Alarms & troubleshooting

CAN_COMM_FAIL (CAN Bus Communication Failure)
Controller Alarm LED Red solid, module Comm LED blinking red or off
Loose or damaged RJ45 CAN cable, missing 120-ohm bus termination resistor, duplicate module node address, or damaged CAN transceiver
1. Inspect RJ45 patch cables and daisy-chain connections between the Inview S controller and power modules. 2. Verify that 120-ohm bus termination resistors are correctly placed at both physical ends of the CAN bus. 3. Log in to the Inview S web/LCD interface to review module scan status, identify unresponsive modules, and reseat or replace them.
DC_VOLT_LOW (DC Bus Undervoltage / LVD Alarm)
Controller Alarm LED Red solid, Major alarm relay energized
Prolonged AC utility outage exceeding battery backup, rectifier capacity overload, severely depleted battery string, or incorrect LVD disconnect threshold configuration
1. Check AC input power source; start standby generator or investigate rectifier operational status. 2. Measure DC bus voltage using a calibrated multimeter to verify accuracy against Inview S telemetry. 3. Shed non-critical DC loads to prevent total low-voltage disconnect (LLVD/BLVD), and verify float/boost charge limit settings upon mains restoration.
MOD_FAULT (Power Module Internal Hardware Fault)
Controller Alarm LED Amber solid, faulty module Fault LED Red solid
Internal semiconductor breakdown, output overvoltage shutdown (HVSD) latch, internal cooling fan stall, or auxiliary power board failure inside the module
1. Access the Inview S event log to identify the specific module slot, serial number, and diagnostic code. 2. Disengage and withdraw the faulty module; inspect the rear connector and blind-mate backplane for arcing or pin damage. 3. Insert a spare module of identical rating and firmware; verify automatic recognition and load sharing on the controller UI.
BATT_TEMP_HIGH (Battery High Temperature Alarm)
Controller Alarm LED Amber solid, temperature-compensated float derating active
Battery room HVAC cooling failure, thermal runaway developing during float/boost charge, or shorted/drifted NTC temperature sensor
1. Measure individual battery cell casing temperatures with an infrared thermometer to detect thermal runaway or swelling. 2. Inspect the NTC sensor probe wiring at the Inview S analog input terminals; disconnect and measure resistance to verify sensor integrity. 3. Verify battery compartment HVAC operation; if batteries are hot, force float charge voltage down or disable boost charge in the controller menu.
SPD_TRIP (Surge Protective Device Failure)
Controller Alarm LED Amber solid, SPD module mechanical flag displays red
High-energy lightning surge or utility transient causing MOV degradation, triggering the auxiliary microswitch dry contact to the controller
1. Inspect the SPD cartridges on the AC/DC distribution panel to identify the failed module with the red visual indicator. 2. Verify the continuity and tight seating of the dry contact signal wiring connected to the Inview S digital input (DI) port. 3. Hot-swap the damaged plug-in cartridge with a replacement of identical Uc/Imax ratings and verify alarm clear on Inview S.
