KDCV System Configuration
- 1. System Controller:
Receives input from the Touchpad(s) and Hood Controller(s) to control the output for the VFDs.
- 2. Hood Controller:
Oversees Temperature and Optic Sensors on each hood and sends sensor data to the System Controller via RS-485 communication.
- 3. Touchpad:
Provides switches for the operation of hood lights and fans, bypass, mornitoring LEDs, and programming.
- 4. Optic Sensors:
Monitor the presence of smoke and vapors inside the hood. Send a signal to the Hood Controller to increase fan speed when cooking.
- 5. Air Purge Units:
Miniature blowers send air into Optic sensor housings to prevent smoke and grease from collecting on lenses.
- 6. Temperature Sensor:
Monitors the exhaust air temperature in the duct and sends a signal to the Hood Controller to vary fan speed in proportion to heat load.
- 7. VFDs:
Variable Frequency Drives receive signals from the Hood Controller to control the speed of the fans based on the heat and smoke load.
