Multifunctional Safety Monitors

Apart from a variety of classic monofunctional safety modules, such as emergency stop modules, DOLD also offers multifunctional safety modules and systems. For this, DOLD integrates more and more functionality in less space.

In the compact multifunctional SAFEMASTER C safety module several safety-related inputs are assigned to a single output. The selection of available safety functions includes:

  • Emergency stop
  • Safety gate
  • Electro-sensitive protective equipment (ESPE), e.g. light barriers
  • Two-hand safety button type IIIA or IIIC acc. to EN 574
  • Functions and operating modes can be easily selected by rotary switches.

SAFEMASTER PRO is a configurable, modular Safety system that consists of a controller and up to 14 extension modules. To optimise the adaption to different applications there are modules with only inputs, only outputs and mixed input/output models. The can be combined individually with max. 4 modules of the same type. The communication between the SAFEMASTER PRO modules is made via a 5 pole DIN rail bus (DOLD IN-RAIL-BUS). To extend the system an extension module is just clipped on the DIN rail. Additional field bus modules allow a simple diagnostic.

With SAFEMASTER M as a modular safety system it is possible to tailor the safety functions to the relevant application in a cost-saving manner. Evaluation includes:

  • Emergency stop
  • Safety gate
  • Electro-sensitive protective equipment (ESPE), e.g. light barriers
  • Two-hand safety button type IIIA or IIIC acc. to EN 574

Input modules with freely selectable safety functions can be assigned to different output modules. An optional field bus connection allows system status visualization.

Technology

SAFEMASTER® C

  • Complies with the European Directive on Machinery 98/37/EEC
  • Switchable via rotary switches for the connection of:
    - Emergency-stop buttons
    - ESPE (electro-sensitive protective equipment, e.g. light barriers)
    - Safety gates
    - Two-hand safety buttons type IIIA or IIIC acc. to DIN EN 574
  • Additional choice of:
    - Automatic or manual start (simulation button for safety gates)
    - Permanently monitored feedback loop to connect external contactors
  • Outputs:
    - 3x NO or 2x NO + 1x NC
    - 2 semiconductor outputs, short-circuit- and overload-proof
  • Undervoltage and overvoltage detection and signalling

Functions and operating modes can be selected by rotary switches under the front plate.

SAFEMASTER®Msafemaster M - maximal

Our safemaster M as a compact modular safety system extends our consistent safety solution concept.

It consists of 4 main modules:

  • Control module
  • Input module
  • Output module and
  • Diagnosis module

The control module BH 5911 has inputs and outputs. It features the emergency-stop function, either 1- or 2-channel with manual or automatic start. 4 start keys as a maximum can be connected, which can be assigned to the control module or to the input modules in any combination. Depending on the model the safety-related output has either 3 NO contacts or 2 NO contacts plus 1 NC contact, each in redundant configuration.

The input module BG 5913 has 8 safety-related inputs. Depending on the variant these inputs can be assigned to several safety functions. e.g. 1x safety gate + 1x ESPE + 1x emergency-stop or also 1x safety gate + 1x two-hand etc. These safety functions are processed in the input module and control the assigned output module(s).

The output module BG 5912 consists of two positive-action relays, which may have a variety of contact complements depending on the variant. These include 3 or 4 redundant NO contacts or 2 NO contacts/1 NC contact or 3 NO contacts/1 NC contact. It goes without saying that also delayed safety-related outputs are available, with the time being adjustable on the module. Here, the combinations 3x NO or 2x NO/1x NC are possible.

Where no potential-free relay output is required, we offer the module BG 5912.88 with safety-related off-delayed semiconductor outputs (stop category 1). The model BG 5912.89 features 4 safety outputs and is only 22.5 mm wide. Two outputs have no delay (stop category 0) and the other two are off-delayed (stop category 1).

Tailoring of the system to the relevant application is possible by using a control module which can be extended by up to 3 input and output modules each.

The diagnosis modules BG 5551 / BH 5552 are used for optional field bus interfacing to pass on the system condition, with the choice between CANopen or Profibus DP.
