1. SAFETY RULES
n read this instruction manual thoroughly before commencing to use this device
nbefore switching on the power supply, make sure that all cables are appropriately connected to avoid
device damage
nensure suitable operating conditions in line with the device specification (supply voltage, humidity,
temperature)
nswitch off power supply before attempting any modification of connected cables
2. INSTALLATION RECOMMENDATIONS
The device has been designed to ensure a suitable level of immunity to the majority of disturbances that
can occur in an industrial environment. In environments where the level of interference is unknown it is
recommended to use the following measures preventing the potential interference of instrument operation:
n do not supply the voltage from the same lines as high power devices without using appropriate line filters
n use screened supply, sensor and signal cables, the screens should be earthed on one end only as close
to the instrument as possible
n uavoid laying supply and signal cables directly next to and in parallel to electrical power cables
and supply cables
n it is recommended to twist signal cables in pairs
n in the case of resistance sensors with 3-cable connections identical cables should be used
n avoid installing the instrument in proximity to remotely controlled devices, electromagnetic measuring
instruments, high power loads, loads with phase or group power control and other devices generating
impulse interference
n earth or neutrally ground metal bars on which bar instruments are mounted

8. PROGRAMMING CONFIGURATION PARAMETERS
All the configuration parameters of the device are stored in the non-volatile internal memory.
When the device is switched on for the first time, an error may occur due to the lack of a sensor or the fact
that the sensor that is connected is not one that is factory-programmed. In such a situation, the appropriate
sensor or analog signal should be connected or the parameter configuration must be performed.
Methods of parameter configuration via the PR socket (accessible by opening the transparent front cover):
1. Use the AR956 programmer and the ARSOFT-CFG software to:
-connect the device to a computer port and to start and configure the ARSOFT-CFG application
-after the connection has been established, the current measured value is displayed in the window
of the software
-setting and viewing of the device parameters is possible in the parameter configuration window
-new parameter values must be approved with the Approve changes button
-the current configuration can be saved in a file or set using values read from a file
NOTE:
-before disconnecting the device from a computer, press the Disconnect device button (ARSOFT-CFG)
-in the event of no response:
-in the Program options check the configuration of the port and the MODBUS address of the device
(transmission speed 2,400 bit/s, MODBUS address=1)
-make sure that the serial port drivers in the computer have been properly installed for the AR956
programmer
-disconnect for a few seconds and then reconnect the AR956 programmer
-restart the computer
- if the AR955 programmer is used instead of the AR956 programmer, connect the power supply voltage
to the transducer (put it in the current loop)
2. Use the autonomous AR950 programmer to:
-connect the power supply voltage to the transducer;
-use the cable included in the set to connect the AR950 programmer to the device being configured
(an AR5xx series transducer);
-the programmer can be connected both before the power supply is switched on and during operation
of the device;
-enter the configuration parameters programming mode by pressing (for about 2 s) the CONF button until
the ConF message briefly appears on the display and then the mnemonic name of the first parameter
is displayed ( inP ); by pressing the button, you can move to the next parameter, and by pressing
the button - to the previous parameter ( :inP FiLt :dot …); a list of configuration parameters
can be found in the user instruction of the device being configured;
-in order to change or view the value of the current parameter, press SET (edition of the parameter);
-by using or , you can change the value of the current parameter;
-by pressing SET again, you can save the edited value and return to the parameter name display
(e.g. FiLt );
-in the parameter edition mode, by pressing ESC for a short time, you can cancel the changes and return
to the parameter name display mode;
-you can exit the configuration parameters programming mode by pressing the ESC button for a long time
(approx. 1 s); otherwise, the mode is switched off after approx. 2 minutes;
-in the normal mode, the measured value is displayed;
Detailed information can be found in the user instruction of the AR950 programmer.
In the event of indications different than the actual value of the input signal, the zero and the sensitivity of
a sensor can be tuned: parameters 7: cALo (zero offset) and 8: cALG (sensitivity).
In order to restore the default settings, use the file with the default configuration in ARSOFT-CFG software.

11. NOTES
10. INDICATION OF MEASURING ERRORS
The transducer detects the following measuring errors:
- low or high processing range exceeded
- connected sensor differs from the one set in configuration parameters
- sensor circuit damaged
Indication of measuring errors:
- LED flashes
- 7 -
9. OUTPUT CONFIGURATION
Input signal is directly proportional to the measured signal within the range set with parameters 5: rbot
and 6: rtoP. Figures below present the principle of operation of the analogue output.
Remarks: (1) - dla FiLt=2 response time is about 0,35s, for FiLt=15 about 1,6s. A higher filtering level
corresponds to a smoother measurement value and longer response time
(2) - this applies to displaying data on the AR950 programmer
Reverse characteristics can be obtained by setting rbot > rtop
for AR553: rbot = -30.0, rtop = 60.0
