Overview

E-Flo Pump Operational Overview

An electric motor (B) provides input to a 75:1 gear reducer (GR), which drives two fluid pumps (FP). See FIG. 1. The stroke positions of the two pumps are offset to achieve consistent flow from the pump assembly. See F
The optional sensor circuit includes a top dead center (TDC) sensor to measure motor speed, a position sensor (PS) to measure motor position, and a pressure transducer (PT) to measure fluid pressure at the pump outlet. The Graco ACS control module software mimics the effect of a camshaft, constantly adjusting motor speed to keep steady fluid flow and achieve minimal pressure variation. The output shaft of the gearbox and the connecting rods experience the electrical control module simulating the function of a camshaft by speeding up when the pressure drops (pump lower is at a changeover) and slowing down when pressure increases (both lowers are pumping).
The ACS module provides an analog drive signal to the VFD. Use one ACS module for each E-Flo pump. The ACS module can be controlled by a local control box mounted in the hazardous area, or via communication protocol (such as modbus).

page 9.
Use Belden 8777 cable or equivalent. It is impor-
tant to use multiconductor cable with 3 individu­ally shielded pairs.
Ferrite (15D906) must be installed on pressure
transducer wires.
Do not place signal wires in the same conduit as
AC Power wires. For example, the TDC/Position sensor wires should not share a conduit with the VFD wires.
Use the following VFD configuration settings:
analog input scaling
4 mA = 0 (zero) Hz
20mA = 80 Hz
Acceleration rate = 1.0 second (for full range 0-80 Hz)

NOTICE
NOTE: Each VFD brand will have varying setup param-
eters. ACS and E-Flo performance is optimized by the following key VFD settings:
analog input scaling
4 mA = 0 (zero) Hz
20 mA = 80 Hz
Acceleration rate = 1.0 sec (for full range 0-80 Hz)
Deceleration rate = 0.5 sec (for full range 0-80 Hz)
NOTE: If the ACS is used with an E-Flo 1500 pump and a 3 HP motor, activating the VFD slip compensation fea­ture may reduce motor heat and improve performance under certain conditions.

Diagnostic Procedures
High Pressure (System pressure is higher than the entered high pressure trip point.)
Low Pressure (System pressure is lower than the entered low pressure trip point. This alarm is dis­abled for 1 minute after the pump starts to prevent pre­mature alarms.)
Xducer Fail Loss of pressure transducer analog signal, cause by:
Max Flow (The requested
flow rate is beyond the pump’s capability.)
1. Check High Pressure Alarm setting. Verify that system desired operational pres­sure is lower then High Pressure Alarm setting.
2. Check for flow restrictions (closed valves, unexpected restrictions).
3. Check pump fluid section for proper operation (piston seals, ball checks). Refer to pump maintenance manual for additional information.
1. Check Low Pressure Alarm setting. Verify that system desired operational pres­sure is higher then Low Pressure Alarm setting.
2. Check fluid level. Low fluid level will cause system to run at low pressure.
3. Check fluid supply to the pump.
4. Check pump fluid section for proper operation (piston seals, ball checks). Refer to pump maintenance manual for additional information.
