5.8.4.1 Monitoring and service mes-
sages
The wear components of the unit and the sta-
tus of the steam cylinder(s) are monitored
continuously when the unit is in operation.
When a limit value is reached, the corre-
sponding service message is displayed with
reference to the cylinder. The service mes-
sages need to be reset after component
replacement or cylinder maintenance.
The following service messages are imple-
mented:
Steam volume
A steam volume in kg is specified in the
"Steam_volume_service" parameter and
after this is reached, the message "Steam
volume counter" is issued. In case of double
cylinder units, the parameter entry applies to
both cylinders. The service message differ-
entiates between cylinder 1 and cylinder 2.
After the service has been carried out, the
message has to be reset with "Reset_cyl. 1"
or "Reset_cyl. 2" (or both).
For the assessment of the remaining steam
volume until the next service is required, the
read values "Steam_volume_to_service_cyl.
1" and "Steam_volume_to_service_cyl. 2"
(only for double cylinder units) are used.
Main contactors
For main contactors, the maximum number of
operating cycles is specified by the manufac-
turer. When a limit value is reached, the cor-
responding service message is displayed.
The main contactor must then be changed
and the message has to be reset by setting
the "Main_contactor Kx_Reset" (x = 1...5)
parameter.
When the service message was triggered for
one of the main contactors, it is advisable to
check the meter reading for the remaining
main contactors.
Monitoring
The FlexLine control permanently monitors
the performance capabilities of the elec-
trodes (ELDB only), of the blow-down
pump(s), and of the solenoide valve(s).
When preset functionality warning thresholds
are exceeded, messages are generated with
respect to the current state of:
•
Electrodes (ELDB only),
(„Warning_cyl._full“)
•
Blow-down pump(s) („Warning_pump“)
•
Solenoid valve(s) („Warning_valve“)
Three sensitivity values can be selected for
each of the alarm thresholds, where "Sensi-
tivity 3" triggers the warning messages at the
earliest time. The highest sensitivity thresh-
old is set ex-factory.
After the condition for triggering the warning
has been resolved (e.g. by cleaning the sole-
noide valve intake strainer), no further warn-
ing is issued. The warning messages can
also be turned off (s. parameters 22, 23 and
24 in the table following hereunder).
