1.6 CAT-3 Version of SmartController
Identification
The Adept SmartController has been modified to be compatible with Category 3 safety
requirements. The CAT-3 version of both the CS and CX models of the SmartController
can be identified by the serial number on the front of the controller.
Functionality Changes
MCP Enable Switch Not Functional in Auto Mode
The CAT-3 version of the SmartController has a significant functional difference from the
original SmartController. When a CAT-3 SmartController system is operating in Auto
Mode
, the Enable Switch on the MCP has no effect on the operation. This means in the
Auto mode, the Enable switch does not have to be pressed to enable High Power, and
releasing the Enable switch while running will not turn off High Power. This is true for
both the MCP-3 and MCP-4 models.
High Power Indication on XDIO Connector
In the CAT-3 SmartController, a V + controlled, normally open relay contact, on the XDIO
connector (pins 45 and 46), will close when High Power has been enabled. The user can
use this feature to power an indicator lamp, or other device, that signals High Power is
On.
E-Stop Circuit
The CAT-3 SmartController modification is shown in the E-Stop diagram in Figure 3-4 on
page 52 . The change from the original SmartController circuit is evident in the center area
of the drawing at the MCP-4 Enable switch.

habits adjusted accordingly.
