Please read these Operating Instructions carefully before starting up the instrument. Keep
these operating instructions in a place which is at all times accessible to all users. Please
assist us to improve these operating instructions where necessary. Your suggestions will be
most welcome.

All necessary settings are described in these operating instructions. However, if any difficulties should still arise during start-up, you are asked not to carry out any unauthorized manipulations 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.
When returning chassis, assemblies or components, the regulations of EN 100 015 “Protection 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 discharge).
- 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
3 Electrical connection
7
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 (selfoptimization) 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.

gone above or below a programmable tolerance limit. When the timer has run down, several
events are triggered, such as control switch-off (output 0%) and setpoint switching. Furthermore, it is possible to implement timer signalling via an output.

Notes on the timer function in conjunction with the ramp function
- Generally, the setpoints can also be approached using the ramp function.
- Stopping the timer does not influence the ramp function.
- If control is active after the timer has run down, the current setpoint is approached with the
ramp. Cancellation of the timer is followed by a setpoint step without ramp.
- For timer functions with a tolerance limit, only the setpoint (=ramp end value) is monitored.
Note on setpoint switching via the logic input
- Setpoint switching via the logic input is generally possible. An exception here is the timer
function “Time-dependent setpoint switching”. In this case, configured setpoint switching via
the logic input will not be active.
Note on the display status in the event of a power failure
- The state of the display before the power failure will be restored, except for events that are
related to the timer (start, cancel, continue, stop). Then the timer value will be shown in the
display.

Start condition of the timer vpage 34
The timer start value ti0 is counted down as selected in the following events:
1. Power ON or logic input/keys
2. Start via keys/logic input
3. Process value has reached tolerance limit (1°C or 5°C) (start via keys/logic input)
The position of the tolerance limit depends on the controller type:
- 2-setpoint controller: tolerance limit below setpoint
If, during the control process, the process value goes above/below the tolerance limit, the
timer will be stopped for the duration of the infringement.
Response to a power failure vpage 34
After a power failure, the condition before the power failure can be restored, or the
timer function can be cancelled. If the timer had run down before the power failure, the timer
start value will be loaded. The timer will start automatically when C121=1 or 5.
The timer value is saved at one minute intervals, to cover the case of a power failure.

After the start via the logic input or from the keys, the process has to be controlled for 30 minutes to a setpoint of 80°C. The control action is to be cancelled in the event of a power failure.
