6 Commissioning / Shutdown
69
6.8 Setting service warnings
Service warnings 1 and 2 draw attention to the need for regular servicing. The plant
operator can define service warnings as required, e.g.
• Service warning 1 → Check probe
• Service warning 2 → Remove and clean probe
The appropriate cycle times can be pre-defined in the range of 1 to 65535 hours by
means of parameters 1260 and 1261.
The factory setting is with service warnings deactivated.
6.9 Practical information for operation
6.9.1 Measurement with pronounced pressure surges at the measuring point
If the display jumps dramatically, damping can be increased (i.e. by increasing the
time constant of measurement value integration) and the display settled using the
display and operating unit or the remote display software (optional extra) parameter
360 for O

display, P370 for CO
e
display - Operation access level. However, this slows
down the rate at which the display reaches a final value.
NOTE:
Increased damping also results in the artificial slowing down of the measurement
signal.
6.9.2 Shutdown, switching on and off
In the case of longer shutdowns of approx. three months or more, we recommend
switching off the measurement. To prevent damage to the probe, it must be removed.
For shorter shutdowns, however, we recommend that you leave the measurement
running.
6.10 Taking out of operation
To reliably exclude the possibility of damage to the KS1-DK combination probe, the
latter must be removed before taking the measurement out of operation, or
immediately after the mains voltage is switched off.
CAUTION:
Remove the probe before taking the measurement out of operation.
Danger, hot!
NOTE:
Once removed, the KS1-DK combination probe can be stored for an unlimited
duration. The zirconium dioxide measuring element only becomes worn during
operation (measuring cell at operating temperature). This is also the case if the probe
has already been in operation.
