IMPORTANT 4 1 2 Water drainage The drainage of water from the instrument panel is free from pressure Two streams of water run off the acrylic block one from the overflow pipe and one from the actual measurement cell Both of the water streams are pooled together in the collection hopper at the bottom left hand corner of the instrument panel The water for the manual tests is withdrawn at the pivoting drainage pipe The water from the hopper must be able to drain downwards freely The recirculation of water in a pressure system is possible with a submerged pump in a collection tank for instance see installation example 4 2 Electric connection The local DIN VDE must be observed for the general electric installation A specialist must always carry out the electrical work The controller and or measurement amplifier should be installed directly on to the instru ment panel and or for the installation of the control cabinet as near to the instrument panel as possible The connecting lines for the pH and redox single rod measuring cells in particular should not be any longer than approx 10 cm without any special precautions If larger distances have to be bridged an impedance transformer then has to be put on the electrode Under no circumstance may the measuring cables be laid directly parallel to the power and control lines or their pipe ducts junctions have to be at a 90 angle Equipoten tial bonding is necessary if the t

29. thorized modifications and production of spare parts The device may only be modified or converted in consultation with the manufacturer Genuine spare parts and accessories authorized by the manufacturer ensure greater safety The use of other parts can void the liability for the subsequent consequences 1 10 General notes of instruction Measuring cables must not be laid parallel or close to power supply or high voltage current lines Interferences would mutilate the measurement At close distances power supply and measuring lines may only cross at a 90 angle The admissible length of the measuring cables must be adhered to with regard to the sen sor used It is of decisive importance whether high impedance e g pH value or low im pedance e g free chlorine sensor measurements are carried out In the case high imped ance measurements make sure that the plug connections are clean and dry plug and the lines do not become brittle due to sharp buckling The screened cables normally used for such measuring lines must be handled according to the prescribed quality Screening may only be connected to ground at one end of the cable preferably at the controller Interface lines must be twisted and screened see recommended cables IMPORTANT If possible a continuous cable from sensor to measuring input should be used An extension of the cable by plugs or terminal socket increases the risk of dis turbances due to contamination humi
