1. Description
The converter FT 9004 is a frequency divider in a snap-in housing for 35mm rail
mounting. The unit is able to divide input frequencies respectively pulse chains of in-
cremental encoders. The divider value is adjustable by the user. The unit can be used
for input frequencies up to 90 kHz.
There are two operating modes. One mode is able to divide two input pulse chains
90° out of phase applied to the input channels "Input A" and "Input B". A second ope-
rating mode uses only input channel "A" for the input pulse chain. The other input
channel "B" decides when using this mode the direction of the output pulse chains.
There are two open collector output channels "Out 1" and "Out 2". At both operating
modes the output channels "Out 1" and "Out 2" are generating ouput pulse chains 90°
out of phase, divided by the adjusted divider value.
The input channels "Input A" and "Input B" are opto isolated. Source signals of at least
5 mA are needed to drive the input channels. The input voltage level can be set by the
user by internal jumpers to the desired input level of 5 V, 12V or 24 V.
The output channels are isolated from input channels as well as from the power supp-
ly input. The output channels consist of potential free collector-emitter pathes. By that
the customer can create an output level to his own requirements using two resistors
and an external power supply.
The functional structure of the converter is shown in picture 1. There are two adjus-
table resistor networks for input voltage level adjustments, followed by opto coupler
inputs, a frequency divider and the open collector outputs "1" and "2".

2. Safety Instructions
This instrument is produced in accordance with Class II of IEC 348 and VDE 0411.
When delivered the intrument has been tested to meet all functions described. Before
installing the instrument please read the mounting and servicing instructions. We
have no liability or responsibility to customer or any other person or entity with respect
to any liablity, loss or damage caused or alleged to be caused directly or indirectly by
equipment or software sold or furnished by us. Read the installation instruction care-
fully. No liability will be assumed for any damage caused by improper installation.
Inspect the instrument module carton for obvious damage. Be shure there are no
shipping and handling damages on the module before processing. Do not apply po-
wer to the instrument if it has damaged.
ERMA’s warranty does not apply to defects resulting from action of buyer, such as
mishandling, improper interfacing, operation outside of design limits, improper repair
or unauthorized modifications.

4.1. General Instructions
•It is forbidden to plug or unplug terminals with voltage applied.
•Attach input and output wires to terminals only without voltages
applied.
•Cords must be provided with sleeves.
•Attention must be paid that the power supply voltage applied will
agree with the voltage noticed at the name plate.
•The instrument has no power-on switch, so it will be in operation as
soon as the power is connected.
4.2. Hints Against Noisy Environment
All inputs and outputs are protected against noisy environment and high voltage
spikes. Nevertheless the location should be selected to ensure that no capacitive or
inductive interference can have an effect on the instrument or connection lines.
It is advisable:
•To use shielded cables.
•The wiring of shields and groung (0V) should be star-shaped.
•The distance to interference sources should be as far as possible.
If necessary, protective screen or metal enclosures must be pro-
vided.
•Coils of relays must be supplied with filters.
•Parallel wiring of input signals and AC power lines should be avoi-
ded.
•The parallel output lines must be as short as possible.
•It is necessary to use shielded twisted pair cable for the RS422-li-
nes as well as for the SSI signal lines.

5. Function
The converter FT 9004 is a frequency divider in a snap-in housing for 35mm rail
mounting. The unit is designed for dividing pulse chains of incremental encoders by a
predetermined value. The desired divider value is adjustable by the user. The unit
can be used for input frequencies up to 90 kHz. Up-down counting is possible without
loss of pulses.
There are two operating modes available. One mode is able to divide two input pulse
chains 90° out of phase applied to the input channels "Input A" and "Input B". A se-
cond operating mode uses only input channel "Input A" for the input pulse chain. The
other input channel "Input B" decides when using this mode the direction of the output
pulse chains.
There are two open collector output channels "Out 1" and "Out 2". At both operating
modes the output channels "Out 1" and "Out 2" are generating ouput pulse chains 90°
out of phase, divided by the adjusted divider value.
The input channels are isolated. Source signals of at least 5 mA are needed to drive
the input channels. The input voltage level can be set by the user by internal jumpers
to input levels of 5 V, 12V and 24 V.
The output channels are isolated from the input channels and the power supply input.
The output channels are provided as open collector outputs. So the user can crea-
te by resistances output voltages from 3 V to 30 V according to his requirements.
6. Jumper- and DIP-Switch Configurations
For adjustments there are three jumperblocks and two 8-pole DIP switches inside of
the case. To access the jumperblocks and the DIP switches the case has to be ope-
ned. This is simple done with the aid of a small screwdriver. There are two little flat on
each side of the case which must be pressed inwards. The top of the case can now be
separated from the base and the PCB can be pulled out (pic.2).

Input Level Adjustment
On the PCB there are two jumperblocks SL3 and SL4 for input level adjustments
available. Each jumperblock consists of 3 pins. If the jumpers are left open input level
voltage is 24 V. When connecting pin 2 with 3 input level voltage is 12 V and connec-
ting pin 1 and 2 the input level voltage will be 5 V.
Adjustment of the operating mode
The operating mode can be selected by the switch "8" of the 8-pole DIP-switch SW 1.
Position "OFF" of switch "8" requires two input pulse chains with 90° out of phase. If
switch "8" is switched "ON", input channel "A" requires the pulse chain to be divided
and input channel "B" decides the direction of the two output pulse chains.
Adjustment of the divider value
The adjusting of the divider value is done by the two 8-pole-DIP switches SW1 and
SW2. The adjustment range of the divider value is available from 2 to 999. For adju-
sting BCD-code must be applied. The switch assignment of the DIP switches SW1
and SW2 is shown in picture 3.

An input frequency of 24960 Hz has to be divided. The desired output frequency shall
be 195 Hz. The divider value "D" must be calculated:

Important notes about the frequency output:
The output of the FT 9004 consists of a collector-emitter path, which must be exter-
nally wired accordingly.
The external voltage and the resistance must be chosen so that the equipment is
operated within its specifications.
The following should be considered when dimensioning the load resistor:
- The higher should be the output frequency, the smaller the value of the load resistor
must be chosen. When an external voltage of 24 VDC, the value of the load resistor
800 should - be 1000 ohms to still obtain a sufficiently high signal edge at the maxi-
mum output frequency of 25 kHz.
•the maximum allowable current for the collector-emitter path is 50 mA
•should there be problems with the output frequency, it is recommended to control
the output signal with an oscilloscope and adjust the load resistor according to the
specifications.

8. Startup Procedure
Attention must be paid that power supply voltage applied will agree with
the voltage noticed at the name plate.
When delivered, the intrument is adjusted with a standard configuration
(default value of the divider = 1). By changing the adjustment the custo-
mer can alter the standard configuration according to his measuring task.
Attention ! When the instrument is built in a machine and the customer
wants to change the configuration, attention must be paid, that no dama-
ge will occur to the machine!

9. Handling Of Misfunctions
All devices of ERMA-Electronic GmbH are tested for perfect function during produc-
tion as well as when delivered. Nevertheless it is possible that a device won’t work.
That is not allways a reason by the new device. There are many small reasons that
will result in misfunctions. If the FT 9004 won’t work properly, please check the follo-
wing points.
•Look for proper supply voltage
•Look for proper wiring of supply
•Look for proper configuration of the divider value
•Look if high voltage spikes are existing and have an influence to the device.
If all tests are all right, the device must be send back for controling.
