Product Details

• 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, 1 alarm and 2 load outputs
• H-O-A (hand off automatic) switches, a lead select switch and a test/clear button are provided for manual control
• ARM Series reduces the number of components required for this application by combining many functions into 1 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
• 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
