Alarm screens
The programmable controller monitors activities while the pump is running. When the controller detects a problem with
the system, the operator interface shows a status symbol and the stack light blinks. When operating the intensifier or
primary motor is likely to damage the system, the intensifier and the primary motor turn off.
Press F1 on the operator interface to stop an alarm. The alarm screen closes and the stack light stops blinking.
The amber stack light blinks to signal a condition that requires attention. The red stack light blinks to show that a fault has
occurred.
