1. SAFETY RULES
read this manual carefully before starting to use the device;
to prevent the hazard of electric shock or equipment damage the mechanical and electrical installation should
be performed by qualified personnel;
before powering the device make sure all leads have been connected correctly;
disconnect the power supply
before making any modifications of the leads configurations;
ensure correct operating conditions (supply voltage, temperature, humidity, see section 5).
INSTALLATION RECOMMENDATION
he controller has been designed to provide an adequate level of immunity to most disturbances which can
appear in industrial environments. In environments with unknown disturbance level it is recommended to use the
following preventive measures:
without proper line filters do not provide the power supply to the controller from the same lines which supply
large equipment;
use screened power supply, sensor and signal cables; the screen earthing shall be one-point type, located as
close to the device as possible;
avoid placing the measuring (signal) leads
in direct vicinity of and parallel to power supply cables or lines;
it is recommended to twist the signal leads in pairs;
use identical leads
for resistance sensors in 3-lead
connection;
avoid proximity of remotely controlled devices, electromagnetic meters, large electrical loads, loads with phase
or group power control, and other devices generating large pulse disturbance;
provide earthing or neutralization to metal rails on which the rail-mounted devices are installed.
Before using the device, remove the screen protective film from LED display.
3. GENERAL FEATURES OF CONTROLLERS
control and supervision of temperature and other physical magnitudes (humidity, pressure, level, velocity, etc.)
converted to standard electrical signal (0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5kΩ);
1 multi-purpose measuring input (resistance thermometers, thermocouple, and analogue);
Programmable digital input and function button to change the controller operation mode:
start/stop regulation, manual mode for output, step change set value (daily/night), lock keypad;
2 or 3 ON-OFF outputs with the following control characteristics:
- output 1 (main): ON-OFF with hysteresis, PID, PID AU O UNING
- output 2, 3 (auxiliary/alarm): ON-OFF with hysteresis
0/4÷20mA or 0/2÷10V analogue outputs (control-continuous, retransmission);
possible conversion of input signals to the analogue output standard in the signal retransmission mode;
advanced function of PID parameters selection with fuzzy logic elements;
manual mode (open control loop) available to switching and analogue outputs allowing to set the input signal
value in the 0 ÷ 100% range, the ability to auto-activation for (
input)
sensor failure;
programmable programmable operating characteristics (process controller, ramping)
built-in 24Vdc power supply to supply field transmitters;
two-line LED display with brightness adjustment OP display – measured value, BO OM– input 1_set value;
RS485 serial interface (galvanically isolated, MODBUS-R U protocol);
programmable input type, range of indications (for analogue inputs), options of control, alarms, communication,
access, and other configuration parameters;
line resistance compensation for resistance and thermocouple cold junction compensation;
password-protected access to configuration parameters;
