Set Up for Construction Operation
If required, it is possible to run the car during construction to help complete work in the hoist-
way. In this mode, the car runs at inspection speed. If they are in place, cartop controls may be
used or the car may be run from the controller or a temporary run box. (Refer to Temporary
Run Box on page 2-50.)
Minimal Requirements
Minimal equipment requirements are:
• The governor must be wired into the Safety string (SAFH).
• Car and counterweight must be roughly balanced.
Typically, the counterweight is sized to equal the weight of the car with 40%, 45%, or 50% of its
rated full load weight inside. At inspection speed, in the middle of the hoistway, with the car
properly loaded, drive current readings (F5, LF.93 or Magnetek D0/D2 MOTOR CURRENT)
should be equal in both up and down directions if counterweight/car balance is approximately
correct. A balancing procedure is provided in this section but, before you attempt to run the car
on Inspection, you must check that counterweighting has been addressed. Please refer to Car
and Counterweight Balance on page 3-8.
• If used, the temporary run box must be connected through the safety string. Please refer to
“Temporary Run Box Hookup.” on page 2-50.
• Motor, brake, and drive connected and set up.
• Velocity encoder or tach connected and functioning.
• Jumpers must be temporarily used to bypass absent equipment.
• The controller must be set to bypass faults on Inspection operation
Jumper Requirements
Temporary jumpers, as necessary, may be placed across the following connections if needed to
run the car on construction operation. If you are using a temporary run box, Please refer to
“Temporary Run Box” on page 2-50.
