  • Page 17: Before Use

    1. Before Use Operators and maintenance service staff must read the instruction manual thoroughly before using the products．Do not operate the pump system unless all of the contents in the manual are completely understood． Caution. Turn off the power supply． ． ． ． Working without disconnecting the power supply may cause an electrical shock.

  • Page 18: Location

    2. Location Choose a location for the pump which is clean, dry, close to an electrical outlet, and allows convenient access to stroke length control, frequency control, and tubing connections. Avoid areas where ambient temperature exceeds 40℃ or falls below 0℃, or where the pump or tubing would be exposed to direct sunlight.

  • Page 19: Discharge Tubing

    4. Discharge tubing The discharge tubing run is less critical and can be any length required to reach the application point. Avoid sharp bends or kinks in the tubing and protect the tubing from sharp edges that could chafe or cut it.

  • Page 21: Priming

    1. Priming Caution. Do not operate the pump with discharge-side valve completely closed. Operating the pump with discharge-side valve fully closed may lead to liquid leakage or pipe rupture. Do not run pump dry. Dry operation of the pump over a long time (longer than 30 minutes) causes the pump to overheat and the pump unit (pump head, valve guide etc.) to become deformed or the pump head attachment to become loose, which may result in liquid leakage trouble.

  • Page 22: Adjustment

    2. Adjustment The pump will operate best with the stroke length at 100%. It is recommended to get required flow rate by adjusting frequency control. Example: Model EH-E30VC has maximum output of 340 　 　 　 　 ml/min. Required output is 255 ml/min. 255÷340 = 0.75 or 75 %.

    4.External Control 4.4 Analog Mode 4.4Analog Mode. In analog mode the pump will accept a milliamp signal and produce a pump speed proportional to the signal level received. Signal ranges of 4-20, 0-20,20-4 or 20-0 can be selected. 1.Connecting an analog signal device Disconnect AC power to the pump.
  • Page 29 STOP Function The EH-E series pump also includes a STOP function which allows an external signal to stop the operation of the pump. A switch or solid state device capable of switching 5 VDC at 2 mA can be connected to terminals 6 (positive) and 8 (negative) of the terminal block.
