2 Safety instructions

• The device described is a subcomponent for integration into a system�

- The manufacturer of the system is responsible for the safety of the system�

- The system manufacturer undertakes to perform a risk assessment and to create a documentation in accordance with legal and normative requirements to be provided to the operator and user of the system� This documentation must contain all necessary information and safety instructions for the operator, the user and, if applicable, for any service personnel authorised by the manufacturer of the system�

• Read this document before setting up the product and keep it during the entire service life�

• The product must be suitable for the corresponding applications and environmental conditions without any restrictions�

• Only use the product for its intended purpose (→ Functions and features).

• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur�

• The manufacturer assumes no liability or warranty for any consequences caused by tampering with the product or incorrect use by the operator�

• Installation, electrical connection, set-up, operation and maintenance of the unit must be carried out by qualified personnel authorised by the machine operator�

• Protect units and cables against damage�

3 Functions and features

In connection with a temperature probe the unit monitors the system temperature in machines and plants�

Connectable temperature probes:

• Temperature sensors TM, TS, TT�

• Resistance thermometer RTD (Pt 100 or Pt 1000).

The unit detects the connected sensor type and configures itself accordingly�

3

4 Function

• The unit converts the measured signal into a temperature-proportional analogue signal: 4��20 mA at [OU2] = [I] / 20��4 mA at [OU2] = [Ineg]�

• The analogue signal can be scaled� Factory setting → 10�

Minimum distance between ASP (analogue start point) and AEP (analogue end point) = 5 °C or 9 °F.

• The unit supports IO-Link�

4.1 IO-Link

This unit has an IO-Link communication interface which enables direct access to process and diagnostic data� In addition it is possible to set the parameters of the unit while it is in operation� Operation of the unit via an IO-Link interface requires an IO-Link master�

With a PC, suitable IO-Link software and an IO-Link adapter cable communication is possible when the system is not in operation�

The IODDs necessary for the configuration of the unit, detailed information about process data structure, diagnostic information, parameter addresses and the necessary information about the required IO-Link hardware and software can be found at www�ifm�com�

7 Parameter setting

Using an IO-Link capable parameter setting tool, the following options are available:

- Reading current process values�

- Reading, changing and saving current parameter settings and transmitting them to other units of the same type�

Output function for OUT2: Analogue signal: 4��20 mA [I] or 20��4 mA [Ineg]�

Analogue start value for temperature�

Measured value at which the output signal is 4 mA (20 mA at [OU2] = [Ineg]).

Analogue end value for temperature�

Measured value at which the output signal is 20 mA (4 mA at [OU2] = [Ineg]). Minimum distance between ASP (analogue start point) and AEP (analogue end point) = 5 °C or 9 °F.

Zero-point calibration�

Setting range: ±10 °C in steps of 0.1 °C. The internal measured value "0" is

shifted by this value�

Behaviour of output 2 in case of an internal fault�

- [On] = the analogue signal goes to the upper end stop value (21.0 mA).

- [OFF] = the analogue signal goes to the lower end stop value (3.5 mA.)

6

8 Operation

After power on, the unit is in the Run mode (= normal operating mode).

Response of the analogue output in case of a fault:

Value below the set measuring range

Value above the set measuring range

Value below or above the detection zone of the sensor

- The output signal falls to min. 3.8 mA (at [OU2] = [I]),

- rises to max. 20.5 mA (at [OU2] = [Ineg]).

- The output signal rises to max. 20.5 mA (at [OU2] = [I]),

- falls to min. 3.8 mA (at [OU2] = [Ineg]).
