2 General Information
Messages shown by the controller display
<§> Symbolizes the val e of the factory adj stment of the respective
parameters.
>3< This parameter is available in 3-point controllers only.
3 Installation Instructions
Make certain that the device is sed for the intended p rpose only.
R2400 controllers are designed for installation in control panels.
Protect the device against impermissible h midity and contamination.
Ambient temperat re may not exceed 50 °C (122 °F).
Electrical connections m st be made according to valid reg lations and by properly q alified
personnel.
If sing thermoco ple 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 o tp ts) m st be laid separately from
control lines and mains voltage s pply cables (power cables).
It is not permitted to connect the gro nds of the sensor-inp ts and Logic-o tp ts with each other.
Separate installation of controller and ind ctive loads is recommended.
Interference from contactor coils m st be s ppressed by connecting adapted RC-combinations parallel
to the coils.
Control circ its (e.g. for contactors) sho ld not be connected to the mains power s pply terminals of
the controller.
The config ration parameters are generally to be selected first.

Key functions:
Zone preselection
Parameter key (parameter preselection)
Adj stment of chosen parameter (e.g. setpoint) to higher or lower val es.
Short operation: single-step adj stment
Longer operation: q ick-scanning
When the parameter adj stments have been altered b t not entered,
the display will flash bright/dark.
Confirmation and storage of the preselected val es.
The display will show a light chain as a control of this f nction.
Sets the parameter back to the originally stored val e.
Any alterations made to the parameters, that are not confirmed (E-key) within
30 seconds, will not be accepted and the parameter will ret rn to its originally
stored val e. The act al process val e and the setpoint val e will be indicated.
F nction key, E. g. all zones are displayed cyclic (zone scanning on/off).
Zones, which are not in action (OFF), are not displayed.
The f nction of this key can be programmed into the config ration level of zone 0.
See parameter „Co.F1“.

Tendency isplay
After switching the instr ment „on“ a temperat re tendency display will be shown, to give an overview
abo t the temperat res deviations relating to the setpoints in the individ al controller zones.
Zone:
1 2 3 4
Display examples:
Zone 1: Controller o tp t active
temperat re OK
(Bar central)
Zone 2: Controller o tp t not active
Process val e is higher than setpoint
>0,5 % of meas ring range (Bar top)
Zone 3: Controller o tp t not active
temperat re OK
(Bar central)
Zone 4: Controller o tp t active
Process val e is lower than setpoint
<0,5 % of meas ring range (Bar bottom)
Zone:
1 2 3 4
Zone 1: Top range end has been reached (sensor
break)
Zone 2: Bottom range end has been reached
(sensor error, open)
Zone 3: Selft ning algorithm is active
Zone 4: Man al mode
The displayed decimal points show the act al sit ation of the controller o tp t.
Flashing digit: Alarm indication in the matching zone

6.2
Operating Levels
The operation of the controller is divided into 3 levels.
After power p of the device, it will be a tomatically in the operating level.
Operating level (valid for each zone separately):
Process- and Setpoint val e will be displayed sim ltaneo sly. Within the operating level the setpoint
can be adj sted by pressing the„UP" / „ OWN" - keys.
Every adj stment has to be confirmed by pressing the „ E “ - key.
All parameters within the operating level ( incl ding the alarm val es ) can , in s ccession, be
displayed by pressing the „ P “ - key and adj sted by pressing the „UP" / „ OWN" - keys.
Confirm by pressing the „ E “ - key.
Parameter level: (valid for each zone separately)
Within the parameter level the val es are adj sted to s it each individ al process.
This level is reached by sim ltaneo sly pressing the „ P" - and „ E " -keys.
The display of each single parameter within the parameter level and their adj stment are made in
the same fashion as within the operating level.
After either pressing the „ E “ - key for approx. 1 second, or waiting for a period of approx. 30
seconds, the nit will a tomatically ret rn to the operating level
Configuration level: (valid for the complete device)
Select zone “0”. Then press sim ltaneo sly the „ P " - and "„ E " - keys for a period of approx. 5
seconds.
This general settings have to be made first.
Configuration level: (valid for each zone separately)
Select zone 1...4. Then press sim ltaneo sly the „ P " - and "„ E " - keys for a period of approx. 5
seconds.
There is a copy f nction available. So it is possible to copy the programmed parameters of one zone
to other zones.
