8.4 Parameters:
Name Description
SP1/SP2
rP1/rP2
Set points [SP1] / [SP2] and reset points [rP1] / [rP2]�
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 = 0 %; process value in tap water = 100 %
Setting range [SPx]: 4���98 %; step increment: 1 %
Setting range [rPx]: 2���96 %; step increment: 1 %; minimum hysteresis: 2 %
Reference values:
Aqueous / water-based
media:
SPx = 62 %, rPx = 54 %
(factory setting LMTx0x)
Media with low water content: SPx = 35 %, rPx = 29 %
(factory setting LMTx2x)
Oils, fats, powdery media: SPx = 8 %, rPx = 5 %
(factory setting LMTx1x)
ou1
ou2
[ou1] / [ou2]: output function for OUT1/OUT2
- [Hno] = hysteresis function/NO
- [Hnc] = hysteresis function/NC
- [Fno] = window function/NO
- [Fnc] = window function/NC
Parameter [ou1] also provides the option [tch]:
- [tch] = configure pin 4 as input for the teach signal (→ 6),(→ 8.8)
FOU1
FOU2
Behaviour of the outputs OUT1 / OUT2 in case of a fault
- [OFF] = output opens in case of a fault (factory setting)
- [On] = output closes in case of a fault
dFo Delay time of the outputs in case of a fault
Setting range 0���5 s; step increment 0�2 s
dS1*
)
dS2*
)
Switching delay for OUT1 / OUT2
Setting range 0���10 s; step increment 0�2 s
*) Parameter [dSx] is not available for LMT100, LMT110 and LMT121�
dr1
dr2
Switch-off delay for OUT1 / OUT2
Setting range 0…10 s, step increment 0,2 s
P-n Output polarity for the outputs (PnP or nPn)
[SPx] must be higher than [rPx]� If [SPx] is set to a value below [rPx],
this is rejected�
