SECTION 3
System Operation
The F3S-TGR-CL system is a microprocessor-controlled, infrared, transmit-
ted-beam safety light curtain. The system consists of a receiver assembly and
a transmitter assembly. The receiver and transmitter assemblies are not phys-
ically interconnected.
It complies with a Type 2 or Type 4 according to EN/IEC 61496 and up to PLc
or PLe according to EN ISO 13849-1 (2008), depending on the model .
A F3S-TGR-CL system is used where personnel protection is required, typical
applications include packaging machines, front- or back side protection of
presses and textile machinery.

Operating States
The operating condition of a F3S-TGR-CL system is described in terms of
states. The following operating states exist for a F3S-TGR-CL system.
3-1-1
Machine Run
The two receiver safety outputs are in the ON state, the green GUARD indica-
tor is lit. The protected machine is allowed to operate. Pressing and releasing
the restart button has no effect.
3-1-2
Machine Stop
The two receiver safety outputs are in the OFF state the red BREAK indicator
is lit. The protected machine is not allowed to operate.
3-1-3
Interlock
The two receiver safety outputs are in the OFF state, the red BREAK indicator
and yellow INTERLOCK indicator are lit. The INTERLOCK state does not
allow the protected machine to operate until the detection zone is clear of
obstructions and the restart button is pressed and released.
3-1-4
Error
The two receiver safety outputs are in the OFF state, an error code is shown
via the blinking indicators. The error state does not allow the protected
machine to operate. The primary difference between ERROR and INTER-
LOCK is that the F3S-TGR-CL system will remain in the error state until the
error is corrected, and then applying a power cycling or an external restart
button press and release.
