After elimination of the fault, the buscoupler can only be set to the normal working condition by another POWER ON sequence.
The green I/O LED flashes when accessing the I/O modules internal data channels. After being switched on, the buscoupler queries the configuration of the bus modules but does not carry out a data exchange with the I/O modules. This means that the red I/O LED will extinguish after a faultless startup. The green I/O LED will indicate when data is being exchanged by the Interbus network.
Status and error diagnostics:
The fieldbus LEDs show the state of the bus system. The functions of Interbus S are shown by the LEDs „READY“, „BA“, „RC“ and „RD“.

This chapter describes the general conditions for error-free running of the
:$*2Ç, 2Ç6<67(0
The following declarations concern modules which are transported and stored in the original package.
Condition

Temperature
Relative humidity
allowed values
≤ 1m
-40° to +70° C
5 to 95% (without condensation)
The modules of the :$*2Ç, 2Ç6<67(0 are not allowed to be operated without taking suitable actions
-in places with strong conditions e.g. very dusty rooms or corroding atmosphere
-in place with high concentrations of ionisation
The temperature should be in a range between 0° C and +55° C. The relative humidity should be in a range of 5 to 95% (without condensation).
The modules should be placed horizontal for better heat dissipation.
The concentration of SO2 must be below 25 ppm with a relative humidity of < 75%. The concentration of H2S must be below 10 ppm with the same humidity.
The mechanical conditions are given as sinusoidal oscillations.

For stronger impulses and oscillations, the acceleration and the amplitude should be reduced by suitable actions. The following table shows the type of test for the mechanical conditions.

These requests for electromagnetic compatibility are fulfilled by all modules of :$*2Ç, 2Ç6<67(0 (except for 750-630 and 750-631).
If non-stabilized power supply is used for the supply of the buscoupler, it must be
stabilized by a capacity ( 200 µF per 1 A load current).
For the :$*2Ç, 2Ç6<67(0 a filter module has been developed (288-824).
This module serves as a filter module for non-stabilized 24 V DC power supplies if the specified voltage deviation is not met.
Reasons for the deviations may be voltage jumps in the primary circuit, overloads in the secondary circuit or the switching of undampened inductances and capacitances.
The modules of :$*2Ç, 2Ç6<67(0 have passed the conformance test of UL. Look for listing mark on product.
The Profibus coupler 750-301 and 750-303 are certified of PNO with Z00241 and Z00242.
The Interbus coupler 750-304 has passed the relevant tests in accordance with the Interbus conformance requirements (number 111).
The DeviceNet coupler 750-306 has succesfully passed through the conformance test of Open DeviceNet Vendors Association Europe.
