4 Function and Device Design
4.1 Function
Application range
The frequency transmitter is used for monitoring the rpm of rotating machines or
system sections in hazardous areas. The connected sensor or contact can be installed
in Zones 0, 1 or Div 1, 2.. The device is permitted for use in Zones 2 and 22 as well as
outside of hazardous areas.
Mode of operation
The frequency transmitter converts intrinsically safe binary input signals into analog
signals proportional to the frequency (non-intrinsically safe). Initiators according to
IEC/EN 60947-5-6 (NAMUR) or potential-free contacts / optocoupler outputs with
suitable resistance wiring can be used as signal transducers. The 9146/10-11-12 variant
additionally provides the function of limit value output or pulse forwarding.
DANGER
Explosion hazard due to modifications and alterations to the device!
Non-compliance results in severe or fatal injuries.
• Do not modify or alter the device.
No liability or warranty for damage resulting from modifications and
alterations.
DANGER
Explosion hazard due to improper use!
Non-compliance results in severe or fatal injuries.
• The device may only be used according to the operating conditions
described in this manual.
• Use the device only for the intended purpose specified in this
manual.

9.2 Parameterizations
9.2.1 DIP Switches "LF" and "ADJ"
The front panel of the frequency transmitter contains a 4-pole DIP switch.
*) Default setting upon delivery, **) see following chapter "Input"
The DIP switches "LF1" and "LF2" are used for activating the line fault detection
(see above table) and for resetting the anti-pumping device
(see chapter "Anti-pumping device"), respectively.
The DIP switches "ADJ1" and "ADJ2" allow the minimum and maximum counts of the
pulse counter for channel 1 and channel 2, respectively, to be reset.
Line faults and auxiliary power failure are signalled via LED, error message
contact at the module and collective error message via pac-Bus
(see chapter "Schematic circuit diagrams of up to 2-channel designs").

Changing the DIP switch settings is also permitted during operation in
Zone 2 and with connected intrinsically safe input signals.
The characteristics of the output signal are set by means of the
"ISpac Wizard" software. It also allows the line fault detection to be
completely deactivated. This setting determines the characteristics of the
device, while the DIP switch is completely ineffective in this case.

9.2.2 Input (via "ISpac Wizard" Software)
The frequency transmitter offers different operating modes, which can be set depending
on the application. The default setting is the operating mode "Frequency via period
measurement".
9.2.3 Signal Processing (via "ISpac Wizard" Software)
The selection allows the frequency range to be restricted for further processing inside
the module. The minimum value of the analog output corresponds to the set minimum
frequency and the same is true of the maximum values.
This allows the user to define the frequency range relevant for him and set it in relation
to the range of the output signal (0 to 20 mA or 4 to 20 mA).
9.2.4 Output (via "ISpac Wizard" Software)
Here the characteristics of the analog and pulse outputs can be configured.
Analog output:
Apart from the selection whether the analog signal should adopt values between
0 to 20 mA or 4 to 20 mA, the characteristics of the output in case of error can be defined.
The selections include "Output error value" (freely selectable), "Keep last value" or
"Fault detection off".
Pulse output:
The pulse output can be activated and deactivated. In addition, a splitter ratio of
between 1 and 20,000 can be entered.
Selection Description
Counter (0 to 65535) Incoming pulses are counted. The analog output signal (0/4 to 20 mA)
is increased linearly until reaching the counter value. The maximum counter
value can be set.
Counter overflow If the overflow is activated, the counter will start counting again when the
maximum counter value is exceeded, and the output signal (sawtooth)
will follow.
When the overflow is off, the counter and the analog signal will stop upon
reaching the maximum value.
They can be reset via the front-panel DIP switches "ADJ1 " and
"ADJ2 "(OFF-ON-OFF and ON-OFF-ON, respectively)
Frequency via period
measurement
For measurements in the range from 1 mHz to 1 kHz.
Frequency via events
(50, 200 or 1000 ms)
For measurements in the range from 1 to 20 kHz.
