Universal temperature transmitter

FlexTop 2211

Operating instructions

Field of application

FlexTop universal temperature transmitter type 2211 is a compact temperature transmitter, designed to be built into the housing of a temperature sensor, like the Baumer CombiTemp.

Safety instruction

This instrument is built and tested according to the current EU-directives and packed in technically safe condition. In order to maintain this condition and to ensure safe operation, the user must follow the hints and warnings given in this instruction.

During the installation the valid national rules have to be observed.

Ignoring the warnings may lead to severe personal injury or substantial damage to property.

The product must be operated by trained staff. Correct and safe operation of this equipment is dependent on proper transport, storage, installation and operation.

All electrical wiring must conform to local standards. In order to prevent stray electrical radiation, we recommend twisted and shielded input cables, as also to keep power supply cables separated from the input cables. The connection must be made according to the connecting diagrams.

Before switching on the power supply take care that other equipment is not affected. Ensure that the supply voltage and the conditions in the environment comply with the specification of the device.

Before switching off the supply voltage check the possible effects on other equipment and the processing system.

Description

The FlexTop universal temperature transmitter type 2211 is suitable for input from RTD sensors, T/C sensors plus potentiometer or resistance signals.

The FlexTop 2211 features a 4 … 20 mA output signal.

Configuring with FlexProgrammer 9701

The FlexTop 2211 can be configured using the 4...20 mA cable. The maximum distance depends on the cable type, resistance and capacity.

We recommend to use shielded cables.

To be able to configure the FlexTop 2211 with the FlexProgrammer

9701 the dedicated software, Flex-program, must be loaded on the PC.

During the configuration the new data are, by means of the FlexProgrammer 9701, transferred from the PC to the FlexTop 2211, where they are stored in the internal memory.

WARNING

For electrical installation and commissioning of explosion protected devices, the data given in the conformity certificate as also the local regulations for installation of electrical apparatus within explosion protected areas must be considered. The intrinsically safe versions can be mounted in the explosion hazarded area according to its specification only connected to a certified intrinsically safe supply loop with the corresponding electrical values.

Dimensions

The indication for a correct configuration sequence is:

1) The LED on the FlexTop 2211 lights up constantly.

Error indications during configuration:

1) The LED on the FlexTop 2211 is not lighting.

2) An error message comes up on the PC.

Note: During the first power-up after a configuration the power-on time increases to approx. 10 sec.

WARNING

This product contains no replaceable parts.

In case of malfunction the product must be shipped to Baumer for repair www.baumer.com Operating Instructions: 11109144 03

Current measurement Voltage measurement

LED function

The LED of the FlexTop indicate the actual status of the measured value. The LED will be turned on continuously as long as the measured value results in an output current between 4 and 20 mA. If the output current is higher than 20 mA or lower than 4 mA the LED will flash with 1Hz. The same flashing behaviour will occur if a sensor break error is detected.
