1� IDENTIFYING THE INSTRUMENT
The nameplate with information is affixed to the side of the instrument. The supply voltage connected must
correspond to the voltage specified on the nameplate.
All necessary settings are described in these Operation Instructions. However, if any difficulties should still arise
during start-up, you are asked not to carry out any unauthorized manipulations on the unit. This could endanger
your rights under the instrument warranty! Please contact the nearest subsidiary or the head office in such a case.
Please read these operating instructions before commissioning the instrument. Keep the manual in a place that is
accessible to all users at all times. Please assist us to improve these operating instructions, where necessary.

3� ELECTRICAL CONNECTION
3�1 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 1000 V” or the
appropriate local regulations.

• Electromagnetic compatibility conforms to the standards and regulations listed under Technical data.
• The instrument is not suitable for installation in areas with an explosion hazard and must be built into a housing

• Apart from faulty installation, incorrect settings on the instrument (setpoint, parameter level data) may also
affect the proper functioning of controlled processes or lead to damage. Provision should therefore always be
made for safety devices that are independent of the instrument, e. g. overpressure valves or temperature
limiters/monitors. Adjustment must be restricted to specialist personnel (lock parameters for operation). Please
observe the corresponding safety regulations in this matter. Unfavorable parameter adjustment may result in
unstable control. The process value obtained should therefore be monitored for its stability and knowledge
about the process should be obtained.
• 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 a short circuit.
• Do not connect any additional loads to the supply terminals of the instrument.
• The external fuse of the supply should not be rated below 1A, depending on the conductor cross-section. If
contact with live components is possible while working on the instrument, it must be disconnected on both
poles from the supply (via a separate mains supply switch, for instance).

interface
The instrument is linked to a PC via a PC
interface with TTL/RS232 converter and
adapter (3-pole pins).
* Connect supply voltage – all segments light up twice as a test (segment test).
When everything has been connected up correctly on the instrument, the present process value will be shown. If an
alarm message appears, see Chapter 7 “Alarm messages”.
The relay operates according to the controller type that was set, see Chapter 4.2 “Setting the instrument functions
(parameter level)”.

If no key is pressed for 60 seconds, the instrument automatically switches back to process value display,
see Overview of operation on the first inside page.
The instrument functions and values are set at the parameter level.
* Press for 3 seconds and will appear alternately.
* Set code 72 for accessing the parameter level by using the and keys.
The longer the key is pressed, the faster the value will change.
* Acknowledge with ,
parameter name and value appear alternately, e.g.
* Set value within the specified value range by using the and keys.
* Acknowledge settings with .
* Set next parameter, see Overview of operation on the first inside page.
