AQUEOUS™ Control System to include:

Human Machine Interface (HMI)
•	NEMA 4 (4” or 7” or 15”) Color Touch Screen HMI with Live indication of all connected sensors and password protection for access to applicable configuration settings.
•	Alarm handling and time/date log for start, acknowledge, and released alarm statuses.
•	Oscilloscopes for tuning all analog output functions. 
•	Indication for Run, Idle, Fault per pump with Cycle Timer and Totalized Runtime.
•	NEMA 4X clear plastic cover with UV protection for outdoor and food grade environments. 

Programmable Logic Controller (PLC) with the following functionality: 
•	Alarms and Safeties
o	High-High, High, Low, Low-Low and Signal Lost alarms for Tank Level, Temperature, and Pressure
o	Low level cutoff, High temperature cutoff, Low temperature cutoff and High pressure cutoff for pumps 
o	Fault alarm per pump
•	Digital outputs for:
o	Pump controls for up to 8 pumps in up to 3 unique groups. (Specify number of pumps, purpose, alternation type, and staging with lead pump behavior per group.)
•	e.g., 2 Condensate return pumps to alternate on run cycles and stage on tank level with lead pump on/off
•	e.g., 2 Vacuum pumps to alternate on run cycles and stage on return line vacuum with lead pump on/off 
•	e.g., 4 Boiler feed pumps to alternate on run time and stage on discharge pressure with lead pump continuous 
o	Field Programmable Relay contacts. (15 max. Specify dry contacts in panel or specific functions with ancillary equipment.)
•	e.g., Solenoid makeup energized on low tank level
•	e.g., Steam-tight solenoid overflow drainer energized on high tank level 
•	e.g., Blowdown valve energized on time cycles
•	e.g., Pump recirculation solenoid to prevent lead pump deadhead
•	e.g., End switch contacts for chemical feed system
•	e.g., Steam injection solenoid energized on low tank temperature
•	e.g., Cooling water solenoid energized on high tank temperature
•	Analog outputs for: (12 max. Include all that apply. Specifying feedback loop helps clarify specs but not always necessary.)
o	Up to 2 electric modulated (transfer or makeup) fill valves with PID to maintain tank level 
o	Up to 3 electric modulated steam injectors with PID to maintain tank (temperature or pressure)
o	Up to 3 VFD speed references (“With a linear response to Steam Header Pressure”…  See chart below for common feedback loops)
•	Pumps in the same staging sequence to operate on the same speed reference 
o	Modulated Vent Valve to reduce oxygen vent capacity based on live deaeration load
o	Additional analog outputs not yet mentioned (Contact factory for assistance)
•	Building management integration via BACnet IP or BACnet MS/TP and/or Modbus TCP and Modbus RTU
o	Live value of all analog and digital inputs; includes various individual alarms
o	Live value and remote override capability for all analog and digital outputs
o	BTL Listing and Protocol Implementation Conformance Statement (PICS) required

Sensor Components to be monitored by PLC (Include all that apply)
•	Tank Level Sensor
•	Tank Temperature Sensor
•	Tank Pressure Sensor
•	Pump Discharge Sensor (Per Pump Group)
•	System Pressure Sensor mounted in the (Steam Header for boiler feed or Condensate return line for vacuum pumps) (Per Pump Group)
•	Up to 2 Flowmeters mounted in the (Specify location and pipe size) (with or without temperature sensing)
•	Up to 11 additional sensors, not yet mentioned, for any measurement with a 4-20mA output. (Specify manufacturer to supply, by others, or dry contacts) 

Panel Components
•	Control Circuit Disconnect
•	Audible alarm bell with silence button
•	Auto-Off-Continuous selector switch(es) per pump. Auto position to operate according to PLC. Continuous position to run pumps at full speed in case of PLC service or failure. (Auto-Off-Hand or Auto-Off-Test labels also available with same functionality)
•	Entire unit to be UL Listed
•	Backup Mechanical Low Water Cutoff Switch
•	Single Point Power
•	Main Power Disconnect or Emergency Stop

The NEMA 4X Shipco® Level and Temperature Transmitter is required in lieu of all float switches or mechanical alternators for pump control and alarms except on Deaerators and Surge Tanks.

For Deaerators and Surge Tanks, a NEMA 4X differential pressure (DP) level and temperature transmitter is required in lieu of float switches for pump control, alarm points, level control and/or cutoff. One Emergency low water float switch is required.
