Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING ELECTRIC SHOCK HAZARD This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric shock. • Turn off and disconnect power at main switch before disconnecting any cables and before servicing or installing equipment. • Connect only to grounded power source. • All electrical wiring must be done by a qualified electrician and comply with all local codes and regulations.
Warnings WARNING PRESSURIZED EQUIPMENT HAZARD Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury. • Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Installation Installation Power Supply Requirements Installation of this equipment involves potentially hazardous procedures. Only trained and qualified personnel who have read and who understand the information in this manual should install this equipment. NOTE: To install an advanced motor, also see Intrinsically Safe Installation Requirements for Advanced Motors, page 12. Fill With Oil Before Using Equipment Before using the equipment, open the fill cap (P) and add Graco Part No.
Installation Connect the Power Supply Improper wiring may cause electric shock or other serious injury if work is not performed properly. Have a qualified electrician perform any electrical work. Be sure your installation complies with all National, State and Local safety and fire codes. 4. Bring the power wires into the electrical compartment through the 3/4–14 npt(f) inlet port. Connect the wires to the terminals, as shown. Torque the terminal nuts to 25 in-lb (2.8 N•m) maximum. Do not over-torque. 5.
Installation Grounding This equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current. NOTE: For advanced motors EM0012 and EM0022, all motors must be bonded to the same high integrity equipotential system. See Intrinsically Safe Installation Requirements for Advanced Motors, page 12.
Operation Operation Startup Pressure Relief Procedure 1. Unlock the fused safety switch (B) and turn it on. See Connect the Power Supply, page 11 2. Press the start pushbutton (C). 3. Check that the power indicator (L) is lit (steady on). 4. See Advanced Motor Operation, page 13 or Basic Motor Operation, page 14 for further instructions. This equipment stays pressurized until pressure is manually relieved.
Operation Basic Motor Operation The basic motor has three operating modes: • Pressure Mode Pressure Mode with Integrated Runaway Protection Protection In pressure mode with integrated runaway protection, the motor will adjust the speed to maintain a constant fluid pressure, but will shut down if it exceeds a user-set speed. • Flow Mode 1. Turn the Control Knob (N) fully counterclockwise to 0. NOTE: Before changing from one mode to another, turn the Control Knob (N) fully counterclockwise to 0. 2.
Operation Flow Mode When in flow mode, the motor will maintain a constant speed regardless of the fluid pressure, up to the pump’s maximum working pressure. See Technical Data, page 43. 1. Turn the Control Knob (N) fully counterclockwise to 0. 2. Pull the Mode Select switch (M) out to set. Turn the switch to Flow lock. . Push the switch in to 3. The amount of flow is determined by the cycle rate set with the Control Knob (N).
Maintenance Maintenance Preventive Maintenance Schedule Check Oil Level The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system. Check the oil level in the sight glass (K). The oil level should be near the halfway point of the sight glass when the unit is not running.
Error Code Troubleshooting Error Code Troubleshooting Error codes can take three forms: • Alarm : alerts you to the alarm cause and shuts down the pump. • Deviation : alerts you to the problem, but pump may continue to run past the set limits until the system’s absolute limits are reached. • Advisory: information only. Pump will continue to operate. NOTE: On Advanced motors, flow (K codes) and pressure (P codes) can be designated as alarms or deviations. See Setup Screen 4 in the Control Module Manual.
Error Code Troubleshooting Applicable Motor Blink Code Display Code Alarm or Deviation Description Advanced 2–4 CAG? Alarm Display detects a loss of modbus communication when control access is set to modbus. Basic and Advanced 4 WXD? Alarm An internal control board hardware failure is detected. Advanced 1–5 WSD? Alarm Invalid lower size; occurs if the unit is operated before setting up the lower size. Basic and Advanced 5 T3D? Deviation Over temperature.
Repair Repair Replace Output Seal Cartridge 4. Drain the oil from the motor. See Change the Oil, page 16. 5. Reinstall the oil drain plug. Torque to 25–30 ft-lb (34–40 N•m). 1. Stop the pump at the bottom of its stroke. Shut off and lock out power to the motor. 2. Follow the Pressure Relief Procedure, page 13. 3. Disconnect the lower from the motor, as explained in your separate E-Flo DC pump manual. 3A2526F 6. Unscrew the output cartridge (19) from the motor. See Parts, page 20. 7.

Control Board Replacement Kits 24U934, 24U936, 24U935, 24U937 1. To disconnect the control board unplug the position sensor, encoder, temperature sensor, and motor from the control board. Reinstall Electronics Cover 2. Remove wires from clip inside housing. 3. Remove any tie straps that may be present. 4. Set the electronics cover/control board aside. For advanced models see Disconnect Power Barrier Board, page 35.
Encoder Replacement Kit 24U938 Encoder Replacement Kit 24U938 Overview 2. Follow the Pressure Relief Procedure, page 13. The encoder is used by the E-Flo DC for two purposes. First, the encoder tells the control board where the motor is in its mechanical rotation and uses that information to properly control the motor torque. Second, it controls stroke length by allowing the control board to count the number of complete motor rotations. 3.
Encoder Replacement Kit 24U938 Remove Motor Cover 1. Remove the 4 bolts that hold on the motor cover using a 6mm hex wrench. Place bolts in a safe location. 2. Set motor cover aside. AA Set screws AB Encoder mounting flange AC Phillips head mounting screws AD Motor housing Install New Encoder 1. Place the encoder connector cable (AE) through the motor housing lower port (AF). NOTE: The encoder connector is the smaller of the two connections. Figure 20 Motor Cover Remove Encoder 1.
Encoder Replacement Kit 24U938 Reinstall Electronics Cover Be sure that no wires are pinched between the electronics cover and the motor housing. Pinched wires may damage the control board and will impair explosion-proof safety. 1. Reinstall electronics cover onto center housing. 2. Install the 12 bolts using a 6 mm hex wrench.
Position Sensor Replacement Kit 16U705 Position Sensor Replacement Kit 16U705 NOTICE Overview The position sensor is used by the E-Flo DC to determine where the motor is in the stroke.
