TABLE 2 - List of IRW interface terminals to connect the interface to the control unit.
Terminals Type of wire
12 - 24V 2 x 0.5 mm
PHOTOTEST 1 x 0.25 mm
ALT
2 x 0.25 mm
ALT 1
2 x 0.25 mm
Note – The "Alt" output can be transformed into an 8.2 kohm output by breaking the connection on the interface circuit board as shown in fig. 10.
TABLE 3 - Description of the outputs on the IRW interface
Output Circuit status
ALT closed
open (> 50 kohm)
ALT1 closed
open
Note – The "Alt" output must be connected to the "Alt" (or 8.2 kohm) input on the unit, which causes the halting and eventual reversal of the movement,
normally used for pressure-sensitive safety devices (PSPE).

Description
Both edges connected to the interface are not subjected to pressure.
At least one edge connected to the interface is under pressure.
Both edges connected to the interface are not subjected to pressure.
At least one edge connected to the interface is under pressure.
Description
Interface power supply; direct current or alternating current.
Input for test at start of manoeuvre. Can be connected to direct current or
alternating current voltages.
Output 1 - 82kohm constant resistance or normal closed contact (NC) when the
edge is not activated: instantaneus intervetion. In Nice central unit, if phototest is
used the "alt" input of the central unit must be connected to the "alt" output of
the IRW.
Output 2 - Normally closed (NC) contact when the edge is not activated:
intervention delayed by 1.5 seconds. In Nice central unit, if phototest is used the
"photo" input of the central unit must be connected to the "alt1" output of the
IRW.
