Details: The ARM Series Alternating Relay is a microprocessor-based controller designed for use in dual load installations to assure equal run time on each load. LED indicators show the status of the unit's five intrinsically safe control switch inputs, one alarm, and two load outputs. H-O-A (Hand-Off-Automatic) switches, a lead select switch, and a test/clear button are provided for manual control. The ARM Series reduces the number of components required for this application by combining many functions into one unit. This series has a two pump sequencing, where it evenly distributes run time by automatically alternating lead and lag load designations when the off control switch input opens. This unit also detects open and shorted control switch failures and verifies function and resets the control switch fault detection algorithm. The alarm contacts close when a control switch fails or the system's capacity is exceeded. This unit also has two mounting configurations that are available. The standard surface mount has top access to controls and indicators and is intended for back panel mounting. The panel mount option is intended for front panel or door cutout access to controls and indicators. Special Controls: ARM-2003 and ARM-2010-Standard operations without the H-O-A switches, ARM-2011-Standard operation without the Control Switch Failure Feature.

Package Dimensions: 6.0 x 6.0 x 5.0 inches
