3.8 Checking the Settings
Press left until SETUP is displayed, then
open LIMIT ALARMS - CONCENTRATION
3.8.5 Setting Concentration Alarms
Four concentration limits can be set for each
channel:
"Lo" and "Hi" enframe the expected gas
concentration,
"LoLo" equals or is below "Lo",
"HiHi" equals or is above "Hi".
See the gure to the left for an explanation.
If you enter values for any threshold, the
above given order has to be considered. A
message is displayed, if an entered value
does not comply with this condition.
Note!
If concentration alarms are not being used,
continue with 3-25.
Should the measured concentration go be-
yond one of the threshold levels (areas B, C,
D & E in the gure), a message is displayed in
the message line of the measurement display,
the NAMUR pictogram appears (bell) and a
corresponding digital output is activated, if
assigned.
A hysteresis avoids oscillating alarms in
case the concentration is uctuating around
a threshold.
