1. SAFETY RULES
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 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:
do not supply the device from the same lines as high-power equipment without using appropriate power line
filters;
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;
avoid running measurement (signal) cables in the direct vicinity of and parallel to power and supply cables;
it is recommended to use twisted pair signal cables;
in the case of sensing resistors in 3-wire connections, use identical wires;
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;
ground or zero metal rails on which rail-mounted devices are installed.
Make sure to remove the protective film from the LED display before the first use of the device.
3. GENERAL CHARACTERISTICS OF THE CONTROLLERS
control and monitoring of temperature and other physical values (humidity, pressure, level, speed, etc.)
processed to a standard electrical signal (0/4÷20mA, 0÷10V, 0÷60mV, 0÷2,5kΩ);
2 universal measurement inputs (thermoresistant, thermocouple, and analog) with mathematical functions
(subtraction, addition, and average of measurements from two inputs);
programmable functional button to change the operating mode of the controller: start/stop of control,
manual mode for outputs, step change of the set value (day/night), keyboard lock, view of measured values;
3 independent ON/Off type outputs (2- and 3-way adjustment) with the following control characteristics:
- output 1 (main): ON-OFF with hysteresis, PID, AUTOTUNING PID
- output 2, 3 (auxiliary/alarm): ON-OFF with hysteresis
analog output 0/4÷20mA or 0/2÷10V (continuous-control, retransmission)
possibility to convert the input signals into the analog output standard in the retransmission mode;
selection of the value controlling the operation of each output (any input, subtraction, addition, average
of measurements);
advanced PID parameter selection function with fuzzy logic elements;
manual mode (open control loop) available for binary outputs and the analog output, which makes it possible
to set the value of the output signal in the range of 0-100%; possibility of self-activation in the event
of sensor failure;
programmable operating characteristics (process controller, ramping);
an integrated 24 V DC power supply supplying the field transducers;
a two-line digital LED display with control of illumination brightness: a
