SWG100BIO Ex. User Manual
The Remote Power Supply Box as optionally supplied by MRU, has a switch-off contactor (K1),
with 3 make contacts (normally open). The power contactor K1 is activated after the analyser is
powered on by pushing the power-on button until the green LED is light-on. In case of an
SWG100BIO-EX alarm, the power contactor K1 is deenergized. The circuit diagram shows the
correct wiring of the power contactor installed in the remote power supply box.
For more information see chapter 20.3
The circuit diagram of above pictured device must be implemented by user as part of the safety
concept.
User can either use the remote power supply box as offered by MRU, or install inside the power
distribution cabinet a similar circuit (see diagram in chapter 20.3) using a power contactor and
push-start button.
