The Poseidon cycle controller is a stand alone, fully independent water softener and filter controller. It is housed in a NEMA 4X fiberglass enclosure mounted either directly to the multiport valve or to the adjacent face piping. The cycle controller has the following major components:

Mitsubishi Alpha Programmable Relay and four to six ASCO Red Hat Solenoid Valves

The Alpha relay and the ASCO valves are all 120 VAC and the solenoids are mounted directly to the fiberglass enclosure. Tubing is run from the solenoids to each of the diaphragm valves for control. The ASCO solenoid valves are universal three way valves and are all de-energized in the service position. The Poseidon cycle controller can initiate a regeneration sequence from any of the following sources:

	120 VAC start signal from a Badger AR or AR/e, or a 120 VAC signal from any other source, such as a hardness monitor or external batch controller.
	Internally based on a gallon set point with a signal from a Badger 120 VAC pulse transmitter mounted directly to a meter
	Internally, based purely on time clock
	Internally, based on elapsed time in service in the event of a failure in the external meter or other input source

The Poseidon control is shipped ready to regenerate based on any of these conditions. If you have a time clock system and want to add meter initiated or pulse transmitter regeneration, you simply hook the wires to the appropriate input terminals and select your batch size.

The Poseidon cycle controller has many advantages over a 'traditional' cycle controller. Some of these are as follows:

	Fully electronic, no electromechanical parts
	The capability to reclaim brine
	On an alternating system, the Poseidon control is programmed to pre-flush the standby softener prior to placing it in service
	Up to two extra outputs are available for remote functions, such as turning on brine pumps
	EEProm memory in the Alpha relay, so even extended power failures are not a problem
	Additional EEProm memory cassettes are available for long term program back up or running an alternate program

If your softener control system includes high speed counters (Signet Flow Sensors) you must add a batch controller to the system. the batch controller can handle up to four softeners simultaneously. The controller is designed around a Mitsubishi FX1S PLC with relay outputs. Power supply to the controller is 120 VAC; the PLC has an internal 24 VDC power supply to provide power to the flow sensors and PLC inputs from the Poseidon controllers. The PLC uses relay outputs to provide a 120 VAC signal as an input to the Poseidon cycle controllers. The batch controller is typically mounted to face piping.

The batch controller performs the following functions:

	Accepts input signals from up to four flow sensors
	Performs batch control functions for each of the resin tanks
	Provides progressive flow control to sequence the number of softeners on line based on a user selectable set point
	In multiple tank system the batch controller automatically corrects the sequence of operations if one of the softeners is disabled in the program
	A triple system automatically corrects itself to a twin system when a softener is disabled. The twin continues to operate automatically until the problem is corrected and the system returns to a triple again

The batch controller sends an output signal to each of the resin tanks to initiate a regeneration at the end of the batch. It also sends an output signal to each of the softeners to open the outlet service valve of a standby softener when the flow set point is reached. Each Poseidon control sends a signal back to the batch controller when in regeneration. This input resets the batch, if necessary, and sequences the 'lead unit' logic.

Communicatins between the batch contrller and the Poseidon cycle controllers is typically handled with multiconductor shielded cable. Each cycle controller connects to the batch controller with one 24 VDC cable and one 120 VAC cable.
