The CD-2R provides redundant control as a backup for a primary control system (e.g. Contegra's Station Master 700 Series).  The CD 2R redundant controller provides backup in case the primary controller failure.  The CD-2R’s outputs are wired in parallel with the primary system’s control contacts.  The CD-2R can use either two float switch On/Off inputs, for differential level control, or a single abnormal level float switch input with a “timed off” function.  The CD-2R’s “timed off” function is a programmable off-delay timer that continues the pump(s) operation after the single ‘abnormal level’ switch has opened.  The off-delay timer is adjustable from 0-10:00 minutes.  The alarm circuit automatically silences and resets following the end of each pumping cycle.
