1. 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.
2. 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.
3. 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+ nfor 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.
4. REGULATIONS
4.1 3 OR 4 INDEPENDENT OUTPUTS (OUC=IND)

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).

8. INSTALLATION AND MOUNTING
Instruments XT160D, XT151D, shall be mounted on an omega DIN rail.
The temperature range allowed for 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.
9. ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up to
2,5 mm2. Before connecting cables make sure the power supply complies with the instrument’s
requirements. Separate the input connection cables from the power supply cables, from the outputs
and the power connections. Do not exceed the maximum current allowed on each relay, in case of
heavier loads use a suitable external relay.
10. SERIAL CONNECTIONS
All models can be connected to the monitoring and supervising system XJ500 using the serial port.
The external XJ485 serial module to interface the instrument with the monitoring and supervising
system XJ500 is required.
The standard ModBus RTU protocol it is used.
11. HOW TO USE THE HOT KEY
11.1 HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)
1. Program one controller with the front keypad.
2. When the controller is ON, insert the “Hot key” and push okey; the "uPL" message
appears followed a by flashing “End”
3. Push “SET” key and the End will stop flashing.
4. Turn OFF the instrument remove the “Hot Key”, then turn it ON again.
NOTE: the “Err” message is displayed for failed programming. In this case push again okey if you
want to restart the upload again or remove the “Hot key” to abort the operation.
11.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY
(DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a programmed “Hot Key” into the 5 PIN receptacle and then turn the Controller ON.
3. Automatically the parameter list of the “Hot Key” is downloaded into the Controller memory,
the “doL” message is blinking followed a by flashing “End”.
4. After 10 seconds the instrument will restart working with the new parameters.
5. Remove the “Hot Key”..
NOTE the message “Err” is displayed for failed programming. In this case turn the unit off and then
on if you want to restart the download again or remove the “Hot key” to abort the operation.
12. DIGITAL INPUT
The controllers have 1 free contact digital input. It is programmable in 5 different configurations by
the “i1F” parameter.
12.1 INVERT THE KIND OF ACTION: HEATING-COOLING (I1F = C-H)
This function allows to invert the regulation of the controller for both the outputs: from direct to
inverse and viceversa.
12.2 REMOTE ON/OFF (I1F = OFF)
This function allows to switch ON and OFF the instrument.
12.3 GENERIC ALARM (I1F = EAL)
As soon as the digital input is activated the unit will wait for “did” time delay before signalling the
“EAL” alarm message. The outputs status don’t change. The alarm stops just after the digital input is
de-activated.
12.4 SERIOUS ALARM MODE (I1F = BAL)
When the digital input is activated, the unit will wait for “did” delay before signalling the “bAL” alarm
message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-
activated.
12.5 ENERGY SAVING (I1F = HES)
The Energy Saving function allows to change the set point1 value as the result of the SET1+ HES
(parameter) sum. This function is enabled until the digital input is activated.
13. ALARM SIGNALS
Message Cause Outputs
“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.
“bAL” Serious external alarm Output OFF.
13.1 ALARM RELAY STATUS
Status of the instrument XT151D
AS = CL AS= oP
Instrument off 13-14 open 13-14 open
Normal operating 13-14 open 13-14 closed
Alarm present 13-14 closed 13-14 open
13.2 SILENCING BUZZER / ALARM RELAY OUTPUT
Once the alarm signal is detected the buzzer, if present, can be disabled by pressing any key.
XT151D: 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.
13.3 ALARM RECOVERY
Probe alarms “PFo”, “PFc” start few seconds after the fault in the probe; they automatically stop few
seconds after the probe restarts normal operation. Check connections before 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.
