The Sargent Electrical Services Ltd. EC200 Electronic Control System is a microprocessor-controlled digital system designed to provide a comprehensive control solution for various leisure vehicles. It allows users to manage equipment and access/modify system information through a user-friendly control panel featuring an alphanumeric liquid crystal display.

Function Description:

The EC200 system primarily consists of a Power Supply and Control Unit (PSU2007) and a Digital Control Panel. The PSU2007 integrates Mains 240V protection equipment, a 200-watt 12V charger/power supply, and 12V equipment power control/protection. The Digital Control Panel connects to the PSU2007 via a data cable, enabling user interaction.

Key functions include:

Power Control: Users can turn the main power on and off, with an adjacent LED indicating the power status.
Battery Management: The system allows selection between Leisure or Vehicle batteries as the power source. An LED indicates when the Vehicle battery is selected (Leisure battery is the default). It includes a battery save feature to protect the Vehicle battery and prevents over-discharge of the leisure battery, which can cause permanent damage if discharged below 10.5V.
Water System Control: Users can turn water pump(s) power on and off. The system also supports filling the internal tank from an external tank for a one-minute period. Water levels for both fresh and waste water tanks are displayed.
Time and Alarm Functions: An internal clock can be set, and an alarm clock feature allows users to set specific times. An asterisk (*) on the main display indicates when the alarm is set.
Event Timer: This feature allows users to schedule the 12V power to turn on or off at predetermined times, even when the user is not in the vehicle. This is useful for controlling lights or other equipment. A hash (#) on the main display indicates when the event timer is set.
Auxiliary Power Control: Auxiliary power can be turned on and off, with an adjacent LED indicating its status.
System Monitoring: The control panel displays the model number (EC200), software version, current time, internal temperature, and external temperature (for H specification systems). It also shows the current (in Amps) being drawn from or charged into the selected battery (for H specification systems).
Safety Features: Built-in intelligence prevents over-discharge of the vehicle battery. The system includes 240V protection equipment (RCD and MCBs) and 12V power control/protection. It also features an automatic shutdown if the PSU overheats, restarting when cool.

Usage Features:

User-Friendly Interface: The control panel features a liquid crystal alphanumeric display and intuitive buttons for navigation and selection (SCROLL UP/DOWN, SELECT).
Remote Control (Optional): An optional plug-in remote control pack allows operation of Power and Auxiliary functions via a key fob controller.
Warning Messages: The system provides warnings for low vehicle battery voltage (e.g., "Vehicle Battery Dangerously Low") and system disablement when the engine is running ("System disabled Engine started!"), complying with EMC requirements.
24-Hour Cycle: The clock and event timer operate on a 24-hour cycle.
Display Backlight: The display backlight operates for approximately 6 seconds after any key press.

Maintenance Features:

Fuse/MCB Table: A detailed table provides information on fuse ratings, colours, wire colours, and descriptions for both 12V DC supply fuses and 240V MCBs. Users are warned to always replace fuses with the correct value and to contact a dealer if a replacement fuse repeatedly blows.
Fault Table: A comprehensive fault table helps diagnose common issues, listing possible causes and proposed fixes for problems such as no 240V output, no 12V output, control panel display issues (no display, corrupt/erratic function, poor contrast, incorrect current reading), and PSU overheating.
Battery Servicing: Routine inspection of battery terminals and fluid top-up (where applicable) is recommended. Users are advised against over-discharging the battery.
Control Panel Reboot: Instructions are provided for rebooting the control panel by removing and reconnecting its lead, or by removing leisure and vehicle battery fuses.
Ventilation: Users are warned to ensure clear airflow through the PSU2007 ventilation slots to prevent overheating and automatic shutdown.
