■Overview

■Function

 

 

 

 

 

Safety monitor with enlarged functions

 

 

 

 

 

Logical OR operation

 

 

 

 

 

In this logical operation up to six elements can be OR gated.

 

 

 

 

 

(Until now, only two elements could be OR gated).

 

 

 

 

 

Logical AND operation

 

 

 

 

 

In addition to the standard AND gating in the main path of an

 

 

 

 

 

enabling circuit, an AND operation can be inserted into an OR

 

 

 

 

 

operation. More than two elements can be gated in this AND.

 

 

 

 

 

Buffer

 

 

 

 

 

Temporary shutdowns are stored in a buffer for the purpose of

 

 

 

 

 

diagnostics.

 

 

 

 

 

Number of devices

 

 

 

 

 

The number of devices that the safety monitor can process has

 

 

 

 

 

been increased from 32 to 48. Applications that are larger and

 

 

 

 

 

more complex can now be simulated in the safety monitor.

 

 

 

 

 

Timer functions

 

 

 

 

 

Timers are offered with the functions

 

 

 

 

 

• Delayed switching-on

 

 

The safety monitor is the core component of Safety at Work. A

 

 

• Delayed switching-off and

 

 

 

 

• Pulse.

 

 

safe application is configured with a PC via the safety monitor.

Compatibility

 

Various different application-specific operating modes can be

 

 

 

used. These include the EMERGENCY-STOP function, tumbler,

 

 

Any configurations that have been previously created can be

 

two-handed operation as well as selection of Stop category

 

 

 

 

 

 

 

 

 

0 or 1.

loaded into the "new" safety monitor without changes.

 

In order to fully utilize the AS-Interface diagnostic capability, the

 

monitor can also be operated with AS-Interface addresses as an

 

alternative.

 

Two versions of the monitor are available:

•Safety monitor with one two-channel release circuit

•Safety monitor with two two-channel release circuits
