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.

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 outputs according to the set parameters..
The LED display indicates the current system temperature, the red LEDs indicate the switching state of the transistor outputs.
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.
Installation
Connect a temperature sensor to the unit and fix it to the process connection.
Electrical connection
The unit must only be connected by an electrician.
The national and international regulations for the installation of electrical equipment must be observed.
Voltage supply to EN50178, SELV, PELV.
Disconnect power before connecting the unit.
Wiring:
$$ 2 = \text {O U T 2} $$
$$ 4 = \text {O U T 1} $$
Core colours of ifm sockets: 1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black); n.c. = not connected.
Programming of complementary outputs:
output 1: = Hno, output 2: = Hnc, SP1 = SP2 / rP1 = rP2.
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 | →SP1 | 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 both pushbuttons for 10s. Indication goes out briefly (acknowledgement of locking / unlocking).
Units are delivered from the factory in the unlocked state.
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 |
| SC1 | (FLASH) = short-circuit in switching output 1/2; the respective output is switched off. |
| SC2 | |
| Err | (FLASH) = no temperature sensor connected, fault or short circuit in the temperature sensor, wire break, evaluable range |

| SP1 SP2 | Switch-on point Upper limit value at which the output changes its switching status. | ||
| - P1 - P2 | Switch-off point Lower limit value at which the output changes its switching status. rPx is always lower than SPx. The unit only accepts values which are lower than SPx. 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 (rPx is set to the minimum setting value). Setting ranges: | ||

| 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. | ||
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 (SPx); when the system temperature is falling again, the output switches back when the switch-off point (rPx) 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 (SPx) and the switch-off point (rPx), 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 SPx and rPx. SPx = upper value, rPx = lower value.
