7. SOFT START FUNCTION
At start up or when the input signal value is lower than the “Set point 1 – drb”, the controller uses
a dynamic set point to control the system. The step o the dynamic set point is given by the “dSi”
parameter value and each step o temperature is controlled during the “dSt” interval time.
For example at the start up, the controller added to the probe value Ta (usually the ambient
temperature) the “dSi” value then or the successive time, set with “dSt” parameter, the controller
will work to reach this irst dynamic set point. This procedure will be repeated until the probe
signal value reaches the “Set point – drb” value, at this point the So t Start is disabled and the PID
unction will control the system. When the controlled signal goes out o the band then the So t
Start unction restarts.
By setting “drb=0” the So t Start unction is manually disabled, in this case the relay output is
always on until the temperature will enter within the Proportional Band value.

8. PROPORTIONAL FUNCTION
The PID unction modulates the activation o the irst output using an appropriate ON/OFF cycle:
the duration o the cycle is imposed by the parameter “Cyt”. I the actory set values o the
parameters relating to the PID control are not are not optimised or the process being controlled,
you can utilise the ollowing method to ind more appropriate parameter values:
1) Select ON/OFF control Ft=1.
2) Impose Set 1 = 10% less than the normal working temperature (as long as it is compatible
with the characteristic o the process being controlled).
3) Impose the di erential Hy1 = 3% o the value o the SET 1.
4) Start the process rom the start up and wait until the temperature control settles and cycles
regularly.
5) Monitor the process temperature (possibly with a chart recorder) recording the values at
regular intervals. In this way it is possible to determine the time between 2 successive
maximum (Tp) and maximum variations in temperature (dT) see ig.
Values or “Pb”, “Int”, “dEt”, “Cyt” will be obtained by the ollowing method: Pb = 2xdT, Int = Tp/2,
dEt = Tp/8, Cyt = Tp/20.
Other adjustments around these values can be made bearing in mind that:
•
••
• Propor ional ac ion depends on the deviation between the set point and the relative value.
•
••
• Deriva ive ac ion takes account the speed o the variations o the controlled process.
•
••
• In egral ac ion integrates the deviation o the process in time.
NOTE:
An increase o the proportional band reduces the oscillations but increases the deviation, use
“Rs” parameter to adjust the band.
An excessive decrease o the proportional band reduces the deviation but increases the system
oscillations.
A decrease in the value o “Integral action time” leads to an increased incisiveness o the integral
action and annuls the deviation at ull speed.
A small but constant deviation can lead to a large contribution o the integral action.
9. INSTALLATION AND MOUNTING
XT141C shall be mounted on vertical panel, in a 29x71 mm hole, and ixed using the special
brackets supplied.
To obtain an IP65 protection grade use the
ront panel rubber gasket (mod. RG-C).
The temperature range allowed or correct
operation is 0÷60 °C. Avoid places subject to
strong vibrations, corrosive gases, excessive
dirt or humidity. The same recommendations
apply to probes. Let air circulate by the
cooling holes.
Instruments XT141D shall be mounted on an omega DIN rail.
The temperature range allowed or correct operation is 0÷60 °C. Avoid places subject to strong
vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to
probes. Let air circulate by the cooling holes.
10. ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up
to 2,5 mm
2
. Be ore connecting cables make sure the power supply complies with the instrument’s
requirements. Separate the input connection cables rom the power supply cables, rom the
outputs and the power connections. Do not exceed the maximum current allowed on each relay,
in case o heavier loads use a suitable external relay.
11. SERIAL CONNECTIONS
All models can be connected to the monitoring and supervising system XJ500 using the serial
port. The external XJ485 serial module to inter ace the instrument with the monitoring and
supervising system XJ500 is required.
The standard ModBus RTU protocol it is used.
NOTE: Ins rumen s wi h curren or vol age inpu and 230V or 115V supply, canno be
connec ed o he XJ485 serial module.

4. A ter 10 seconds the instrument will restart working with the new parameters.
5. Remove the “Ho Key”..
NOTE the message “Err” is displayed or ailed programming. In this case turn the unit o and
then on i you want to restart the download again or remove the “Ho key” to abort the operation.
13. DIGITAL INPUT
XT141C / XT141D has 1 ree contact digital input. It is programmable in 5 di erent
con igurations by the “i1F” parameter.
13.1 INVERT THE KIND OF ACTION: HEATING-COOLING (I1F = C-H)
This unction allows to invert the regulation o the controller or both the outputs: rom direct to
inverse and viceversa.
13.2 REMOTE ON/OFF (I1F = OFF)
This unction allows to switch ON and OFF the instrument.
13.3 GENERIC ALARM (I1F = EAL)
As soon as the digital input is activated the unit will wait or “did” time delay be ore signalling the
“EAL” alarm message. The outputs status don’t change. The alarm stops just a ter the digital
input is de-activated.
13.4 SERIOUS ALARM MODE (I1F = BAL)
When the digital input is activated, the unit will wait or “did” delay be ore signalling the “bAL”
alarm message. The relay outputs are switched OFF. The alarm will stop as soon as the digital
input is de-activated.
13.5 ENERGY SAVING (I1F = HES)
The Energy Saving unction allows to change the set point1 value as the result o the SET1+ HES
(parameter) sum. This unction is enabled until the digital input is activated.
14. ALARM SIGNALS
Message Cause Ou pu s
“PFo” Probe broken or absence Alarm output ON; Output 1 and 2 according
parameters “So1” and “So2” respectively.
“PFc” Probe short circuited Alarm output ON; Output 1 and 2 according
parameters “So1” and “So2” respectively.
“HA” Maximum temperature alarm Alarm output ON; Other outputs unchanged.
“LA” Minimum temperature alarm Alarm output ON; Other outputs unchanged.
“EAL” External alarm Output unchanged.

Alarm present 5-6 open 5-6 closed
14.2 SILENCING BUZZER / ALARM RELAY OUTPUT
Once the alarm signal is detected the buzzer, i present, can be disabled by pressing any key.
The alarm relay status depends on the tbA parameter: with tbA=yES the relay is disabled by
pressing any key, with tbA=no the alarm relay remains enabled as long as the alarm lasts. The
display signal remains as long as the alarm condition remains.
14.3 ALARM RECOVERY
Probe alarms “PFo”, “PFc” start ew seconds a ter the ault in the probe; they automatically stop
ew seconds a ter the probe restarts normal operation. Check connections be ore replacing the
probe.
Max. and min. alarms “HA” and “LA” automatically stop as soon as the variable returns to normal
values.
Alarms “bAL” and “EAL” recover as soon as the digital input is disabled.
