Please observe the notes in these operating instructions together with the
conditions of use and permitted data that are specified in the data sheets of
the 0911 controller, so that the device will function perfectly and will have a
long service life.
• Keep to the standard engineering rules when planning and operating the
device!
• Installation and maintenance work may only be carried out by specialist
personnel using the correct tools!
• Observe the current regulations on accident prevention and the safety
regulations for electrical devices during the operation and maintenance of
the device!
• Comply with the intended usage of the device.
• Only operate the device with its housing fitted.
• Before connecting the device, check that the power supply corresponds to
the values printed on the device.

MEASUREMENT LIMITS FOR THE SENSOR TYPES
2.4 SOFT-Start function
dSI = Increase the set-value in steps (in °C or °F; deactivated with 0).
dSt = Cycle time for the step-by-step increase of the set-value
(1...3600 sec).
drb = Increasing the set-value (in °C or °F); the function is deactivated with
drb = 0. This value determines the set-value increase in steps in Kelvin
or °F.
drb Soft-Start range (in °C or °F; deactivated with 0). If the temperature
is outside this range (on both sides of the set-value),
a new SOFT-Start will be initiated.
dSI Dynamic set-value increase (in °C or °F; deactivated with 0). This
value determines the step-by-step increase of the set-value of SET1.
dSt Clock time for the dynamic set-value increase (1...999 sec) or dSl
(SOFT-Start).
Ta = Measured temperature after device commissioning.
t = Time axis.

0911 - 9
english
Starting from the measured temperature Ta, the set-value is increased in steps
by dSl, but the SOFT-Start will only begin when Ta is outside the drb range:
Dynamic set-value = Ta + dSI
The clock time indicates with dSt when the dynamic set-value is increased by
dSl.
The dynamic set-value is set to Set-value 1 if the amount dynamic
set-value - Set-value < drb:
If | current dynamic set-value - set-value 1 | > drb,
automatic default: Dynamic set-value = Set-value 1
The SOFT-Start is ended.
If the measured temperature of the belt exceeds or falls below drb, the SOFT-
Start starts again.
2.5 Proportional control
In the case of unsatisfactory controller results with factory parameters, we
recommend that you proceed as follows:
1. Enter the switch hysterisis mode for Output 1 (Ft = 0)
2. Set Set-value 1 to a value that will not endanger the installation though
excessive vibration, e.g., 10% below working temperature.
3. Set the switch hysterisis setting Par. Hy1) to 3 % of the working
temperature (Set-value 1).
4. Start the system and wait until the vibration remains constant.
5. Evaluate (poss. using a plotter) the values Tp and dT
(see diagram)
6. Calculate the parameters Pb, Int, dEt, Cyt from these values -
as follows:
Pb = 2 x dT
Int = Tp / 2
dEt = Tp / 8
Cyt = Tp / 20

2.6 Parameters
Explanation of the PID components:
• The proportional components act on changes within the band around
the set-value.
• The differential components influence the speed of temperature
changes.
• The integral components adds together all surfaces (time x tempe-
rature), that arise from the deviation of the actual value from the set-
value. The greater the deviation, the higher the effect.
NOTE • An increase of the proportional range results in a larger
remaining control deviation between the set-value and the
actual value.
• A significant reduction of the proportional range reduces
the control deviation, although the control behaviour will
become less stable.
• The derivative action time (differential time) affects the
output dependent on the speed of the temperature change.
An increase of the drivative action time reduces the
vibration tendency after system stabilisation, but can
generate higher vibration with larger deviations, however.
• An reduction of the integral range increases the effect
on the deviation between the set-value and the actual
value.
Control

positive or negative values. The default
range is dependent on the input type.
