GENERAL WARNING
1.1
PLEASE READ BEFORE USING THIS MANUAL
•
This manual is part of the product and should be kept near the instrument for easy and quick reference.
•
The instrument shall not be used for purposes different from those described hereunder. It cannot be
used as a safety device.
•
Check the application limits before proceeding.
1.2
SAFETY PRECAUTIONS
•
Check the supply voltage is correct before connecting the instrument.
•
Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden
temperature changes with high atmospheric humidity to prevent formation of condensation
•
Warning: disconnect all electrical connections before any kind of maintenance.
•
The instrument must not be opened.
•
In case of failure or faulty operation send the instrument back to the distributor or to “ DIXELL S.p.A”
(see address) with a detailed description of the fault.
•
Consider the maximum current which can be applied to each relay (see Technical Data).
•
Ensure that the wires for probes, loads and the power supply are separated and far enough from each
other, without crossing or intertwining.
•
In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with
inductive loads could be useful.

GENERAL DESCRIPTION
The XT151D and XT160D (DIN RAIL format) are three (XT151D) or four (XT160D) stage ON/OFF
controllers for temperature, humidity and pressure applications with direct or inverse action, user-
selectable. The analogue input type can be set by parameter between the following, according to the
model:
-
PTC, NTC;
-
PTC, NTC, Pt100, Thermocouple J, K, S;
-
4÷20mA, 0÷1V, 0÷10V.

FIRST INSTALLATION
3.1
PROBE SETTING
The pre-set probe type is written on the label of the instrument,
see picture. If it is different from the probe that has be used, set
the probe following procedure below
3.1.1 How to set the probe.
1.
Enter the programming menu by pressing the SET+
n
for 3s.
2.
Select the Pbc (Probe configuration) parameter and push the SET key.
3.
Set the kind of probe:
a.
Controller for temperature: Pt= Pt100, J = J thermocouple, c = K thermocouple, S
= S thermocouple; Ptc = PTC; ntc = ntc.
b.
Controller with current or voltage inputs: cur=4÷20mA, 0-1= 0÷1V, 10= 0÷10V
4.
Push the SET key to confirm it.
5.
Switch the controller off and on again.
NOTE: Before proceeding check and, if necessary; set with appropriate values the Minimum Set
Points (LS1 e LS2) and Maximum Set Points (US1 e US2). See also the paragraphs concerning
the programming.

REGULATIONS
4.1
3 OR 4 INDEPENDENT OUTPUTS (OUC=IND)
3 or 4 independent control stages (ouC=ind): output #1 at direct (S1C=dir) or inverse (S1C=in)
action; output #2 at (S2C = dir) direct or inverse (S2C =in) action, output #3 at (S3C = dir) direct or
inverse (S3C =in) action, output #4 (only for XT160D) at (S4C = dir) direct or inverse (S4C =in)
action.
E.I. with OUC = ind, S1C = dir (cooling), S2C = dir (cooling), S3C = dir (cooling), S4C = dir
(cooling).
4.2
3 OR 4 DEPENDENT OUTPUTS (OUC=DIP)
With dependent control stages (ouC=diP) SET2 and SET3 are related to SET1:
therefore SET2 is: SET1+SET2, while SET3 = SET1 + SET3
output #1 with direct or inverse action according to the S1C parameter; output #2 with direct or
inverse action according to the S2C, output #3 with direct or inverse action according to the S3C,
output #4 (only for XT160D) with direct or inverse action according to the S4C.
E.I. 3 outputs OUPUTS (XT151D) with ouC=diP (dependent), S1C = dir (cooling), S2C = dir
(cooling), S3C = dir (cooling).
5.
FRONT PANEL COMMANDS
SET: To display and modify target set
points; in programming mode it
selects a parameter or confirm an
operation.
TO SWITCH THE INSTRUMENT
ON/OFF: If the function is enabled
(par. onF=yES), by pressing the
SET key for more than 4s the
controller is switched OFF. To
switch the instrument on again
press the SET key.
o
UP: in programming mode it browses
the parameter codes or increases
the displayed value. Hold it pressed
for a faster change
n
DOWN: in programming mode it
browses the parameter codes or
decreases the displayed value. Hold
it pressed for a faster change
KEY COMBINATIONS:
o
+
n
To lock & unlock the keyboard.
SET +
n
To enter in programming mode.
SET +
o
To return to the room temperature display.

USE OF LEDS
A series of light points on the front panels is used to monitor the loads controlled by the instrument.
Each LED function is described in the following table.
