wIrIng the puMp or ValVe outputs
•
If the SQ-Elite-8T is configured to operate Stage Pumps or Valves. They, must be wired to the
stage output after the highest stage for that unit. That is, the low stage for the first unit must be
connected to A and the higher stage of the same unit must be connected to Stage B. The unit
valve or pump for the same unit must be connected to Stage C.
connectIng to the sq-elIte-ext panels and 4-20Ma eMs Interface
•
The SQ-Elite is equipped with a phone socket (RS485) to connect to the SQ-Elite-EXT Extension panels or the 4-20mA EMS
Interface using the provided 6-pin phone cable.
•
Each SQ-Elite-EXT Extension has two RS485 communication ports. Use one to connect to the SQ-Elite. Use the other port to
connect to the second extension or the 4-20mA EMS Interface.
•
Additional compatible devices can utilize the second RS485 connection on the second SQ-Elite-EXT Extension. An example
would be to use the 4-20mA EMS Interface (HT# 926741-00) to provide a 4-20mA set point signal to the SQ-Elite.
selectIng the sq-elIte-ext panel letter
•
The SQ-Elite is capable of communicating to two SQ-Elite-EXT Extensions. However, each
extension must be identified as either A or B using the switch on each extension to avoid having
communication problem.
•
Extension A (Switch is set to "A") will operate stages "I" through "P". While Extension B
(Switch is set to "B") will operate stages "Q" through "X".
