  • Page 28: Compatibility Hint

    1. Compatibility Hint This product is a successor model of the thousandfold approved converter type FU251. The new product is suitable for a 100% replacement of the previous model, however some differences must be observed with DIL switch and parameter settings. Some essential advantages of FU252 compared to FU251 are: •...

  • Page 29: Introduction

    2. Introduction FU 252 is a small and low-cost, but highly performing converter for industrial applications, where one frequency or two different frequencies need to be converted into an analogue signal or a serial data format. The unit has been designed as a compact module with 12 screw terminals and a 9-position SUB-D connector (female).

  • Page 30: Operating Range

    Operating range 2.2. The full scale frequency (i.e. the input frequency where the analogue output reaches 10 V or 20 mA) can be set in a range from –1 MHz to +1 MHz. The operating range of the unit can be assigned to any frequency window inside this frequency range.

  • Page 31: Terminal Assignments And Connections

    3. Terminal Assignments and Connections We recommend connecting the Minus wire of the power supply to earth potential. Please observe that, under poor earthing and grounding conditions, multiple earth connections of screens and GND terminals may cause severe problems. In such cases it may be better to have only one central earthing point for the whole system.

  • Page 32: Example For Use Of Htl Encoders

    Example for use of HTL encoders 3.2. The encoder may be supplied from the same source as the converter, or from another source. +24V HTL encoder FU 252 Screen 12 (GND) Proximity switches, photocells etc. 3.3. These connections are fully similar to a HTL incremental encoder. With single channel operation, input B remains unconnected or can be used to select the output polarity.

  • Page 33: Serial Interface

    Serial interface 3.5. The unit provides a RS232 interface and a RS485 interface, however only one of the two can be used at a time. Serial communication allows to read out conversion results and to set parameters and variables by PC, according to need. GND int.

  • Page 34: Dil Switch Settings

    4. DIL Switch Settings There is one 8-position switch located on the top side (DIL1), and another 8-position switch is located on the bottom side of the unit (DIL2). These switches provide major settings of the desired properties of the unit. Changes of switch settings will become active only after cycling the power supply of the unit! Teach button...

  • Page 38: Commissioning

    5. Commissioning With all basic applications, you can use the Teach feature for commissioning of the unit. Extended functions need a PC for setup and are described under section 7. As a first step it is advisable to check the input frequencies by means of the LED marked “Status”.

  • Page 39: Conversion Of One Only Frequency (Single Channel Or Dual Channel With Direction Signal)

    Conversion of one only frequency 5.1. (single channel or dual channel with direction signal) Make sure that the DIL switches are set according to the encoder you use, and that position 6 of switch DIL1 is OFF (Teach function active). Self test: Upon power up, both front LED’s must be lit first, and the yellow status LED must switch off after the self test has been concluded successfully (approx.1 sec.).
