- Page 3 Please read the safety precautions carefully before operating the product. With each product you purchase from 4B, there are some basic but important safety considerations you must follow to be sure your purchase is permitted to perform its design function and operate properly and safely, giving you many years of reliable service.
- Page 4 SELECT A QUALIFIED AND COMPETENT INSTALLER Correct installation of the product is important for safety and performance. If you have not asked 4B to perform the installation of the unit on your behalf, it is critical for the safety of your operation and those who may perform work on your operation that you select a qualified and competent electrical installer to undertake the installation.
- Page 5 F500 FIELDBUS ADAPTER. INTRODUCTION This version of the F500 Elite Fieldbus adapter had been designed to work as a Watchdog Elite communications gateway and has been designed specifically to allow up to 7 Watchdog NTC control units to be networked together through their own built in communications system.

- Page 7 INSTALLATION INSTRUCTIONS The Control Unit The Control Unit box should be installed in a suitable control or starter switch room. The box should have sufficient space to open the lid for wiring. The Control Unit is susceptible to static voltage. Connection of a clean ground to terminal 29 is essential for optimum performance.
- Page 8 The above diagram shows the location of the main parts of the Profibus module. The address switches allow the unit slave address to be set between 01 and 99. The left hand switch sets the ten’s digit of the address and the right hand switch sets the unit digit of the address.

- Page 10 Input register data map (Cyclic I/O data transfer – Max 244 bytes see page, see Appendix A for more information). The Watchdog data is automatically read for up to 7 controllers. The data returned is processed and stored in the following format. The position of the data is fixed within the input data table.
- Page 11 The Watchdog speed is encoded in the following manner. Four hexadecimal digits are used to represent the measured speed for the Watchdog. The rightmost three and a half are the main body of the speed and the upper half of the fourth is the position of the decimal place within the information.

Time to alarm Belt slipping. (xx seconds to alarm) In seconds Time to stop Belt slipping: Stop relay about to de-energise.
- Page 13 Several different conditions may occur at the same time whilst the Watchdog is operating. If the Watchdog is running within calibrated range but also detects a motion sensor fault then the information returned may look something like this. ‘2463’ Running at 99% of calibrated speed. Followed three seconds later by 2D--’...
- Page 14 Current calibration value in PPM (Byte 11, 10) These two bytes represent the current calibration speed value in Pulses Per Minute (Default). The representation can be changed to other scaled values by using the display scaling value below. Refer to the Watchdog manual for further details about display scaling.
- Page 15 Relay status (Byte 32) This byte contains information relating to the status of the Watchdog LED’s and Relays. Although the byte is represented in Hexadecimal converting it to binary helps to explain the contents a little better. 0000:0000 The left hand four bits are always 0000 and can be ignored. 0000:0000 The right hand four bits contain the following information.
- Page 16 NOT calibrated (41), see the Watchdog manual for more detail about calibration. Diagnostics Display. The F500 Elite is equipped with a simple RS232 serial interface. This interface can be used to monitor the communications with the Watchdog Elite. The information displayed contains diagnostic data about the Fieldbus module and Watchdog number 1.
- Page 17 Fieldbus type = Profibus DP – This describes the type of Fieldbus module which is installed in the F500 Elite. If the Fieldbus module is faulty some or all of this data will change to suggest which area may be at fault. For example, FBI version number might become 245.55.
- Page 18 Check that there is no exception status reported. If only part of the diagnostics data is displayed on the terminal screen then turn the F500 Elite off then back on again without removing power to the display terminal. If the Watchdogs are not responding or are intermittent, check that the termination resistors are correctly fitted.

Should this file become corrupt or is lost then the following information can be used to recreate the file. The F500 does not require the use of the GSD file in order to operate correctly and this is only provided as a courtesy to the user.
