No Monitoring:
Use this configuration to perform the initial checkout; see
"Initial Checkout Procedure" on page 35
.
If the appli-
cation does not require the EDM function, it is the user's responsibility to ensure that this configuration does not create a haz-
ardous situation.
To configure the System for No monitoring, jumper EDM1 (orange wire, pin 3) to EDM2 (orange/black wire,
pin 2).
"Generic Wiring Diagrams" on page 47
for “no monitoring” wiring. Set the configuration DIP switch to E2, per
, and connect EDM1 (orange wire, pin 3) to +24 V DC. This method allows the ability
to use the auxiliary output (see
) in applications that do not require the EDM function.
An aux. output function is available when the receiver is configured for 1-channel EDM (for receivers with date code 0834 or
newer). This current sourcing (PNP) solid-state output (75 mA maximum) is used for control functions that are not safety re-
lated. A typical use is to signal the state of the OSSDs to a programmable logic controller (PLC). The aux. output follows the
state of the OSSDs. Pin 2 (orange/black) supplies the connection; see
"Generic Wiring Diagrams" on page 47
To use the auxiliary output in an application configured for no monitoring:
There are no compatibility issues retrofitting receivers with aux output into earlier installations, if precautions are taken to pre-
vent EDM2 (pin 2, orange/black wire) from shorting to ground or another source of energy.
The 5-pin
EZ-SCREEN SLS
emitter models (model numbers SLSE..-..Q5) provide a Test function. A pair of wires is connect-
ed from the emitter to an external switch, typically a normally open contact, held closed. Opening the switch “turns off” the
emitter, simulating an interruption of one or more light beams; all OSSD outputs will turn OFF.
This remote test input function may be useful for
EZ-SCREEN SLS
setup and to verify machine control circuit operation.
Electrical Connections to the Guarded Machine
After the initial trip test has been accomplished, and the OSSD safety outputs and EDM connections have been made to the
machine to be controlled, the
EZ-SCREEN SLS
is ready for testing in combination with the guarded machine.
The operation of the
EZ-SCREEN SLS
with the guarded machine must be verified before the combined System and machine
This wiring option provides sensor interchangeability (or “swapability”)—the ability to install either sensor at either QD con-
nection.
To wire the emitter, use only three conductors (Brown = +24 V DC, Blue = 0 V DC, and Green/Yellow = GND). Connect the
remaining wires in a parallel connection (color-for-color) to the receiver cable. The resulting installation provides the ability to
swap the emitter and receiver position. This wiring option provides advantages during installation, wiring, and troubleshoot-
ing.
