Fire, Explosion, and Electric Shock Hazard

Improper grounding, poor air ventilation, open flames, or sparks can cause a hazardous

condition and resulting fire or explosion and serious injury.

•Ground the equipment.

•Proper grounding dissipates static electricity generated in the equipment.

•This equipment is not intended for intrinsically safe areas.

•Keep the dispense area free of debris, including solvent, rags, and gasoline.

•If there is any static sparking or you feel an electric shock while using the equipment,

stop operating immediately. Do not use the equipment until you have identified and

corrected the problem.

•Make sure all electrical work is performed only by a qualified electrician.

•Have any checks, installation or service to electrical equipment performed by a

qualified electrician only.

•Make sure all electrical equipment is installed and operated in compliance with local

and applicable codes.

•Make sure power is disconnected when servicing and repairing equipment.

•Keep liquids away from the electrical components.

•Disconnect electrical power at the main switch before servicing the equipment.

•Never exceed maximum wattage of the supply unit.

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 is initiated by a 120 volt signal. The pump cycle may be initiated by some other piece of

equipment such as a timer or a pH controller. An isolation relay may be required in some installations. Always

follow local and applicable electrical codes. 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 to use the proper

strain relief, wire type and wire size can cause

damage to internal components or personal

injury.

There are three connections on the 120V input

signal terminal block (see Fig. 1). The two

right-hand connections are for line and neutral

wires respectively. The left-hand connection is

for a true earth ground.

Fire, Explosion, and Electric Shock

Hazard

To reduce the risk of fire, explosion, or electric

shock:

•The power source conduit is not an

adequate grounding for the system. The

unit must be grounded to a true earth

ground.

•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.

Pneumatic Connections

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. The exhaust is silenced with a muffler. Do not exceed 120 psi at the air inlet to the

unit. Refer to your pump owner’s manual for the maximum air pressure limit of the pump.

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.

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. The pump cycle rate is measured in Cycles Per Minute (CPM), i.e. the number of times the pump

performs a pump cycle in one minute. 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. This timer is adjustable between 10 and 200 cpm.

Turning the screw clockwise will decrease the cycle rate

of the pump. 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.

9309004

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. Shut off electrical supply before making

adjustments.

Operation Procedures

The controller and pump are now ready for operation. The pump will cycle at the preset rate any time a 120 Volt

signal is supplied to the controller.

Troubleshooting

The following is a list of possible problems and their causes.

Problem Possible Cause & Remedy

No operation at all 1. No power to the CycleFlo – check power source to unit.

2. Damaged cycle rate adjustment relay – replace.

3. No or low air supply – check air supply to make sure there is

sufficient pressure and air available.

4. Bad wire connections – turn off power and check wire connections

from time delay relay to make sure they are all connected and

seated properly.

5. Bad solenoid valve(s) – turn off air supply and listen for ‘clicking’ on

solenoid valves; replace valves if no ‘clicking’ is audible.

Pump only operates on one side /

diaphragm. 1. Bad solenoid valve. Turn off and replace.

2. Damaged cycle rate adjustment relay.
