The Smart Interrupter provides a means of placing
a characteristic signature on pipes by interrupting
the flow of cathodic protection (CP) current.
The Smart Interrupter is specifically designed for use with
the Radiodetection Stray Current Mapper (SCM) and
Pipeline Current Mapper (PCM+) but can also be used as a
stand-alone interrupter.

  • Page 5: Pulse Mode

    Pulse Mode In pulse mode the Smart Interrupter puts a simple on/off pulse onto the line and assists in signal identification when using more than one Smart Interrupter at the same time. If using more than one Smart Interrupter make the pulse On/ Off times different for each unit.

  • Page 6: Timer Mode

    Previous Settings To retrieve any one of the last ten settings in pulse mode, press and hold down the pulse button and at the same time press either the left or right arrow button. The screen will cycle through the last ten settings, showing the number of each setting (1 is the most recent).
  • Page 7 Master-Slave Synchronization using the synchronization lead Note: This method is not recommended when using the Smart Interrupter with the SCM. When using several Smart Interrupters at the same time they must be time synchronized with each other to ensure signal compatibility.
  • Page 8 master synchronized Unit, an ‘m’ is displayed on the screen. If you attempt to change a setting that would make the master/slave patterns incompatible, the Smart Interrupter emits a 2-second tone and the following screen is displayed. Pressing the OK button will allow the settings to be changed but with no further warnings being displayed, and synchronization may be lost.
