Frequently Asked Questions - TR2430 IFM

How to set the high set point (SP1)?

In Display mode, select parameter SP1 with the Mode/Enter button. Press Set until the value flashes, then adjust with Set. Confirm with Mode/Enter.

What does display 'OL' mean?

Display 'OL' indicates a temperature too high exceeding the measuring range. Check the probe and fluid.

How to clear the max/min temperature memory?

In Display mode, display HI or Lo with Mode/Enter. Press Set until '...' appears, then briefly press Mode/Enter to clear.

What is the difference between Hno and Hnc?

Hno (hysteresis / normally open) switches when the temperature exceeds SP1, and Hnc (normally closed) switches when the temperature falls below rP1.

How to configure the analog output as 4-20 mA?

In parameter AOU, select 'I' for 4...20 mA or 'U' for 0...10 V. Confirm with Mode/Enter.

The red LED does not light up, what to do?

Check the power supply (20...30 V DC) and the wiring. If the LED remains off, the device may be in programming mode or defective. Consult the wiring diagram.

Can I use a standard PT100 probe?

Yes, the device is designed for PT1000 probes (385 μA). Check compatibility with your probe, especially the temperature coefficient.

How to lock the device to prevent changes?

In Run mode, press both buttons simultaneously for 10 seconds. The display briefly turns off. Repeat to unlock.

What does flashing 'Err' mean?

This indicates a missing probe, a probe fault or short-circuit, or a wire break. Check the connection and probe.

What is the display resolution?

The resolution is 0.5 °C or 0.5 °F for the display and switching output, and 0.125 °C / 0.23 °F for the analog output.

1. Controls and visual indication

①	Indicator for display unit	OFF = indication in °C; ON = indication in °F
②	7-segment display	display of the system temperature, display of parameters and parameter values

2. Functions and features

• The unit detects current system temperature from temperature sensors TS or TT,
• shows the current system temperature on its display (in ^ C or ^ F ),
• and generates 2 output signals according to the set output configuration.

output 1	output 2
hysteresis function / N.O. (Hno)	analog 4 ... 20 mA (I)
hysteresis function / N.C. (Hnc)
window function / N.O. (Fno)	analog 0 ... 10 V (U)
window function / N.C. (Fnc)

Measuring range

°C -40 ... +150
	-40 ... 302°F

Hysteresis:

The hysteresis keeps the switching state of the outputs stable if the system temperature varies about the preset value.

When the system temperature is rising, the output switches when the switch-on point has been reached (SP1); when the system temperature is falling again, the output switches back when the switch-off point (rP1) has been

reached. The hysteresis can be adjusted: First the switch-on point is set, then the switch-off point with the requested difference.

Window function:

The window function enables the monitoring of a defined acceptable range.

When the system temperature varies between the switch-on point (SP1) and the switch-off point (rP1), the output is switched (window function/NO) or not switched (window function/NC).

The width of the window can be

set by means of the difference between SP1 and rP1. SP1 = upper value, rP1 = lower value.

3. Operating modes

Run mode:

(Normal operating mode)

When the supply voltage has been applied, the unit is in the Run mode. It monitors and switches the transistor output according to the set parameters.

The value of the analog output depends on the system temperature. The LED display indicates the current system temperature, the red LED indicates the switching state of the transistor output.

Display mode:

(Indication of parameters and the set parameter values)

When the "Mode/Enter" button is pressed briefly, the unit passes to the Display mode which allows parameter values to be read. The internal sensing, processing and output functions of the unit continue as if in Run mode.

• The parameter names are scrolled with each pressing of the "Mode/Enter" button.
• When the "Set" button is pressed briefly, the corresponding parameter value is displayed for 5 s. After another 5 s the unit returns to the Run mode.

Programming mode:

(Setting of the parameter values)

The unit passes to the programming mode when after the selection of a parameter value (Display mode) the "Set" button is pressed until the display of the parameter value is changed. Internally the unit remains in the operating mode. It continues its monitoring function with the existing parameters until the change has been terminated.

