SPECIFICATIONS 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 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. TWO PUMP SEQUENCING: Evenly distributes run time by automati- cally alternating lead and lag load designations when the off control switch input opens. UL913 INTRINSICALLY SAFE: Control switch inputs are low voltage/ low current and are electronically isolated from the control voltage and load alarm contacts. H-O-A Switches: Hand-Off-Automatic switches allow for manual operation. LEAD SELECT SWITCH: Disables the automatic sequencing function and allows loads to be locked into the 2-1 or 1-2 sequence. CONTROL SWITCH FAULT DETECTION: Unit detects open and shorted control switch failures. TEST/CLEAR SWITCH: Verifies function and resets the control switch fault detection algorithm. ALARM OUTPUT: Alarm contacts close when a control switch fails or the system’s capacity is exceeded. INRUSH CURRENT DELAY: Reduces line sags by preventing both loads from energizing simultaneously. VERSATILE MOUNTING: Two (2) mounting configurations 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.
