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
AC input power to the drive.
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.
WARNING
The machines are designed so as
to prevent any thermal risk to the
user's safety. However, specific
operating conditions may generate, temperatures
justifying particular attention on the part of the user
(external surfaces > 70°C on exhaust connections).
Always use gloves before servicing.
WARNING
Contact may cause burn.
Do not touch or wear protective gear
before servicing.
HOT SURFACE
If any pyrophoric, toxic, oxider or flammable
material can be sent to the pump, then an
exhaust monitor should be used in the
secondary exhaust to ensure that gas flow to
the pump is stopped when secondary exhaust is lost.
Also, if flammable materials are sent to the pump, the
customer will need to provide a hardware based LEL
detection in the secondary exhaust (capable of detecting
at 25% of the LEL) that will stop chemical supply to the
pump when gas is detected at 25% of LEL for that
flammable material.
