Further information

When it makes sense to replace the SIDOOR control unit

Typical situations in which replacing the control unit is the right course of action:

• the door mechanism is generally working, but the control unit is faulty or unreliable
  
• modernisation of an existing machine (e.g. new interfaces / new peripherals)
  
• Diagnosis and commissioning are to be made easier
• Standardisation of door solutions within the service/maintenance fleet

What are the key considerations when replacing a control unit?

For a replacement to work in practice, the following points are particularly important:

• Interface/control: PROFINET, EtherCAT, CAN or discrete I/Os
  
• Power supply/voltage and mounting type
  
• Installation location: inside the control cabinet vs. externally on the machine
  
• Peripherals & Safety: emergency stop, sensors, connection of additional safety devices

With this information, the right solution can usually be identified very quickly.

TSG V4 as an alternative – what’s in it for you

TSG V4 is designed for use on machine doors in machine tool environments – with a focus on practicality and support. Typical benefits in the context of control units:

• internal or external design (depending on the installation concept)
  
• interfaces such as PROFINET, EtherCAT, CAN and discrete inputs/outputs
  
• commissioning & diagnostics (including web interface / Ethernet / Wi-Fi)
  
• Parameterisation and operating functions on the device – without additional software for key steps

Matching guide – SIDOOR control units → TSG V4

If you can specify a particular SIDOOR control unit, matching it becomes particularly straightforward.

Examples of common SIDOOR model names:

• SIDOOR ATD401W → TSG V4 (relay) 
• SIDOOR ATD420W → TSG V4 (PROFIBUS, on request) 
• SIDOOR ATD430W → TSG V4 (PROFINET)

Here you will find an overview of all SIDOOR control units and their respective TSG replacements.

Checklist – we need this information to make our selection

• SIDOOR designation / Siemens part number 
• required interface (PROFINET/EtherCAT/CAN/discrete) 
• Voltage / power supply 
• Installation type (internal/external)

Frequently Asked Questions

Is there an alternative to Siemens SIDOOR for machine tools?

Yes. Langer + Laumann offers suitable control units and drives for machine doors on machine tools and provides support with replacement, retrofitting and technical implementation.

Can I replace an existing SIDOOR control unit?

Yes. For existing applications, the appropriate L+L solution can be identified based on the interface, voltage and installation situation.

Are there also replacements for SIDOOR drives?

Yes. For several SIDOOR drives listed in the product documentation, Langer + Laumann provides relevant information and alternatives.

Does LANGER + LAUMANN also provide support for commissioning and diagnostics?

Yes. A web interface, Ethernet and Wi-Fi, amongst other options, are available for commissioning and diagnostics.

For which machines is the solution suitable?

The focus is on machine doors on lathes, milling machines and machining centres. In principle, however, the solution is suitable for all doors in which SIDOOR door drives or SIDOOR control units are used. In addition, Langer + Laumann also offers suitable alternatives for many other manufacturers.
