ARM Integrated Duplex Controller
 

RELAY OVERVIEW

This complete microprocessor based pump controller is designed to assure equal run time for each pump with a lead/lag/alternating control scheme.  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.

UL913 Intrinsically Safe: Control Switch inputs are low voltage/low current and are electronically isolated from the control voltage and load alarm contacts.

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.
