What to do if Graco Industrial Equipment primary heater(s) does not heat?
If the primary heater(s) do not heat, check the following: * Heat turned off: Press the A or B zone keys to turn the heat on. * Temperature control alarm: Check the temperature display for a diagnostic code. * Thermocouple signal failure: Check for a disconnected Fluid Temperature Sensor (FTS) or thermocouple.
Why is my Graco Industrial Equipment reactor not operating?
The reactor may not be operating due to several reasons: * No power: Ensure the power cord is plugged in and the main power is turned ON. * Circuit breakers: Check and turn ON the circuit breakers. * Red stop button: An open red stop button circuit can also cause this. Check the button connections.
What causes low pump output in Graco Industrial Equipment?
Low pump output can be attributed to: * Obstructions: Clear any obstructions in the fluid hose or gun, and use a hose with a larger ID. * Pump valves: Consult the pump manual regarding worn piston or intake valves in the displacement pump. * Pressure setpoint: Reduce the pressure setpoint to increase output.
What to do if Graco Industrial Equipment display does not respond properly to button pushes?
If the display isn't responding to button presses: * Poor display connection: Check cable connections and replace any damaged cable. * Damaged display cable: Clean connections; replace the cable if damaged. * Ribbon cable: Connect or replace a disconnected or broken ribbon cable on the display circuit board. * Broken display button: Replace the button.
Why does my Graco Industrial Equipment hose heat slower than usual or not reach temperature?
Slower or insufficient hose heating can be due to: * Cold ambient temperature: Consider using an auxiliary hose heat system. * FTS issues: Check the FTS. * Low supply voltage: Verify the line voltage.
What to do if Graco Industrial Equipment hose does not heat?
If the hose does not heat, check these items: * FTS issues: Check the FTS for correct contact and functionality. * FTS installation: Ensure the FTS is properly installed near the end of the hose, in the same environment as the gun. * Temperature control alarm: Check the temperature display or diagnostic code.
What causes erratic hose temperature in Graco Industrial Equipment?
Erratic hose temperature can result from: * Faulty thermocouple connections: Ensure all FTS connections are snug and clean. Check connections of thermocouples to the long green plug on the heater control board, cleaning any debris and re-plugging the wires and connector. * Incorrect FTS installation: Verify the FTS is installed close to the end of the hose, in the same environment as the gun. * Damaged insulation: Ensure the hose bundle has adequate insulation evenly covering the entire length and connection joints.
How to troubleshoot a Graco Industrial Equipment fan that is not working?
If the fan isn't working, check for these potential issues: * Blown fuse: Replace the fuse. * Loose wire: Check the wiring. * Defective fan: Replace the fan.
Why is my Graco Industrial Equipment hose temperature exceeding the set point?
If the hose temperature exceeds the set point, consider these causes: * Overheating heaters: Check primary heaters for thermocouple problems or a failed element. * Faulty thermocouple connections: Ensure FTS connections are snug and clean. Also, check the connections of thermocouples to the long green plug on the heater control board, cleaning off any debris and re-plugging the wires and connector. * Damaged insulation: Ensure the hose bundle has adequate insulation evenly covering the entire length and connection joints.
What causes erratic display on Graco Industrial Equipment; display turns on and off?
An erratic display that turns on and off may be due to: * Low voltage: Ensure the input voltage is within specifications. * Poor display connection: Check cable connections and replace any damaged cables. * Damaged display cable: Clean corroded connections or replace the cable if damaged. * Ungrounded display cable: Ground the cable. * Excessively long display extension cable: Ensure the cable does not exceed 100 ft (30.5 m).
