Type 8619
Repair and maintenance
Message dis- Meaning
played in the
"Information"
menu
"Mx:W:Temperature" The fluid temperature is out of range.
This message is displayed if monitoring
of the fluid temperature is activated on
the "Mx" module, depending on the
WARNING LOW and WARNING HIGH
thresholds defined (see section 11.7).
"W:concent.OOR" The fluid conductivity or the fluid con-
centration is outside the calculation
range.

16.3.5 "Warning" events related to a problem with the device (Orange
LED A (left) and icons
When a "warning" event related to a problem with the device is generated:
• The 4...20 mA output(s) operate normally
• The transistor outputs configured in "warning" mode switch.
Message dis- Meaning

"Information"
menu
"M0:W:Time lost" The date and time are lost.
If a time dosing cycle is set, the dosing
cycle can not be carried out. See
section 9.19.
If calibration or maintenance intervals
are set, the calibration or maintenance
reminder message is not generated. See
section 10.13, 10.15, 10.19 or 10.20.
"M0:W:ON/OFF The duration defined for the "Max-
time" ONtime" parameter in the ON/OFF
function has been exceeded (see
section 9.17).
"M0:W:Pulse x In "Pulse" mode, the volume entered for a
lim." pulse is incorrect (see section 9.26.7).
"M0:W:Pulse x In "Pulse" mode, the volume entered for a
1:1" pulse is incorrect (see section 9.26.7).

Recommended action
→ Go to the "Diagnostics" menu to read
the value of the temperature measured
(section 11.7).
→ If necessary, check whether the tem-
perature sensor is working correctly
by measuring a fluid with a known
temperature.
→ If the temperature sensor is faulty,
return it to the manufacturer.
→ If the temperature sensor is not the
cause of the problem, check the
process.
→ Make sure the fluid temperature and
the fluid conductivity are correct for the
configured calculation of the concen-
tration (section 9.29).
and displayed)
Recommended action
→ Set the date and time again (see
section 9.2).
→ Deactivate then reactivate the ON/OFF
function.
→ Enter an appropriate volume.
→ Check the K-factor.
→ Enter an appropriate volume.
→ Check the K-factor.
