Note
In the parameter setting mode the currently adjusted value is indicated by both seven-
segment LED displays.
When the housing is open:
Setting the temperature limit T
MAX
(°C)
Use the three pushbuttons to set the temperature limit T
MAX
(°C).
The pushbuttons have the following functions:
n
Pushbutton to the right: setting in increments of 1°C
n
Pushbutton in the middle: setting in increments of 10°C
n
Pushbutton to the left: +/– (increase/decrease)
Upon application of the supply voltage and during operation, the adjusted temp. limit T
MAX
(°C) and the
actual value are indicated.
Press any of the three pushbuttons to switch to the parameter setting mode of the TRV 5-40. Both
seven-segment LED displays show the adjusted limit value T
MAX
(°C) and all digital points are flashing.
The adjusted limit T
MAX
(°C) remains valid until the setting of the new value is finished.
If no other pushbutton is pressed within 10 seconds the temperature transmitter switches back to
normal operation.
Increasing the limit value
When you are in the parameter setting mode press the right (increments of 1°) and/or middle
(increments of 10°C) pushbutton to adjust the desired new limit T
MAX
(°C).
To increase or decrease the setting use the left pushbutton (+/–).
Decreasing the limit value
When you are in the parameter setting mode first press the left pushbutton (+/–). Then press the
right (increments of 1°) and/or middle (increments of 10°C) pushbutton to adjust the desired new limit
T
MAX
(°C).
To increase or decrease the setting use the left pushbutton (+/–).
After you have finished the new setting do not press a pushbutton for 10 seconds. The new limit value
T
MAX
(°C) is then accepted by the temperature transmitter TRV 5-40 and the equipment switches back
to normal operation. The new limit value T
MAX
(°C) and the actual value will now be indicated.
Please write the new temperature limit T
MAX
(°C) on the name plate.
