Frequency Converter, 3 Way 931S-F1C2D-DC

10000043403

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 housing 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

SW2

SW1

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!
