2.8 Functions
The system consists of a receiver and a transmitter For the described
functions, no further switching elements are required For the diagnostics
and function selection, a user-friendly PC-software is offered as accessory
For the connection to a PC, the NSR-0801 BUS converter is required
(not included in delivery)
The system has the following features:
• Protective mode (automatic start after release of the protected field)
• Start interlock
• Restart interlock (manual reset)
• Contactor control EDM
• Beam coding
• Blanking of fixed protection field areas
• Blanking of movable protection field areas
Factory setting
The SLC 420 system features many functions without additional
devices The following table gives an overview of the possible functions

2.8.1 Protective mode
The protective mode switches the OSSD outputs to ON state (protec-
tion field not interrupted), without external release of a switching device
This type of protection generates an automatic restart of the machine if
the protection field is not interrupted
This operating mode may only be chosen in conjunction with
the restart interlock (manual reset) of the machine
This operating mode must not be chosen, when persons can
step behind the protection field
2.8.2 Restart interlock (manual reset)
The restart interlock (manual reset) prevents an automatic enabling of
the outputs (OSSD's ON state) after switch-on of the operating volt-
age or an interruption of the protection field The system switches the
outputs only to ON state, when an external command device (restart
button) generates an enabling signal at the restart input (receiver)
The command devices (enabling button) must be installed
outside of the hazardous area The operator must have a
clear view on the hazardous area when actuating the ena-
bling button
In supply condition, the restart interlock (manual reset)
neither the protective mode is active You must choose one of
both operating modes to enable the OSSD outputs If no type
of protection is selected, you will obtain the following signali-
sation through the LED status indication in the receiver:
LED OSSD OFF (red) + LED restart (yellow) flashing
