MODULE LAYOUT
Weight: 170 g; Enclosure: Self-extinguishing PC/ABS material, black.
BUTTON POSITION
4-6-8-11-DIGIT DISPLAY
OPERATION DESCRIPTION
The measurement of the digital input frequency or the totalizer value is
translated into an analogue or digital output signal.
The frequency value or alternatively the totalizer value can also be viewed
via the display; in the 11-digit model (4 + 7) both values can be displayed
simultaneously (4 digits: frequency value, 7 digits: totalizer value). The
values are also available via MODBUS-RTU protocol from the RS485 port (via
optional board).
Setting mode:
All the parameters of the instrument can be set via the Programming Menu or
RS485 (via optional board). The alarm thresholds can also be set quickly via
the specific Quick Alarm Menu. The dedicated Easy Setup software for
programming/ configuring the module was also developed (see
www.seneca.it ).
Retransmission mode:
The instrument accepts the following retransmission modes:
Analogue output: The measurement of the frequency of the digital input is
translated into an analogue output signal (current or voltage).
Digital output: The output generates an impulse every time the
totalization is increased or decreased. A pulse of duration ≥ ~ 100 ms is
generated. The output follows the totalizer up to the maximum value of
approximately 4.7 Hz. As the counting frequency increases (up to the maximum
value shown above), pulses are gradually lost until an output is obtained
always at a low logic level. The output is normally high.

Alarms on frequency or totalizer measurement (optional board):
Two alarms can be activated on the measurement of the frequency of the digital
input signal or on the totalizer threshold values, each of which, if enabled,
can be configured as follows:
- Alarm on the minimum threshold.
- Alarm on the maximum threshold.
- Alarm on the minimum held threshold (does not automatically reset).
- Alarm on the maximum held threshold (does not automatically reset).
- Alarm on the totalizer threshold value (does not reset automatically).
For each alarm it is possible to set threshold and hysteresis. For the
totalizer alarm, the hysteresis is not considered. If the alarm is maximum the
reset value is Threshold-Hysteresis, if it is minimum the reset value is
Threshold + Hysteresis. The status of the alarms can be viewed via the two
LEDs on the front panel and from the relays (if the optional board is used).
The relays switch status when the alarm occurs and return to the initial state
when it is reset (if held). The alarms held are reset in normal operation by
pressing the UP + OK/MENU keys for a few seconds. For the totalizer alarm, the
alarms are reset by pressing the UP+DOWN+ OK/MENU keys, via MODBUS or from the
auxiliary digital input.
Totalizer
As an alternative to measuring the frequency of the digital input signal, it
is possible to view the value of the associated totalizer (saved in non-
volatile memory). Both values are available simultaneously in the 11-digit
indicators (4+7).
The totalizer can be:
Increasing: it is increased by one unit at each rising edge of the digital
input.
- Decreasing: it is decreased by one unit at each rising edge of the digital input.
Once the maximum or minimum limit is reached, counting restarts from zero.
It is also possible to set a reduction ratio by which to divide the totalizer
value; the resulting value will then be displayed.
Reset can also take place in the following three ways:
- From auxiliary digital input (if enabled).
- By pressing the three keys simultaneously (if enabled).
- Via Modbus register.
Display of frequency measurement value or totalized value
Three types of operation can be set (except for the 11-digit models that
display both the frequency value and the totalizer
value together) that define the display modes:
- Type 0: both frequency value and totalizer value display. Pressing UP for a few seconds you access the frequency display, pressing DOWN for a few seconds displays the totalized value. When passing to the frequency value for a few seconds the writing appears, passing to the totalized value the writing appears for a few seconds.
- Type 1: frequency measurement display only.
- Type 2: totalizer display only
Average and frequency measurement filtering
The frequency value can be averaged over a settable number of samples. The
average value is then filtered through the 20-level exponential filter and
then shown on the display.
VLF Mode
If the full scale in Hz for measuring the frequency (HI-F) ≤ 1 Hz the
instrument goes to Very Low Frequency Mode (VLF) thanks to which the minimum
detectable frequency value is equal to 0.00015 Hz (1 pulse every 111 minutes).
Password to access the menu
It is possible to enable password protection from the Programming Menu. The
Quick Alarm Menu is always free of passwords.
