Service Interval
The service interval feature can be
based on a timer function or an external event. If
the setpoint adjustment for service interval
responds, the unit is configured as an elapsed time
indicator and will signal proper service intervals
for the dust collector. The timer can signal any
routine service required. If the setpoint adjustment
function does not work, the unit is configured to
respond to an external signal, such as a high level
indicator.
Blower Overcurrent
This light indicates that the
blower motor is exceeding the recommended
horsepower output, including any service factor.
This usually indicates that the system airflow
exceeds the rated operating range. Changing the
damper settings or increasing the external static
pressure are ways of reducing the airflow.
Operating the collector before installing ductwork,
with filter cartridges removed, with the doors
removed, or with the hopper open to the
atmosphere will also create excess flow conditions.
Blower Rotation
This fault light indicates that the
blower rotation is incorrect.
Note:
Three phase motors only.
Compressed Air
This fault light indicates that the
compressed air pressure has fallen below the
recommended minimum value.
Unlabeled lights are for customer-defined fault
indication. Contact Donaldson for further
information.
