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)
in the case of sensing resistors in 3-wire connections, use identical wires;
f)
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;
g)
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 CONTROLLER
the device is intended for control, monitoring, and recording of temperature and other physical values
(humidity, pressure, level, flow rate, speed, etc.) processed into a standard electric signal (0/4÷20 mA, 0÷10 V,
0÷60 mV, 0÷850 Ω), with the possibility to present 1 to 4 measurement channels;
4 universal inputs (for thermoresistance and thermocouple sensors and for standard analogue signals, not
galvanically isolated) with the possibility to create inter-channel mathematical formulas such as difference,
average, sum, larger or smaller than, and ratio of measured values;
4 control/alarm outputs with independent adjustment algorithms:
ON-OFF with hysteresis, PID, autotuning PID, 12-section programmed control;
an optional module of 4 analogue outputs (0/4÷20 mA and 0/2V÷10V) and 5 functional binary inputs (BIN) to
change the operating modes of the associated outputs (control start/stop, selection of the day/night setpoint
value, manual/automatic mode for outputs); the analogue outputs are logically connected to the two-state
outputs (P/SSR) and are used for control or retransmission of measurements and setpoint values; the inputs
and the outputs are not insulated (common ground);
selection of setpoint values for outputs from among 2 defined for each output, the common value from the 1st
output (without and with offset for 3-way control), from the selected program or measurement from any input;
selection of independent PID sets (from the 8 available sets) for individual setpoint values (gain scheduling);
advanced automatic PID parameter selection function with fuzzy logic elements for each of the outputs;
4 programs with the possibility to define for each section such parameters as type (gradient/time/stop),
setpoint value, hysteresis, set of PID parameters, selection and status of auxiliary output, sound alarm, etc.;
time control/timer, options: continuous operation, periodic daily (hourly), or limited by date and time;
manual mode (open control loop) available for 2-state and analogue outputs with setting of the output signal
value in the range of 0÷100% (the impulse period or the entire range of variability for mA/V);
possibility to select the measured values to be displayed and, independently, the type of control signals for the
outputs (associated inputs or mathematic functions on the measurement signals, such as difference, average, etc.);
possibility to assign many outputs to one measurement channel and many inputs to one output;
available sound and visual signalling of the status of operation of outputs and email alarm notification;
programmable type of control/alarm: heating, cooling, in the band, outside of the band, manual mode;
recording of data in a standard text file located in the internal memory of the controller (4 GB) or an USB
memory in a FAT system, with possibility to edit in spreadsheet software, e.g. Microsoft Excel;
rich standard equipment with serial interfaces: USB (for work with a computer and USB memories), RS485
(MODBUS-RTU), and Ethernet (100base-T, TCP/IP protocols: MODBUS-TCP, HTTP, SMTP, etc.);
a WWW server for work with any web browser (Opera, IE, Firefox, etc.); the site contains information about active
