Southwire Surge Guard (portable LCD) error code L1 HIGH / L2 HIGH (WAS xxxV)

FaultSurge Protection / Electrical Management (EMS)Verified against the manufacturer's manual

High voltage: the line voltage went above 136 V and the unit turned RV power off. 'WAS xxxV' records the voltage it saw (the manual's example is 'L1 HIGH WAS 137V'); L2 appears on the 50A models only. Once the voltage is back inside 102-136 V the unit runs DELAY and restores power after 128 seconds. Trip time: the spec tables in both operating manuals say 7 seconds; troubleshooting guide 506-00022A says below 102 VAC for more than 7 seconds and above 136 VAC for more than 8 seconds. CONFLICT (logged): both operating manuals (505-00152A and 505-00170A) and page 1 of troubleshooting guide 506-00022A give 102 / 136 VAC. Southwire's training manual lists the full-feature portables as Low (<102V) / High (>132V), and the error table on page 2 of 506-00022A prints the limits reversed ('lower voltage to >132V', 'raise voltage to <102V'). The suite uses the operating-manual figures, 102 / 136 VAC.
