Read all instruction manuals, tags, and labels before operating the equipment. Other than for installation purposes do not alter or modify this equipment. [. . . ] Never exceed maximum wattage of the supply unit. · · · · · · · 4 309004 General Description The CycleFlo II is a pneumatic pump controller that allows precise control over the cycle rate of the pump and therefor the flow rate. The pump cycle may be initiated by some other piece of equipment such as a timer or a pH controller. The CycleFlo II will halt the pump cycle whenever the 120 volt signal is removed. Installation Electrical Connections An access hole with a strain relief installed has been provided for the external power connection. Due to the unique requirements of each installation, access holes have not been provided for the other optional external wiring connections such as the external air supply valve signal. Have a qualified electrician determine the proper strain relief, wire type, and wire size for your particular application. When positioning or adding access holes, be careful not to damage any internal components. Failure Fire, Explosion, and Electric Shock to use the proper strain relief, wire type and wire size can cause damage to internal components Hazard or personal injury. To reduce the risk of fire, explosion, or electric shock: There are three connections on the 120V input · The power source conduit is not an signal terminal block (see Fig. The hand connections are for line and neutral wires unit must be grounded to a true earth respectively. · A qualified electrician must complete all grounding and wiring connections and check the resistance. · Refer to your local code for the requirements for a "true earth ground" in your area. 5 309004 Fig. 1 - Electrical Diagrams Cycle Rate Adjustment Relay 120 Volt Signal Solenoid Valves Pneumatic Connections 6 309004 The integrated air valves, have a common air inlet (1/4" NPT) port and two outlet ports A and B (1/4" Tube) toward the front of the unit. Refer to your pump owner's manual for the maximum air pressure limit of the pump. B Outlet Port Exhaust Muffler Common Air Inlet Strain Relief for Power Supply LIne A Outlet Port Failure to use the following recommended valve can cause damage to the unit and possible personal injury. Follow the pressure relief procedure in the pump manual before moving or servicing the pump. The A and B outlet ports are to be connected to the A and B ports respectively on the Husky 205, or to the two air valve control ports located on the air motors of pumps larger than the Husky 205. On pumps larger than the Husky 205, a three way solenoid valve (Graco Part Number 115606 or equivalent) MUST be installed on the main air supply to the pump. This ensures that pressure is not generated by the pump when the controller is not operating. The same signal used to start the CycleFlo II controller can also control this valve. 7 309004 Setup & Adjustment Cycles Per Minute (CPM) Rate The pump cycle rate is adjustable to accommodate different pump sizes, varying product viscosities and product delivery speed. One pump cycle consists of a momentary pressurization of each one of the two diaphragms. Adjustment The CycleFlo II comes with a cycle rate adjustment relay that can be adjusted using a screwdriver to control the energizing and deenergizing rate of the built-in solenoid valves. Turning the screw counter-clockwise will increase the cycle rate of the pump. Electric Shock Hazard To prevent accidental shock or electrocution disconnect the supply signal before opening the enclosure cover. Cycle rate adjustment screw 8 309004 Operation Priming the Pump Prime the pump by applying a 120 Volt signal to the controller to allow the temporary operation of the pump. This cycle rate may be increased or decreased to facilitate pump priming.
