3 Analog inputs
• Current CO
2
measured value
• Furnace temperature
• Pressure level in gas circuit
• pH value in stripping vessel
Switch inputs
Switching status of the switch inputs
Ix = 0 = OFF
Ix > 0 = ON
PE = Peltier element
WA = Water pressure alarm
SB = Standby
LM = Leak detector
O2 = Gas pressure sensor
MEASUREMENT ON/OFF = Indicates
whether measuring operation is still
active in the background or not.
If you test the inputs when background
operation is active (e.g.: jumpering the
leak detector), the appropriate error
response measures are triggered by the
program.
Terminate the measurement operation
(Prog/Test/Measurement off) before
physically testing the input signals.