You can change the parameter value by pressing the "Set" button and confirm it by pressing the "Mode/Enter" button. The unit returns to the Run mode when no button has been pressed for 5 s.

4. Adjustable parameters

menu sstructure: see page 3

SP1	Switch-on point: Upper limit value at which the output changes its switching status.
		setting range in steps of
	°C	-39.5 ... +150 0.5
		-39 ... +302 1°F
-RP1	Switch-off point: Lower limit value at which the output changes its switching status.
		setting range in steps of
	°C	-40 ... +149.5 0.5
		-40 ... +301 1°F
	rP1 is always lower than SP1. The unit only accepts values which are lower than SP1.Changing the switch-on point also changes the switch-off point (the hysteresis remains constant).If the hysteresis is higher than the new switch point, it is automatically reduced (rP1 is set to the minimum setting value).
OU1	Configuration of the switching output4 switching functions can be set:Hno = hysteresis / normally openHnc = hysteresis / normally closedFno = window function / normally openFnc = window function / normally closed
ASP	Lower end of analog outputMeasured value for which the output signal is 4 mA / 0 V.
		setting range in steps of
	°C	-40 ... +140 0.5
		-40 ... +284 1°F
AEP	Upper end of analog outputMeasured value for which the output signal is 20 mA / 10 V.
		setting range in steps of
	°C	-30 ... +150 0.5
		-22 ... +302 1°F
	Minimum distance between ASP and AEP = 10°C / 18°F
AOU	Output function for the analog output 2 options can be selected: I = 4 ... 20 mA / U = 0 ... 10 V
di5	Setting of the display 4 options can be selected: °C = display in °Celsius °F = display in °Fahrenheit r°C = display in °Celsius (inverted) r°F = display in °Fahrenheit (inverted) Select the display unit before setting the switch points (SP1, rP1) and the limits for the analog output signal (ASP, AEP). This avoids rounding errors generated internally during the conversion of the units and enables exact setting of the values. Units are delivered from the factory with dis = °C
CAL	Calibration offset The internal measured value (operating value of the sensor) is offset against the real measured value.
		setting range in steps of
	°C	-9.9 ... +9.9 0.1
		-17.5 ... +17.5 0.5°F
Hi Lo	Min-Max memory for system temperature • Hi: displays the highest measured temperature • Lo: displays the lowest measured temperature Erase the memory: - Press the "Mode/Enter" button until HI or Lo is displayed. - Press the "Set" button and keep it pressed until "-" is displayed. - Then press the "Mode/Enter" button briefly. It is recommended to erase the memory as soon as the unit starts working under normal operating conditions.

7. Programming

1	Mode/Enter Set	→SP1	Press the Mode/Enter button several times until the respective parameter is displayed.
2	Mode/Enter Set	→70	Press the Set button and keep it pressed. The current parameter value is indicated for 5 s, then the value is increased* (incremental by pressing briefly or scrolling by holding pressed).
		→100
3	Mode/Enter Set	→5P1	Press the Mode/Enter button briefly (= acknowledgement). The parameter is displayed again, the set parameter value becomes effective.
Wait 5 s (the unit passes to the operating mode and the current measured value is indicated again), or start again with step 1 to program other parameters.

*Decrease the value: Let the display of the parameter value move to the maximum setting value. Then the cycle starts again at the minimum setting value.

Locking / unlocking:

The unit can be electronically locked to prevent unwanted adjustment of the set parameters: Press (in Run mode) both pushbuttons for 10 s. As soon as the indication goes out the unit is locked or unlocked. Units are delivered from the factory in the unlocked state.

8. Installation and set-up / operation

Check the safe functioning of the unit. The operation is maintenance-free. Failure indication:

OL	= too high a temperature
UL	= too low a temperature
SC 1	(FLASHING) = short-circuit in the switching output; the output is switched off.

Failure indication (cont.):

Err	(FLASHING) = no temperature sensor connected, fault or short circuit in the temperature sensor, wire break, evaluable range
