Page 12: Overview

Overview The information such as characteristics, features and part names are described in this section. Introduction Pump structure & Operating principle The EWN series is a diaphragm metering pump which consists of a pump head, drive unit and control unit. A diaphragm is directly driven by electromag- netic force.
Page 13
● Auto degassing system Discharge port Air vent port Automatic air vent valve body LOCK Air vent valve Pump head valve Pump head Suction port • Once air is entrained through the suction port, the working pressure difference between the pump head valve and the air vent valve separates entrained air from liquid.
Page 14: Features

Features ● Multivoltage operation The EWN-R series is a multivoltage type (100-240VAC) and can be selected without concern for local power voltage. ● High turndown ratio Digitally-controlled stroke rate range is 0.1-100%. The stroke length shifts for a fine flow adjustment. ●…
Page 15
Multiplier programming (See page 51) 1-9999 shots can be programmed to one pulse signal. *In the EXT operation, the pump runs at the manual operation stroke rate. *The pump makes one shot per pulse when the multiplier is programmed to 1. Example) When the multiplier is programmed to 5, the pump makes five shots per signal.
Page 16
ANA. R (analogue rigid) programming (See page 57) The pump increases/decreases a flow rate in proportion to 0-20mA. Four (4- 20, 20-4, 0-20, 20-0) programs are provided. In «4-20» or «20-4» program a disconnection sensor works to stop the pump as a current value falls below 4mA («DISCN»…

Page 30: Wiring

Wiring Wiring for a power voltage and an external signal. Observe the following points during wiring work. • Electrical work should be performed by a qualified operator. Always ob- serve applicable codes or regulations. • Observe the rated voltage range, or the electrical circuit in the control unit may fail.
Page 31
NOTE • Do not share a power source with a high power device which may generate surge voltage. Otherwise an electronic circuit may fail. The noise caused by an inverter also affects the circuit. • Energize the pump with a power voltage via a mechanical relay or switch. Do not fluctuate the voltage, or CPU may malfunction.
Page 32: Signal Wire Connection

Precautions for ON-OFF control by a mechanical relay The control unit is equipped with CPU. Always start/stop the pump by the STOP signal for ON-OFF control. Try not to turn on and off the main power. Otherwise, observe the following points. •…
Page 33
NOTE • Do not lay on these signal cables in parallel with a power cable or combine them in a concentric cable (ex. 5 wires cable). Otherwise noise is generated through the cables due to induction effect and it results in malfunction or failure. •…
Page 34: Connections

■ Connections • Level sensor The EWN have two stage level sensor, the Pre-STOP and STOP alarms. Con- nect the pre-alarm signal to the Pre-STOP and the alarm signal to the STOP. The pre-alarm functions just to notify a low liquid level by flashing the LED orange while the pump is running.
Page 35
• Pulse signal In the EXT (MULT or DIV) mode, the pump runs along with a multiplier or a divisor as receiving the pulse signal. • When using an open collector… Pay attention to polarity. Pulse is plus(+), and COM1 is minus(-). (Maximum 2.3mA at 12V) •…

Please pay attention to the information associated with the symbols.
Page 7: Warning

WARNING Turn off power before service Risk of electrical shock. Be sure to turn off power to stop the pump and related devices before service is performed. Electrical shock Stop operation If you notice any abnormal or dangerous conditions, suspend op- eration immediately and inspect/solve problems.
Page 8: Caution

CAUTION Qualified personnel only The pump should be handled or operated by qualified personnel with a full understanding of the pump. Any person not familiar with the prod- uct should not take part in the operation or maintenance of the pump. Requirement Use specified power only Do not apply power other than that specified on the nameplate.
Page 9
Do not use the pump in a wet location The pump is not waterproof. Use of the pump in wet or extremely humid locations could lead to electric shock or short circuit. Prohibited Grounding Risk of electrical shock! Always properly ground the pump. Con- form to local electric codes.
Page 10: Precautions For Use

Precautions for use • Electrical work should be performed by a qualified electri- cian. Otherwise, personal injury or property damage could result. Caution • Do not install the pump: –In a flammable atmosphere. –In a dusty/humid place. –In direct sunlight or wind & rain. –…
Page 11
• Use care handling the pump. Do not drop. An impact may affect pump performance. Do not use a pump that has been damaged to avoid the risk of electrical damage or shock. • The pump has a rating of IP65 equivalent, but is not water- proof.
Page 12: Overview

Overview Pump characteristics, features and part names are described in this section. Introduction Pump structure & Operating principle The EJ series is a diaphragm metering pump which consists of a pump head and a drive unit with a built-in controller. A diaphragm is directly driven by elec- tromagnetic force.
Page 13: Features

Features ● Multivoltage operation The EJ series is a multivoltage type (100-240VAC) and can be selected with- out local power limitations. ● High turndown ratio Digitally-controlled spm range is 1-360spm. ● IP rating of 65 equivalent This pump is not waterproof. Protect the pump with a cover when installing it out of doors.

Connect tubes into the inlet and outlet. Outlet Tube Inlet Tube Connect an air bleed tube into the Air vent port air vent port. Route back the other tube end to a Air bleed tube supply tank or a container. Determine an air vent port direction.
Page 21: Check Valve Mounting

Check valve mounting Install an optional check valve to the EJ for the prevention of a back flow, siphon and overfeeding. In the following cases be sure the check valve is installed. • A suction side liquid level is higher than a discharge side or an injection point at atmospheric pressure.
Page 22
Mount a check valve at the discharge tube end. * The CAN check valve has the R1/2 and R3/8 thread connections as well as an O.D.9mm tube connection. Cut off an unused part and adjust the connection length as necessary. CAN check valve R1/2 O.D.9mm…
Page 23: Wiring

Wiring Wiring for a power voltage, earthing and an external signal. Observe the following points during wiring work. • Electrical work should be performed by a qualified electrician. Always observe local electric codes. • Observe the rated voltage range, or the electrical circuit in the control unit may fail.
Page 24
NOTE • Do not share a power source with a high power device which may generate surge voltage. Otherwise an electronic circuit may fail. The noise caused by an inverter also affects the circuit. • Energize the pump with a power voltage via a mechanical relay or switch. Do not fluctuate the voltage, or CPU may malfunction.
Page 25
Precautions for ON-OFF control by a mechanical relay This pump is equipped with CPU. Observe the following points when ON- OFF control is performed: • Do not turn ON/OFF power voltage more than six times per hour. • When using a mechanical relay for ON-OFF operation, its contact capac- ity should be 5A or more.
