9.2.4 Adjustable parameters and system commands
Parameter
uni�T
Selection of the temperature unit:
[°C] = temperature is displayed in °C (degrees Celsius)
[°F] = temperature is displayed in °F (degrees Fahrenheit)
P-n
Set output logic for the switching outputs:
[PnP] = positive switching
[nPn] = negative switching
SEL2
Allocation of switching output OUT2 to the process value:
[LEVL] = level
1)
[TEMP] = temperature
LED mode
Switching state display via LEDs
(→ 8)
:
[OUT1] = The two yellow LEDs (LED1 and LED2) indicate the
switching status of output OUT1�
[OUT1+OUT2] = LED1 indicates the switching status of OUT1
and LED2 the switching status of OUT2�
ou1
Output configuration for switching output OUT1 (level)
[Hno] = hysteresis function / normally open
[Hnc] = hysteresis function / normally closed
[OFF] = output OFF (high impedance)
ou2
Output configuration for switching output OUT 2 (level /
temperature)
[Hno] = hysteresis function / normally open
[Hnc] = hysteresis function / normally closed
[Fno] = window function
2)
/ normally open
[Fnc] = window function
2)
/ normally closed
[OFF] = output OFF (high impedance)
SPx - LEVL
Switch point 1 or 2 for level�
[SPx] must be greater than [rPx]� If [SPx] is set to
a value below [rPx], this is rejected by the device
software�
The values for [SPx] / [rPx] are set in per cent of the maximum
process value�
The process value is defined as follows:
Process value in air (not predamped): approx. 0 %
Process value in tap water = approx. 100 %
3)
rPx - LEVL
Switch-off point 1 or 2 for level
