MCE SmarTRAQ - Learning Open;Close Positions; Establishing Door Close Limit (DCL)

Adjustment
17
Learning Full Open and Full Close Positions
The operator learns open and close limits when current rises to preset limits (C1 open, C3 close)
when doors reach full open or full close. Once limits are learned, SmarTraq is able to distinguish
between an obstruction and full open or close positions. DOL (Door Open Limit) and DCL
(Door Close Limit) can be learned only in the last 1/2” (13 mm) of door travel in either direction.
• Doors Full Open: Door Open Limit is energized and programmer board DOL LED lights
• Doors Full Closed: Door Close Limit is energized and programmer board DCL LED lights
Establishing DCL
One of the parameters programmed into the drive is C3, closing torque. In order to establish the
Door Close Limit, the operator must close the doors and continue applying closing torque until
the C3 value is achieved. At that point, the DCL LED on the programmer board will light and
the programmer display will “say” Lr. Once Lr is displayed, you are able to cycle through and
change parameter values, even before performing a “door learn” operation.
1. Verify that elevator doors are closed.
2. Place Local/Remote switch in the Local position.
3. Turn power ON.
For a few seconds, dashes will be displayed on the LED display. Then, the dash on the
right hand display will disappear. The inverter drive is ready to accept input.
4. Hold the Open/Close switch in the Close position. The doors will close. The DCL LED
will light and Lr will be displayed. The motor may cog to establish DCL. (The doors may
actually move open slightly before closing because the operator does not “know” its
position yet.)
If DCL is not Established: Occasionally, torque settings or door weights are such that
DCL cannot be established. If so, the programmer will instead display C3 (the closing torque
parameter). If this occurs:
1. With “C3” displayed, press ENTER. The present C3 value will be displayed.
2. Use the “-” (minus) button to reduce the value by two counts. (For example from 10 to
8.)
3. Press ENTER to enter the new value.
4. Press the “+” or “-” button to display “do.”
5. Press Enter to save changes to memory.
6. Put the Local/Remote switch in the Local position.
7. Hold the Open/Close switch in the Close position until the programmer displays “Lr.”
“Lr” indicates that the DCL has been learned and the door operator is ready for you to adjust
remaining parameters. If “Lr” does not appear, repeat the seven steps above to reduce C3 value
and again close the doors to learn DCL.
