Safety Functions

Operation Modes

Auto Start

If no objects are detected in the sensing area when the power is

turned ON in Auto Start Mode, the system enters the Machine Run

State. If an object is then detected, the system changes from the

Machine Run State to the Machine Stop State, and remains in that

state until the object is removed. When the intrusion into the sensing

area disappears, the system automatically changes from the Machine

Stop State to the Machine Run State.

Start Interlock

If no objects are in the sensing area when the power is turned ON in

Start Interlock Mode and an alarm (lockout) condition does not occur,

the system enters the Interlock State. To shift to the Machine Run

State, an operator must press and release the Start Button on the

Safety Light Curtain. If an object intrudes in the sensing area during

the Machine Run State, the system will change to the Machine Stop

State. When the object is removed from the sensing area, the system

will automatically shift to the Machine Run State.

Start/Restart Interlock

If no objects are in the sensing area when the power is turned ON in

Start/Restart Interlock Mode and an alarm (lockout) condition does

not occur, the system enters the Interlock State. To shift to the

Machine Run State, an operator must press and release the Start

Button on the Safety Light Curtain. If an object intrudes in the sensing

area during the Machine Run State, the system will change to the

Machine Stop State. When the object is removed from the sensing

area, the system will shift to the Interlock State instead of

automatically shifting to the Machine Run State. To shift to the

Machine Run State, an operator must press and release the Start

Button. When there is an object in the sensing area, the Start Button

is disabled.

Blanking Functions (Advanced Series

Only)

Fixed Blanking

This function is used when a machine or workpiece constantly

interrupts beams in a part of the sensing area. Fixed blanking allows

the Safety Light Curtain to remain in the Machine Run State while the

obstruction in the sensing area as a non-moving object. The output is

turned OFF when a beam other than the set fixed blanking beams is

interrupted, or when light is incident on a fixed blanking beam.

Floating Blanking

This function turns OFF the output when the total number of

interrupted beams inside the sensing area exceeds the number of set

beams (1 or 2).

Monitored Blanking

This function is used when a machine or workpiece constantly

interrupts beams in a part of the sensing area and moves within the

sensing area. Monitored blanking allows the Safety Light Curtain to

remain in the Machine Run State while the obstruction moves within

the sensing area. The output is turned OFF when the machine or

workpiece disappears from the monitored blanking area that was set

by teaching, or when the total number of interrupted beams increases

due to a different obstruction.

Reduced Resolution Blanking

When the resolution of the MS/MSF4800A is reduced, the size of the

minimum detectable object is increased. The output will not turn OFF

regardless of how many continuous interrupted beams there are in

the sensing area as long as the beams are fewer than the set number

(1, 2, or 3 beams).

When an object whose size exceeds the set number of beams

intrudes, the output is turned OFF. For example, in an application

where a conveyor cart approaches a robot work area, the Safety Light

Curtain can be set so that it does not detect only the wheels of the

cart, allowing the MS/MSF4800A to be used as a presence sensing

device.

Muting Functions

Use of the MS4800-RM6 Resource Module (sold separately) makes

it possible to temporarily disable the Safety Light Curtain. Select from

among four muting modes to match each application with the

appropriate number and placement of muting sensors.

Note: For details on blanking and muting, refer to the Mini Safe 4800

Series Safety Light Curtains Installation and Operating Manual.
