The CaterSense V2 & CS-V2+ATSC-02-08 is a multi-function gas supply controller designed to provide intelligent control solutions for the catering industry, adhering to relevant regulations. The system features a unique "self-set" commissioning process for ease of installation and setup.

Function Description:

The CaterSense V2 system is an intelligent controller that manages various aspects of a catering ventilation and gas supply system. Its core function is to ensure safe and efficient operation of gas appliances and ventilation fans by monitoring environmental conditions and system parameters.

Key functions include:

• Gas Pressure Proving: The system performs an integrity test of the pipework upon initialization. It opens the gas solenoid valve for 10 seconds, then closes it for 30 seconds, monitoring pressure. If the pressure drops by 10% or more during this stage, the system alarms and prevents startup. This feature ensures the safety of the gas supply before operation.
• Automatic Fan Speed Control: The controller can automatically adjust fan speeds based on various inputs, including CO2 levels, temperature, and system demand. This optimizes ventilation efficiency and maintains a comfortable and safe environment.
• CO2 Monitoring: The system continuously monitors CO2 levels within the kitchen environment. It has three stages of alert:
  • Warning Stage (2800-3799 PPM): The system condition light flashes from green to amber, and an alarm beeps every 3 seconds.
  • Alarm Stage (3800-4799 PPM): The system condition light flashes from green to red, an alarm beeps every second, and fan speed automatically increases to maximum.
  • Shutdown Stage (4800-4949 PPM): The system condition light flashes from amber to red. After 10 seconds, the control alarms (can be muted, but will resound 1 minute before gas valve closure), and fan speed increases to maximum. If CO2 levels remain too high for 5 minutes, the gas supply is shut off, and fans continue to run until CO2 reaches an acceptable level.
  • Instant Shutdown Stage (4950+ PPM): The gas solenoid valve instantly closes, and the system alarms.
• System Demand Control: The controller can respond to system demand, adjusting operations accordingly to maintain optimal conditions.
• Heater Battery Control: The system supports control of electric or gas-fired heater batteries, with specific jumper settings (J21) required for activation.
• Tempered Supply Air Control: A fully-modulating signal is sent to the heater battery to maintain the supply air temperature at a selected setpoint.
• Demand Extract Air Control: A fully-modulating signal is sent to the fans to control their speed based on the temperature within the canopy or cooking load.
• Interlock Circuits: The system integrates with fire alarms and knock-off switches, deactivating gas and fan outputs if these circuits are triggered.
• Diagnostic Tool: A built-in diagnostic mode allows for quick checking of stored settings and identification of problems, including fan current faults (low or high current).

Important Technical Specifications:

• Mounting:
  • Standard control unit: Six mounting holes.
  • Inbuilt speed control unit (CaterSense V2 + ATSC): Four mounting holes.
  • Enclosure must be mounted on a clean, level surface, away from direct cooking areas or wet surfaces.
• Cable Entry:
  • Standard control unit: 190 x 25 mm area on the top edge for conduit entry.
  • Inbuilt speed control unit: Two main areas for cable entry: top area (223 x 40mm) and back of enclosure (130 x 30mm at the top).
• Electrical Connections:
  • Terminals 1 to 22 (1.5 mm² cable): Used for sensors, interlocking devices, remote speed, and on/off control. Screened cable (e.g., Beldon 8723) is recommended.
  • Terminals 23 to 34 (4 mm² cable): Used for power connections for fans, gas valve, and power supply.
  • Rising Clamp Type Protection: All terminals feature rising clamp type protection.
  • ATSC-02-xx Terminals 1 to 16 (1.5 mm² cable): Used for sensors, interlocking devices, and motor thermal contacts. Screened cable (e.g., Beldon 8723) is recommended.
  • Remaining Terminals (4 mm² cable): Used for power connections for fans, gas valve, and power supply.
  • Power Supply: 240Vac, 50Hz.
• DIL (DIP) Switch Settings: Used to enable/disable Gas Pressure Proving, Automatic Fan Speed Control, CO2 Monitoring, and System Demand.
• Setpoint Adjustment: Two 270° turn pots (R113 and R114) are used to allocate different setpoints based on DIL switch settings.
• Fan Speed Control (ATSC-02-xx): Features min/max pots and a ratio pot to balance supply and extract air. Trent Products recommends a minimum voltage output to fans of no less than 140Vac between "M" and "C" terminals on the speed control PCB to prevent overheating.

Usage Features:

• "Self-set" System Commissioning: The controller simplifies setup with a unique self-set system.
• Step-by-step Setup Sequence: The manual outlines a clear sequence for initial setup and commissioning, providing audible "beeps" and colored LED feedback.
• Manual Speed Control Fan Power Monitoring: Allows users to manually adjust fan speeds and save settings, ensuring proper air balancing.
• Automatic Speed Control Fan Power Monitoring: The system automatically establishes fan characteristics by slowly reducing speed and recording running currents.
• Electronic Speed Control Fan Power Monitoring: Enables precise setting of minimum and maximum fan speeds (0-10 VDC) using pads and a multi-meter.
• User Feedback: The system provides visual (LEDs) and audible (beeps) feedback during setup and operation.
• System Start/Stop: A "Start" key initiates the system, and a "Stop" key deactivates it.
• Diagnostic Mode: Allows for manual opening of the gas valve for testing (max 5 minutes) and real-time monitoring of fan current draw.

Maintenance Features:

• Troubleshooting Guide: The manual includes a comprehensive troubleshooting section for common issues such as system stopped, fire alarm, knock-off button activation, fan undercurrent/overcurrent, gas pressure faults, high CO2 levels, and memory errors.
• Clear Wiring Diagrams: Detailed diagrams are provided for electrical connections, sensor connections, and PCB locations to aid in installation and maintenance.
• Jumper Link Configuration: Specific jumper links (J27, J26, J25, J23, J13) are used to activate/deactivate various devices and select input types, facilitating system customization and fault finding.
• Ribbon Cable Connection: Instructions emphasize correct ribbon cable connection (key pin/red stripe at the top on the main PCB, bottom on the facia) to prevent damage and ensure proper unit function.
• Regular Checks: The manual recommends checking fan operation, current levels, filter cleanliness, and gas pressure levels as part of routine maintenance.
• Professional Assistance: Users are advised to contact Trent Products for further technical assistance or if problems persist. For gas-related issues, contacting a GAS SAFE engineer is recommended.
