Display in measuring mode
The measurement result is in the top line in the process menu. The absolute measured value is
not output, but the evaluation ("<" or ">") for the set hardness limit value. If there is a question
mark in front of the hardness limit, no measured value has yet been determined.
If the symbol "«" is displayed instead of the "<", ">" or "?" symbol, this indicates
brine in the soft water. As a rule, the relay for the limit value alarm also switches
with this output.
The characters means:
1.
line: hardness concentration
"<"
Soft water concentration less than the hardness limit
">"
Soft water concentration greater than the hardness limit
"?"
Soft water concentration not yet determined,
Device still in an unstable measuring state
"«"
Soft water concentration greater than raw water concentration,
caused by impermissible brine entry
2.
line: calibration status
"calib."
Raw and soft water: switch valves, device in calibration mode
3.
line: USB stick
"USB stick"
No USB stick inserted
"USB error"
USB data stick must be checked on an external PC using Explorer, refor-
matted if necessary or exchanged for an identical USB data stick from OFS
GmbH
4.
line: sensor status
(after last internal function tests)
„Sensor ok“
Sensor all right
“S↓“
Sensor with reduced quality
“S↓↓“
Sensor with impermissible quality
5.
line, left side: device and valve status
„RW“
Raw water measurement
„SW“
Soft water measurement
„MW“
Mixed water measurement in case of calibration
„Offline“
The device was set to offline mode when the potential-free external
contact was closed. There is no measurement
