4 ELECTRICAL CONNECTIONS Warning. Before making any connections, ensure that the power supply, any high voltage-operated control circuits and high common mode voltages are switched off. 4.1 Access to Terminals 4.1.1 Wall-/Pipe-mounted Instruments – Fig. 4.1 Remove protection cover slide down Slacken captive...
4 ELECTRICAL CONNECTIONS… 4.2 Connections, General Information. • Earthing (grounding) – stud terminal(s) is fitted to the transmitter case for bus-bar earth (ground) connection – see Fig. 4.1 or 4.5. • Cable routing – always route signal output/pH electrode cable leads and mains-carrying/relay cables separately, ideally in earthed metal conduit.

5 CONTROLS AND DISPLAYS 5.1 Displays – Fig. 5.1 The display comprises a 5-digit, 7-segment digital upper Advance to next page display line and a 16-character dot-matrix lower display line. The upper display line shows actual values of pH, Page 1 Page 2 temperature, alarm set points or programmable parameters.
6 OPERATION 6.1 Instrument Start-up Ensure all electrical connections have been made correctly and switch on the power supply. If the instrument is being commissioned for the first time its parameters must be programmed, as detailed in Section 7, before carrying out a pH Calibration. 6.2 Operation –...

Monitoring pH If the Water Wash cycle is selected (Models 4631 or 4636 only), an alternative message, WASH IN PROCESS WASH IN PROCESS, is displayed. The Alarm 1 status and the retransmission value are held in their pre-cycle condition for the duration of the wash cycle.

Slope Value: l 0 0 0 . a value between the programmed minimum % slope value (see pH Calibration Minimum in the on page 25) and 105% should be displayed. Slope Value Set Up Parameters Page % Slope Value If the value is outside these limits the electrode system must be checked.
…6 OPERATION 6.2.2 Single Point pH Calibration A single point calibration may be carried out in preference to a two point calibration provided a two point calibration has been carried out since installing the instrument. This procedure assumes an electrode pair with perfect Nernstian response, i.e. 59.16mV per pH change at 25°C.
6.2.3 Two-point pH Calibration (Automatic Mode) An automatic pH calibration involves standardizing the instrument and electrode system using ABB supplied buffer solutions or non-ABB buffer solutions of 4, 7, 9 and 10pH. Before starting pH calibration, check the Temp Comp setting in the Set Up –...

6 OPERATION… 6.2.4 Two-point pH Calibration (Manual Mode) A manual pH calibration involves standardizing the instrument and the electrode system using any two suitable buffer solutions which give a reasonable span and encompass the anticipated measuring range. Before starting pH calibration, check the Temp Comp setting in the –...
