating If any input is configured as “Pressure switch”, the control panel is working on
hydraulic mode. In this mode is always using Time mode by default. Hall mode is not
allowed in hydraulic mode.
In normal operation, the pressure switch signal is used as security signal if it is not
inhibited. The signal is inhibited the first seconds of the maneuver. This time is the
configured inhibition time and during this time if the pressure switch test is enabled it
checks its activation. In order to inform the user that the pressure switch signal is
inhibited the STOP/ERROR control panel red LED flashes. After leaving this inhibition
zone the pressure switch is used as a security signal and if there is any activation
control panel executes the security inversion maneuvers. It is possible to inhibit
the pressure signal during the entire opening operation by assigning this function to
a selector with parameters
P54 to P5C .
In addition if any reference has been programmed by using the pressure switch signal
(OPENED or CLOSED), the security signal is also inhibited 2 seconds before reaching
the reference point detection. In this case the STOP/ERROR control panel red LED it
also flashes to inform the user that it is inhibited in order to detect the OPENED or
CLOSED reference. Once reached the reference and to ensure proper closing or
opening of
the door, the door continue closing / opening for the extra
time parameter set by P2D .
If pressure switch test is enabled and there is no signal activation during the inhibition
zone, test fails and
Er19 error is displayed in case of closing maneuver test and Er20
error is displayed in case of opening maneuver test.
During normal operation any pressure switch activation that results into a security
maneuver, displays the
Wr40 warning in order to inform the user that a pressure switch
security signal has been detected.
Notes Slow speed mode is not allowed if hydraulic motors are used.
If due to maintenance it is necessary to repair the hydraulic motor it is possible to
temporally replace it by a electromechanical motor. In this case pressure switch test
has to be disabled if it is enabled and the pressure switch input can be replaced by a
normally closed contact (bridge).
If hydraulic motor is used and door is in OPENED or CLOSED position for a long period
of time it is highly recommended to enable the “Recharge maneuver” function in order
to keep the door correctly opened or closed (see 7.24).
