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 °C
n
Pushbutton in the middle: setting in increments of 0°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 0 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 °) and/or middle
(increments of 0°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 °) and/or middle (increments of 0°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 0 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.
