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 or danger-
ous situation 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 housing 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.
•
Attention:
If
Auto-Start
is preselected, the process starts immediately after a
power failure without pressing any further key. It is the user’s responsibility to
ensure that no dangerous status of the system due to the automatic start-up can
occur and to provide appropriate safety measures. If necessary, the user has to
check
prior to starting process control
whether the option ”Auto-Start” is ena-
bled.
• Switching of an isolation valve or a vacuum pump (in combination with a VMS
Module A) or opening of the venting valve of the controller must not lead to a criti-
cal dangerous situation under any circumstances.
Check liquid level in both catchpots regularly and drain condensate in time. In case,
install level sensor (see “Accessories“).
The controller is powered by a
short circuit proof wide-range power supply
with
integrated overload protection.
In case of overload the motor is shut down by a
self-hold thermal cutout
in the
winding.
Attention: Reset possible only manually. Switch off the pump or isolate the equip-
ment from mains. Identify and eliminate the cause of failure. Wait approx. five min
-
utes before restarting the pump.
Attention
: In case of
supply voltage below 100V
, the lock of the cutout might be
restricted and the pump might restart on its own after sufficient cooling down. Take
suitable precautions, if an automatic restart of the pump may lead to a critical dan-
gerous situation.
Do not start the pump if the pressure difference between inlet and outlet port ex-
ceeds 1.1 bar at maximum.
Prevent any backpressure of gases and the backflow of condensates.
Never suck liquids or dust into the pump.
The A-weighed emission sound pressure level of the pump does not exceed 70
dB(A). Measurement according to EN ISO 2151:2004 and EN ISO 3744:1995 with
standard silencer or exhaust tube at outlet.
