SECTION 2: OPERATING INSTRUCTIONS
2-1: WARNINGS
Grounding Instructions
1. This product should be grounded. In the event of an electrical short circuit, grounding reduces the
risk of electric shock by providing an escape wire for the electric current. This product is equipped
with a cord having a grounding wire with an appropriate grounding plug. The plug must be
plugged into an outlet that is properly installed and grounded in accordance with all local codes
and ordinances.
2. WARNING -Improper installation of the grounding plug can result in a risk of electric shock.
When repair or replacement of the cord or plug is necessary, do not connect the grounding wire
to either flat blade terminal. The wire with insulation having an outer surface that is green with or
without yellow stripes is the grounding wire.
3. Check with a qualified electrician or serviceman if the grounding instructions are not completely
understood, or if in doubt as to whether the product is properly grounded. Do not modify the plug
provided; if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
4. This product is for use on a nominal 115-volt circuit, and
has a grounding plug similar to the plug illustrated. Only
connect the product to an outlet having the same
configuration as the plug. Do not use an adapter with
this product.
Unplug the machine before performing any service operations.
Do not use in environments with solvent vapors. This machine is not designed to be used in
environments with solvent vapors.
Do not use in hazardous locations
This machine is not designed to be used in hazardous locations (Class I Division I).
Do Not Slam the door up or down with excessive force. This could damage the interlock
switch and the limit switch.
Do Not Slam the container into the receiving bucket.
Do Not Load or attempt to blend containers that are improperly or partially sealed as the
container may spill inside the machine. Build-up of spilled materials could affect the drive
mechanism.
Do not mix partially filled containers since the motion of the liquid inside may destabilize
the machine.
Do not open the door before the motion has ceased.
Wait at least 8 seconds after the motor stopped before opening the door since the

SECTION 4: TROUBLESHOOTING
4-1: IDENTIFYING PROBLEMS
4-1-1: THE MIXER DISPLAY IS BLANK
On power up the display should show 00:00 or STOP. If the display is blank, then one of
the following items may be the cause:
1. The circuit breaker has tripped.
Check that the circuit breaker on the right hand side of the machine has not tripped. The
circuit breaker is tripped when the center section is projecting from the device and a
white plastic stem is exposed. If the circuit breaker is extended, then push fully in.
The circuit breaker tripping is usually caused by heat or torque overload. The motor or
bucket may be physically locked in place. Check that it is free to move, and that there
are no foreign materials around or in the gears.
2. The machine is not properly plugged into the receptacle.
Plug the mixer into the receptacle.
3. The outlet is not live or operational.
Test the outlet with a Volt meter or standard appliance to make sure the outlet is
operational.
4. The power cord is damaged.
Replace the power cord as described in Section 5-3-4.
5. A fuse has blown or is disconnected.
Check that the fuse is installed properly. Follow the procedure in Section 5-3-2.
6. There is a wiring fault on the internal wiring / electronics.
To determine this proceed as follows:
• Unplug the paint blender.
• Remove the back cover (Refer to Section 5-1 for cabinet removal instructions).
• Check that the power cord is connected into the Molex connector going into the
main power junction box (TruMix 1/5/XHD) or directly to the terminal blocks
(Ergo 5). Refer to Appendix 4-2-A/B/D detailed wiring information.
Note: There are two Molex connectors going into this box. One supplies power to
the unit, the other goes to the motor. If the power cord is plugged into the motor
connector, the motor will begin to turn immediately, indicating the wrong
connector. If this occurs, plug in the other Molex connector.
• Check that the cable from the power junction box is connected into the display
circuit board. This is terminated onto terminal J1.
• Check that the cable from the keypad is connected into the display circuit board.
This is terminated onto terminal JP4.
4-1 Page 1 Revision 2.00

4-1-2: THE MIXER DISPLAYS THE MESSAGE “STOP”
When the stop button is pressed during a mix cycle this alarm is displayed until it is safe to
open the door. If the message remains for more than 60 seconds then proceed as follows:
• Unplug the paint blender.
• Remove the back cover (Refer to Section 5-1 for cabinet removal instructions).
• Refer to Appendix 4-2A/B/D detailed wiring information and proceed as follows:
o Ensure that the stop switch has the two wires connected to the switch terminals.
o Check that the two wires coming from the switch are connected into the display
circuit board at terminal JP2.
o If the message does not disappear, the circuit board may need to be replaced. Call
HERO’s Customer Service Department at 1-800-494-4376 to further troubleshoot
this problem.
4-1-3: THE MIXER DISPLAYS THE MESSAGE
“dL”
If the door is open when the mix cycle is initiated or opened during the mixing cycle, the dL alarm will
be displayed on the digital panel (This is normal). If the door is closed and the dL message remains,
proceed as follows:
• Unplug the paint blender.
• Remove the back cover (Refer to Section 5-1 for cabinet removal instructions).
• Check that, when the door is closed, the switch actuation magnet is directly under the
magnetic switch, and that it is securely fastened to the door. This applies to both magnetic
switches for the Ergo 5
• Refer to Appendix 4-2A/B/D for detailed wiring information and proceed as follows:
• Check that the two wires coming from the magnetic switch (for the Ergo 5, switch closest to
the display circuit board) are connected into the display circuit board at terminal JP3.
• Check that the switch is working properly by disconnecting the switch plug from the
display circuit board at terminal JP3 and testing it for continuity using a multi-meter. With
the door closed (magnet under the switch) the switch should be closed (continuity). With
the door open (magnet away from the switch) the switch should be open (no continuity).
• Upon reconnection of power, if the dL message does not disappear then the display
circuit board may need to be replaced. Contact HERO’s Customer Service Department at
1-800-494-4376to further troubleshoot this problem.
4-1 Page 2 Revision 2.00

4-1-4: THE MIXER MOVES ON THE FLOOR
• Check that the can is full and fully pushed down into the can holder.

4-1-5: THE MIXER DISPLAY COUNTS DOWN BUT DOES NOT MIX
• Unplug the paint blender.
• Remove the back cover (Refer to Section 5-1 for cabinet removal instructions).
• Check that the mechanical drive system is intact. Turning the can holder by hand and
observing that the motor shaft is turning can do this.
• Make sure the motor power cord is connected to the connector cord coming out of the
power junction box (TruMix 1/5/XHD) or directly to the terminal blocks (Ergo 5). Refer to
Appendix 4-2A/B/C/D for detailed wiring information.
If the problem persists contact HERO’s Customer Service Department at 1-800-494-4376 to
further troubleshoot this problem.
4-1-6: THE DOOR WILL NOT OPEN
This situation can occur only in models with the interlock option.
When there is no power applied to the machine, the interlock solenoid de-energizes and the door
locks. When power is applied to the machine, the solenoid energizes and the door unlocks. When the
mix cycle commences, the solenoid is de-energized (locked). At the completion of a cycle (i.e. display
counted down to zero) the door remains locked for a short period to allow the motor to come to a rest.
If the mix cycle is prematurely stopped with the stop button, the solenoid is energized for someperiod
depending on the mixer settings.
If the door lock is not operating as above and remains locked for a long time, then proceed as follows:
• Unplug the paint blender.
• Remove the back cover (Refer to Section 5-1 for cabinet removal instructions).
• With the machine unplugged, check that the solenoid is free to move up and down by
hand.
• Re-connect power and visually check that when the power is applied the solenoid plunger
pulls up out of the way of the door.
If the problem persists contact HERO’s Customer Service Department at 1-800-494-4376 to
further troubleshoot this problem.
