designed for use in explosive atmospheres.
OPERATION
Start-up Procedure. Before starting the pump/motor assembly, ensure that any valves in the inlet or discharge lines are open and
that any inlet filters are clean and free from obstruction. Refer to the pump IOM for its operational instructions.
Starting or running the pump with the discharge valve closed may
result in overloading of the drive motor and overpressure in the
discharge pipe.
Operating the motor without an attached pump will expose rotating
parts that can cause injury to personnel. Never touch the rotating
components.
1. Set the external control voltage to minimum (0VDC).
2. Turn on the 24VDC power supply. With the control voltage set to 0VDC, the motor should not turn. In this idle state the
motor will draw a nominal 60-80 mA current.
3. Adjust the control voltage input to the required level. Current demand will rise and fall as the pump load and speed varies.
Once started the pump should prime if it has not already been filled with fluid. If the pump fails to prime, stop the pump and fill the
pumphead with liquid.
Post Start-up Checks. Once the pump has started perform the following checks:
