Product Description
The controller is of an automatic operation management controller designed for small-scale first-class anti-osmosis water preparation system, which can realize automatic operation of anti- osmosis devices only by adding few electric elements at periphery. It has digital input (DI) ports in five states and four output control ports, and it is a small-scale economical controller.

FS:High-pressure and low-pressure flushing selection
HP:Access terminal for overpressure detection of Booster (high pressure) pump (normally closed, disconnecting in case of overpressure, and short out COM at top right corner when not using)
NW:Detection on low level of original water tank or low pressure of pipeline (use liquid level switch or pressure switch and installation of sampling point)
LP:Access terminal of switch for detecting security filter pressure at back of low-pressure pump(Contact normally open, and closed when up to the pressure as required)
LC: Input terminal of switch for detecting level of pure water tank (normally closed, disconnecting in case of the water full and closed meeting low liquid level)
EC:Whether the control system operates for access terminal for external control(control by remote and panel switch)
COM: Common port for upper acquisition terminal
AC220V: Firewire end for 220V power supply (220V AC powers on); Zero line for power grid
COM: Common point for control relay
IV: Output contact for controlling on and off of water feeding solenoid valve (normally open and passive)
FV: Control contact for on and off of RO flushing solenoid valve (normally open and passive)
LM: Contact for controlling start/stop of booster pump(normally open and passive)
HM: Contact for controlling start/stop of low-pressure water pump (normally open and passive)
All the above control ports are terminals of dry contact of relay(without power distribution), sharing COM common terminal.
