Test elevator car leveling devices for landing accuracy of plus or minus 6 mm 1/4 inch at each floor with no
load in car, symmetrical load in car, and with rated load in car in both directions of travel. Determine accuracy
of floor landing both before and immediately after endurance tests. [For Class C2 landing, comply with ASME A17.1
Section 2.16.2.2.4 for freight elevators. Do not exceed the maximum load of 150 percent of rated load on car
platform during loading or unloading.]
3.2.2.5 Pressure Tests
Check operating pressure at pump and cylinder head under no load and rated load. Test pressure at which relief
valve operates.
3.2.2.6 Insulation Resistance Tests
Perform tests to ensure wiring systems free from short circuits and grounds. Minimum acceptable insulation resistance
for electrical conductors is one megohm between each conductor and ground and between each conductor and other
conductors. Prior to megohm meter test, make provision to prevent damage to the electronic devices.
3.2.2.7 Temperature Rise Tests
Determine the temperature rise of the hydraulic pump motor during the full load test run for a minimum of one
hour. Under these conditions, do not exceed maximum acceptable temperature rise indicated on the manufacturer's
data plate. Start test only when equipment is within 5 degrees C of ambient temperature.
3.2.2.8 Motor Ampere Tests
Measure and record motor amperage when motor is running and elevator is lifting at rated load and speed. Measure
and record motor amperage at the beginning and the end of Endurance test.
3.3 OPERATION AND MAINTENANCE TRAINING
The Elevator Specialist shall instruct Government personnel in care, adjustment, and maintenance of elevator
equipment for a period of not less than [5] [_____] working days immediately following acceptance of system.
Submit Operation and Maintenance Manuals as required in the Submittals paragraph.
