Lockout function: The controller shall include a lockout to prevent unauthorized personnel from altering program r data. Regeneration override: The controller shall include a function to direct pre-programmed regeneration after a user determined period of time (hours or 24 hour intervals) without an input signal from another regeneration initiation device. Alarm status indicator: The controller shall monitor operation of internal functions. if a fault Is Identified, the need for operator intervention will be signaled visually within the controller display. Two Auxiliary Outputs: Two Auxiliary Outputs shall be integral to the controller circuit board, Each Output shall be capable of being programmed to provide power to a "Normally Open" or "Normally Closed" contact (user choice). These 24VAC outputs shall be used only for the purpose of energizing a relay coil. Flow rate indication: The controller shall be capable of indicating the flow rate of the treated water. Totalizer: The controller shall include a totalizer function and a display capacity to 99,999,999 units before resetting to zero. The totalizer value shall be displayed through the controller display during operation. The controller shall have the availability to be wall- or remote -mounted for greater accessibility. 4.5.3 Flow Sensor(s) Each softener will Include a turbine -type Hall Effect flow sensor. The sensor shall be integral to the control valve. A cable shall be provided for direct connection to the system controller. The flow sensor package provided shall be functional within the flow range of 1.5 to 180.0 gpm. The flow sensor shall have an accuracy of +/- 2% over the full range 4.5.4 Aqua -Sensor® probe A patented Aqua-Sensoro control probe will be inserted into the resin bed and will sense the need for regeneration based on an electrical imbalance within the resin bed and will signal the circuit board to initiate regeneration after a continuous 6 minute Imbalance. The system will compensate for variations in water hardness and temperature and will require no field adjustments when operated within the normal temperature range of the softener. The controller shall be capable of being programmed in the field without additional interface devices. The Aqua -Sensor will also be capable of determining when the brine solution is rinsed from the resin bed during the Brine Draw /Slow Rinse cycle, triggering the control to move to Fast Rinse cycle. 4.6 I XCHANGE RESIN The !on exchange resin shall be virgin high capacity "standard mesh" of sulfonated polystyrene type stable over the entire pH range with good resistance to bead fracture from attrition or osmotic shock. Each cubic foot of resin will be capable of removing 30000.0 grains of hardness as calcium carbonate when regenerated with 15.0 pounds of salt. The resin shall be solid, of the proper particle size of 16x40 mesh, U.S, standard screen and will contain no agglomerates, shells, plates or other shapes that might interfere with the normal function of the water softener, The resin shall be manufactured to comply with the food additive regulation 21 CFR 173.25 as set forth by the USFDA. The system shall include 5 cubic feet of exchange resin per vessel 4.7 BRINE SYSTEM Provide a complete brine system consisting of a plastic tank, cover, salt platform, brine well, an automatic brine valve and ail necessary fittings for operation with the water softening system. The system shall consist of a combined brine measuring and salt storage tank with salt platform. The brine tank will be equipped with a float operated non -corrosive field serviceable brine float valve for automatic control of brine withdrawal and fresh water refill. The brine valve will automatically open to admit brine to the resin tank during eduction and close automatically providing positive shut-off to prevent air from entering the system. The brine valve will also regulate the flow of Page 4 of 5
