Provide appropriate protective measures (i.e precautions which allow for the require-
ments of the respective application) even for the case of failure and malfunction.
Failure of the pump (e.g. due to power failure) or of connected components, of parts
of the supply or change of parameters must not lead to a critical dangerous situa-
tionunderanycircumstances.Incaseofdiaphragmcracksorleaksinthemanifold
pumped substances might be released into the environment or into the pump hous-
ing or motor. Comply especially with notes on operation and use and maintenance.
Due to the residual leak rate of the equipment,theremightbeanexchangeofgas,
albeitextremelyslight,betweentheenvironmentandthevacuumsystem.
Adopt suitable measures to prevent contamination of the pumped substances or the
environment.
The controller is powered by a short circuit proof wide-range power supply with
integrated overload protection.
The motor is protected by a temperature sensor at the circuit board: Current
limitation if the temperature at the circuit board is higher than 70°C, switching off the
pumpifthetemperatureishigherthan85°C.Incaseofblockadeofthemotor(after
10 attempts to start-up) the pump is switched off.
If the pump is switched off due to safety measures, manual reset is necessary. Isolate
the pump from mains. Eliminate the cause of failure before restarting the pump.
