Stager Controller 503Multiple valve controller IntroductionStager Controller functions: Password setting Calendar Regeneration stage and regeneration time indication JMA can be initiated manually or through remote control. Timer initiation and interval initiation are also Stager Controller available. Manual step by step initiation (only for system commissioning) Reset function Stages (1-8) and stage duration (5-9999 Sec) settings System working stage indication (Service or regeneration stage indication) Data protection after power cut: settings and data can be stored for 3 years. Waterproof and rotproof enclosure Stager Controllerworking principle: The stager may be manually operated or driven by an electric motor that operated through an adjustable timer or flowmeter program. The stager functions by opening and closing its ports,Website: , singly or in combination, in a sequence that fit the need of the system. The  positions  in the sequence correspond to the number of  stager in the process (See chart 1). The port that are opened allow the pressurized fluid to flow to and operate some diaphragm valves, while venting other valves allowing them to return to their normal positions. The stagers can use either hydraulic or pneumatic control fluid. Continuous electrical power is not required to maintain the positions of the valves such as in a solenoid operated system. Greatly avoid the system breakdown because of power failure. All types of complex application can be controlled by Stager Controller system through correct design and combination of the stagers.Next is Typical Circuit Application for JMA 502STAGER POSITIONSOFTENER FUNCTIONVALVES OPEN4SERVICE1, 21BACKWASH3, 4 (2A)2BRINE5, 2 (2A)3FAST RINSE6, 1 (2A)JMA Stager Controller specifications:Automatic restoration function Waterproof enclosure (waterproof and shockproof) Power supply: 220VAC/50HZ Timer initiation setting: any time of the day 7 days one week 8 stages available with duration from 5 to 9999 seconds for each stage Manually initiation Service/regeneration Light indication Auxiliary signal output Stager Controller Technical figures: Electrical supply: 220VAC/50HZ, 10W Remote control signal: At least 2 seconds/dry contactor Pressure port size: 1/8 G thread Control fluid: hydraulic or pneumatic (100 filter is recommended for the system) Control fluid pressure: 0.2~0.8MPa Temperature: 4~60  Enclosure size: 270 mm X 170 mm X 105 mm Stager Controller Applications:Item IDTypical applicationStage programJMA 501FilterService backwash rinseJMA 502Co-current regeneration softenerService backwash brine + slow wash rinseJMA 503Filterservice backwashJMA 505Counter-current regeneration softenerService backwash brine + slow wash rinseJMA 5063 tanks filterservice 1#backwash 2#backwash 3#backwashJMA 5074 tanks filterservice 1#backwash   4#backwashJMA 5085 tanks filterservice 1#backwash    5#backwashJMA 5232 tanks filter (1service 1 stand by )1#service 1#backwsh 2#service 2#backwashJMA 524Co-current regeneration water softenerservice backwash brine slow wash rinse refillJMA 525Co-current regeneration water softenerservice backwash brine slow wash rinseJMA 526Co-current regeneration water softenerservice backwash brine rinse refillJMA 5272 tanks parallel filterservice backwash 1 rinse 1 backwash 2 rinse 2JMA 528Filterservice drain air flush backwash rinseJMA 529Brine recycle water softenerservice backwash brine brine+slow wash brine recycle  rinseJMA 5306 tanks filterservice 1#backwash    6#backwashJMA 5317tanks filterservice 1#backwash    7#backwash
