MCP-4 Compatibility
The MCP-4 has a dual-channel (four-wire) E-Stop circuit in which the switch contacts are
in parallel. This is different from the MCP III, in which 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, there are 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.
