P-04: RVC input function
This parameter permits to set type and function related to the RVC command input.
Parameter value
Notes
00 = edge reversing input
signal
(
default value
)
The signal connected to the RVC pin is a dry contact from an external reversing source
(light curtains, photocells, …). The activation of the signal during door closing implies
the door reversing until the complete reopening of the door (according to P-00 settings
that defines if the controllers reopens automatically or waits for a MLC DOC command)
01 = level reversing input
signal
The signal connected to the RVC pin is a dry contact from an external reversing source
(light curtains, photocells, …). The activation of the signal during door closing implies
the door reversing and reopening until RVC is active (according to P-00 settings that
defines if the controllers reopens automatically or waits for a MLC DOC command)
02 = mechanical safety
edge
The signal connected to the RVC pin is a dry contact from an external retractable safety
edge. In this case the controller applies a signal filter to disable the input signal based to
the door position, when the door is in the “blind zones” of the safety edge, that means
the positions where the edge retracts automatically near to the door opened position
and near to panels closed position.
The values of these “blind zones” are programmable as parameters:
“Disabling threshold start closing P-68”: default 50mm, adjustable from 0mm to 150mm
“Disabling threshold end closing P-69”: default 50mm, adjustable from 0mm to 150mm.
The diagram below reports the “blind zones” position:

P-21: RVC input logic settings
This parameter allows to set the RVC input signal logic.
Parameter value
Note
00 = OFF
The signal connected to RVC input is not active
01 = Normally OPEN
(
default value
)
The signal connected to RVC input is normally open signal
02 = Normally CLOSED
The signal connected to RVC input is normally closed signal
