MCP-4 Compatibility
The MCP-4 has a dual-channel (four-wire) E-Stop circuit where the switch contacts are in
parallel. This is different from the MCP III where the switch contacts are in series. This
difference affects how the MCP-4 is used in various Adept systems.
Table C-1 covers the
compatibility status for the MCP-4.
Table C-1. MCP-4 Compatibility Guidelines
In Adept systems rated for Category 1 Safety
In MV Controller-based
systems with CIP2, CIP1, or
VFP MCP-4 is compatible, no issues
In SmartController-based
systems In systems that are shipped from the factory with an MCP-4, there are
no compatibility issues.
If you are installing an MCP-4 in a system that originally used an MCP
III, then Adept recommends removing 10356-10370, CIM TO MCPIII
Adapter for reliability, but not for compliance reasons.
In Adept systems rated for Category 3 Safety (CE: Redundant Channel, RIA: Control Reliable)
In MV Controller-based
systems with CIP2 or CIP1 To maintain a dual contact enable in CE Category 3 Emergency Stop
systems, remove jumper JP3 inside CIP.
In MV Controller-based
systems with VFP3 MCP-4 not compatible. Cannot maintain a dual contact enable with the
MCP-4, must use MCP III.
In SmartController-based
systems In systems that are shipped from the factory with an MCP-4, there are
no compatibility issues.
If you are installing an MCP-4 in a system that originally used an MCP
III, then you must remove 10356-10370, CIM TO MCPIII Adapter. This
must be done for compliance reasons in order to maintain a dual
contact enable in CE Category 3 Emergency Stop systems.
