Mounting distance: 50 x 70mm, max. shaft diameter of mounting screws is 4 mm. Electrical connection: elbow-type plug conforming to DIN 43650 (IP65), max. wire cross section: 1.5 mm², wire/cable diameter from 4.5 to 7 mm EMC: In accordance with EN61326 +A1 +A2 (appendix A, class B), additional errors: < 1% FS. When connecting long leads adequate measures against voltage surges have to be taken. The electrode connections have to be protected sufficiently against ESD pulses, if the device is used in areas with risk of ESD. GREISINGER electronic GmbH T14.0.0X.6C-02 User’s Manual GLMU 200 MP page 2 of 8 2 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 product 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. 3 Installation 3.1 Design types, dimension T14.0.0X.6C-02 User’s Manual GLMU 200 MP page 3 of 8 3.2 General installation instructions To mount the connection cable (2-, 3-, or 4-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 PG glanding and connect to the loose coupling insert as described in the wiring diagram. Replace loose coupling insert onto the pins at the transducer housing and turn cover cap with PG glanding in the direction desired till it snaps on (4 different starting positions at 90° intervals). Re- tighten the screw at the angle plug. 3.3 Assignment of elbow-type plug: (depending on type) 4-20mA (2-wire connection) voltage (3-wire connection) 1 = supply voltage +Uv 1 = signal + 2 = GND / signal 3 = supply voltage +Uv (4) = supply voltage –Uv The type current or voltage output is set by works and cannot be changed 3.4 Terminal assignment of meas. cell socket contact no. Standard-Cell (K ~ 0.55) 1 Temperature + 2 Temperature GND 3 Supply 1 4 Signal 1 5 Signal 2 6 Supply 2 7 Not busy 3.5 Usage of Unit-Labels As the transmitter is a multiple purpose device, many different display units are possible, eg. 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! Please refer to table in chapter “Configuration of the device” 3.6 Calibration Services Calibration certificates – DKD-certificates – other certificates: If device should be certificated for its accuracy, it is the best solution to return it with the refering sensors to the manufacturer. Only the manufacturer is capable to do efficient recalibration if necessary to get results of highest accuracy!
