WARNING: PUMP RESTART AFTER POWER CUT
Risk of injury. When the power is restored after a power cut, the pump will restart
automatically. Keep the pump connected to the vacuum system to prevent risk of
injury.
CAUTION: PUMP MOVEMENT
Risk of damage to equipment. Do not move the pump when it is in operation. The
gyroscopic forces generated by this movement can cause more use of the back up
bearing and can result in catastrophic failure of the pump.
In parallel control, the pump will accelerate to full operating speed when started.
To start the pump, link the start/stop control input to the 0 V control reference on the
logic interface connector.
The green indicator on the motor controller illuminates when the pump reaches normal
speed. This is 80% of the full rotational speed by default, but a different value can be
selected to suit the application.
6.3.2 Run the pump at standby speed
If the pump operates at less than or more than the standby speed it will accelerate or
decelerate until standby speed is reached.
1.
To operate the pump at standby speed, link the standby control input to the 0 V
control reference on the logic interface connector.
2.
To return the pump to full speed, disconnect the standby control input from the 0
V control reference on the logic interface connector.
6.3.3 Stop the pump
WARNING: MECHANICAL ENERGY IN ROTOR
Risk of injury. After the pump is set to off, the rotor will continue to rotate at high
speeds through an emergency or as a requirement. The rotor has mechanical energy
until it slows down and stops.
WARNING: EXPOSURE TO BACK E.M.F
Risk of injury or damage to equipment. Do not remove the controller from the pump
until the pump stops completely. The exposed electrical pins may pose a potential
hazard. The user could also be exposed to a back e.m.f. from the pump and
potentially damage the controller.
With parallel control, the pump rotor will decelerate when stopped.
To stop the pump, disconnect the start/stop control input from the 0 V control reference
on the logic interface connector.
