2. INSTALLATION

2-1. ConnectionThe cable is six wire multicore and covered with a thermoplastic TPE. The wires are also covered with thermoplastic TPE individually and coloured. The cable connections are supplied with 2 mm terminations for connection to the transmitter, or connection box: these pins quarantee a correct and simple connection to the terminals.

Figure 2-0. Sensor Wiring

At the instrument end the cable termination tags are numbered to correspond with their respective terminals of the transmitters.

NOTE:If the cable is used with a connection box, type BA10 then special purpose cable, type WF10 must be used between connection box and transmitter connected to the same terminals as the cell cable. A maximum of 50 metres total cable length is permissable.

2-2. MountingThe mounting is by a compression gland or sanitary adapter, giving a simple effective method of direct insertion in process pipework. For mounting the retractable sensor refer to the instruction manual of the PR4A retractable holder. Before mounting a cell in a process plant environment the following points should be considered:

ssecorp fo wolf ,evitatneserper ,doog a -liquid through the cell should exist. Hence, the cell must be mounted in the process

in such a way that the flow through it represents the true composition of the liquid. The flow through the cell should be uninterrupted and the cell should not be mounted at a “dead” angle.

yaw a hcus ni detnuom eb dluohs llec eht -to allow easy removal for maintenance. It is recommended that the cell is mounted in a ‘by-pass’ directly behind a drain valve.

2-3. Safety warningFor SC4A..AD to avoid the sensor shooting out, never install in application where pressure can exceed specified maximum. Never loosen mounting nut while system is pressurised.

2-4. CommisioningThe sensor cable is marked with a label specifying complete MS mode, Serialnumber and calibrated cell constant*. This cell constant must be entered in the EXA transmitter to achive an accurate measurement.

* Always specify complete MS code and serialnumber in communication with Yokogawa organisation with regards to performance issues or warranty matters.

3. OPERATION AND MAINTENANCE

3-1. Checking the cellIf a fault occurs, first check the cell for visible damage. If damage is not appar-ent, check the cell resistances measuring between the cable connections.a. 11 and 12 (or connector pins 1 and 2)b. 11 and 13 (or connector pins 1 and 3)c. 12 and 13 (or connector pins 2 and 3)d. 12 and 15 (or connector pins 4 and 5)e. 15 and 16 (or connector pins 5 and 6)f. 13 and 14 (or connector pins 3 and 4)g. 13 and 15 (or connector pins 3 and 5)

Celltype a, b, c, d, g e, f

SC4A Pt1000 value > 100MΩ < 2Ω

If the cell has become fouled resistance will be developed across the electrodes. These resistances can be measured by making contact directly with the electrode and the relevant pin of the connector.

3-2. Calibration of the cellThe cell constant is determined under laboratory conditions. It is possible that slight variations in the cell constant may occur dependant on the installation. This possible error can be corrected by recalibrating with a solution of known conductivity value. The procedure is descibed in ASTM D1125 or OIML recommendation 56. Sensors with long cables may exhibit an offset in the temperature readings. This can be adjusted in the transmitter or converter. A calibrated thermometer should be used as reference measurement.

NOTES:The specific conductivity value of the solution of known value must be near the value of the liquid to be measured. Specific conductivity is highly temperature dependent, therefore in the above calibration procedure the temperature of the cell and the liquid should be allowed to equalise and should be accurately measured with a calibrated thermometer.

3-3. Cleaning of the cellIf the cell becomes fouled an insulating layer may be formed on the electrodes and consequently, an apparent increase in cell constant may accur, giving a measuring error. This error is:

2 • x 100 %
