UTOMATIC TART
The MS4800 will power-up with its safety and auxiliary outputs OFF, and, if the detection zone is not
obstructed, enters the MACHINE RUN state. In this state, when an object is sensed entering the
detection zone, the MS4800 system will change from MACHINE RUN to MACHINE STOP and
remain in this state until the obstruction is removed. Once the detection zone is clear, the MS4800
system will automatically change from MACHINE STOP to MACHINE RUN.

TART NTERLOCK
Start Interlock is only available on MS4800A systems.
The MS4800A will power up with its safety outputs off and enter the INTERLOCK state if the
detection zone is clear (or the Fixed or Monitoring Blanking pattern is satisfied, if enabled) and no
alarms are detected. To initially enter the MACHINE RUN state the operator must press and release
the Start button. Once in the MACHINE RUN state, when an object is sensed entering the detection
zone, the system will change to MACHINE STOP state. When the detection zone is cleared, the
system will automatically change to MACHINE RUN.
S /R INTERLOCK
TART ESTART
Start /Restart Interlock is available on MS4800A, MS4800B and MS4800S systems.
The MS4800 will power up with its safety outputs off and enter the INTERLOCK state if the detection
zone is clear (or the Fixed or Monitoring Blanking pattern is satisfied, if enabled) and no alarms are
detected. To initially enter the MACHINE RUN state the operator must press and release the Start
button. Once in the MACHINE RUN state, when an object is sensed entering the detection zone, the
system will change to the MACHINE STOP state. When the detection zone is cleared, the system will
not automatically change to MACHINE RUN but enter the INTERLOCK state instead. The operator
must always press and release the Start button to enter MACHINE RUN. If the detection zone is not
clear the Start button will have no effect.
The definitions above mention a start button. See Section 12–"Connecting to the Machine
NOTE!
Control Circuit" for wiring of the start button.

The MiniSafe 4800 series safety light curtain is available in a "cascaded" version, referred to as the
MSF4800 series. The MSF4800 series allows multiple transmitters/receivers to be "daisy-chained" in
series. This type of arrangement permits the MSF4800 to guard multiple areas of a machine.

EQUIREMENTS
The MSF4800 is offered in protective heights ranging from 240mm to 1800mm for 14/20mm
resolutions, 240mm to 2120mm for 30mm, and resolutions and from 360mm to 2040mm for 40mm
resolutions.
• An MSF4800 system has a maximum size limitation based on the number of beams. A single master
segment cannot exceed 180 beams and the total of the combined segments cannot exceed 256 beams.
• A single slave segment cannot exceed 128 beams.
• An MSF4800 system may have up to four daisy-chained segments, including the first segment. As long
as the total number of beams does not exceed 256.
• The interconnect cable length limitation between any two segments is 10 meters.
• It is possible to mix segments with different resolutions within an MSF4800 system.
