1 Intended use

The GLMU 200 MP is a transmitter for measuring conductivity or other units based on conductivity measur­ing in liquids.
The measurement is performed by means of alternating current flow between the poles of the measurement
cell, being in direct contact with the liquid.
The measurement is displayed via analogue standard signal output and a liquid crystal display.
The 4-20 mA model is supplied only by the current loop, the 0-.. V model required a separate power supply.
The configuration of the various parameters has to be checked prior to use.

2 General Advice

Read through this document attentively and make yourself familiar to the operation of the device before you
use it. Keep this document in a ready-to-hand way in order to be able to look up in the case of doubt.

3 Safety Requirements

This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures
and special safety advises given in this manual will be adhered to when using the device.

1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to
any other climatic conditions than those stated under "Specification".
If the device is transported from a cold to a warm environment condensation may cause in a failure of the
function. In such a case make sure the device temperature has adjusted to the ambient temperature be­fore trying a new start-up.

2. General instructions and safety regulations for electric, light and heavy current plants, including domestic
safety regulations (e.g. VDE), have to be observed.

3. If device is to be connected to other devices (e.g. via PC) the circuitry has to be designed most carefully.
Internal connection in third party devices (e.g. connection GND and earth) may result in not-permissible
voltages impairing or destroying the device or another device connected.

4. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be
marked accordingly to avoid re-starting.

Operator safety may be a risk if:

- there is visible damage to the device

- the device is not working as specified

- the device has been stored under unsuitable conditions for a longer time
In case of doubt, please return device to manufacturer for repair or maintenance.

5. Warning:

Do not use these products as safety or emergency stop devices, or in any other application where failure of
the product could result in personal injury or material damage. Failure to comply with these instructions
could result in death or serious injury and material damage.

4 Disposal instructions

This device must not be disposed as ‘residual waste’.
To dispose this device, please send it directly to us (adequately stamped).
We will dispose it appropriately and environmentally friendly.

5 Calibration Services

Factory calibration certificate - DKD certificate - official certifications:
If the measuring instrument is supposed to receive a factory calibration certificate, it has to be sent to the
manufacturer.
Just the manufacturer can check the factory settings and correct them if necessary.

6 Installation

Dimensions

General elbow-type plug installation instructions

To mount the connection cable (2-, or 3-wire depending on type of
device) the elbow-type plug screw has to be loosened and the cou­pling insert has to be removed by means of a screw driver at the
position indicated (arrow).
Pull out connection cable through glanding and connect to the
loose coupling insert as described in the wiring diagram.
Replace loose coupling insert onto the pins at the transmitter hous­ing and turn cover cap with cable outlet in the direction desired untill
it snaps on (4 different starting positions at 90° intervals).
Re-tighten the screw at the angle plug.

6.1 Assignment of elbow-type plug

4-20 mA (2-wire-connection). voltage (3-wire connection).

1 = supply +
2 = GND / signal

1 = signal +
3 = supply voltage +Uv

(4) = supply voltage -Uv

The type current or voltage output is set by works and cannot be changed

6.3 Usage of Unit-Labels

As the transmitter is a multiple purpose device, many different display units are possi­ble, e.g. µS/cm, kOhm·cm.
Therefore unit-labels (within scope of supply) can be shoved between the case cover
and the front foil behind the transparent unit-window.
To replace a label, unscrew the cover, pull out the old label (if present) and shove in the
new one.
The unit depends on the settings of the Cell-constant, the function and the measuring range!
