1. SAFETY PRINCIPLES
 before you start to use the device, become familiar with the present instructions;
 in order to avoid electrocution or damage to the device, its mechanical and electrical installation
must be performed by qualified workers;
 before switching on the power supply, make sure that all cables and wires are properly connected;
 before making any modifications to the wire and cable connections, switch off the voltage supplied
to the device;
 ensure proper operating conditions compliant with the technical specification of the device (chapter 5,
power supply voltage, humidity, temperature).
2. INSTALLATION GUIDELINES
The device is designed so as to ensure an appropriate level of immunity to most interferences that may occur in
industrial and household environments. In environments of unknown level of interferences, it is recommended to
implement the following measures so as to prevent potential interference with the operation of the device:
a) do not supply the device from the same lines as high-power equipment without using appropriate
power line filters;
b) use shielded supply, sensor, and signal cables, whereby the earthing of the shield should be single-point
and located as close to the device as possible;
c) avoid running measurement (signal) cables in the direct vicinity of and parallel to power and supply cables;
d) it is recommended to twist the signal wires in pairs or to use a finished twisted-pair cable;
e) avoid proximity of remotely controlled devices, electromagnetic meters, high power loads, loads with phase
or group power control, and other devices that cause high impulse disturbances;
f) ground or zero metal rails on which rail-mounted devices are installed.
Make sure to remove the protective film from the LCD display before the first use of the device.
3. GENERAL CHARACTERISTICS OF THE TRANSDUCER
 a high class digital relative humidity and temperature sensor with a protective filter (ABS material as
a standard, slot width 1 mm, and steel wire mesh with mesh size of 0.15 mm);
 a probe integrated with the enclosure, external or on a stainless steel pipe;
 a current output, 4- 0 mA ( -wire, with power supply from the current loop); a voltage output 0-10 V

 temperature compensation of humidity measurement, high measurement stability;
 programmable processing ranges for humidity and temperature;
 an LCD display with a keypad (option) that enables configuration of parameters;
 configuration of parameters with the keypad, through the RS485 or PRG port (programmer AR956 or AR955)
and free ARsoft-CFG software that enables quick setting and copying of all configuration parameters;

9. SETTING OF THE CONFIGURATION PARAMETERS
All the configuration parameters of the device are stored in the non-volatile internal memory.
There are two parameter configuration methods:
1.
Using the keypad on the control panel:
−from the mode where the input measurements are displayed in the configuration menu (press the [UP]
and [DOWN] buttons simultaneously for more than 1 second) until the ConF message appears
−after entering the main configuration menu (with the message ConF ) the display shows a mnemonic name
of the parameter (Dot <-> ch-1 <-> ch-2 <->, etc.)
−press the [UP] or [DOWN] button to go to the relevant parameter
−to change the value of the current parameter, press briefly the [SET] button (the parameter blinks in the
edition mode)
−use buttons [UP] or [DOWN] to change the value of the edited parameter;
−approve the changed value of the parameter by pressing the [SET] button or cancel it by pressing the [UP]
and [DOWN] buttons (briefly press them simultaneously) - by pressing the [UP] and [DOWN] buttons
again, you will return to the main configuration menu (one level above)
−to exit the configuration: press the [UP] and [DOWN] buttons for a long moment or wait approx. minutes
2.
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 values and are displayed in the software’s
window;
−setting and viewing of the device parameters is possible in the parameter edition window;
−new parameter values must be approved with the App ove 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 P og am options check the configuration of the port and the MODBUS add ess of the device
(transmission speed ,400 bit/s, address MODBUS=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.
If a difference is found between the indications and the actual measured values, it is possible to tune the zero and
the sensitivity for the specific sensor: parameters coH1 , cot2 (calibration of the zero point) and cGH1 , cGt2
(calibration of the inclination).
In order to restore the default settings, use the file with the default configuration in the ARSOFT-CFG software.
NOTE:
The transmission parameters for the AR956 programmer in the ARSOFT-CFG software are the following: ,400 bit/s,
address MODBUS = 1

11. CONNECTING THE CONTROLLER TO A COMPUTER AND AVAILABLE SOFTWARE
It may be useful (or necessary) to connect the transducer to a computer in order to configure parameters, which
also enables copying the setting to other transducers of the same type.
As a standard, the transducers are equipped with a PR port which enables connection to a computer using an
AR956 programmer using the MODBUS-RTU communication protocol and the following transmission parameters:
speed = ,400 bit/s, MODBUS address = 1.
The following application is available (on a CD supplied with the AR956 programmer or to be downloaded from
the Internet at www.apa .pl, “Download” section, for operating systems Windows Vista/7/8/10):
Name
Softwa e desc iption
ARsoft-CFG
(free)
-
display of current measurement data from the connected device
- setting configuration parameters, such as the measurement signal, the indication
range, the options, the display, etc.
- creation on the disk of a "cfg" file with the current configuration of the parameters for
future use (copying of configuration)
- the software requires communication with the device via the PR port (AR956 or AR955)
A detailed description of the aforementioned application can be found in the installation folder.
NOTE:
Before a connection is established, make sure that the MODBUS address and the transmission speed in the options
of the ARsoft software are the same as the settings of the device (this applies to the version with the RS485).
Moreover, in the options of the ARsoft software, set the number of the COM serial port in use (in the case of the
AR956/AR955 programmer or the RS485/USB converter, it is the number assigned by the operating system during
installation of the drivers).
12. RS485 COMMUNICATION INTERFACE (acc. to EIA RS-485)
The installation specification for the RS485- standard interface is the following:
- maximum cable length - 1 km (observe the installation guidelines, chapter , sub-items b, c, and d)
- maximum number of devices in a RS485 line - 30, in order to increase the number, use RS485/RS/485 amplifiers
- termination and polarizing resistors when the MASTER is at the start of the line (Fig. 1 ):
- at the start of the line - x 8 0 Ω to the ground and +5 V of the MASTER and 150 Ω between lines
- at the end of the line - 150 Ω between lines
- termination and polarizing resistors when the MASTER is in the center of the line:
- at the converter - x 8 0 Ω, to the ground and +5 V of the converter
- at both ends of the line - 150 Ω each between lines
Equipment from different manufacturers that form the RS485 network (e.g. RS485 converters/USB) may have
integrated polarizing and terminating resistors; in such a case there is no need to use external elements.
