Victron CCGX Tank Pump Auto Start/Stop Setup Guide

Key Takeaways

• Automatic tank pump control on the Victron CCGX requires specific menu configurations.
• The Tank pump function must be enabled via the Relay settings before configuration.
• You define Start level and Stop level percentages for automatic operation.
• If settings do not yield expected results, verify each step and consider professional assistance.

How do I set up automatic tank pump control on my Victron CCGX?

Setting up automatic tank pump control on your Victron CCGX involves enabling the pump function through the relay settings and then configuring the operational parameters like start and stop levels. This feature allows the CCGX to manage a pump based on the detected level in a connected tank, ensuring it operates only when needed.

The first step is to activate the Tank pump function within the CCGX's Relay settings. Once enabled, a dedicated configuration menu becomes available where you can define the pump's behavior, including its operating mode and the specific tank level thresholds for activation and deactivation.

Diagnosis: Enabling and Configuring the Tank Pump Function

Follow these steps to enable and configure the tank pump functionality on your Victron CCGX.

1. Enable the Tank Overview Page (Optional):

• • Check: From the Main Menu, navigate to Settings -> Display and language.
  • Action: Look for the option Show boat and motorhome overview.
  • Meaning: If you enable this, an additional Overview page will be available, providing at-a-glance status information for all connected tanks. This is useful for monitoring but not strictly required for pump operation.

2. Enable the Pump Start/Stop Functionality:

• • Check: From the Main Menu, go to Settings -> Relay.
  • Action: Locate the Function setting for the relay you intend to use for the pump.
  • Meaning: Set this Function to Tank pump. This action dedicates the selected relay to tank pump control and makes the pump configuration menu accessible. Without this step, the pump settings will not appear.

3. Access the Tank Pump Configuration Menu:

• • Check: After enabling the Tank pump function in the relay settings.
  • Action: Return to the Main Menu, then navigate to Settings -> Tank pump.
  • Meaning: This path leads you to the dedicated configuration page where you will define how the pump operates.

Setting Up Automatic Pump Operation

Once you have accessed the Tank pump configuration menu, you can define the automatic operation parameters.

1. Select the Pump Mode:

• • Check: In the Tank pump configuration menu, find the Mode setting.
  • Action: Set the Mode to Auto.
  • Meaning: Selecting Auto mode instructs the CCGX to start and stop the pump based on the tank level settings you will define next. Other modes, On and Off, keep the pump continuously active or inactive, respectively.

2. Choose the Tank Sensor:

• • Check: Within the Tank pump configuration menu, locate the Tank sensor selection.
  • Action: Select the specific tank sensor that will be monitored to determine the tank level.
  • Meaning: This links the pump's operation to the readings from a particular tank. Ensure the correct sensor is chosen for accurate level monitoring.

3. Define Start and Stop Levels:

• • Check: In the Tank pump configuration menu, find the Start level and Stop level settings.
  • Action: Enter the desired percentage values for Start level and Stop level.
  • Meaning:
  • • The Start level is the tank level percentage at which the pump will be activated. For example, if you set it to 20%, the pump will start when the tank level drops to or below 20%.
    • The Stop level is the tank level percentage at which the pump will be deactivated. For instance, if you set it to 80%, the pump will stop once the tank level reaches or exceeds 80%.

Understanding Pump Modes

The Victron CCGX offers three distinct modes for controlling your tank pump. Choosing the correct mode is crucial for the desired operation.

Safety: Software Configuration

This article focuses on software configuration within the Victron CCGX. While configuring these settings, there are no direct electrical safety hazards. However, any physical interaction with the CCGX or its connected relays and pumps should always be performed with caution. Ensure all power sources are isolated before inspecting or working on wiring.

When to call a technician instead

If you have followed all the configuration steps and your tank pump is still not operating as expected, or if you encounter issues that seem to be hardware-related (e.g., a relay not clicking, pump not receiving power despite correct settings), it is advisable to contact a qualified Victron Energy installer or technician. They can diagnose potential wiring faults, sensor malfunctions, or internal CCGX issues that are beyond software configuration. Do not attempt to open the CCGX unit or modify its internal wiring unless you are a qualified professional, as this could void your warranty and pose electrical risks.
