  • Page 3: Product Overview

    The DC1 controller is for use with Hawker sensing electrodes for detecting conducting liquids. The DC1 can be used with two electrodes to provide high or low level alarm or with three electrodes to provide control between two levels such as for pump control.

    4. Try to keep each controller P1 and P2 electrodes close together; do not mount them in the conductive path of other controllers’ electrodes. Application 3: Multiple controllers with separate ‘G’ electrodes in the same vessel. Configure the controllers as master devices switching DIL switch 4 to the lower position.

  • Page 10: General Electrode Considerations

    General Electrode Considerations Try to keep each individual controller’s electrodes together as a set i.e. do not locate an electrode of one controller in-between the electrodes of another. Always place the G in the centre of the active electrodes to shorten the conductive paths.
