2611 - Alternating Controller

Hot Features:

·Alternate two loads or lock sequence with lead select switch

·Sequence on - Simultaneous off (S.O.S.O.) operation

·Works with 3 switches - Stop, Lead & Lag

·Control switch fault detection

·Replaces multiple components - saving space and labor

Model 2611 Alternating Controllers are microprocessor-based designs for use where two loads are required to alternate for equal run time. LED indicators show status of the units three contact switch inputs and two load outputs. The controllers lead select switch allows loads to alternate normally in the center position, or disable automatic sequencing and lock in a 1-2 or 2-1 sequence.

When a Stop, Lead, or Lag switch closes - corresponding LED atop the Model 2611 illuminates.

When the Stop switch and Lead switch closes, Load 1 or Load 2 will come on and the corresponding green LED will illuminate. If fluid levels continue to rise and the Lag switch closes, the 2nd load will energize. Loads remain energized until the Stop switch opens or a fault condition is detected. See Typical Pump Down Application - SOSO Operation (page 3 pdf.) for details.
