Light Curtain: Advantages/Disadvantages

Advantages• Enables access to and ergonomic

operation of the machine• In combination with a muting system,

enables unhindered material transport through the protected field

Disadvantages• Safety distance required• No protection against injury caused by

flying parts


Safety category differences

Fault Detection:

Type 4 safety light curtains are designed to immediately detect the failure of a single component

Optical Angle:

Type 4; +/- 2.5 ° Type 2: +/- 5 °

Price:

Type 2 typically 15 to 30% less expensive

Features:

Type 4 will typically have additional features such as blanking, muting, initiation, and other safety related control functions.

Components:

Additional micro-processors, on-board redundancy.


Type 4 = Control ReliableCSA Z434-03, 4.5.5

Parameterization

3 Ways to set Parameters of COMPACTplus:

• by integrated DIP switches on the display pcb

• by teach in with the SafetyKey

• by setting with the SafetyLab software

Competitive Advantage against Competitors, who offer only 1 choice

SafetyLab..

…Is the PC software for:• Display and Diagnostic of

• the state and parameters of the protective field• the state of external and internal signals• the occurrence of error events• the sequence of signal changes saved on disk -> data recorder

• Adjustment of all parameters in Assistant or Expert mode like• transmission channel, scan mode, display settings• start / restart interlock, contactor monitoring, additional safety circuit• protective field parameters for blanking, reduced resolution, signal

beams• teach-in control• muting -modes, -signal sources, -time limit, -lamp parameters• initiation mode, mode control switch, control signals• additional enable signals, signal filtering


SafetyLab Diagnostic: Protective Field

• Shows 7-segment display and LEDs of the device• Display of the beam state depending on beam parameterization by

colors:• light green = free and expected as free (free normal beam)• dark green = interrupted and expected as interrupted (interrupted blanked beam)• red = interrupted and expected as free (interrupted normal beam)• yellow = free and expected as interrupted (free blanked beam)

• Beam parameters can be displayed optionally


Parameter Module

feature to improve maintainability

Contains all operating elements and all application specific parameters, also those settings coming from SafetyLab like- timing expectations- signal shunting- passwords ...

advantage: the complete parameter set can be easily transferred to a same-type spare device without SafetyLab

Interfaces

The type of the electrical connection is independent of the function package.

Every connection type is available in every function package.

All COMPACTplus have a Local Interface and a Machine Interface.

Local Interface: to connect locally push buttons, key locks, signal lamps,

SafetyKey, PC adapter, ..

• Local Socket: 1 M12 socket 8-pole

• Sensor Module: 5 M12 sockets 5-pole

Machine Interface: to integrate the safety sensor into the machine control

• COMPACTplus /T: Transistor - output, 2 x 0,5A, MG / Hirschmann / MIN

• COMPACTplus /R: Relay - output 230VAC / 24VDC, MG / Hirschmann / MIN

• COMPACTplus /A: ASIsafe - AS-interface for Safety at Work


Local Interface

Local Interface (M12x8 Plug) in the end cap for the connection to local devices like restart button, muting sensors, emergency stop button, safety door interlock, ...
