Introduction
Thanks for choosing is controller.
The ISO-RS4 series integrates in a single device the main elements of the control
loop: reading of temperature sensor, control output by SSR module, reading
and control of the current on the load by means of integrated current CT. Serial
communication RS485 and ModbusRTU or CANopen protocol allow the connection
to PC/HMI Panels for supervisory functions/remote control.
This device is provided with alarms functions, management of double action
installation and possibility to be used as expansion controlled by PLC.

This controller has been designed and manufactured in conformity to Low Voltage
Directive 2006/95/EC , 2014/35/EU (LVD) and EMC Directive 2004/108/EC, 2014/30/
EU (EMC). For installation in industrial environments please observe following safety
guidelines:
• Separate control line from power wires.
• Avoid proximity of remote control switches, electromagnetic contactors,
powerful engines and use specic lters.
• Avoid proximity of power groups, especially those with phase control.
• It is strongly recommended to install adequate mains lter on power supply of
the machine where the controller is installed, particularly if supplied 230Vac. The
controller is designed and conceived to be incorporated into other machines,
therefore CE marking on the controller does not exempt the manufacturer of
machines from safety and conformity requirements applying to the machine
itself.

6.1 Meaning of status lights (LED)
RUN Indicates presence of serial communication
OUT1
Normally it indicates the status of output OUT1.
• During test (pressing key), if the command output is OUT1, blinks
with frequency 50ms.
• At the end of current acquisition by the CT, blinks with frequency
0.5s if the operation has been done successfully.
• In case of error, it blinks in alternation with the led OUT 2 (ex.
broken sensor).
OUT2
Normally indicates the status of output OUT2.
• During test (pressing key), if the command output is OUT2, blinks
with frequency 50ms.
• At the end of current acquisition by the CT, blinks with frequency
0.5s if the operation has been done successfully
• In case of error, it blinks in alternation with the led OUT 1 (ex.
broken sensor).

6.2 Key
• If pressed it enables the command output: press for more
than 3 seconds to manage the threshold current reading for
the Heater Break Alarm control.
• If pressed during the modbus address assignment function, it
stores the value assigned by the master (only if the dip1 is all
in OFF).

• Determines modbus slave address, in binary code as indicated

00000001=1; 00000010=2; 00000011=3; 00000100=4; 00000101=5;
00000110 =6; 00000111=7; 01111101=125; 01111110=126;

DIP 2 - Baud rate and loading default values
• If contacts 1..3 are OFF, modbus baud rate is selected on parameter
112 bd . rt.
• If contact 4 is ON, parameters and all eeprom datas are loaded with
default values (default = 19.200baud , address 247, 8n1).
• Determines modbus baud rate, using following values:
001=4800; 010=9600; 011=19200; 100=28800; 101=38400;
110 =57600; 111=115200. (contact 1 = LSB). ex. baud 4800 = 1(ON) 2, 3(OFF)

7 Controller functions
7.1 Loading default values
This procedure allows to restore default settings as pre-selected at the factory.
There are two reset modes:
• Close contact 4 of the dip switch 2 and reopen it at restart.
• Write 9999 on word modbus 500.
After the restore, device restarts.
7.2 Controller Start / Stop and setpoint modication
User can decide if at power-on ISO-plus starts regulation or not, setting parameter
17 init.S. (word 2017). Can modify the controller state writing 1 (start) or 0 (stop) on
word 1204. It is possibile also to modify command setpoint writing on word 1201,
and alarm setpoints on words 1202 and 1203.

12 - User manual
7.3 Automatic tuning
Select 1 on parameter 31 (Tu n e word 2031).
Automatic tuning is always active and analyses constantly the dierence setpoint-
process. If this dierence is greater than the value selected on parameter 47 m.G. tu .
(Max Gap Tune - word 2047), the ISO-plus decides autonomously when to modify
PID parameters.
7.4 Manual tuning
Select 2 on parameter 31 (Tu n e word 2031).
The manual procedure allows the user a greater exibility on deciding when to
update PID algorithm parameters.
This procedure is activated writing 1 on the word modbus 1205. The reference
threshold to calculate the new PID parameters is given by the result of the following
operation:
Tune threshold = Setpoint (word 1201) – Par. 32 s.d.tu. (word 2032)
Ex.: if setpoint is 100.0°C and Par. 32 s.d.tu. is 20.0°C, the threshold to calculate PID
parameters is (100.0–20.0) = 80.0°C.
N.B.: for greater accuracy in the calculation of PID parameters it is recommended to
launch the manual tuning when the process is far from setpoint.
7.5 AutoTuning Launch “Once”
Set 3 on parameter 31 tune (word 2031). Autotuning procedure is executed only
once at next ISO-plus restart. If the procedure doesn’t work, will be executed at next
restart.
7.6 Synchronized tuning
Select 4 on parameter 31 (Tu n e word 2031).
This procedure has been conceived to calculate correct PID values on multi-zone
systems, where each temperature is inuenced by the adjacent zones.
Writing on word 1205, the device works as follows:
Word 1004 value Action
0Tune o.
1Command output OFF
2Command output ON
3Tune active
4Tune completed: command output OFF (read only)
5Tune not available: softstart function enabled (only reading)
The operation of this Tuning mode is the following: the master switches-o or
turns-on all zones (value 1 or 2 on word 1205) for a time long enough to create
inertia on the system.
At this point the autotuning is launched (value 3 on word 1205). The controller
calculates the new PID values. When the procedure ends, it switches-o the control
output and sets the value 4 on word 1205. The master, which should always read the
