Contact
functionnal status
Their functions are to copy
the data concerning the
pump operating status.
When the controller detects a bearing operating
fault, it opens the contact.
After a stop, it opens when the rotation speed
reaches 10000 rpm.
This contact can be used to control a secondary
isolation valve
which is used to maintain the
pressure in the chamber while the pump is reset
to atmospheric pressure.

are activated.
* Stop / Ext. fault functions allow to close the contacts at 10000 rpm + setted delay.
When the units containing the control circuits
are equipped with dry contacts outputs, it is the
customer’s responsability to use the outputs in
compliance with safety regulations.
CAUTION!
