2.2 Destination and use
When used as intended, the AS-i safety monitor enables the operation
of sensor-controlled devices for the protection of man and other safety
components up to and including control category 4 / PL e to
EN ISO 13849-1. If sensors with a lower safety levels are connected,
the maximum achievable control category for the corresponding safety
path is defined by these sensors.
The safety monitor also executes the compulsory emergency stop
function (stop category 0 or 1) for all non hand-operated machines as
well as the dynamic monitoring of the restart function and the contactor
control function.
The setting and modification of the device configuration by
means of a PC and the asimon configuration software must
only be executed by a safety expert authorised to that effect.
The password required to change the device configuration
must be locked away by the safety expert.
Suitable for:
• Safety monitor for 1 AS-i circuit
• Monitoring of up to 31 safe AS-i slaves, e.g. safety switches, solenoid
interlocks, emergency stop buttons, two-hand controls, light curtains
and light grids, etc.
• Control of up to 2 redundant enabling circuits
• Configurable monitoring devices for the different safety switchgear
• Filter functions for de-bouncing of safety guards
• Other functions:
AND operations, OR operations, start modules, on-site
acknowledgment, start-up test, stop categories 0 and 1
• Edge-sensitive start button
• Feedback circuit to monitor external contactors
• LED status indication
• Signalling outputs (semi-conductor, short-circuit proof)
These devices are not suitable for:
– Controlling safe AS-i outputs
– Network connection of 2 AS-i circuits
The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant
standards.
