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, userselectable. 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

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).

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.

4. 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).

AOC Analog output configuration: (only for models with analog output)

AOC=Pb Probe reading. The analog output parameters LAO and UAO are indipendent and correspond to the absolute read-out probe signal.

AOC=Er Probe - Set Point1. The analog output parameters LAO and UAO are related to the difference between measurement of the probe and Set Point 1.

LAO Lower analog output limit: (only for models with analog output) minimum value of temperature associated to the 4mA analog output. This value can be absolute or relative to the

Set Point 1 by setting the AOC parameter.

UAO Upper analog output limit: (only for models with analog output) maximum value of temperature associated to the 20mA analog output. This value can be absolute or relative to the

Set Point 1 by setting the AOC parameter.

SAO Analog output safety with probe fault: (only for models with analog output) determines what state the analog output should assume when the probe is faulty:

SAO = oFF; analog output = 4mA

SAO = on; analog output = 20mA.

DIGITAL INPUT

HES Set point 1 changes during the Energy Saving cycle: (Down Sc./Full Sc.) sets the variation of the set point 1 during the Energy Saving cycle.

4. 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.

5. ELECTRICAL CONNECTIONS

The instruments are provided with screw terminal block to connect cables with a cross section up to 2,5 mm 2 . 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.

6. 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.

7. HOW TO USE THE HOT KEY

7.1 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 o key; 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 o key if you want to restart the upload again or remove the “Hot key” to abort the operation.

7.2 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.

8.3 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 deactivated.

8.4 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 deactivated.

8.5 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.

9.2 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.

9.3 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.
