The following can be monitored (up to PLe) using the expansion modules for
speed monitoring SPM0, SPM1 and SPM2:
Standstill, overspeed, speed range
Direction of motion, rotary motion/linear motion
Up to 4 speed limits can be defined for each logical output (axis).
Each module has two logical outputs that can be configured via EUCHNER Safety
Designer. In this way up to two independent axes can be monitored.
The safety modules AZ-FO4 and AZ-FO4O8 have 4 separate safety relay outputs
and the corresponding 4 inputs for the external device monitoring contacts (EDM).
Two settings are available for the outputs (configuration via the software
EUCHNER Safety Designer):
2 pairs of connection contacts (2 normally open contacts per output with 2
corresponding feedback loop inputs).
4 separate individual connection contacts (1 normally open contact per out-
put with 1 corresponding feedback loop input).
Only the module AZ-FO4O8 has 8 programmable signal outputs.
Using the software EUCHNER Safety Designer, complex logic can be configured us-
ing logical operators and safety functions such as muting, timers, counters etc.
defined.
All this is achieved using a straightforward, intuitive graphic user interface.
The configuration undertaken on the PC is transferred to the MSC-CB via a USB
connection. The file is saved in the MSC-CB and can also be saved on the proprie-
tary M-A1 memory card (accessory). In this way it is possible to copy the configu-
ration to a different MSC-CB module quickly.
The MSC system is certified for the highest safety level included in the applicable in-
dustrial safety standards (SIL 3, SILCL 3, PL e, cat. 4).
