2Installation Instructions
Make sure the device is used for the intended purpose only.
R4000 controllers are designed for installation in control panels.
Protect the device against impermissible humidity and contamination.
The permitted ambient temperature range may not be exceeded.
Electrical connections must be made according to valid regulations and by properly qualified
personnel.
If using thermocouple sensors, compensation lines have to be connected directly to the con-
troller terminals. Sensors may be connected only in compliance with the programmed range.
Sensor cables and signal lines (e.g. logic or linear voltage outputs) must be laid separately
from control lines and mains voltage supply cables (power cables).
In order to maintain CE-Compliance screened detectors - and signal lines have to be used.
It is not permitted to connect the grounds of the sensor-inputs and logic-outputs with each
other.
Separate installation of controller and inductive loads is recommended.
Interference from contactor coils must be suppressed by connecting adapted RC-combina-
tions parallel to the coils.
Control circuits (e.g. for contactors) should not be connected to the mains power supply ter-
minals of the controller.
The configuration parameters (Window: System) are generally to be selected first.
Disclaimer of Liability
The contents of this document is checked for the conformity with the hardware and software
described. Nevertheless, we are unable to preclude the possibility of deviations so that we
are unable to assume warranty for full compliance. However, the information given in the
publication is reviewed regularly. Necessary amendments are incorporated in the following
editions.
We would be pleased to receive any improvement proposals which you may have.
The information contained herein is subject to change without notice.
Electronic scrap and components are subject to special treatment and must be disposed of
by authorised companies.

It is not permitted to connect the grounds of the sensor-inputs and logic-outputs with each
other!
RTD: The parameter “Sensor Settings Sensor” has to be set accordingly to the connection
diagram (2-wire 3-wire)
4.4 Connection Diagram: Logic Outputs
The power supply for the logic outputs has to be wired ex-
ternally:
+24V have to be applied to the terminals B3 and G3.
B3 is connected internally to E3 and G3 is connected to K3.
So the terminals E3 and K3 can be used to loop the +24V.

5Display and Keyboard
The device is equipped with a backlight color LC-display.
After switching on the controller and completion of the initialization, the actual process val-
ues and setpoints of all connected zones are displayed.
The device is operated by menus. The different parameters are displayed mainly in plain text
and can be displayed in various languages.
There are several windows for different functions and settings.

Course of program control:
Preliminary the time and temperature values for the desired steps have to be entered in the
window "program steps setting".
The time for the first step is the dwell time on the associated setpoint.
The time for the subsequent steps describes the duration, the program needs to reach from
the setpoint value of the previous step to the setpoint value of the current step.
For example.
Step 1: 0:20 h 80 ° C -> Initially set the setpoint of 80 ° C for 20min.
Step 2: 0:30 h 360 ° C -> After that the setpoint is continuously increased starting
at 80 ° C, so that after 30 minutes 360 ° C has been reached.
Step 3: 0:20 360 ° C -> Holding setpoint 360 ° C for 20 min.
Step 4: 00:40 55 ° C -
> Reducing the setpoint continuously within 40 minutes from

C.
Step 5: OFF 0 ° C -> This step is not executed.
The last step is the step before the step with time is set to OFF. If no time of the program is
turned "OFF", this is the Step 8.
After the total time of a started program the last setpoint is maintained.
After a power failure, during the program was running, the controller switches to the pro-
gram step again, in which the interruption happened.
5.4.6 Window: Parameter
This window is used as a display and input of all zone-parameters for all zones.
The header displays on the left the

The tuning algorithm determines the characteristic values within the controlled process
and calculates the valid feedback parameters (P, D, I) and the cycle time. (= 0.3 x D) of a
PD I- controller for a wide section of the range.
The autotune mode works during start-up shortly before the setpoint is reached. If acti-
vated after the setpoint has already been reached, the temperature will first drop by ap-
prox. 5% of the measuring range.
The tuning algorithm can be activated at any time by selecting the parameter
utotune = ”on”. After having calculated the feedback parameters, the controller will lead
the process value to the actual setpoint.
Selecting utotune = ”off” will stop the autotune function.
Autotune active: Indication in display “Zone synopsis“ and “Actual process values” as an
orange symbol:
Autotune duration > 2 hours: autotune stops with an error message.
Conditions for starting the autotune algorithm:
- The setpoint must amount to at least 5% of the measurement range
- The sensor must not have a failure.
- The softstart function must not be active

Hints for adjusting the control parameters:
As standard the controller operates in PD I control mode, i.e. controlling without deviation
and with practically no overshoot during start-up.
The control action can be altered in its structure by adjusting the following parameters:
