Page 4: General Description
General description 200T ™ Tachometers are 4-decade seven segment high brightness red LED display MKII SERIES instruments based on the industry standard Intel 80C51 series microprocessor. They are built into half DIN (96 mm x 48 mm) panel mounting housings and can be supplied to operate on 115V or 230V AC or 24V DC power supplies (see Transformer Connections on page 4 and... -
Page 5: Safety Information For Eu Users
Safety Information for EU Users WARNING This instrument must be earthed when powered from a mains supply (see also Mains Earth on page 6). Refer to the rating label for the pre-set voltage and ensure that the instrument voltage corresponds to the intended supply voltage. Important: The wires in the power lead fitted to mains instruments are coloured in accordance with the following code: Green... -
Page 6: Switches And Connections
Switches and connections Switch A This switch is located on the left hand side of the display. When the instrument is in RUN mode and this switch is held down in conjunction with Switch B the instrument is put into set mode (see Setting a Scaling Factor on page 7). -
Page 7: Mains Earth
Mains Earth ™ Tachometers supplied to operate on mains power (115V or 230V AC) are fitted with MKII SERIES a three core mains cable. The Earth is normally connected by an internal link to 0V. For applications where it is found that the mains earth is of poor quality, or when it is essential that the signal input is floating, it may be necessary to remove this link. -
Page 8: Programming The Instrument
Programming the instrument Choice of MODE setting For applications where a low number of pulses per second will be displayed as a speed (RPM etc) leave M1 disconnected and use D = R x S For applications where there are a large number of pulses per displayed unit, such as flow metering applications, connect a link between M1 and ground and use D = R / S . -
Page 9: On An Instrument That Has Been Previously Scaled
If it is necessary to enter a decimal point in the scaling factor you must use Switch A to step to the most significant decade (even if the value for the higher decades is to remain at zero) and then press Switch A once again to move on to the decimal point setting function. -
Page 10: Adjustment Of Sensitivity
By moving the decimal point in the scaling factor by one place to the right an extra decade of discrimination can be achieved: Thus if we make S = 10 then D will read It is now necessary to position the decimal point in the final display. You progress to this stage of the scaling procedure by pressing Switch A once again. -

Page 14: Additional Information
Additional Information Electro-Magnetic Precautions Logitech have designed in a great deal of noise immunity into the product in accordance with EN5001-2 and EN5002-2 (radiated emissions, conducted emissions, ESD, radiated susceptibility and fast burst transient testing) However it is still vital to use good EMC (Electro-Magnetic Compatibility) techniques on installation of both this and other associated electronic equipment and sensors in order to ensure reliable operation. -
