Parameter
Description
14.1 Central dust sensor
Function is deactivated / activated with the number of installed central
dust sensors.
No 1…3, No = deactivated
Note!
The controller creates the maximum value via the
number of parametrised dust sensors. The monitoring
functions affect the determined maximum value.
14.2 Dust alarm max.
Global dust monitoring that runs also without valve triggering in the
background. If the set value is exceeded the alarm is triggered. If dust
delay is set (
parameter 14.10
) this is applicable here.
14.3 Dust alarm relative
Setting of absolute of relative value
No...Yes
Yes = absolute
No
= relative
14.4 Dust pre-alarm
If the set value is exceeded the alarm is triggered.
14.5 Dust main-alarm
If the set value is exceeded the alarm is triggered. If the parameter 14.9
‘Lock Dust Valve’ is activated, the valves are not triggered any more after
activation of the main alarm.
14.6 Dust check time
Time lapse of monitoring window.
14.7 Dust alarm filter
Time lapse in which an alarm is not performed before it is reported.
14.8 Dust sensor dead time
Reaction time of dust sensor. Constant value, which has a delay in time
of the dust monitoring as consequence.
14.9 Lock dust valve
Setting valve lock after triggering the main alarm.
Yes
= Valve will be disabled after main alarm is triggered
No
= Valve continues to be actuated after main alarm is triggered.
Resetting the alarm can remove the locking, however this applies to all
valves at the same time.
Yes option 1
= Dust valves will be disabled. Enabling takes place
independently from the alarm reset via the context key 'Reset Dust
Valves' (F1 or F2) in the 'Current Alarms' view (
see also chapter 15.1.1
). The function key is only visible if valves are currently
disabled. The dust-contaminated valves are displayed in the alarms list
until the function key 'Reset Dust Valves' is pressed.
Yes-Opt 2
= as yes-Opt 1 In addition to that the disabled dust valves
with the time parameter of background cleaning 'BG Cleaning Time'
(see
Parameter 6.5
) are integrated into the standard cleaning sequence, i.e.,
one dust-contaminated valve is cleaned every x minutes. The parameter
'BG Cleaning Time' can be adjusted from 0 to 1440 minutes (24 h).
The valves are able to "heal" themselves with this slow cleaning action.
That means that if the alarm is not triggered again after renewed
actuation, the valve functions correctly.
14.10 Dust chart hold
It is set how many seconds after the main alarm is triggered, the
recording on the display is stopped.
Yes
= recording is stopped (1-200).
No
= recording is not stopped and continues.
14.11 Gas speed max.
Max. gas speed during max. flow rate
14.12 Distance chamber “x”
distance chamber “x“ to sensor
15 Cleaning factors
The dust distribution within the entire filter is odd. The first and the last
chambers have mostly a higher dust load. The first and the last
chambers have mostly a higher dust load. A higher cleaning
performance can be assigned to individual chambers (and divisions) by
cleaning factors.
