Electronic Digital Thermometer with

maximum / minimum temperature log

XT11S

GENERAL WARNING

PLEASE READ BEFORE USING THIS

MANUAL

 This manual is part of the product and shall be kept near

the device for easy and quick reference.

 Check the application limits before proceeding.

SAFETY PRECAUTIONS

 Always ensure that the probe is connected to the

instrument before the power supply is connected and

turned ON.

 Check the supply voltage is correct before connecting the

instrument.

 The probe is NOT protected as a low voltage circuit

on models with 230V or 110V power supply. (12 volt

with a power transformer should be used in

applications where liquids may be a concern.)

 The instrument is designed for panel mounting and

electrical connections must be positioned inside a properly

protected enclosure/panel.

 Do not expose to water or moisture: use the instrument

only within the operating limits avoiding sudden

temperature changes with high atmospheric humidity to

prevent condensation formation.

 Warning: disconnect all electrical connections before any

kind of maintenance.

 The instrument shall never be opened.

 In case of failure or faulty operation send the instrument

back to the retailer or to "Dixell S.r.l." (See address) with a

detailed description of the fault.

 Assure that the wires for probes and for power supply are

separated and far enough from each other, without

crossing or spirals.

GENERAL DESCRIPTION

The XT11S is an electronic digital thermometer which

displays the current temperature and logs the maximum and

minimum temperatures experienced.

The maximum/ minimum temperatures can be displayed at

the touch of a button and reset if required. (Requires an

additional switch)

INSTALLATION 230V OR 115V (FIG.1)

The instrument is equipped with fast-on type spade terminals

with probe connections separated from the power supply

connections. To install the instrument proceed as follows:

WeissInstruments_XT11S_05152013_mm

Make a 59x25.5 mm (1.01"x2.32") hole in a panel with

maximum thickness of 2.7mm.

Take the instrument from the box and place it in the

hole until the side flaps click, which means they are

locked.

Disconnect the power supply from the board by

means of the panel switch (P1 in Fig.1)

Place the probe where it has to measure the

temperature.

Connect the probe terminals to the 2.8mm (.110") fast-

ons as indicated.

Connect the power supply cables to the 6.3mm (.25")

fast-ons.

If possible, the manufacturer suggests connecting the

phase (L) to the fast-on on the right and neutral (N) to

the fast-on on the left as indicated.

At this stage the board can be connected to the power

supply once more.

PROBE SUBSTITUTION (FIG.1)

Disconnect the power supply on the board

where the instrument is positioned, by means of

the panel switch (P1 in Fig.1)

2. Remove the power supply spade-on.

3. Disconnect the instrument and the probe.

°C/°F CHANGE

Use the black jumper to change from °C to °F and vice

versa. With the jumper closed the °F values are displayed,

without jumper the °C values are displayed.

TEMPS (FIG.2)

In order to display the maximum and minimum values on the

instrument, use the S1 Class II approved type push button,

normally open. (NOT SUPPLIED). ORDER P/N: PB-KIT

Before carrying out the connections, disconnect the

power supply on the board where the instrument is

positioned.

Connect the push button in parallel with the probe as

shown in Fig.2.

TEMPERATURE LOGGED

Fuse

Once the button for minimum & maximum temperature

63mA

display has been connected, proceed as follows:

Maximum temperature display:

Press and hold the push button (S1) until the display

reads "HI".

Release S1 and the highest temperature recorded

since the last reset will be displayed for 3 seconds.

Minimum temperature display:

Press and hold the push button (S1) until the display

reads "LO".

Release (S1) and the lowest temperature recorded

since the last reset will be displayed for 3 seconds.

Probe offset value display:

Press and hold the push button (S1) until the display

reads "PO".

Release S1 and the probe offset value will be displayed

for 3 seconds.

Maximum /minimum temperature reset

Press and hold the push button (S1) until the display

reads "rE".

Release S1 and the display will flash "rE" for 5 seconds.

While the display is flashing press the push button and

the max & min temperature will be erased.

Power on and power failure warning:

XT11S

When the power supply is turned on and after any power

failure, when the maximum and minimum set values are

visualised, the display flashes. This is to warn the user that

there has been an interruption to the power supply.

To restore normal operation, follow the same procedure that

is used for re-setting the maximum/minimum memory. (See

Maximum /minimum temperature reset).

MAINTENANCE AND CLEANING

Instruments do not require particular maintenance. To clean

frontal frame, just use a soft moist cloth and avoid using any

strong detergent or solvent.
