Installation and dimensions The ambient temperature and humidity of the installation environment must be within the limits of the instrument specifications. (See chapter 2). 3-1-1. Installation site The EXA transmitter is weatherproof and can be installed inside or outside. It should, however, be installed as close as possible to the sensor to avoid long cable runs between sensor and transmitter.

3-3 Installation and Wiring 3-2. Wiring of power supply mA 3-2-1. General precautions Do not activate the power supply yet. First make sure that the DC-power supply is according to the specifications given. WARNING DO NOT USE ALTERNATING CURRENT OR MAINS POWER SUPPLY! ! The cable leading to the distributor (power supply) or safety barrier transports power to and output signal from the transmitter. Use a two conductor shielded cable with a size of at least 1.25 mm2 and an outside diameter of 6 to 12 mm.
Installation and Wiring 3-4 3-3-2. Wiring other galvanic sensors Consult the users manual for the color identification of the sensor cable. - The temperature sensor has two wires and must be connected to the terminal 11 and 12. - The measuring electrode: the cathode must be connected to terminal 13. - The reference electrode: the anode must be connected to terminal 15. - The overall shield of the cable must be connected to terminal 14 if there is one available. - Place the jumper in the GALVANIC position.
3-5 Installation and Wiring Extension cable may be purchased in bulk quantities, cut to length. Then it is necessary to terminate the cable as shown below. Termination procedure for WF10 cable. 1. Slide 3 cm of heat shrink tube (9 x 1.5) over the cable end to be terminated. 2. Strip 9 cm of the outer (black) insulating material, taking care not to cut or damage internal cores. 3 cm heat shrink 9 cm remove insulation Figure 3-9a. 3.

Calibration Procedure 6-1 6. CALIBRATION PROCEDURE Calibration of the dissolved oxygen analyzer is performed in the following situations: • When a new dissolved oxygen sensor is installed. • When the membrane is replaced and/or the electrolyte solution is replaced • When the sensor has been disassembled and reassembled for maintenance • When the measuring error after cleaning exceeds the acceptable deviation from reference method • When error message E16 indicates the need for maintenance 6-1.
6-2 Calibration Procedure 6-2. Calibration procedure using air calibration method 6-2-1. Preparation Move the sensor to a maintenance site and wash off any dirt on the membrane. Lightly wipe off any remaining water from the membrane with a soft tissue. Expose the sensor to the air in an environment where there is no temperature change and no wind (a convenient way to accomplish this environment is to place the sensor in an empty bucket).
Calibration Procedure 6-3 If both zero and span calibration are used, it is better to start with span calibration in spite of normal calibration sequence with analog instrumentation. Otherwise the sensor must be rinsed off carefully to prevent ingress of oxygen absorbing sulfite in the aerated water. Note: Zero calibration in the sodium sulfite solution takes a long time. Even after CAL.END prompt it is necessary to wait 40-50 minutes before zero adjustment can be made.

Maintenance 7-1 7.

It also serves to prevent problems from arising. This chapter describes daily inspection and maintenance for the purpose of maintaining system performance. 7-1.

8-1 Troubleshooting 8. TROUBLESHOOTING This chapter describes the countermeasures for failures, classifying the cases into three categories: dissolved-oxygen transmitter failure, detection of failure with the self-diagnosis function, and abnormal measured values. The causes for abnormal measured values are not limited to equipment failures.
Troubleshooting 8-2 Error Generation No. Mode E10 All modes mA mA Error content and Causes Measures EEPROM writing failure Electronic circuit failure Turn off the power and then turn it back on and check whether or not the system returns to normal.
