SECTION 4
System Operation
The MS2800 system is a microprocessor-controlled, infrared, transmitted-
beam safety light curtain. The system consists of a receiver assembly and a
transmitter assembly. The receiver and transmitter assemblies are not physi-
cally interconnected.
It complies with a Type 2 according to EN/IEC 61496 and category 2 accord-
ing to EN954-1.
An MS2800 system is used where personnel protection is required. Typical
applications include packaging machines, back side protection of presses and
textile machinery.

Operating States
The operating condition of an MS2800 system is described in terms of states.
The following operating states exist for an MS2800 system.
4-1-1
Machine Run
The two receiver safety outputs are in the ON state, the green MACHINE RUN
indicator is lit, and the auxiliary output is in a state consistent with its configu-
ration. The protected machine is allowed to operate. Pressing and releasing
the start button has no effect.
4-1-2
Machine Stop
The two receiver safety outputs are in the OFF state the red MACHINE STOP
indicator is lit, and the auxiliary output is in a state consistent with its configu-
ration. The protected machine is not allowed to operate.
4-1-3
Interlock
The two receiver safety outputs are in the OFF state, the red MACHINE STOP
indicator and yellow INTERLOCK indicator are lit. The auxiliary output is in a
state consistent with its configuration. The INTERLOCK state does not allow
the protected machine to operate until the detection zone is clear of obstruc-
tions and the start button is pressed and released.
4-1-4
Alarm
The two receiver safety outputs are in the OFF state, the red MACHINE STOP
indicator is lit, the yellow INTERLOCK indicator is flashing and the auxiliary
output is in the OFF state. The alarm state does not allow the protected
machine to operate. The primary difference between ALARM and INTER-
LOCK is that the MS2800 system will remain in the alarm state until the alarm
is corrected, and then applying a power cycling or an external start button
press and release.
