Description
The hydraulic mode function allows controlling a hydraulic motor that has a pressure
switch output signal.
Configuration
To enable the hydraulic mode function it is needed to configure any of the available
inputs as “Pressure switch” by means a VERSUS-PROG programming tool. The
P5E
to
P60
configuration parameters are used to configure the control panel inputs.
There are two cases where the pressure switch is activated: when there is any kind of
obstacle that doesn’t allow the motor movement and when the motor starts moving.
-
The first case is very useful in order to use the pressure switch as a security
signal and also to use it to detect OPEN and CLOSE references during
programming sequence process. When control panel maneuvers are
programmed, if user reaches the top and bottom door limits and the hydraulic
motor presses for an extratime, that is configured by
P2D
parameter, in these
points, OPEN and CLOSE references are detected. Therefore in normal
operation these references will be taken into account. To check if these
references have been detected
P1F
and
P20
status configuration parameters
can be used. The ON value means that the reference has been detected. In
case of 2 motors model (M22), the detection of the second motor is performed
by
PD3
and
PD4
parameters.
-
The second case is very useful in order to test pressure switch signal. If a
pressure switch signal pulse is detected every time that the motor starts
moving, this signal can be checked to perform the pressure switch autotest. In
order to define the zone where this activation is possible and to inhibit the
pressure switch security signal
P42
parameter is used. Therefore every time a
maneuver starts during the time configured by
P42
pressure switch is inhibited
and if test is enabled it checks that it is active during a short period of time. To
enable or disable the pressure switch test it is necessary to assign the
“Pressure switch test ON/OFF” function on any of the switches. This
configuration can be done by using the
P54
to
P5C
configuration parameters.
If none switch is configured autotest is enabled by default.
