Technical Information
This pump is designed for operation with neutral or noncorrosive materials.
WARNING
The IDP-10 is NOT intrinsically safe and should never be used with
potentially explosive or flammable substances or in potentially explosive or
flammable environments. It is the customer's responsibility to ensure safety,
even including in the case of pump failure.
Stop the pump by sliding the switch to the 0 position or, if using the remote input,
by applying a logic HI or open circuit to the remote input pin #2.
The optional inlet valve closes when the pump stops as long as vacuum is at the inlet.
Protection Features
The IDP-10 has several protection features:
Overload control: When the pump is under heavy pump loads but otherwise
able to run, such as pumping continuously at atmosphere or into a back
pressure, the pump automatically reduces the motor speed after a time delay
to reduce power dissipation. After running at this reduced speed for a fixed
time, full speed is again allowed. The reduced speed setting is 1740 RPM.
Overtemperature Protection: A thermistor is mounted to the motor housing that
shuts off the power to the motor if the motor temperature reaches
approximately 85° C. The fan continues running. Once the motor cools off, the
pump turns on again automatically.
Open Thermistor Detection: If the thermistor becomes open circuited or not
plugged in, the pump is not allowed to run.
Two stage overcurrent protection: To protect both the motor and the inverter
drive, a two stage current limiting scheme has been implemented for overloads
that may cause immediate damage to the pump or the inverter drive. When the
current exceeds a fixed level the pump slows down drastically, or even stops,
but then comes back up to speed automatically. This allows the pump to try to
recover from moderate overloads. If the overload is more severe, such as with
a locked rotor condition, safety is a concern, the motor is shutoff until the you
slide the switch to the 0 position or turn the pump OFF using the remote input.
