Using a BMK: Troubleshooting
8.3.2 Resolving BMK Faults using the Router
For the three BMK faults that follow, refer to its respective remedy.
• Factory Fault (FacFault) – The BMK has lost its factory-set internal calibration reference.
Remedy: Reset the BMK by removing all power from the BMK. After resetting the
BMK, if the Factory Fault remains or returns, the BMK will require repair at the Magnum
Energy factory service facility.
• Power-up Fault (PwrFault) – The BMK’s power-up sequence failed.
Remedy: 1) Ensure the current sense wires are connected into pins 1 (blue wire) and
2 (orange wire), and the voltage wires are connected to pins 3 (black/negative) and 4
(red/positive). 2) Unplug the 4-port terminal block from the Sense Module, and then
check for the correct DC voltage on pins 3 (–) and 4 (+). The voltage must be between
7 to 70 volts DC depending on the nominal voltage of the inverter.
• Unknown Fault ## (Fault##) – This fault message displays when the inverter/charger has
sent a fault code that is not recognized by the router.
Remedy: Call the Technical Support department at Magnum Energy (425-353-8833)
for assistance in determining and understanding the actual fault status .
8.3 ME-BMK Troubleshooting (with the ME-RTR)
This section assists you in using the router to identify and resolve any faults or abnormal operational
conditions within your BMK system.
8.3.1 BMK Fault Message Screens for a Magnum Router
When an BMK fault is detected, the RTR’s FAULT LED (red) comes on and the fault status is displayed
on the LCD screen. Figure 8-7 is an example of how fault messages appear on the ME-RTR. Use
the RTR’s LCD screen and the information in this section to identify and correct the issue.
The FAULT LED lights solid red if the RTR’s display is on the port/device with the active fault, but
blinks if a different port/device has the active fault. Navigate to the port/device with the active
fault—the FAULT LED turns solid red when you are on the correct port/device.
