Inspection Details
In normal environments, inspect the NT631/NT631C at intervals of between 6
months and a year. In environments that are extremely hot and humid, or very
dusty environments, shorten the inspection interval.
Items Required for The Inspection
Prepare the following items before starting the inspection.
Points Inspected
Inspect the following points to determine if there is any divergence from the
stated criteria. If there is, either improve the surrounding environment so that
the values fall within the stated range, or adjust the NT631/NT631C, for exam-
ple by re-tightening screws.
1. Do not disassemble for repairs or modification.
• Screwdrivers (Phillips, flat head)
• Tester (or digital voltmeter)
• Industrial alcohol
• 100% cotton cloth
• Hygrometer (required in some cases)
• Thermometer (required in some cases)
• Synchroscope (required in some cases)
• Pen-writing oscilloscope (required in some cases)
Permissible voltage fluctuation range
20.4 to 26.4 VDC (24 VDC –15% to
+10%)
0 to 50°C
35% to 85% RH
