Protections and Alarms

Over Temperature Protection (OTP)

This feature protects critical components from failure due to temperature stress should a fan fail or the ambient temperature or internal temperature exceed acceptable levels. This module also controls the fans, turning them on when internal temperatures exceed 35°C and increasing fan speed in proportion to increase in temperature. When an OTP event occurs, the Inverter shuts down and the fault flag is set on the front panel and user- line port. Fans maintain operation at maximum speed until internal heat- sink temperatures drop below 70°C at which point the inverter re-starts.

Short-circuit Protection

The inverter output is short-circuit proof. The DSP detects a sustained short-circuit (greater than 2 seconds) and shuts down the inverter to protect the load. The inverter will attempt to power the load a total of three times in a 4-second window before permanently shutting down. After clearing the load fault, normal operation can be restored (see “To Clear an Alarm” on page 3–11).

Over-Current protection

The inverter can reliably deliver up to 50 A of peak current without tripping any protections. Two levels of protections are provided. The first level of protection is hardware based, providing peak current clipping at 50 A. Should the current exceed this (e.g. in the event of severe back- feed) the DSP forces the inverter to skip a line cycle. Three consecutive line cycle skips will force a reset of the inverter where the output is temporarily disabled for about 4 seconds or until the back-feed falls away.

Internal Diagnostics

Upon power-up or fault event, the inverter executes a sequence of internal diagnostics checking for compatible conditions at the DC input, output and selected internal modules. Different alarms cause execution of differing diagnostic sequences. All preceding fault conditions are continuously monitored as part of the internal diagnostics routine. In addition, the internal bus voltage, which is the inverter voltage source is also monitored. The diagnostic module checks to ensure this is within limits at start-up and continuously during normal operation. A failure of this bus sets the fault flag on the front panel and user-line port and disables the inverter. Normal operation resumes when within limits.
