Overview
This part of the manual explains how to learn the hoistway and adjust the car.
Learning the hoistway is the operation where the controller runs the car from
the bottom to the top of the hoistway, recording the location of switches and
door zone magnets it sees along the way. Once the hoistway is learned, the
controller can run on automatic operation and adjustments to the ride and
performance can be made.
Pre-Check
A. Does the car move? If not check the Safety String and for correct Door
Limit and Hall Lock signals.
B. Do the DZ magnets register on the selector when passed over?
C. Is leveling speed < 20 FPM in both directions?
D. On the machine room SRU: does 509/510 go out when at top floor DZ
and 511/512 go out when at the bottom floor DZ?
E. On the LCD screen: when the car moves up is FPM positive and when
moving down is FPM negative?
Procedure
On the Machine Room SRU board put the controller in Learn mode by flipping
DIP Switch #2 (on Dip A) to the right (ON) position. Inspection takes priority over
Learn so be sure all the Inspection/Hoistway Access switches in the machine
room, cartop, and in the car are in the Normal (automatic) position.
The LCD should now show “Learn” on the Home Screen. This indicates the
controller is ready to learn the hoistway. If it still shows “Inspection” then you
need to check to see which inspection input(S) are not powered and jump them
to 24vdc.
A. “Inspection (MR)” machine room inspection.
B. “Inspection (CT)” Cartop Inspection inputs.
C. “Inspection (HA)” Hoistway Access inputs.
D. “Inspection (IC)” In-Car inspection inputs.
There are three main steps involved in learning the hoistway. They are all
performed from the MAIN MENU | SETUP | LEARN MODE COMMANDS menu
of the machine room SRU (this option is only available on the Machine Room
SRU).
