Machine Room Preparation

When preparing the machine room for elevator controller installation, consider:

• Equipment location

• Machine room environment
• Ethernet and internet access
Equipment Location
When choosing equipment location, consider:
• Adequate working space for comfort and efficiency.
• Logical arrangement, taking into consideration other equipment in the machine room and
routing of electrical power, control, and Local Area Network (10/100 Base TX) wiring.
• Do not install equipment in a hazardous location.
• Installing a telephone in the machine room is desirable as it makes remote diagnostics and
adjustment assistance more readily available.
• Wiring the machine room for internet access will allow MCE technical support to use the
iView application to remotely view system parameters, diagnose problems, and assist you
in adjusting elevator controller settings.
• If any areas in the machine room are subject to vibration, they should be avoided or rein-
forced to prevent equipment from being adversely affected.
• Provide adequate lighting for the control cabinets and machines. A good working space
such as a workbench or table should also be provided.

Environmental Considerations

• Ambient temperature should remain within 32
Temperatures outside these guidelines may be tolerated, but will shorten equipment life.
Adequate ventilation is required. Air conditioning may be necessary.
• The air in the machine room should be free of excessive dust, corrosive elements, and
excessive moisture. A NEMA 4 or NEMA 12 enclosure can help meet these requirements if
machine room conditions are inadequate. If the machine room has open or unglazed win-
dows or other direct outside openings, place equipment cabinets far enough from them so
that severe weather does not damage the equipment.
• Very high levels of radio frequency (RF) radiation from nearby sources should be avoided.
RFI may interfere with controller components, degrading elevator performance. Using
hand-held communication devices close to the controller may also cause interference.
Interference from permanently installed radio transmitting antennas is not common.
• Power line fluctuation should not be greater than ±10%.
