Range rnG
Name Value range Description
rnG.L

Functions Func
Name Value range Description
tEmP 0...9999 probe temperature for O2- measurement
µ
Inputs InP.1 and InP.2
µ
Name Value range Description
InL.1
( InL.2)
-1999...9999 Input value of the lower scaling point
Dependent on sensor type, the input values can be scaled to the display values at
parameter level. Specification of the input value of the lower scaling point is in
units of the relevant electrical quantity (mA / V / Ohm), e.g. 4 mA.
OuL.1
( OuL.2)
-1999...9999 Display value of the lower scaling point
Dependent on sensor type, the input values can be scaled to the display values at
parameter level. The operator can change the display value of the lower scaling
point, e.g. 4 mA is displayed as 2[pH].
InH.1
( InH.2)
-1999...9999 Input value of the upper scaling point
Dependent on sensor type, the input values can be scaled to the display values at
parameter level. Specification of the input value of the upper scaling point is in
units of the relevant electrical quantity (mA / V / Ohm), e.g. 20mA.
OuH.1
( OuH.2)
-1999...9999 Display value of the upper scaling point
Dependent on sensor type, the input values can be scaled to the display values at
parameter level. The operator can change the display value of the upper scaling
point, e.g. 20 mA is displayed as 12 [pH].
t.F1
( t.F2)
0...999,9 Filter time constant [s]
Each input is provided with a digital (software)low-pass filter for suppression of
process-dependent interference on the input leads. The higher the value, the bet-
ter the filter effect, but the longer the input signal delay.
E.tc1
(E.tc2)
OFF, 0...100 external cold junction compensation, range dependent of temperature unit
Limit values LC, Lim1 … Lim 3
Name Value range Description
LC -1999...9999 Limit value LC. Limit value LC is the main function of the temperature monitor.
L.1
-1999...9999 Low limit value 1 ( L.1< -1999 = off)
Alarm is active when exceeding and reset with low limit value plus hysteresis.
H.1 -1999...9999 High limit value 1 ( H.1< -1999 = off)
Alarm is active when exceeding and reset with high limit value minus hysteresis.
HYS.1 0...9999 Hysteresis of limit value 1 / LC
Switching difference for high and low limit value. For limit alarm resetting, the value must
decrease by this value with high limit value and increase by this value with low limit value.
L.2
-1999...9999 lower limit 2 ( L.2< -1999 = off) (s.u.)
H.2
-1999...9999 upper limit 2 ( H.2< -1999 = off) (s.u.)
HYS.2 0...9999 Hysteresis of limit 2 (s.u.)
L.3
-1999...9999 lower limit 3 ( L.3< -1999 = off) (s.u.)
H.3
-1999...9999 upper limit 3 ( H.3< -1999 = off)(s.u.)
HYS.3
0...9999 Hysteresis of limit 3 (s.u.)
