2 Installation 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 controller 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-combinations parallel to the coils.
Control circuits (e.g. for contactors) should not be connected to the mains power supply terminals of the controller.
The configuration parameters (Window: System) are generally to be selected first.

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 externally:
+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.

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 program step again, in which the interruption happened.

The autotune mode works during start-up shortly before the setpoint is reached. If activated after the setpoint has already been reached, the temperature will first drop by approx. 5% of the measuring range.
The tuning algorithm can be activated at any time by selecting the parameter
Autotune = ”on”. After having calculated the feedback parameters, the controller will lead
the process value to the actual setpoint.
Selecting Autotune = ”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.

Ramps: Ramp rising / Ramp falling
A programmed ramp is always
activated when the setpoint is
changed or when the mains
supply is switched on. The
ramp starts at the actual process value and ends at the preselected setpoint. The ramp
can be activated for both setpoint 1 and setpoint 2. By programming the second setpoint
a setpoint profile can be obtained, accordingly (see example with external contact In_1
(K1) below).

Menu: Softstart
Softstart-Function
For using the
softstart function, make sure that the instrument is
programmed to
voltage
(logic) outputs. This function is not allowed for relay outputs. Otherwise the relays will be
damaged. During the softstart the controller's heating output response is limited to a preselected ratio, in order to achieve a slow drying of high performance heat cartridges. This
results in a slower, more regular heating period.
Simultaneously the output clock frequency is quadrupled.
Once the process value reaches the softstart setpoint, it remains stable at this value for
the preselected duration time. At the end of this period the process value rises to the valid
setpoint. If the softstart is active, the controller's autotune function cannot operate.
If a setpoint ramp has been programmed, the softstart has priority, and the ramp will become active after the softstart has been completed.
The softstart only works:
- if the parameter P (xp) is programmed > 0,1%
- if the actual process value is lower than the softstart setpoint – 5% of the selected
measuring range
It is possible to select this function for each zone individually.

Independent of this the -alarms can be connected to the zone relays or logic outputs.
If a setpoint ramp has been programmed, the -alarms that are based on the setpoint fol-
low the setpoint ramp.

Configuration Current alarm (option)
The heater current monitoring function is valid for all connected zones.
Only zones with logic output for the heating signal will take part in current monitoring.
Ensure that the limit value is set correctly to avoid false alarms in case of supply voltage
changes. The alarm can be delayed by selecting a delay time to avoid false alarms caused
by single disturbances.
The heater current measuring is designed for a current transformer 1:1000.
(Accessory type: M2000 1:1000 max. 60A)
When using other transformers the ratio can be modified.

A leakage current limit value is programmable. All values below this

The field “act. Leakage current” displays the leakage current that has
just been measured.
If a permanent current (SSR short circuit) is detected the alarm will
be activated.
The zone with a permanent current can be detected by observing

Cycle time for writing an output line
with time stamp
on the
USB stick. The values setpoint, actual value, output ratio and
current actual value of all zones are written out.
If the parameter "Log interval" is set to a numerical value, so a file named
“LogR4000_xxxxx_YYYY_MM_DD.txt” is generated on the USB stick. “xxxxx” the last 5 digits of the MAC-ID. YYYY, MM and DD mean the year, month, day. After a change of date a
new file is created.
With the included names MAC-ID “xxxxx”, the files can be assigned to different R4000 controllers.
Each "Log interval" time a new row is added. The line includes a time-stamp, setpoint, the
actual value, the output ratio and the actual current value of Zone 1 to Zone 4/8.

Firmware update
Start the firmware update by selecting the button "Start Update" and
confirm with SAVE. A confirmation prompt opens. If this window is confirmed with YES, the unit turns into the loader mode.
When the loader mode is accidentally turned on, you can switch back by
a mains reset into the existing user program.
If an update should be performed, a USB flash drive must be plugged in
with the new firmware. After a short time the firmware folder appears in
the line "Folder". E.g. „EL4000.01_V20xx_xx.ELO“.
Now you can start the loading process by touching the touch screen.
The controller must not be disconnected from the power supply until the
download is complete!
After finished loading the new user program is started by a power interruption.
