WARNING: AUTOMATIC RESTART
Risk of injury. When the power is restored aer a power cut, the pump will restart
automacally. 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 operaon. 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 serial control, the pump will accelerate to full operang speed when started.
To start the pump, send the command (over the serial communicaons link) that follow:
Command ! c 8 5 2 sp 1 cr
The reply is as follows:
Reply * c 8 5 2 sp 1 cr

of the full rotaonal speed by default, but a dierent value can be selected to suit the
applicaon.
