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:

1. Alarm on the minimum threshold.
2. Alarm on the maximum threshold.
3. Alarm on the minimum held threshold (does not automatically reset).
4. Alarm on the maximum held threshold (does not automatically reset).
5. 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:

1. 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.
2. Type 1: frequency measurement display only.
3. 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.
