OPERATING INSTRUCTIONS
MODEL SD220 SHELL/TAB DETECTOR
DESCRIPTION
The Model SD220 Shell Detector for conversion press applications is a rugged but
sensitive dual channel instrument designed specifically to detect and report missing
blanks or double blanks at the infeed to a conversion press and to detect and report
ends that exit the press without tabs.
A complete system for one lane of a press comprises a control module housed in an
aluminum enclosure and four probes. One transmitting and receiving probe pair
senses doubles at the press input while the second transmitting and receiving pair
senses the presence or absence of tabs at the press output.

  • Page 3: Control Module

    Control Module The control module allows for fast and easy setup and for quick diagnosis of system errors or problems. Setup is achieved through the simple press of a push-button switch or an external contact closure. Faults are reported on digital displays on the control module and through FAULT outputs that may be connected to a PLC or system controller.

  • Page 4: Probes

    Probes The SD220 may be used with any P15 or P70 series two wire probes or with older model three wire probes including AV, AY, AZ, AZA, and CB probes. When used with older 3 wire probes, the white wire in the probe cable is not used and must remain disconnected.

    If both channels calibrate successfully, calibration is complete. The calibration process may also be initiated through an external switch or signal controlling the CAL+ and CAL- inputs to the SD220. Activation of this input performs the same function as pressing the CALIBRATE push-button switch for the corresponding channel.

  • Page 6: Mounting The Control Module

    Note: Prime Controls assures compatibility with PN: CBL101-XX cables and the cabling pre-attached to certain probes. Other types of cabling, and also, cable lengths above 30 meters (approx 100 ft) are not advised.

    AUX inputs may be wired to provide external control of the sensing mode of the SD220. Connect a sinking driver or contact to the AUX- terminal and connect the AUX+ terminal to the 24 volt supply. Connect a sourcing driver to the AUX+ terminal and connect the AUX- terminal to COM.

    Set Outputs for Failsafe or Compatibility When SW3 is on, the sourcing outputs of the SD220 provide the same logic levels as the outputs of older double sheet 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.

    0% to 90% for off-press sensing only (SW2 On) Special Functions The SD220 offers two sets of optically isolated inputs on each channel that provide added control over the unit. These are the remote calibration input terminals labeled CAL+ and CAL- and the sensing mode inputs labeled AUX+, AUX-.

    The revision number is displayed directly on the digital display. The two channels of the SD220 are independent and may be running different versions of firmware. Each must be checked separately.

    3. If your installation uses the AUX input to quickly change between calibrations on different shell materials, it is necessary with the SD220 to activate the AUX input on both channels independently. The AUX inputs are not slaved together as in...

    Configuration of the SD220 has been simplified as compared to the SD200. It is no longer necessary to remove the cover to change options. These changes include: 1. The DIP switches, now eight per channel instead of four per unit, are accessible through a window on the front panel.
