Suction effect from running fan wheel.
Risk of death or injury. A running fan wheel produces a suction effect that can pose
a risk of entanglement.
▶
Standing in the danger zone of the rotating fan wheel is prohibited.
Before entering the danger zone ensure the fan wheel has stopped, e.g., by
disconnecting the drive source.
Unexpected fan speed control behavior.
Risk of injury from fan wheel activating on system start or after repair.
▶
When unpowered, the motor can reach maximum speed depending on the position
of the drive unit (unpowered motor is swiveled out fully with pressure build-up).
Attention
: Unplugging the electrical control (ED) of the drive unit and/or
electrical control (EZ) of the hydraulic motor does not result in a safe off state,
rather it causes the fan wheel to run at maximum speed.
▶
Check whether or not your machine requires additional safety measures for
your application.
Fan wheel stationary while machine is running.
Risk of death or injury from sudden fan wheel movement.
▶
Never reach into the machine while it is running, e.g., to get the fan wheel to move.
▶
Use reversing to attempt to get the fan wheel to move again.
See also the required operating conditions and instructions on what to do as
described in project planning and commissioning instructions 90363.
▶
Check whether or not your machine requires additional safety measures for your
application.
We recommend programming the reversing function so it can only be started
when the viscosity/operating temperature in the hydraulic circuit is high enough
(testing during commissioning).
Bursting of hydraulic lines and/or damage to parts (e.g., shaft, fan blades).
Risk of death or injury, or property damage.
▶
Never unplug the solenoids while reversing operation is active.
▶
Never disconnect the power supply while reversing operation is active.
