TABLE OF CONTENTSPay special attention to information marked with this sign!Manufacturer reserves the right to make changes in design and software of the device without compromising technical parameters1.SAFETY PRECAUTIONS▪Before using the unit, please read this manual carefully.▪To avoid electrical shock or damage to the device, mechanical and electrical installation have to be performed by a qualified personnel.▪Before turning on the power make sure that all cables are properly connected.▪Before making any modifications to the wiring connections, turn off all voltages applied to the device. ▪You have to ensure proper working conditions, according to the specifications of the device (power supply voltage, humidity, temperature, chapter 5).2.INSTALLATION NOTESThis instrument was designed to provide the appropriate level of resistance to most disturbances that may occur in industrial environments. In environments with unknown level of interference it is recommended to use the following measures to prevent possible interference with operation of the instrument:▪Do not power supply the device from the same line as the power component without the appropriate network filters.▪Use only shielded power and signal cables taking into account that the grounding of the shield should bea single point, made as close to the device as possible.▪Avoid placing signal cables very close and parallel to energy and power cables.▪It is recommended to twist signal cables in pairs.▪Avoid proximity of remote controlled devices, electromagnetic meters, high power loads, loads with phase or group power control and other devices that generate large impulse disturbances.▪Ground or zero metal rails that are used to mount rail devices.Before using the device, remove the protective film from the LED display.3.GENERAL PROCESS ANALOGUE CALIBRATOR CHARACTERISTICS▪This device allows you to control or test devices with current or voltage input (proportional valves, servomotors, inverters, motors, etc.)▪ 2 analogue outputs (working simultaneously):-current 4÷20mA or 0÷20mA (active, cannot be powered from 2 wires current loop)-voltage 0÷10V▪Soft start/stop (ramping) or triangle wave generator with manual or automatic (activated after device power on) trigger.▪Programmable setpoint value, output signal change step, display range, soft start/stop options, communication options, access options and other configuration parameters.▪7-segment LED display with brightness adjustment.▪Optional RS485/RS232 serial interface (galvanically isolated, MODBUS-RTU protocol).▪Parameters configuration methods:-Using IP65 foil keyboard located on the device front panel-Using AR955 programmer or RS485/RS232 interface with PC software (Windows 2000/XP/Vista/7)▪Available free software that allows parameters configuration.▪Access to configuration parameters can be password protected.▪High accuracy and high resistance to interference.▪Available accessories:-AR955 programmer-RS485 to USB converterCAUTION:Before starting work with the process analogue calibrator, read this manual carefully and perform electrical and mechanical installation properly and set parameters correctly.4.PACKAGE CONTENTS▪Process analogue calibrator▪User manual▪Warranty card5.TECHNICAL DATA(1)- Output cannot be powered from two wires current loop6.HOUSING DIMMENSIONS AND INSTALLATION DATA7.TERMINAL STRIPS AND ELECTRICAL CONNECTIONS DESCRIPTIONa)Terminals and output signals descriptionOnly AR955 programmer can be connected to PRG socket. Connecting other devices to PRG socket can damage connected device and AR904 process analogue calibrator.8.BUTTONS DESCRIPTIONa) Buttons functions in setpoint value display mode (normal mode)) )and 9: b) Buttons functions in parameters configuration mode (chapter 10)9.OUTPUTS SETPOINT VALUE CHANGEPressing [UP] or [DOWN] button while setpoint value is being displayed will change the value by pre-set step(parameter 6: , chapter 10, table 10). Changes of the output signal are proportional to changes of the displayed value. Pressing [SET] + [DOWN] buttons together will set output value immediately to lower rangevalue (2: or 4: ) while pressing [SET] + [UP] buttons together will set output value immediately to upperrange value (3: or 5: ). In addition, the output signal may be given also in parameters programming mode(parameter 7: ) and using serial interface RS485/RS232 or AR955 programmer (chapter 15, table 15). Moreover, it is possible to set the setpoint value outside of the display range based on the parameters 2: and 3:. The value of this override that can be set using the buttons is ±5% for 4÷20mA (2÷10V) output and 6,2% for the remaining outputs.10.CONFIGURATION PARAMETERS SETUPAll configuration parameters of the device are saved in the non-volatile EEPROM internal memory. Two parameters configuration methods are available:ing IP65 foil keyboard located on the front panel of the device:-From the setpoint value display mode enter configuration menu (press and hold for more than 1 second [UP] and [DOWN] buttons together). If parameter 13: (password protection is turned on), display will show message and then with first digit blinking. Using [UP] or [DOWN] button enter protection password (by default parameter 12: ). To proceed to the next digit or confirm the code use [SET] button.-After opening configuration menu you will see mnemonic parameter names ( <-> <-> <-> etc.), [UP] button will proceed to the next parameter and [DOWN] button will go back to theprevious parameter (all parameters are listed in table 10).-To change or display current parameter value press the [SET] button.-Using [UP] or [DOWN] button change the edited parameter value.-Confirm modified value using [SET] button or cancel using [UP] and [DOWN] buttons (simultaneously), then parameter name will be displayed.ing RS485/RS232 port or AR955 programmer and pc software ARSOFT-WZ1:-Connect process analogue calibrator to the PC port and start ARSOFT-WZ1 application.-After connection is established application window will display current setpoint value.-Device parameters can be displayed and modified in the parameters configuration window.-New paramete rs values have to be saved using “Zatwierdź zmiany” button.-Current configuration can be saved in a file or can be read from the file.CAUTION:-Do not use RS485/RS232 port and AR955 programmer simultaneously, because communication errors will occur.Table 10.

This function works as shown on the below charts (illustrations 11.1, 11.2, 11,3). To turn on this function you will have to configure soft start time (rising slope,parameter 8: , chapter 10) or soft stop time (falling slope, parameter 9: ) and trigger mode (parameter10: ). If both times are different than 0 (8: and 9: ) device outputs will generate triangle periodicalsignal. Amplitudes (end values) of output signals are defined by parameter 2: , 3: , 4: and 5:. Function is activated automatically after device power on (when parameter 10: ) or manually (10: ) using [SET] button (pressed and hold for more than 1.5 seconds). Moreover ramp function can be stopped and resumed at any time using [SET] button (short message will be displayed - start or - stop). Output status in this mode is refreshed 4 times per second.Illustration 11.1. Output status in soft start mode (parameter ).Illustration 11.2.

The DAC904 has a high impedance (200kOhm) current output with a nominal range of 20mA and an output compliance of up to 1.25V. The differential outputs allow for both a differential or single-ended analog signal interface. The close matching of the current outputs ensures superior dynamic performance in the differential configuration, which can be implemented with a transformer.
