Digital Temperature Control and Auto Curing Timer System for Powder Coating Ovens
In powder coating applications, both temperature control and curing time are critical factors that directly affect the quality of the finished product. If the curing temperature is too low or the curing time is insufficient, the powder coating may not fully adhere to the substrate. Conversely, excessive temperature or prolonged curing can degrade the coating’s physical properties and appearance. Precise control of these parameters is therefore essential to achieving consistent, high-quality coating results.
To address these requirements, PP Systems has developed a dedicated Temperature and Curing Time Control Panel designed for powder coating ovens utilizing up to six gas-fired infrared burners. The system incorporates a high-quality Digital Temperature Controller from FOTEK (Taiwan), a trusted brand widely recognized throughout Thailand’s industrial sector for its reliability and accuracy.
The controller provides precise temperature regulation while the integrated Auto Curing Timer automatically manages the curing cycle according to predefined process parameters. This ensures consistent curing performance and minimizes operator intervention.
In addition to temperature and time control, the panel offers comprehensive burner status monitoring, end-of-cycle alarm notification, and independent burner zone control. Each burner can be operated separately, providing greater process flexibility, improved temperature uniformity, enhanced operational safety, and reduced production errors.

Common Problems with Non-Standard Control Panels
Are You Facing Any of These Challenges?
Inaccurate Temperature and Curing Time Control
Poor temperature regulation and inconsistent curing cycles can result in incomplete curing, uneven coating quality, and increased production rejects.
Low-Quality Components with Limited Spare Parts Availability
Inferior components are more prone to failure and difficult to replace, leading to costly downtime and increased maintenance expenses.
Lack of Electrical Drawings and Technical Documentation
Troubleshooting, maintenance, and future system modifications become more difficult without proper documentation, reducing overall system reliability and production continuity.

This helps maintain consistent product quality and improves process efficiency.
In addition, the system includes comprehensive wiring diagrams, clearly identified terminal connections, and long-term spare parts availability. These features simplify maintenance, reduce downtime, and provide users with confidence throughout the entire service life of the equipment.
External Device Connections
Spark Ignition Controller Terminal Connections
| Terminal | Connection | Description |
|---|---|---|
| G1 – G6 | Green Wire | Supplies 220VAC Line power to the Spark Ignition Controllers |
| R1 – R6 | Red Wire | 220VAC feedback signal indicating normal burner operation (Flame Detected) |
| Y1 – Y6 | Yellow Wire | 220VAC feedback signal indicating burner ignition failure (Flame Failure) |
| N | Blue Wire | Neutral connection for the Spark Ignition Controllers |
Operating Functions
| TEMP CONTROL | TIMER | Operating Description |
|---|---|---|
| OFF | OFF | • After the Main Switch is turned ON, the Temperature Controller displays the current temperature. • PV (Present Value) = Actual measured temperature. • SV (Set Value) = User-defined temperature setpoint. • The system is powered and ready for operation, but the burners remain disabled. |
| ON | OFF | • Burners No.1–6 are controlled according to the configured temperature setpoint. • When PV < SV, the gas valves and ignition system are activated, and the green status indicator illuminates. • When PV ≥ SV, the gas valves are de-energized and the status indicator turns off. • The burners will automatically restart when PV falls below SV. |
| ON | ON | • The Timer starts counting immediately when activated. • Burners operate under normal temperature control. • When the preset curing time expires, the burner system is shut down automatically and an alarm signal is activated. |
| ON | AUTO | • The Timer does not start counting immediately after activation. • The Timer begins counting only when the process temperature reaches the setpoint (PV ≥ SV). • Ideal for powder coating curing applications where curing time must start only after the product reaches the required temperature. • When the preset curing time expires, the burner system is shut down automatically and an alarm signal is activated. |
