General:
KFM 903 is an industrial microcomputer-based controller series in control panel format 96 x 96 mm
with a performance range of up to 9 relay outputs (changeover), various signal inputs and outputs
as well as numerous possible optional extras. Communication with control systems is also possible.
Additional contacts can be switched time dependent using the integrated real time clock.
Controllers of the series 903 can be delivered with the type extension K in a freely programmable
version and then available functional packages can be added arbitrary within the hardware, using a
graphical workspace, so that a separate control system is often not necessary.
The belonging module software 99pkm provides beside ready to use controller modules a large
number of control functions and logical operations compact within the individual device, furthermore
expansion modules, an external malfunction alarm unit or a second freely programmable
controller 903K can be added to it by using the standard interface.
Alternatively, the delivery can be done unprogrammed with hardware in various types. In this case
the programming is provided by the customer or at extra cost by the factory.
The transmissive colour TFT indication is easy to read in both light and dark environments.
Parameter set, TFT- configuration, data logger recordings and fault history can be transferred by
means of conventional USB stick. Irrespective from that, the continuous logger data is automatically
saved on a regular basis if the USB stick is inserted.
The touch operation of the TFT- display is optionally available.
Depending on version, the industrial controller can configured and read out via USB stick.

Electrical wiring
•Plug bar on the back face of the controller; connect up the controller following the wiring
diagram on the device.
•Only the terminal blocks supplied are to be used. Replace existing old terminal blocks.
•For connecting power supply phase wire and neutral wire must not be transposed.
•Wire cross section max. 1,5 mm2
•Lay input-, output and supply cabling physically seperated and not parallel to one another.
•Use shielded and twisted cables for the measuring-, control- and interface circuits to avoid
interferences; Ground the shield properly. Do not lay close to components or cables through
which current is flowing.
•Do not loop through ground wires, but connect to a common grounding point in the control
cabinet; furthermore, a professional potential equalization must be noted and the lines must
be kept as short as possible.
•The DIN VDE 0100 “construction of low-voltage systems” respectively the appropriate
country specific regulations (for example on basis of IEC 60364) must be followed for the
wiring material, the installation and the electrical wiring.
•Depending on version and application, possibly mount the enclosed RC-elements (external)
or the jumper (internal RC-elements) in accordance to the wiring diagram.
See chapter RC-elements on page 19
Putting into operation
Switch on power supply. Digital display and control lamps (if available) will light up according to the
setpoint after some seconds. Adjust set value and check other adjustments.
Maintenance
All electronic controllers in the product range of the manufacturer are virtually maintenance-free.
Provided that the controller is correctly installed and put into operation and is protected against
mechanical damage and inadmissible operating conditions, it should give years of trouble-free
service. In case of faults repair work by the customer should be restricted to the externally
accessible leads, connections and components the customer is expressly permitted to deal with
himself (bridge circuits, fuses).
All further work, especially on internal components will terminate warranty, makes subsequent
inspection and fault repair more difficult and can cause considerable damage to the circuitry.
For repair remittance remove plug board with connected leads on the rear side,
loosen fastening devices and remove controller from the panel.
In case of remittance please give precise details of the fault to reduce time and cost of repair.

manual optimization
An optimum adaptation of the control Optimal
parameters (P,I,D) is necessary in order to
balance an appearing deviation as quickly, non-
oscillating and exactly as possible, according to
the given operating conditions.
Generally these adjustments require a lot of
professional knowledge that cannot be replaced
by this brief information. The following
informations are for help purpose only:
P = proportional band Xp (%):
lower value = longer impulses (three-point step control), more sensitive reaction,
higher value = shorter impulses (three-point step control), less sensitive reaction.
Examples:
-Oscillating temperature
without distinct initial overshot:
P(Xp) too low;
- The setpoint is reached very slowly
after initial overshooting:
P (Xp) too high.
I = integral action time Tn (min):
lower value= shorter impulse gaps (three-point step control), faster balancing,
higher value= longer impulse gaps (three-point step control), slower balancing.
Examples:
-the set value is reached very slowly
without overshooting:
I (Tn) too high;
-high initial overshot followed by fading
oscillation:
I (Tn) too low.
D = rate time Tv (min):
increases the controller reaction in case of fast actual value or setpoint alterations
(adjust only if necessary). Higher values cause higher increase.

Self-adaptation (optional)
The self-adaptation is an automatic procedure that determines and self-adjusts
the optimum control parameters Xp, Tn and Tv.
Operation, if contained in supply schedule:
(Parameter-safety-switch on the rear panel of the controller (if available) has to be unlocked:
position "u")
Check starting assumptions:
Actual value at least 20% below the adjusted set value,(e.g.:heating phase), otherwise first:
Lower actual value adequately by manual operation (position of final control element) (quick
circuits)or increase setpoint adequately, if admissible. (faster procedure for slower circuits)
Call manual operation level: Press - key plus - key (optional: seperate key).
Check controller output: must not be higher than 85% , reduce if necessary.
Start self-adaptation: Hold down - key for more than 5 sec. on manual operation level.
During operation the lower display shows: "-Ad-",
the upper display still shows permanently the actual value.
Information about operation: First the self-adaptation program waits for stabilization of the
actual value according to the given controller output (actual value alteration < 0,1% /
min),then it increases the output signal about 10% or, in case of three- point- step controller
operation,it triggers an output impulse with about 10% of the adjusted regulating time.The
optimum parameters are computed according to the unit- step response.
Cancel: Press - key for more than 5 sec. = return to manual operation level
After successfully finishing the procedure the controller will return automatically
to operating level.
Unsuccessful adaptation
(Display shows error code, ref.to chapter error messages on page 17)
Press - key again: Return to manual operation level
eliminate the indicated error
start adaptation again: - key > 5 sec.
or return to operating level: - key shortly

LC E Make contact on either side of setpoint
(Limit comparator). Relay picks up as
deviation increases (Ein = on)
Su A Break contact below setpoint. Relay drops out
as actual value decreases (Aus = off)
Su E Make contact below setpoint. Relay picks
up as actual value decreases (Ein = on)
So A Break contact above setpoint. Relay drops
out as actual value increases (Aus = off)
So E Make contact above setpoint. Relay picks
up as actual value increases (Ein = on)
St A Heating stage below setpoint. Relay
