In case of sensor error the alarms will react in the same way as range override.

During the softstart the controllers’ output response is limited to a pre-selected ratio, in order
to achieve a slow baking out of high performance heat cartridges.
Simultaneously the output clock frequency is quadrupled. Once the process value reaches
the softstart setpoint, it remains stable at this value for a pre-selcted hold-duration time.
At the end of this period the process value rises to the valid setpoint.
This results in a slower, more regular heating period.
For this purpose the bistable voltage output must be chosen, that actuates SSR relays.
If the softstart is active, the controllers’ autotune function can’t operated (Er.OP).
If a setpoint-ramp has been programmed, the softstart has priority, and the ramp will only
become active after the softstart has been completed.
The softstart only works, if the parameter „1 P“ (prop. band) is programmed > 0,1%.
During the softstart-phase it is not possible to change the setpoint values.
For this, the softstart-phase has to be stopped.

In event of sensor break the controller automatically maintains the
last valid output ratio as the actuating signal.
An „H“ is then displayed as the first digit in the setpoint display,
followed by the valid output ratio. This ratio can be manually altered
in steps of 1% (up/down-keys; enter).
Under the following circumstances, the output ratio will be 0%:
- if the output ratio at time of the sensor break was 100%.
- if the control deviation was more than 0,25% of the total
range at the time of sensor break.
- if the prop.band (P; xp) = 0.
- if the soft start was active at the time of the sensor break.
A few seconds after the sensor break has been rectified, the
controller returns to automatic operation and calculates the required
output ratio.
An additional signal can be issued in the event of sensor break, if
the alarm contacts are programmed accordingly.
Setting: MAn
The controller now operates only as an actuator. Within the
operation level, an output ratio can be entered instead of the
setpoint. An „H“ is then displayed as the first digit in the set-
point display, followed by the output ratio.

The output ratio shows the momentary calculated ratio.
It cannot be altered. The display is in percent of the installed

Only: heating-off-cooling configuration.
A limitation of the output ratio is only necessary when:
- the heating or cooling energy supply is grossly over-
dimensioned compared to the power required, or
- to turn off a control output (setting = 0%).
Under normal circumstances no limitation is needed (setting = 0%).
The limitation becomes effective, when the controllers’ calculated
output ratio is greater than the maximum permissible (limited) ratio.
Warning!
The output ratio limitation does not work during autotune.

OPt self tuning OFF self tuning out of action
(autotune) on self tuning on request ( one time)
Auto self tuning automatically if the controller is switched on
and if the difference between process value and
setpoint is > 7 % of the range.
The tuning algorithm determines the characteristic values within the controlled process, and calculates
the valid feedback parameters ( P,D,I ) and the cycle time ( C = 0.3 x D ) of a PD/I-controller for a
wide section of the range.
The determined parameters for heating are also adopted for cooling.
The self tuning activates during start-up shortly before the setpoint is reached. The setpoint must
amount to the least 5% of the total range.
If activated after the setpoint has already been reached, the temperature will first drop by approx. 5%
of the total range, in order to detect the exact amplification of the process.
The tuning algorithm can be activated at any time by selecting the OPT=on and pressing the „E“-key.
During self tuning „Opt“ is shown in the display, alternating with the setpoint value.
Using the heat-cool controller, the temperature drop will be accelerated by switching on the cooling
for a short duration.
After having calculated the correct feedback parameters, the controller will lead the process value
to the setpoint.

OFSt process value offset -999 ... OFF ...1000 °K (ex works: OFF)
-99,9 ... OFF ... 100,0 °K
This parameter serves to correct the input signal, e.g. for:
- the correction of a gradient between the measuring point and the sensor tip,
- the line resistance balancing of 2-line RTD (Pt100) sensors and
- correction of the control devition when using P- or PD-action.
If for example the offset value is set to +5°C, then the real temperature measured by the
sensor (when process is balanced) is 5°C less than the setpoint and the displayed process value.

If setpoint 1 (SP1) is set to "OFF", the controller switches to stand-by.
The setpoint display then shows "OFF". All main outputs are switched off and the
alarm is de-activated.
All parameters can be displayed and altered during stand-by.
SP2 Setpoint 2 OFF; SP.Lo SP.Hi (ex works: OFF)
The 2. setpoint is active when the external contact K1 is closed.
The corresponding LED „SP2“ lights up on the faceplate,and the second set-point is shown in the
display.“
Please note, that the value of the second setpoint cannot be changed in the oprating level.
In order to change the value the parameter SP2 has to be selected.

Alarm 2 is only available, if the controller is programmed
as a 2-point- or a continuous-controller in the configuration-

Installation Instructions
Make certain that the devices described here are used only for the intended purpose.
They are intended for installation in control panels.
The controller must be installed so that it is protected against impermissible humidity and severe contamination.
In addition, make sure that the permitted ambient temperature is not exceeded.
The electrical connections must be made according to the relevant locally applicable regulations.
If using a thermocouple sensor, the compensation cables must be laid directly to the controller terminals.
Transducers must be connected only in compliance with the programmed range.
Transducer cables and signal lines (e.g. logic or linear voltage outputs) must be laid physically
separated from control lines and mains voltage supply cables (power cables).
To keep the CE-conformity it is nessesary, to use for sensor- and low voltage signal lines shielded cabels.
Spatial separation between controller and inductive loads is recommneded.
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.
IMPORTANT:
Before operation, the unit must be configurated for its intended purpose
(e.g. controller type, sensor type and range, alarm adjustment etc.). Please see „Configuration Level“.

We have checked the contents of the document for 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. The information
given in the publication is, however, reviewed regularly. Necessary amendments are incorporated in the following editions.
We would be pleased to receive any improvement proposals which you may have.
