1.
SAFETY RULES
Before using the device, please read this manual carefully, and:
a)
in order to avoid electric shock or damage to the device mechanical and electrical assembly
should be commissioned to qualified personnel
b)
before turning on the power, make sure that all cables have been connected correctly
c)
before modifying cable connections, disconnect the voltage connected to the device
d)
ensure proper working conditions, compliant with the technical data of the device (
chapter 4
, supply voltage,
humidity, temperature, etc.), do not expose the device to direct and strong influence of heat radiation
2. ASSEMBLY RECOMMENDATIONS
The device has been designed to provide an adequate level of resistance to most of the disturbances that can
occur in industrial and home environments. In environments with an unknown level of interference, it is
recommended to use the following measures to prevent any possible disruption of the device's operation:
a)
do not supply power to the device from the same lines as large capacity devices without proper mains filters
b)
use shielding of power, sensor and signal wires, and screen-grounding
should be single-point, made as close as possible to the device
c)
avoid laying measuring (signal) wires in the immediate vicinity and parallel to
power and supply cables
d)
it is recommended to twist signal wires in pairs or use a ready UTP wire
e)
Use the same cables for resistance sensors in a 3-wire connection
f)
avoid the proximity of remotely controlled devices, electromagnetic meters, high power loads,
loads with phase or group power control and other devices generating large impulse noise
g)
ground or neutralize the metal rails on which the rail devices are mounted
Before starting working with the device, remove the protective foil of the LED display.
3. GENERAL CHARACTERISTIC OF CONTROLLERS. ACCESSORIES AND KIT CONTENTS
control and supervision of temperature and other physical values (humidity, pressure, flow, level, velocity,
etc.) converted into a standard electrical signal
configurable architecture enabling using in many fields and applications (industrial, heating, food, energy,
etc.)
1 universal measurement input
(RTD, thermocouple TC, analog 0/4÷20mA, 0÷10V, 0÷60mV, 0÷2.5kΩ)
2
(1 for AR602.B)
function keys
(
F
and
SET
) and
digital input
(
BIN
) for quick change of the controller
operating mode, separately programmable: control start/stop, manual/automatic mode for outputs, step
change of the SP setpoint (day/night, i.e.
SEt1
/
SEt3
, with separate control parameters), keypad lock, reset of
errors and alarms STB (LATCH), etc.
3
(2 + 1 LED alarm for AR602.B)
control/alarm outputs
of the on/off type (bi-state P/SSR) with independent
functionalities and control algorithms:
-
ON-OFF with hysteresis
(threshold characteristics for heating and cooling, band alarms within and out of
range and with an offset for three-state control)
-
PID
(
3 separate sets of parameters
to choose from), advanced functions of automatic selection of PID
smart logic
parameters
- programmable operation characteristics (
process controller with timer
, up to
6 segments
, including 3
segments of
ramping
type-slope for heating/cooling or cooling/defrosting, 3 SP setpoints with ON-OFF or
PID control, selection of the auxiliary output and its condition, displaying the remaining time for the entire
segment or after exceeding the SP, etc.)
- thermostat/controller/safety switch
STB
(alarm condition open or closed, erased F/SET/BIN, can also be used
as an
alarm memory
of
LATCH
type , e.g. after exceeding the minimum, maximum or band)
- the ability to control a three-way mixing valve with an actuator (step
control
,
servo
) with two pin inputs
(open - close), implemented on outputs 1 and 2
-
manual mode
(open control loop) with the initial value of the control signal (MV) taken from the current
automatic mode or programmed by the user in the range of 0÷100%, also for sensor failure
