N.B.: Setting this parameter to zero corresponds to disable the alarm
(POS. 4.8) Frequency output value in case of failure
Setting of the frequency value to assign to the on/off output in one or more of the following cases:
Empty pipe ; Coils interrupted ; ADC error
The allowed range is from 0 to 125% of the frequency full scale value. Although there are no specific
rules regulating cases like this one, it would be convenient to use the failure information as follows:
0% Hz ≤ frequency ≤ 100% f.s.: normal working range;
100% f.s. < frequency ≤ 110% f.s.: overflow, measure above the 100% of the f.s.;
115% f.s. ≤ frequency ≤ 125% f.s.: hardware alarm condition.
(POS. 4.9) Batch safety timer
With this function is possible to set a maximum time for the batch ; over this time will be generate an
alarm.
This function is useful when you need to control one or both of the following conditions:
batch valve open and flow rate is nul
batch valve closed and flow rate different to zero
When this alarm is activated, the batch operation is abortedand the power supply of the valve is cut off.
The possible values for the function are: 0 (disabled) to 25.5 seconds and is active only if one or more
of the batch functions are enabled.
(POS. 5.1-5.2-5.3-5.4) Totalise + reset enable/disable
To reset the totalisers from the keyboard it is necessary to enable the function 8.7 (modify tot.) and one
of the functions 5.1 to 5.4.
From any visualisation page, proceed in the following mode:
Have a long press on key "ENTER"; Set the L2 CODE if required and then push key "ENTER"
Position the cursor on value field to modify the numerical value (it is possible to only modify the
enabled totalizer) then push key "ENTER" to confirm the modified value
Position the cursor on "RESET TOTALIZ.?" Push key "ENTER" and then have a long press on key
"ENTER" to confirm or any other key to abort the operation.
If function 8.7 is disabled the totalizer can be reset by having a long press on key "ENTER" from the
visualization page; At the request "RESET TOTALIZ.?" press key "ENTER" then have a long press on
key "ENTER" to confirm or any other key to abort the operation.
(POS.5.7) "Autozero" calibration external command enable/disable
When this function is enabled, applying a voltage on the on/off input terminals makes the transmitter
perform an autozero calibration cycle. ATTENTION: if the voltage pulse is lower than 1 sec., the
transmitter performs a calibration cycle to compensate possible thermal variations. If the voltage pulse
is higher than 1 sec, the transmitter performs a zero calibration of measure. This function
enables/disables the automatic zero calibration. To perform the sensor it is absolutely necessary the
sensor is full of liquid and that the liquid is perfectly staying still. Even very small movement of the
liquid may affect the result of this function, and, consequently, the accuracy of the system.
(POS. 5.8) Range change external command enable/disable
When this function is enabled, applying a voltage on the on/off input terminals makes the transmitter
switch to the second measuring range (Fs2).
N.B.: the autorange doesn't allow using the manual change range (see pos. 3.7)
(POS.5.10) Functions assigned to input 2
To choose the function to associate to input 2 The functions are listed in the table below.
