ACS Features
Drive Active (System ON)
Output
The output can be mapped to most of the parameters.
The most common is Drive Enable. This relay output will
be closed when ACS module is running. It is used as the
Start or Run input to the VFD. It is not the Secure Dis-
able input. See F
IG . 4-F IG . 6 on pages 8-10 for further
information.
Back Pressure Regulator (BPR)
Production/Sleep Modes
NOTE: See F IG . 4-F IG . 6 on pages 8-10 and manual
311606 for wiring and installation details.
Flow Rate Monitoring
Operational Envelope Limit
Explosion-proof electric motors have constant torque
and variable torque limits. E-Flo system is a constant
torque application, and therefore the motor’s constant
torque limits must not be violated. The system is avail-
able from Graco with two motors: the UL/CSA explo-
sion-proof motor and the ATEX explosion-proof motor.
Pressure Limits
If a pressure transducer is present, set the maximum
pressure limits as shown in T
ABLE 6. See Alarm
Enable, page 29.
