7 Parameter descriptions:
7.1 Configuration Parameters, Valid for the Complete evice
Alarm configurations, general information:
Each alarm contact works as a common alarm for all zones. The individ al alarms A1 (A2) of all zones
are connected to the common contact A1 (A2). The selected config ration is valid for all active zones.
Please note:
Care sho ld be taken to ens re that the setpoints of the alarm contacts are programmed within the
selected meas ring range. If a setpoint ramp has been programmed, the alarms that are relative to
the setpoint (signal contact, limit comparator) follow the setpoint ramp.
In case of sensor error the alarms react in the same way as range override.
The alarm contacts therefore do not offer protection against all types of plant breakdown.
We recommend the se of a second, independent monitoring nit.

Heater current monitoring (option)
The heater c rrent monitoring f nction is valid for all connected zones.
The following parameters are displayed when the alarm config ration is programmed to “heater
c rrent” (8 or 9).
The alarm val e (heater c rrent val e) is programmed as an absol te val e.
Please note: Ens re that the limit val e is set correctly to avoid false alarms in case s pply voltage
changes. The alarm can be delayed by selecting a delay time “dL.Ax”.
The monitoring f nction and all parameters are valid for all connected zones.

Monitoring concerning an impermissible permanent c rrent
SSRs (especially if they are combined with RC-combinations) normally
have small leakage c rrents.
A leakage c rrent limit val e is programmable. All val es below this limit
will not be considered in the alarm monitoring.
If a permanent c rrent is detected in one zone the alarm relay will be
activated and the display „PROCESS“ will show the error signalisation
„Er.C “.
The zone with a meas red permanent c rrent can be located by pressing
the zone key and watching all temperat re indications.
Display indication in this case: „Comparable with„temperat re too high.“

Serial Interface (RS232, RS485 or TTY)
The controllers of the series R2400 can be eq ipped with a serial interface RS232, RS485 or
0/20mA (half-d plex) as an option.
This enables a master (PLC) to set and to read the process- and config ration parameters.
The comm nication is always controlled by the master. The controller operates as a slave.
If there are transmission or range errors detected by the slave, the message is not accepted and the
existing parameter val es remain valid.
It is not possible to operate the device by keyboard if it is set to remote-operation by the master.

Softstart Function in General:
If yo select the softstart f nction, make s re that the instr ment is eq ipped with bistable voltage
(logic) o tp ts. This f nction is not allowed for instr ments with relay o tp ts. Otherwise the relays
will be damaged.
D ring the softstart the controller's heating o tp t response is limited to a preselected ratio,
in order to achieve a slow drying of high performance heat cartridges.
This res lts in a slower, more reg lar heating period.
Sim ltaneo sly the o tp t clock freq ency is q adr pled.
Once the process val e reaches the softstart setpoint, it remains stable at this val e for the
preselected d ration time.
At the end of this period the process val e rises to the valid setpoint.
If the softstart is active, the controller's a tot ne f nction 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 act al process val e is lower than the softstart setpoint
– 5% of the selected meas ring range
It is possible to select this f nction for each zone individ ally.

- if the Proportional-band (P) = off.
- if the softstart was active at the time of the
sensor break.
A few seconds after the sensor break has been
rectified, the controller ret rns to a tomatic
operation and calc lates the req ired o tp t
ratio.
An additional signal can be iss ed in the event
of sensor break, if the alarm contacts are
programmed accordingly.
Man al Mode
The controller now operates only as an
act ator. The control f nction (PID) is inactive.
PROCESS: Act al process val e is shown.
Display of setpoint: First an “H“, then the
act al adj stable o tp t ratio.
Negative val e: cooling, positive val e: heating
Like the setpoint, the o tp t ratio can be
changed man ally.

7.3 Control Parameters, Zone ependent
valid o tp t ratio
0 … 100%
The o tp t ratio shows the momentary calc lated ratio.
It cannot be altered. The display is in percent of the installed
performance capability for heating or cooling.
O tp t ratio for cooling is shown as a negative val e.
O tp t ratio limit
„heating“
0 … 100%<§ >
The limitation of the o tp t ratio is only necessary if the heating
energy s pply is grossly overdimensioned compared to the power
req ired.
Under normal conditions a limitation is not necessary (setting =
100%).
The limitation becomes effective when the controller's calc lated
o tp t ratio is greater than the maxim m permissible (limited)
ratio.
Warning!
The o tp t ratio limitation does not work d ring a tot ne.

Adjustment of the control parameters:
As standard the controller operates in PD/I control mode, i. e. controlling witho t deviation and with
practically no overshoot d ring start- p.
3-point controllers (marked with: >3<) have a second ”cooling“ parameter set.
The control action can be altered in its str ct re by adj sting the following val es to the parameters:
a. no control action, on-off
b. P-action
c. PD-action
d. PI-
e. PD/I

The cycle time sho ld be adj sted to a time as long as possible
to minimize the wear of the relay contacts.
