Safety Guidelines
Safety Guidelines
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes

Use of Cu10 sensors
● Select "Three-wire thermal resistor" and "Cu10" at parameter assignment.
● Wire the Cu10 sensor in accordance with the three-wire connection method.
● Automatic, internal compensation of line resistance for the missing measuring line occurs
during operation.
Note
Please note the following to ensure optimum line compensation in the case of Cu10:
•The sum of the cable resistance and measurement resistance must not exceed 31 Ω.
•The cable must have a resistance of no more than 8 Ω if you want to use the
temperature range up to and above 312 °C.
Example: A 200 m Cu cable with a 0.5 mm2 conductor cross-section has
approximately 7 Ω. A smaller cross-section shortens the permissible cable length
accordingly.

Using PTC resistors
PTCs are suitable for temperature monitoring and as thermal protective devices for complex
drives and transformer windings.
● Select "Two-wire resistor" and "PTC" at parameter assignment:
● Connect the PTC in accordance with the two-wire connection method.
● Apply PTC resistors of Type A (PTC thermistors) in accordance with DIN / VDE 0660,
Part 302.
● If the diagnosis "Overrun/underrun" is enabled, a diagnosis "Lower limit exceeded"
indicating a short-circuit is indicated at resistance values < 18 Ω.

● Notes on programming
NOTICE
Only the bits 0+2 or 3+5 are relevant for the purposes of evaluation in the process input
image. You can use bits 0+2 or 3+5 to monitor the temperature of a motor, for example.
Bits 0+2 or 3+5 in the process input image does not have a retentive function. Make
sure at parameter assignment that motor start-up is controlled (by means of an
acknowledgment), for example.
Bits 0+2 or 3+5 cannot be set at the same time, but set one after the other.
For safety reasons, always evaluate the diagnostic inputs of the 2AI RTD HF because
measurement is not possible when the EM is removed, when the power supply to the
EM has failed, or in the event of a wire break or short-circuit of the measuring lines.

Temperature coefficient
The correction factor for the temperature coefficient (α-value) specifies how much the
resistance of a certain material changes when the temperature is raised by 1° C.
The temperature coefficient depends on the chemical composition of the material. Only one
value is used in Europe for each type of sensor (default value).
Additional values enable you to make a sensor-specific setting for the temperature
coefficient, therefore ensuring more accuracy.
2.2 Parameter description
Smoothing
The individual measured values are smoothed by digital filtering. The smoothing can be
adjusted in four steps, in which the smoothing factor k multiplied with cycle time of the
electronic module equals the time constant of the smoothing filter. The higher the smoothing
the greater the time constant of the filter.
The following diagrams show the step response with the various smoothing factors
depending on the number of subassembly cycles.
