Protections and Alarms

Protections and Alarms

Overview

The Digital Signal Processor (DSP) in the inverter continuously monitors a number of parameters for purposes of protecting the power source, load, inverter and user from hazardous conditions. Fuses on the DC input and AC output provide additional hardware fault protection. An alarm is triggered whenever a fault is detected. The protective action in the case of a fault is to turn the inverter off. The inverter then enters a self-diagnosis loop until the fault causing the alarm clears. This also clears the alarm in the fault register and allows the inverter to resume normal operation. If an alarm is tripped the fault flag on the user port as well as the red front panel indicator will be active.When equipped with the Ethernet option, the actual fault condition causing the alarm can be queried.

Input Voltage Protection

The inverter will continuously operate from an input source in the range of -35 to -75 Vdc. Should the input voltage fall outside this range for more than 4 seconds, the inverter output is disabled and internal relays open to isolate the load and source. In this condition, the red LED on the front panel is lit and fault flag on the user port is set high. The inverter resumes normal operation as soon as the input is within acceptable limits for 2 seconds.

Output Voltage Protection

The output is monitored for conditions potentially damaging to the inverter or load. A voltage exceeding 140 Vac (263 Vac for the 230 V model) at the inverter output for over 1 second, or a voltage below 80 V (154 Vac for the 230 V model) for more than 5 seconds will cause the inverter to shut down and open the internal load relay. This fault condition is reported by setting the fault flag on the user port and fault LED on the front panel. The DSP continues to check for compatible output conditions before enabling the inverter and switching to “on-line” status.
