All of the Alarm Conditions, when active, toggle back and forth between the two message states below.

Short Circuit Alarm

D1 Short

D2 A=0.500

Hold Opt to Clr

D2 A=0.500

• 2.0 Amp Trigger

• Shuts off and disables daughter board indefinitely.

• Motherboard LCD toggles alarm and instruction on how to re-enable the

daughter board.

• Affected daughter board’s alarm LED blinks on and off.

Thermal Alarm

D1 Thermal

D2 A=0.500

Hold Opt to Clr

D2 A=0.500

• Shuts off and disables daughter board indefinitely.

• Motherboard LCD toggles alarm and instruction on how to re-enable the

daughter board.

• Affected daughter board’s alarm LED blinks on and off.

High Current Alarm

D1 High Amp

D2 A=0.500

D1 A=1.100

D2 A=0.500

• Triggered when individual daughter board’s load current is above 1.0 Amps

for a minimum 10 seconds.

• 10 second timer is reset when below 1.0Amps.

• Does NOT shut off or disable daughter board.

• Motherboard LCD toggles alarm message and load current.

• Affected daughter board’s alarm LED blinks on and off.

Phase Current

Imbalance Alarm

D1L1 High Amp

D2 A=0.500

D1L1 A=0.750

D2 A=0.500

• Triggered when load current of one wire is 2x higher than the opposite wire

for a minimum 20 seconds.

• 20 second timer is reset when load current of one wire is no longer 2x

higher.

• Does NOT shut off or disable daughter board.

• Motherboard LCD toggles alarm message and load current.

• Affected daughter board’s alarm LED blinks on and off.

The display difference between the High Current Alarm and Phase Current Imbalance Alarm is subtle:

Notice the two-character difference in the display on the first line:

“D1” (High Current Alarm) vs. “D1L1” (Phase Imbalance).
