Graco Motor Control Operation (BLDC Models)
Table 4 Graco Motor Control Key Features
Control Feature
Details
Leak Detection
• Receives a signal from the pump leak detector informing the controller of a
diaphragm rupture.
• The controller either warns or stops the pump, depending on a user setting.
• An event code is displayed.
Cycle Counting
• The controller tracks pump cycles and informs the user of any scheduled
maintenance intervals.
• User selects the number of cycles for the maintenance interval (i.e. diaphragm
replacement).
Batch Counter
• The controller tracks the dispensed pump volume.
– The counter can be reset by the user.
Batch Timer
• The controller starts batches at a time interval defined by G248.
– Time value is user defined.
– Starts pump when timer expires.
– Time value is set from start of current batch to start of next batch.
– A value that is shorter than the completion time of a currently-defined batch will
result in unintended results, but no error message is generated.
Max Power Mode
• This mode allows the user to disable the over current and motor temperature
faults. The result is a reduction in pump performance which is dependent on
the limiting factor.
• The system alerts the user that the pump is running at reduced performance and
the reason for the reduction.
• Motor Temperature Scaling
– The Graco Motor Control limits power to the motor when the motor winding
temperature is too hot.
♦ Limit Start – 120°C(248°F)
♦ Limit Stop (Full Shutdown) – 150°C(302°F)
Input Current (Power)
Limit
• The Graco Motor Control limits power to the motor depending on the voltage
and current available from line power.
– 12A (120/240V, 15A circuit) (default)
– 16A (120/240V, 20A circuit)
