NOTE:
The MSD’s Ethernet interface is NOT designed to be used for safety
-critical applications. It is exclusively a
system status and information mechanism.
The MSD is offered with three different physical BUS configurations, these are;
1. No bus fitted
2. EtherNet/IP (also supports Modbus TCP)
3. PROFINET (also supports Modbus TCP)

8.7 MSD Operation
The MSD is a critical part of your machine control system. For reliable operation, it is important that it is operated
within designed limits as directed and is maintained in good order.
As long as the MSD remains powered on, the only interaction that may be required will be the result of one or
more PSDs leaving RF range, resulting in communication loss for longer than 30 seconds. This condition requires
the remaining users to confirm that the user of the offending PSD was not subject to an accident. To enforce this
check, all PSDs will automatically unlink and the MSD will require its COMM LOSS RESET button to be pressed
as a confirmation before any PSDs are able to re-link.
The reset button is wired into one pair of the MSD's safety inputs, enabling the button to be placed at a
convenient location near the operators.
8.8 MSD Installation
8.8.1 Safety Instructions for Installation
Only trained and qualified persons may perform installation and maintenance work.
NOTE:
Ensure suitable and appropriate transient protection devices are fitted to the relay’s contacts. Ensure
correct wiring of the machines’ main contactors and reset circuits. Use appropriate gauge wiring and
under no circumstances use wire of less than 24AWG. Ferrules should be used to protect against loose
wire strands and proper insertion into the terminals. Thoroughly test each hard-wired and
Safe-E-Stop MSD prior to handing over to production.
▪
Isolate the system from the electrical power in accordance with the applicable regulations.
▪
Observe user-specific regulations.
▪
Only use suitable tools.
▪
Secure the installation area.
8.8.2 MSD Installation Notes on Enclosure
The MSD must be housed in a secondary enclosure for protection; a suitable option kit (2OPT-8637-A102) is
available from Cattron. This enclosure provides visibility to the MSD. This allows local users to better understand
