Power supply of the MSE6-E2M

Operating voltage
Power supply for electronics and sensor.
Load voltage
Power supply for actuators.
Warning
Risk of injury
If the load or operating voltage of the MSE6-E2M is switched off, then the shut-off valve
switches to the initial position (pressurise). If the valve was previously closed, the sys­
tem is pressurized. If the system was vented, pressurisation takes place suddenly.
• Use appropriate measures to ensure that unintentional pressurisation of the system
is not possible.
Note
Check as part of your emergency off concept (action in emergency to switch off electric
energy to all or part of an installation) what measures are required to put your system in
a safe status (e.g. switching off the load voltage for the valves, switching off the com­
pressed air, etc.) in case of emergency off (if there is a risk of electric shock or other risk
of electric origin).
If there is an undervoltage, the MSE6-E2M switches to the "Pressurise" status.
Note
Note that the partially tighter tolerance range must be observed when the operating
and load voltage supplies are provided by a shared power supply unit.
Tolerance ranges:
