Load Profiles and Monitoring
Load monitoring allows the system to verify that the correct load is being lifted. If the load is out
of the allowable range, movement is stopped and an error message is displayed on the LCD.
In order to monitor the load, a load profile must be “learned” by the system. This is done by
loading the motor with the desired load and then allowing the system to learn that load. The
system can only learn one load at any given time.
There are two methods of recording a load profile: Full Profile and Quick Learn.
Quick Learn
In most cases the Quick Learn method can be used to record a new load for a lineset. The quick
learn method works for all attached loads that do not change weight during movement. A Quick
Learn simply records the static load at one position and the system adjusts any existing profile
to account for the change in static load.
To perform a quick learn:
Step 1:
Make sure the full static load is supported by the motor and is not resting on the
floor or scenery.
Step 2:
Insert a key into the “LOAD PROFILE” keyswitch.
Step 3:
Turn the keyswitch to [LEARN].
Step 4:
Press the select button for the motor you want to record a profile for.
Step 5:
Press the
[Trim]
button. The load is recorded immediately.
Step 6:
Turn the keyswitch back to [RUN].
Step 7:
Remove the key from the keyswitch or repeat for any other desired motors.
Full Profile
Full Profile learning records the load along the entire travel range of the motor. This allows
profiling for loads that vary based on position (such as stage electrics that gain or lose the
weight of power cables as they travel).
Recording a Full Profile involves running the motor from one limit to the other and back again.
Trims are ignored during the process.
To record Full Profiles:
Step 1:
Insert a key into the “LOAD PROFILE” keyswitch.
Step 2:
Turn the keyswitch to [LEARN].
Step 3:
Press the select button for the motor you want to record a profile for.
Step 4:
Press the [UP] or [DOWN] button to move the load to the nearest limit (upper or
lower). Do not release the button until the limit is reached. The load is not being
recorded yet.
Step 5:
Once the limit is reached, release the move button.
Step 6:
Press the opposite move button to move to the opposite limit. Do not release the
button until the new limit is reached. The load is now being recorded.
Step 7:
Once the new limit is reached, release the move button.
Step 8:
Press the original move button again to move to the original limit. Do not release
the button until the original limit is reached. The load is still being recorded.
