Zeus Omega Hall Effect Sensor — Alternator Drive Module A2241

The ARCO Marine Zeus Omega Hall Effect Sensor (A2241) features non-contact, split-core sensing technology that simplifies monitoring by eliminating the need to physically cut wires or install inline shunts.The technical specifications and complete installation breakdown for the AZHSADM are detailed below.

Technical Specifications: The sensor reads the electromagnetic field around the main charging cable to safely stream high-accuracy current data
Compatibility: Connects directly to the ARCO Zeus Omega Alternator Drive Module (AZADM).System Voltages: Supports 12V, 24V, 36V, and 48V DC systems natively.Measurement Type: Direct Current (DC) non-contact electromagnetic Hall Effect sensing.
Installation Architecture: Split-core clamp (does not interrupt the main conductor or affect circuit resistance).Calibration: Zero calibration required at commissioning (factory calibrated and plug-and-play).Environment Rating: Designed for high-heat engine rooms and harsh marine/off-grid applications

Mount the Sensor BaseLocate the main positive (B+) charging conductor coming off the back of your alternator. Open the split-core latch on the AZHSADM sensor housing. Position the sensor over the conductor cable and snap it firmly closed around the wire.
2. Verify Directionality, Pay attention to the current flow arrow molded into the plastic case of the sensor. Ensure the arrow points in the path of the current flow: away from the alternator and toward the battery bank. Note: If installed backwards, the reading will display as a negative value in the configuration app, which can be toggled via software settings if accessibility is tight.
3. Connect to the Drive Module (AZADM) Route the sensor's pre-terminated connection cable back to your nearby Zeus Omega Alternator Drive Module (ADM). Align the locking notches on the plug, push it securely into the dedicated sensor input port on the ADM, and twist the locking collar until it clicks. Secure any loose cable slack away from moving belts or hot engine parts using heavy-duty zip ties.
4. App Verification and CommissioningPower on your vessel or vehicle's DC electronics system. Open the ZEUS powered by ARCO app on your smartphone or tablet via Bluetooth or Wi-Fi. Navigate to the active Alternator screen to view real-time current metrics streaming over the local network bus.
