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 does my Graco Industrial Equipment hose not maintain temperature while spraying?
If the hose temperature isn't maintained during spraying, consider: * Setpoint adjustment: Increase A and B setpoints, as the hose is designed to maintain, not increase, temperature. * Ambient temperature: If it's too cold, increase A and B setpoints. * Flow rate: Use a smaller mix chamber or decrease pressure if the flow is too high. * Preheating: Ensure the hose is fully preheated before spraying. * Voltage: Verify the line voltage, as low voltage reduces power to the hose heat system.
What causes both sides of the display to not illuminate on Graco Industrial Equipment?
If both sides of the display do not illuminate, check for: * Power: Ensure the power cord is plugged in and the disconnect is turned ON. * Voltage: Ensure the input voltage is within specifications. * Wiring: Check the connections. * Display connection: Check the cable connections.
What to do if Graco Industrial Equipment hoses near Reactor are warm, but hoses downstream are cold?
If hoses near the reactor are warm, but hoses downstream are cold, it indicates a shorted connection or a failed hose heating element. With hose heat on and the temperature setpoint above the displayed hose zone temperature, verify the voltage between connectors at each section of hose. The voltage should drop incrementally for each section of hose further from the Reactor. Use safety precautions when hose heat is turned on.
What to do if Graco Industrial Equipment hose display reads OA at startup?
If the hose display reads OA at startup, verify proper installation of the FTS (see Operation manual 312065), or adjust the FTS to the desired current setting.
