Product Introduction

The Techcross ECS-RCM is the Rectifier Control Module of the Techcross ECS electrolysis-based ballast water management system (BWMS). It controls and monitors the power rectifiers that supply DC current to the electrolysis chambers, and shows output voltage and current on its front panel. SM MARINE SERVICE™ has wide experience with Techcross systems and supplies Techcross BWMS modules and spare parts worldwide.

What Is This Equipment?

In a Techcross ECS system, seawater is treated by electrolysis in the ECU (electrolysis unit), powered by DC rectifiers. The ECS-RCM is the operator panel and controller for these rectifiers: it starts and stops them, sets the operation mode, shows voltage, current and alarm status for up to four rectifiers (No.1–No.4), and communicates over CAN. A selector allows emergency operation or remote & local operation. The LCD in the photo shows “ECU:1”, indicating the module assigned to electrolysis unit 1.

Main Features

• Control and monitoring of up to 4 rectifiers (No.1–No.4)
• Digital voltage and current displays
• Backlit LCD for mode, ECU number and output voltage
• RUN / STOP / ALARM / CAN status LEDs for each rectifier
• Function keys ALL, No.1–No.4 and MODE, ↑, ↓, SET
• Emergency operation and remote & local operation selector
• Illuminated STOP and RUN push buttons
• CAN communication with other ECS units

Common Problems & Troubleshooting

• ALARM LED on: check the related rectifier, its power supply and the alarm shown on the CPC.
• CAN LED fault / no communication: check CAN cables, connectors and termination.
• No output voltage: check operation mode, selector position and rectifier status.
• Display not working: check module power supply and connectors.

Safety note: Rectifier panels carry high DC current. Isolate power before work. Use emergency operation only in emergencies as marked on the panel. Electrolysis can produce hydrogen – follow gas detection and ventilation instructions in the Techcross manual.

Common Alarms

Alarm details are shown on the CPC and in the Techcross ECS manual of the vessel; no alarm code list is published.

Maintenance Tips

• Check that all status LEDs and displays work during lamp test/routine checks.
• Keep the panel dry and dust-free.
• Check CAN and power connectors for tightness.
• Note the module settings and ECU assignment before replacement.

Spare Parts & Replacement Availability

For a quotation, please send a photo of the module label (e.g. RCM-T-V2 and number), the ECS system model and the vessel name. SM MARINE SERVICE™ ships worldwide from Bangladesh and China. Specific condition and availability are subject to confirmation.

Why This Equipment Is Still Used

Techcross ECS systems are installed on many ships to meet ballast water rules. A matching ECS-RCM module restores rectifier control without changing the approved system.
