General Description 3000 series™ Controllers are 6-decade seven segment high brightness red LED display instruments based on the industry standard Intel 80C51 series Microprocessor. They are built into half DIN (96mm x 96 mm) panel mounting housings and are supplied to operate on either 115V AC or 230V AC (see Transformer connections on page 4), or 24V DC power supplies, as requested when ordering.
Safety Information for EU Users WARNING This instrument must be earthed when powered from a mains supply (see also Mains Earth on page 8). 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...
Switches and Connections BATCH SET/PROG This is the top central switch on the front panel. During initial setting up of the instrument this switch is used in conjunction with the RESET/PROG switch to gain access to the programming mode (see page 9).
Rear Panel Switching In addition to the front panel controls, the START, RESET and STOP functions are available through terminals on the rear panel. To activate the controls, they must be grounded to 0V. These can be used to automate the batching Rear Panel Terminals +12V DC unregulated @ 80mA (transducer supply) Common...
Mains Earth 3000 ™ Controllers that are supplied to operate on mains power (115V or 230V AC) are fitted SERIES with 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.
Programming the Instrument Calculating a Scaling Factor It is straightforward to calculate a scaling factor for a 3000 Series™ Controller. If a one-for-one count is required then simply enter a scaling factor of 1. If, for example, you have a requirement for counting flow in litres from an associated pulse rate, the following procedure could be followed.
Batch Number To set the Batch number, use the right-hand button (arrow up) to step through the digits sequentially. The left-hand button (arrow left) moves the display one decade. Each decade's value may be set using the right-hand button. When in operation, the instrument will count, and when it reaches the number set as Batch, it will operate the associated relay.
2. Altering values once an instrument has been programmed To change from operating mode, first press and hold down the RESET switch and then press and hold down the BATCH SET switch. The instrument will step through SET 3 …. SET 2 ….
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.
