Safety instructions for pump and
controller installation
Safety interlock.
The pump motor is protected against overload through the drive «start/
stop» and enable control circuitry of the variable speed controller. The drive
start/stop includes solid state components. If hazards due to accidental
contact with moving machinery or unintentional flow or liquid, gas or
solids exist, an additional hardwired stop circuit is required to remove
input power.
It is never required to override this interlock during installation, use or
maintenance.
Once activated power will be switch off and the pump will be put in a safe
condition. When a fault occurs, the cause must be corrected before the fault
can be cleared. It is required to switch power off and on to clear the fault.
If the product is used in applications where solid particles or condensable
gases are present, we advise on avoiding any deposition into the pumping
line. Contact our customer service.
The manufacturer guarantees the right operation of the pump if it is used
in an uniform magnetic field up to 0.5 mT.
From 0.5 to 5 mT the limit of the right operation depends on the cooling
and the gas loads.
Exceeding 5 mT can cause excessive rotor heating due to the eddy
current. It is therefore necessary to provide suitable shielding in such
cases.
The pump standalone is resistant to radiation at levels up to 10
3
Gy.
The units containing control circuits are designed to guarantee normal
safety conditions taking their normal operating environment into account
(use in rack).
In specific cases of use on tables, make sure that no objects enter the
ventilation openings or block the openings when handling the units.
Protection against foreign bodies
Controller can be deteriorated when any objects are introduced or any
liquids penetrate into the unit.
Make sure no objects enter through the ventilation holes. Keep the unit
away from the liquids.
