  • Page 3: Introduction

    1. INTRODUCTION VA/V3 water sampler is designed as an all-purpose unit capable of sampling both contamined and clean water in all kind of industries. 1.1 CONSTRUCTION VA/V3 water sampler has a robust, splashproof plastic casing with a transparent front cover.

  • Page 4: Installation

    2. INSTALLATION 2.1 CASING VA/V3 is mounted in a robust splashproof casing made of glassfiber reinforced polyester with transparent polycarbonate front cover. The protection class is IP 65. 2.1.1 ( mm ) 2.2 MOUNTING The water sampler shall be mounted vertically using four screws (∅ 7 - 9 mm). The mounting is done through the four mounting brackets at the rear side of the sampler.

    2.3.2 Alarm output Alarm output for connection to an external alarm unit. Max load: 24 VDC 2.3.3 Connection of a potential free contact (level sensor etc) Connection is made through the black and black wire on the external control cable. 2.4 CHECKING THE CONNECTIONS Before the main supply is turned on, please check that the connections are correct made (both mechanical and electrical).

  • Page 6: Functions

    When water is present in the vacuum tube the sampler immediately turns off all active functions and empties the sample bottle. Error code E-08 is shown on the display. In this case, contact Elmacron AB. INTERNAL 1 - 36 samples/h...

    3.3.3 ANALOG Flow related sampling 0/4 - 20 mA. The sampler is controlled by a mA - signal, where mA is proportional to the flow. Accumulating of the flow is performed and when accumulated flow = pre-set interval, the sampler takes a sample.

    The interval is set to 3,6/3 = 1,2 m between samples. Ex.3 Max. flow 3,6 m Number of samples 6 samples/h The interval is set to 3,6/6 = 0,6 m between samples. Because the interval range is 1.000 - 9999 m between samples, you have to multiply both the flow and the interval with the same factor.

  • Page 11: Sampling Sequence

    Sampling is carried out after settings of the actual parameters. VA/V3 restarts automatically according to the latest settings when turning the main supply on. 5.1 SAMPLING SEQUENCE During sampling sequence, you can follow the steps in the sampling sequence at the display.
