Request : Need ounting instructions for load feeders (DS 
   / RS) of ET200S

Suggestion : Please find the attached mounting instructions for DS / RS 
   load feeders.

Request : Which mounting positions are permissible?

Suggestion : For the system ET200S (6ES7) included the motor starters 
   3RK1301 and the modules 3RK1903 a vertical mounting position on rail is 
   permissible.
   
   The best position is the vertical mounting of the devices on horizontal 
   rails, so that the inscription is written correctly, but it is also possible 
   to turn the devices by 180°, so that the inscription is up side down. It is 
   also possible to turn the devices by 90°, so that the rail is mounted 
   vertical and the devices are mounted horizontal.
   
   Please take care of the temperature in the switch cabinet. In dependence of 
   the mounting position, the temperature and the current derating factors are 
   to consider and / or distance modules are to mount.
   
   For the horizontal mounting of the rail (vertical mounting of the devices) 
   you will find a table in the manual in chapter 2.4.
   
   For the vertical mounting of the rail (horizontal mounting of the devices) 
   the following derating factors should be considered:
   Circuit breaker smaller/equal 6,3A: unil40°C no derating
   Circuit breaker bigger/equal 6,3A: unil 30°C no derating
   Circuit breaker bigger/equal 6,3A: 30°C unil 40°C with 90% of Ie
                                                                                

Description
You have connected a lamp (e.g. 3SX1731 (130V/2.6W)) via lamp holder 3SB3400 with built-in ballast element to an output of a module with a rated load voltage of 120/230V AC. Here the output must be loaded in addition.

Order numbers of the modules concerned:

• 6ES7 322-1FF01-0AA0
• 6ES7 322-1FH00-0AA0
• 6ES7 322-5FF00-0AB0
• 6ES7 132-4FB00-0AB0

Cause
There is a diode for derating in the built-in ballast element. Due to this diode, the required holding current is not achieved when the Triac is started.

Remedy
Switch a low-loss RC element parallel to the output. This element is to consist of a resistor (1kW ) in series with a capacitor (0.1m F/AC 250V/x2). You can obtain this RC element as a product, order number 3RT1926-1CD00, as a suppressor circuit for contactor coils.

Configuration Notes:
Current ET 200 stations do not support multi-tiered setups such as were possible with the ET 200U, for example.
ET 200Ms can also only be configured with a single tier because connection to other module racks via interface modules is not permissible.

If the maximum configuration of the ET 200 station is inadequate, a further ET 200 station must be added to the PROFIBUS.

Configuration Notes
You have various options for capturing the reference point temperature to obtain an absolute temperature from the difference in temperature between the reference point and the measuring point.

• No compensation
• Internal compensation with electronic module 2 AI TC HF
• Using a resistance thermometer Pt100 for capturing the reference point temperature
• Using a compensating box in the supply conductors of each thermocouple

No compensation
You capture only the temperature of the measuring point. The temperature of the reference point (transition from copper conductor to compensating line) also affects the thermoelectric voltage. The measured value is therefore faulty.

Internal compensation with electronic module 2 AI TC HF
In the terminal modules TM-E15S24-AT and TM-E15C24-AT there is a temperature sensor. The temperature sensor gives the terminal temperature to the 2AI TC HF. This value is calculated against the measured value from the channel of the electronic module.
The parameterization of the ET 200 S station in the Hardware Configuration for this type of compensation is available in Entry ID: 19163406.

Using a resistance thermometer Pt100 for capturing the reference point temperature
You can capture the reference point temperature using a resistance thermometer (Pt100 climatic measuring range): in other words the thermocouples connected to the electronic module 2 AI TC compensate externally over the resistance thermometer PT100 that is connected to the electronic module 2 AI RTD. The PT100 must have a good thermal contact to the reference point (transition from copper conductor to thermocouple). If thermocouples are connected directly, the electronic module 2 AI TC HF is to be used (see "Internal compensation with electronic module 2 AI TC HF").
In the ET 200S with the appropriate parameterization, the temperature value captured with the PT100 is distributed to the 2 AI TC electronic modules and calculated with the temperature values captured at the measuring points (number of reference points:1).
If thermocouples that are connected to the inputs of 2AI TC ST have the same reference point, you compensate with a 2AI RTD. You can select "RTD" or "None" as reference point for both channels of the 2AI TC ST module. If you select "RTD", then the same reference point (RTD channel) is always used for both channels.

The parameterization of the ET 200 S station in the Hardware Configuration for this type of compensation is available in Entry ID: 19164641.

Using a compensating box in the supply conductors of each thermocouple
You compensate via a compensating box. The compensating box is the transition point from copper conductor to compensating line. There is no need for any further processing with the electronic module 2AI TC ST.
The influence of the temperature on the reference point of a thermocouple (terminal box, for example) can be compensated with a compensating box. The compensating box contains a bridge connection that is compensated for a specific reference point temperature (compensating temperature). The thermocouples or their compensating lines are connected to the compensating box. The compensating box is then the reference point. If the actual reference temperature differs from the compensating temperature, then the temperature-dependent bridge resistor changes. A positive or negative compensating voltage is generated, which is added to the thermoelectric voltage. Compensating boxes with a reference junction temperature of 0º C are to be used for compensating analog input modules.
The points below should be noted here.

• The compensating box must have a potential-free power supply.
• The power supply unit must have an adequate interference filter through grounded shielding winding, for example.

Note
More information about temperature compensation with the ET 200S is available in the manuals below.
