Ordering

Hardware

  1. Each Sentry-2412 monitors 1 string of 24x12V.
    If a UPS has multiple strings, order one unit for each string.
    By default, Sentry-2412 works for 18 to 24 batteries. For battery string with less than 18 batteries, Sentry unit has to be customized and cannot be changed back by customer.
    Each unit comes with 2 temperature sensors for ambient and pilot temperature.
  2. Unit comes with onboard Ethernet DTU. If wireless DTU is preferred, an activated SIM card (GSM) is needed.
  3. Order O-ring leads, specify 6mm (1/4"), 8mm(5/16") or 10mm(3/8"). 
  4. Order current sensor if needed. Default window size: 15mmx20mm, close loop 300A (peak current 600A). Other size/range and split-core sensor may have longer lead time.
  5. A HMI touch display is recommended for field service. 
  6. Optional 7-conductor 20AWG cable, calculate the length: Sentry unit mounting distance to farest battery x 4.
