6.8.4.1 Monitoring and service mes-
sages
The components of the unit which wear due
to operational reasons, including the steam
cylinder(s), are monitored continuously when
the unit is in operation. When a limit value is
reached, the corresponding service message
is displayed with reference to the cylinder.
The service messages need to be reset after
component replacement or cylinder mainte-
nance.
The following
service messages
are set:
Steam amount
A steam amount in kg is specified in the
"Steam amount_service" parameter and after
this is reached, the message "Steam
amount_counter" is issued.
In case of double cylinder units, the parame-
ter entry applies to both cylinders. The ser-
vice message differentiates between cylinder
1 and cylinder 2.
After the service has been carried out, the
message has to be reset with "Service
reset_cyl. 1" or "Service reset_cyl. 2" (or
both).
For the assessment of the remaining steam
amount until the next service is required, the
reading values "Steam
amount_until_service_cyl. 1" and
"Steam_amount_until_service_cyl. 2" (only
for double cylinder units) are used.
Main contactors
For main contactors, the maximum number
of switching cycles is specified by the manu-
facturer. When a limit value is reached, the
corresponding service message is displayed.
The main contactor must then be replaced
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 using the "Kx_switching
cycles_until msg" (x = 1...5) reading values.
Monitoring
The FlexLine control continuously monitors
the proper functionality of the electrodes
(only for ELDB), the blow-down pump(s) and
the solenoid valve(s). If the preset functional-
ity alarm thresholds are exceeded, messages
regarding the status
•
of the
electrodes
(only for ELDB)
("Warning_cyl. full") or
•
the
blow-down pump(s)
("Warning_pump") or
•
the
solenoid valve(s)
("Warning_valve")
are created.
Three sensitivity values can be selected for
each of the alarm thresholds, where "Sensi-
tivity 3" (factory setting) triggers the warning
messages at the earliest point.
After the cause is resolved (e.g. cleaning the
input filter of the solenoid valve when a
"Warning_valve" message appears), the
warning message disappears.
The three above-mentioned messages can
also be turned off (see subsequent Section
"Table of service parameters", parameters
22, 23, 24).
