1. General instructions
• Disconnect power prior to installation
• Installation only by Qualified personnel
• Follow all applicable local and national electrical codes
For applications with high isolation voltages, take measures to prevent
accidental contact and make sure that there is sufficient distance or
insulation between adjacent devices!
Appropriate safety measures against electrostatic discharge
(ESD) should be taken during assembly and adjustment work on
the 931S-F1C2D-DC.
2. Application
The 3 Way Frequency Converters 931S-F1C2D-DC are used for galvanic
isolation and conversion of frequency signals. Input and output signals
can be calibrated/switched via DIP switches. It is not necessary to adjust
the pre-settable measurement ranges. The output signal is linear to the
frequency.

3. Configuration
3.1 Equipment
A screwdriver with a width of 2.5 mm is required to adjust the unit and to
connect the wires to the terminals.
3.2 Opening the unit
Disconnect the plugs. Disengage the top part of
the housing by carefully pressing the latches on
both sides (1). Pull out the top part of the hou-
sing and the electronics section until they lock
(2).
3.3 Settings
Set input and output ranges, minimum input values
and measuring span via the DIP switches SW1 and
SW2.
Set the input range via the DIP switches
(no frequency generator required):
2 cases are to be distinguished:
1. below measurement frequency = 0 Hz
– Select operating mode "0...fmax". S2.3 = 0 and S2.4 = 0
– Set upper measurement frequency via the DIP switches
S1 and S2.1, S2.2 (see table).
– Ready!
2. Lower measurement frequency ≠ 0 Hz
– First, the lower measurement frequency has to be saved.
Select operating mode "save from fmin". S2.3 = 1 and S2.4 = 0

Set upper measurement frequency via the DIP switches S1 and S2.1, S2.2
(see table).
Connect the module to the power supply to save the frequency.
– Select operating mode "fmin...fmax". S2.3 = 0 and S2.4 = 1
– Set upper measurement frequency via the DIP switches S1
and S2.1, S2.2 (see table).
– Ready!
Setting the input range using a frequency generator:
– Select the switch setting for saving the min. frequency
S2.1=0; S2.2=1; S2.3=1 and S2.4=1
– Apply min. frequency to the module
– Connect the module to the power supply.
– The LED lights up when the input frequency is measured.
The frequency has been saved when the LED goes out;
the module can be disconnected from the power supply.
– Repeat the process with the max. frequency: S2.1=1;
S2.2=0; S2.3=1 and S2.4=1.
– Select special range: S2.1=1; S2.2=1; S2.3=1 and S2.4=1
– Ready!

1. Allgemeine Hinweise
Die Analogsignaltrenner der Reihe 931S-F1C2D-DC dürfen nur von
qualifiziertem Fachpersonal installiert werden. Erst nach der fachgerechten
Installation darf das Gerät mit Hilfsenergie versorgt werden. Während des
Betriebs darf keine Bereichsumschaltung vorgenommen werden, da hierbei
berührungsgefährliche Teile offen liegen. Die nationalen Vorschriften (z. B.
für Deutschland DIN VDE 0100) bei der Installation und Auswahl der Zulei-
tungen müssen beachtet werden.
Bei Anwendungen mit hohen Isolationsspannungen ist auf genügend
Abstand bzw. Isolation zu Nebengeräten und auf Berührungsschutz zu
achten!
Bei Montage und Einstellarbeiten am 931S-F1C2D-DC ist auf
Schutzmaßnahmen gegen elektrostatische Entladung (ESD) zu
achten.
2. Anwendung
Der Analogsignaltrenner 931S-F1C2D-DC dient zur galvanischen
Trennung und Umwandlung von Frequenzsignalen. Ein- und Aus-
gangssignal sind über DIP-Schalter kalibriert umschaltbar. Ein Nach-
justieren der voreinstellbaren Messbereiche ist nicht erforderlich.
Das Ausgangssignal ist linear zur Frequenz.

3. Konfigurierung des Gerätes
3.1 Hilfsmittel
Zum Einstellen des Gerätes und zum Anschluss der Leitungen an die
Klemmen wird ein Schraubendreher mit einer Klingenbreite von 2,5 mm
benötigt.
3.2 Gerät öffnen
Stecker abziehen. Durch leichten Druck den
Verschluss auf beiden Seiten des Gehäuses
entriegeln (1), Gehäuseoberteil und Elektronik
herausziehen (2).
3.3 Einstellungen
Einstellung von Ein- und Ausgangsbereich,
minimalen Eingangsgröße und Messspanne mittels
der DIP-Schalter SW1 und SW2.
Einstellen des Eingangsbereiches über die DIP-
Schalter (kein Frequenzgenerator erforderlich):
Es sind 2 Fälle zu unterscheiden:
1. untere Messfrequenz = 0 Hz
– Betriebsart "0...fmax" auswählen. S2.3 = 0 und S2.4 = 0
– obere Messfrequenz über die DIP-Schalter S1 und S2.1, S2.2
einstellen (siehe Tabelle)
– Fertig
2. untere Messfrequenz ≠ 0 Hz
– zunächst muss die untere Messfrequenz gespeichert werden.
Betriebsart "speichern von fmin" auswählen. S2.3 = 1 und S2.4 = 0

Frequenz über die DIP-Schalter S1 und S2.1, S2.2 einstellen (siehe Tabelle)
Zum Speichern der Frequenz den Baustein kurz an die Spannungsversor-
gung anschließen
– Betriebsart "fmin...fmax" auswählen. S2.3 = 0 und S2.4 = 1
– obere Messfrequenz über die DIP-Schalter S1 und S2.1, S2.2
einstellen (siehe Tabelle)
– Fertig
Einstellen des Eingangsbereiches mit einem Frequenzgenerator:
– Die Schalterstellung für die Speicherung der min. Frequenz wählen:
S2.1=0; S2.2=1; S2.3=1 und S2.4=1
– Min. Frequenz am Baustein anlegen
– Baustein an die Spannungsvorsorgung anschließen
– Die LED leuchtet auf, wenn die Eingangsfrequenz gemessen wird.
Wenn die LED erlischt ist die Frequenz gespeichert worden und der
Baustein kann wieder von der Spannungsversorgung getrennt werden.
– Vorgang mit der max. Frequenz wiederholen: S2.1=1; S2.2=0; S2.3=1
und S2.4=1
– Sonderbereich auswählen: S2.1=1; S2.2=1; S2.3=1 und S2.4=1
– Fertig
