Machine Room Construction Run
Before running on Construction mode, certain equipment must be in place:
• Final limit switches. These switches are wired into the safety string and will immediately
drop power to the machine and brake when opened.
• Pit Stop Switch (Safety string should be as complete as possible)
• Fully functional governor and car safeties
• The governor overspeed switch must be wired between SCE-UPD screw terminals GOS1
and GOS2.
• Pit buffers
• Temporary run box (if cartop inspection run is to be used)
• Traction car and counterweight must be roughly balanced per anticipated loading.
• Place both Car Door and Hoistway Door switches in the BYPASS position.
The SAFC input on the SCE-HVI board must see 110VAC before the car can run. If you have a
minimal safety string connected as shown in the job prints and as referenced above, this
requirement will be met. See figure below.
Before the landing system is installed and the hoistway is learned, the car will be unable to run
on construction mode due to faults generated by the lack of this equipment. To bypass faults on
construction mode:
• On the SCE-CPU board, move the FLT BYPASS jumper to BYPASS. This bypasses control-
ler response to faults (except Overspeed) during Inspection operation. Inspection mode
fault bypass remains active, even across power cycles, until set to NORM.
• Go to the Utilities menu on the touch screen (UTILS), select Construct and Bypass Faults.
• Press Construction/Fault Bypass Disabled button to set it to Enabled.
