Electronic Components Testing
Touch Screen
•
If
the
touch screen
is scrambled or not reading the complete screen check
•
Touch screen
reads “ERR” (Error) check electrical connections, if the problem
persists replace the faulty unit.
•
Touch screen
reads “ERF” (Electrical Interference) check electrical connections
if the problem persists contact Infinity Solutions Manufacturing.
•
If nothing is displayed on the screen, check that the unit is powered and receiving a signal.
Power Supply
1. With
the
power switch / breaker
on and lit, confirm the power LED light on the
power supply
is lit.
a. If not lit, ensure power is coming into the unit and the connections are good, if that is
confirmed and the power light still is not on, replace.
2. Test output voltages from power supply, the correct voltages are printed on the unit.
a) If the voltage is zero or are found to be incorrect replace the unit.
PLC
1. With
the
power switch / breaker
on and lit, confirm the “run” LED light on the
power supply
is lit.
a. If lights are not on, check wire connections and ensure the unit is receiving power,
once both are done and the light remain off replace the unit.
2. Ensure that the “error” light is not lit, if it is lit try switching the “run / program” switch into the
“program position and then back into the “run” position to reset the PLC.
a. If the “error” light remains on please contact Infinity Solutions Manufacturing.
3. Ensure the “run / program” switch is in the “run” position.
Driver
•
If all four LEDs next to the capacitor are lit this indicates a faulty unit,
replace the driver.
•
If the machine is power on and no LED lights are lit check for proper
wiring and that the unit is getting power.
Drive Motor
•
If it is suspected of that the
drive motor
is faulty it will either make
excessive noise or not run at all.
o
See section 10.5.5 to isolate noise issues. If the motor is the
source, replace with a new motor drive. (See Section: 9.1)
•
To test the motor drive:
o
Remove
the
drive train cover
and remove the
drive belt
.
o
Rotate
the
motor drive pulley
by hand, there will be some
resistance
If the motor is locked, ensure no wires are shorted,
crossed or improperly connected.
Replace the motor if it is locked up.
o
Disconnect all wires from the
drive motor
and connect the lead wires (black and white)
attempt to rotate the motor pulley, it should be locked up and not rotate freely. If it rotates
freely replace motor.
o
If both the above steps are successful, check for power to the motor.
If the motor is receiving power ensure the driver is not faulty and all electrical
connections are sound and wired correctly, see electrical schematic.
