)All necessary settings are described in these operating instructions. However, if any difficul-
ties should still arise during start-up, you are asked not to carry out any unauthorized ma-
nipulations on the unit. You could endanger you rights under the instrument warranty!
Please contact the nearest subsidiary or the main factory in such a case.
EWhen returning chassis, assemblies or components, the regulations of EN 100 015 “Protec-
tion of electrostatically sensitive components” must be observed. Use only the appropriate
ESD packaging for transport.
Please note that we cannot accept any liability for damage caused by ESD (electrostatic dis-
charge).

Installation notes
- The choice of cable, the installation, the fusing and the electrical connection must conform to
the requirements of VDE 0100 “Regulations on the Installation of Power Circuits with nominal
voltages below 1000V”, or the appropriate local regulations.
- The electrical connection must only be carried out by qualified personnel.
- If contact with live parts is possible when working on the instrument, it must be isolated on
both poles from the supply.
- A current limiting resistor interrupts the supply circuit in the event of a short-circuit. The load
circuit must be fused for the maximum relay current in order to prevent welding of the output
relay contacts in the event of an external short-circuit.
- Electromagnetic compatibility conforms to the standards and regulations listed under
Technical Data.
- Run input, output and supply lines separately and not parallel to each other.
- Do not connect any additional loads to the supply terminals of the instrument.
- The instrument is not suitable for installation in hazardous areas.
- Apart from faulty installation, there is a possibility of interference or damage to controlled
processes due to incorrect settings on the controller (setpoint, data of parameter and
b70.2040en.bk Seite 7 Mittwoch, 19. November 2008 10:15 10

configuration levels, internal adjustments).
Safety devices independent of the controller, such as overpressure valves or temperature
limiters/monitors, should always be provided and should be capable of adjustment only by
specialist personnel.
Please refer to the appropriate safety regulations in this connection. Since auto-tuning (self-
optimization) cannot be expected to handle all possible control loops, there is a theoretical
possibility of unstable parameter settings. The resulting process value should therefore be
monitored for its stability.
- All input and output lines that are not connected to the supply network must be laid out as
shielded and twisted cables (do not run them in the vicinity of power cables or components).
The shielding must be grounded to the earth potential on the instrument side.

4.2 Principle of operation
Normal display
The display shows the process value.
Operating level
The setpoint SP is input here. On active setpoint switching via the logic input, SP 1 or SP 2 ap-
pears in the display. When the ramp function is active, the ramp setpoint SPr is displayed. With
activated timer function, the timer value tior the timer start value ti0 is shown.
The setpoint is altered dynamically using the iand dkeys. The setting will be accepted auto-
matically after approx. 2 sec.
Parameter level
The setpoints, the limit value of the limit comparator, the controller parameters and the ramp slo-
pe are programmed here.
Configuration level
The basic functions of the controller are set here.
In order to make the settings, it is necessary to change to the configuration level
Avia the parameter y:0 (parameter level).
Timer level
The current timer value (only when the timer has been started) and the timer start value are al-
tered here. The parameters at this level are marked with an underscore in the display.
Time-out
If no operation occurs, the controller returns automatically to normal display after approx. 30 sec
(exception: with timer functions starting via power ON, the timer value is displayed). If the timer
value is displayed at the operating level, time-out is not active.

4.3 Operation of the timer function
The timer can be operated with the keys (start, stop, cancel, acknowledge) if the timer at opera-
ting level is indicated. Time-out is not active here. If the logic input is configured accordingly,
then a key, such as the ikey, can be used. In this case, the timer can also be operated even if
the timer value does not appear in the display.
