Notes :
−
All blocks, except « INFO » and « SECUR », can be protected (see § 7.7.2) and so can appear or
not in the diagram described above.
−
The block « M.CARD » appears only if the memory card is inserted.
Warning ! The programs which enable the functioning of the device are contained into the
block « PROGRAM ». Thus, all modifications can induce a dysfunction of the device. So, it is
advised to not enter into this block.
In case of a configuration error, reconfigure the device with the memory card (see § 5.1) or
contact your distributor.

Alarm Block "ALARME"
Whatever the current view is, this block appears.
The
ALARME
code appears on the lower display.
Pressing the key
↵
, you scroll through the following values (n = 1 to 4):
ALR.1 :
This variable represents the alarm N° 1 threshold.
This variable is adjustable within the selected measurement range.
HYS.1 :
HYS.1 adjustable on the whole measurement range (in engineering unit).
The device can drive up to four alarms (as much ALR.n and HYS.n to be adjusted).
The thresholds that control some programs variables are entered according to the display limits. In
this case, pressing simultaneously on the two keys
↑
and
↓
, you change the decimal point position.
REMIND :
Alarms 1 and 2
Viscosity
Alarms 3 and 4
Temperature (see § 6.4 ).
7.4.
Filter block "FILTRE"
Whatever the current view is, this block appears.
The FILTRE code appears on the lower display.
You can define a filter for each measuring input (see § 6.3).
Pressing the key
↵
, you scroll through the following values (n = 1 to 6) :
TAU.En
"First order" type filter.
Adjustment of the power from 0 to 100%.
BAND.En
Adjustable from 0 to 100%. The filtering will be active only in the defined band on each
side of the current process variable.
Any instantaneous variation of the process variable higher than the band will not be
affected by any filtering.
The filtering power is linear within the band (at 0 on the band limit and at the maximum
to the point).
REMIND :
See § 6.3 for the inputs.
GRD.Sn
Limitation of the evolution speed of the installed analog outputs (see §6.6).
Adjustable from 0.1 to 100%/seconds (inactive above 99%).
REMIND :
See § 6.6 for the outputs.
