Set Outputs for Failsafe or Compatibility
When SW3 is on, the sourcing outputs of the SD220/SD230 provide the same logic levels as the outputs
of older double shell units such as the DS33 and DS35, allowing for quick and easy retrofit installations.
When SW3 is off, the output states are defined to provide maximum protection against loss of
connection between the shell detector and the controlling PLC. The loss of connection is sensed as the
fault condition.
The table below defines the output states for all combinations of SW3 and the possible sensing states.
Also, see the SD220/230 Output Signal Drawings (page 18).

Enable or Disable Tab Profiling
The SD220/SD230 uses two different methods for determining the absence or presence of tabs. The
most basic method is simple thresholding of the sensor signals. As the shape of the beverage ends and
tabs evolved and the speed of presses increased, it became necessary to implement a redundant test
that recognizes the profile of a tab as it moves through the machine. This feature, however, is not
compatible with larger and steel ends or with machines that have stainless steel belts. The stainless steel
belts can change the sensor signal sufficiently to interfere with the tab profiling algorithm and cause the
system to report self-check errors. Profiling is most effective in the detection of aluminum tabs on
aluminum ends on high-speed presses. SW6 enables and disables tab profiling.
Setting Options Through the Front Panel
Set TriSense Mode (SD230 Only)
By default, the system does not enable TriSense mode (tr= 0). In this mode, the SD230 operates stand
alone and presents Modbus entities related to its operation alone. TriSense mode is enabled by setting
the tr setting to 1 or 2 depending on if the Flash Detect input is used. Unused, TriSense mode is 1. Used,
TriSense mode is 2. To set the TriSense mode:
1. Press and hold the calibrate pushbutton until “tr” appears on the display.
2. Release the pushbutton and the display changes to “0”, “1”, or “2”.
3. At this point, with each press of the pushbutton the display increments up to 2 and rolling over
back to 0. The 0 disables TriSense, 1 enables TriSense without Flash Detection, and 2 enabled
TriSense with Flash Detection.
4. When the desired value is on the display, wait 5 seconds and the display reverts to displaying
the signal value in the selected mode.
