3. Safety and EMC Information GENERAL This indicator is intended for industrial temperature and process applications when it will meet the requirements of the European Directives on Safety and EMC. Use in other applications, or failure to observe the installation instructions of this handbook may impair safety or EMC. The installer must ensure the safety and EMC of any particular installation. The information contained in this manual is subject to change without notice.
Caution: Charged capacitors Before removing an instrument from its sleeve, disconnect the supply and wait at least two minutes to allow capacitors to discharge. It may be convenient to partially withdraw the instrument from the sleeve, then pause before completing the removal. In any case, avoid touching the exposed electronics of an instrument when withdrawing it from the sleeve. Failure to observe these precautions may cause damage to components of the instrument or some discomfort to the user.
Caution: Live sensors The indicator is designed to operate if the temperature sensor is connected directly to an electrical heating element. However, you must ensure that service personnel do not touch connections to these inputs while they are live. With a live sensor, all cables, connectors and switches for connecting the sensor must be mains rated for use in 240Vac CATII. Wiring It is important to connect the indicator in accordance with the wiring data given in this guide.
in conditions of conductive pollution, fit an air filter to the air intake of the cabinet. Where condensation is likely, for example at low temperatures, include a thermostatically controlled heater in the cabinet. This product has been designed to conform to BSEN61010 installation category II, pollution degree 2. These are defined as follows:Installation Category II (CAT II) For equipment on nominal 230V supply, the maximum rated impulse voltage is 2500V.
with an independent temperature sensor, which will isolate the heating circuit. This indicator can be used in addition to a controller as an over temperature device. It is recommended that the relay used to indicate the alarm condition should be set to high alarm configured with sensor break and inverse ‘Inv’ operation so that it relaxes to the alarm condition when power is removed.
4. Switch On 4.1 1. Press any button. The first character will change to a flashing ‘-‘. 2. Press or to change the flashing character to the required code shown in the quick New Indicator If the indicator is new and has not previously been configured it will start up showing the ‘Quick Configuration’ codes. This is a built in tool which enables you to configure the input type and range, the output functions and the display format. ! W code tables –see next page.

4.4.1 Tare Correction Tare correction can be made in Operator Level 1. It is used, for example, when it is required to weigh the contents of a container but not the container itself. The procedure is to place the empty container on the weigh bridge and ‘zero’ the indicator. Since it is likely that following containers will have different tare weights the tare function is available in operator level 1. 1. With the empty container placed on the weigh cell, repeatedly press displayed.

5.3 Strain Gauge Calibration Different strain gauge transducers may be connected to a 32h8i/SG indicator. It is generally necessary to calibrate the instrument to the transducer in use. This can be done in Operator Level 2 using any one of three methods. These are:- 5.3.1 Load Cell Calibration Connect a load cell as shown below:N L Fuse N SHUNT. This is so called since it refers to switching a calibration resistor across one arm of a four wire measurement bridge in a strain gauge transducer (section 5.
5.3.2 Comparison Calibration Comparison calibration is most appropriate when calibrating the indicator against a second reference device. 5.3.3 Shunt Calibration A bridge type strain gauge is connected as shown. Depending on the type of gauge, RCAL may be included internally or supplied as a separate item. The load cell is connected as shown in the previous example. N L 1. In Level 2, press press V or W ° Fuse 3D 3C Signal | 3.
5.3.4 Manual Calibration 1. Remove all pressure from the transducer to establish a zero reference 2. Press ° to scroll to SHUNT and press 5.3.5 Automatic Calibration 1. Remove all pressure from the transducer to establish a zero reference V 2. In Level 2, press 3. Press W or to select the high calibration point for the type of sensor in use. This will normally be 80.0% 3. Press or 4. 5. 40 W ° to scroll to LO.
5.3.6 Calibration Using a Digital Input A digital input may have been set by selecting Z in the quick codes (section 4.1) to allow the transducer to be calibrated automatically via an external source such as a switch or pushbutton. In this case pressing the button will have the same effect as selecting yes in 3 above. 5.3.6.1 Fail Fail will be displayed in any of the above calibration procedures if the calibration is not possible.
5.4 5.4.2 Recipes It is possible to store operating values in up to five different recipes by taking a snapshot of the current settings and storing these in a recipe number. Examples, of typical operating parameters may be alarm setpoint values. A particular recipe number may then be recalled for a particular process. 5.4.1 To Load a Recipe ° 1. In the list of parameters, press rec.no 2. Select a recipe number from 1 to 5 in which the required settings have been stored.
