Process- and setpoint value will be displayed simultaneously.
Within the operating level the setpoints and the alarm values can be adjusted
by pressing the " " / " " - keys. Every adjustment has to be quit by pressing the „ E“ - key.
All parameters within the operating level can , in succession, be displayed by pressing the „ P “ - key
and adjusted by pressing the " " / " " - keys.
To switch off the controller function (stand-by operation), the parameter „Cont“ has to be programmed to „OFF“.
After operating the „ P “–key it is possible to preadjust the setpoint „SP1“.
Parameter level:
Enter this level by pressing the „ P “ and „ E “-key appr. 1 sec. simultaneously.
Within the parameter level the values are adjusted to suit the control behaviour to the individual process.
Leave this level by pressing key „ E“ appr. 3 sec..
Configuration level:
Enter this level by pressing the „ P“ and „ E“-key appr. 3 sec. simultaneously.
In the configuration level the controller type, sensor type, the sensor range, the alarm behaviour and the
output type can be pre-selected.
This primary information has to be entered before taking the controller into operation.
The display of each single parameter within the parameter and configuration levels, and their adjustment,
are made in the same way as within the operating level.
After either pressing the „E“ - key for approx. 3 seconds, or waiting for a period of approx. 30 seconds,
the unit will automatically return to the operating level (display of process value and setpoint).

Please note:
In case of sensor error the alarms will react in the same way as range override.
The alarm contacts therefore do not offer protection against all types of plant breakdown.
With this in mind, we recommend the use of a second, independent monitor unit.
If a setpoint ramp has been programmed, the alarms that are relative to the setpoint (signal contact,
limit comparator) follow the setpoint up the ramp.

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: Set parameter „So.St“ to „OFF“

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 softstart function 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

or OUT4 Normally the controller works using PD/I control action.
This means, controlling without deviation and with practically
no overshoot during start-up.
The control action can be altered in its structure by making the
following adjustments to the parameters:
a. no control action, on-off (setting P = OFF)
b. P-action (setting D and I = 0)
c. PD-action (setting I = 0)
d. PI-action (setting D = 0)
e. PD/I modified PID-action

by adjusting the cycle time. This is the total time needed for the
controller to switch on and off once.
OUT 1: Relay outputs: cycle time > 10 secs

The following parameters apply only to the configuration of heating-off-cooling controllers
and are valid for cooling control action:
Sh switch-point OFF; 0,1...80,0 °K (ex works: OFF)
difference OFF; 0,01...8,00 °K
This parameter raises the setpoint (switch-point) for cooling output
by the displayed value. It can be help to reduce the switching
frequency between the heating and cooling outputs, if this is to
high.
Simultaneously activation of heat and cool outputs is not possible.

OPt selftuning 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 selftuning 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.
It is not possible to start the selftuning mode, if the softstart function or the manual mode is activated.
Display: error warning „Er.OP“. Press Key „E“ to quit the error warning.
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 parameter „Cont“ is programmed „on“, the setpoint can be
adjusted directly in the operating level and is activ, if the external
contact K1 is opened.
If parameter „Cont“ is programmed „OFF“, the parameter SP1 has
to be selected (press key „P“). Than the setpoint can be preadjusted.
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.
SP rising ramp OFF; 0,1...100,0 °C/min. or °F/min. (ex works: OFF)
SP falling ramp OFF; 0,1...100,0 °C/min. or °F/min. (ex works: OFF)
A programmed ramp is always activated when the setpoint is altered or when the mains supply is
switched on. The ramp constructs itself out of the momentary process value and the pre-selected
setpoint. If the ramp is active, the corresponding LED lights up on the faceplate. The ramp can be
activated for both setpoint1 and setpoint2. By programming the second setpoint accordingly a
setpoint profile can be oblained (please see example below).
