Page 6: General Description
General Description This series of meters accepts industrial sensors to allow various physical measurements to be made, such a weight, temperature, pressure, humidity etc. Different models are available for different sensor types. The main function of this series is to give a numeric readout of the variable being monitored. Most models include an excitation power output, to power the sensor directly. -

Page 8: Wiring Advice
Wiring Advice This meter uses detachable screw terminal connectors. Refer to the wiring diagram on the following page for the correct positioning of each wire. The conductors you use must be suitable for the meter’s temperature, current and voltage rating, which is broadly described as follows:- Cable Temperature Rating All cables must be rated for operation up to 90C continuous. -

Page 10: Installation Hints For Best Performance
Installation hints for best performance This section offers several suggestions which will help you get the best performance from your system. RS232 and RS485 use comparitively small signals which can easily be corrupted by the potentially high level of electrical noise which can be created by electrical machinery such as motors, welding systems, discharge lighting, AC power inverters and solenoids. -

Page 19: Logic Input Connections & Front Buttons
Logic input connections and front buttons The previous page explained how to select the functions of the 3 logic inputs. You can connect remote contact closures or open NPN collectors to activate these logic inputs. The logic input provides a 5V DC signal. When you connect this to common, a current of 1mA will flow. -
Page 20: Factory Defaults
Factory Defaults You can return the display to its factory default conditions whenever you wish. If you do so, you will permanently loose all your settings and will need to start from the beginning again. The calibration Audit Counter will NOT be reset, there is no way provided to reset this value, as it is intended as a secure record to indicate whether changes have been made to the display since it was last calibrated.. -
Page 21: Scale Factor Adjustment
Scale Factor adjustment After you have calibrated your meter, you can use the SCALE feature to make fine adjust- Quant ments to calibration, without affecting the calibration itself. You must have mode = Examples 1.Changing weight units of measure from kg to pounds You could also use the SCALE to convert your readout from kg to pounds, without affecting the calibration. -
Page 22: Offset Adjustment
Offset adjustment After you have calibrated your meter, you can use the OFFSET feature to make fine addi- tions or subtractions to the reading, without affecting the calibration itself. Quant You must have mode = For example if your weighing structure is altered after calibration and you want to subtract the effect of 37kg of extra metalwork which was welded to the hopper, you can easily do this by entering a value of -37 in the offset value. -
Page 23: Menu Timeout Adjustment
Menu timeout adjustment The display has a default timeout of 60 seconds, to allow you sufficient time to refer to the manual between key operations. You can make this period shorter, if you wish, once you become more familiar with the setup method. -
Page 24: Reverse / Mirror Display Setting
Reverse Display function (mirror image) If you need to be able to see a reflection of the display in a mirror or other reflective surface, for example in a simple heads-up system, or for drivers reversing into a bay, using mirrors only, you can set the display to show as a mirror image. -
Page 25: Bootup Routine Choices
Bootup routine choices When you switch on your meter, it can be set to power up with 3 possible summary mes- sage combinations. The choices are:- boot 0 Segment test, followed by a full summary of software revision, calibration audit number, model number, installed options. boot 1 Segment test followed by model number (Default) -
Page 26: Multi Memory Mem Option
Multi-Program Memory option MEM The three contact closure inputs on the rear of the meter may be used to call up between 1 to 7 additional meter setup memories (pages), if the MEM option has been installed. This allows you to save up to 8 complete sets of independent calibrations, alarm settings, ana- logue output settings and serial comms settings. -
Page 27: Error Codes And Fault Finding
If the Green LED is on, but no flickering of the red is seen, check that the data source has been set to transmit permanently. If the data source is another London Electronics Display, make sure it has been set to mode C1 and that the enable terminal on the serial output connector is connected to data common. -
