password. These are indicated by and (S) following their descriptor. Other values have the indication (U)
following their descriptor. These values may be adjusted by an operator logged in with the User level username
and password. If an operator is not logged in, touching a numeric entry field will pop up the user name and
password entry fields. To enter the user name, touch the user name field; an alphanumeric keypad will appear.
Use this to key in the appropriate user name, then press the ENTER key on the keypad. Follow the same

User-level privileges permit changes to the following items, indicated by a (U) following their descriptors:
LD WNDW: Load window (pounds). The acceptable variance from moment to moment during movement –
initially should be set to 10
to eliminate false tripping.
LOAD MAX: Maximum load (pounds). The largest load imposed on the system during load learning, inclu
acceleration and deceleration loads, cable weight pickup, etc. May be manually adjusted after load learning.
LOAD MIN: Minimum load (pounds). The smallest load imposed on the system during load learning, includ
acceleration and deceleration loads, cable weight transfer, etc. May be manually adjusted after load learning.
LOAD SENSING ON/OFF: User level password privileges are required to turn load sensing on or off for a winch.
System-level privileges are required to change system parameters. These are indicated by the letter (S) following
their descriptors. If an operator is not logged in, or is logged in with user-level privileges, touching a numeric entry
field for a system parameter will pop up the user name and password entry fields. Once the operator is logged in

The load sensing parameters may be automatically calculated for a winch by following the load learning
procedure. First the batten should be loaded as it will be during operation. Next, navigate to the load sensing
parameters page, and touch the LOAD LEARN touchbutton to turn Load Learning ON. Return to the winch base
screen and run the winch up and down near the ends of its travel at various speeds; be sure to include the
greatest speed and shortest accel/decal times that will be required under operation. Finally, return to the load
sensing parameters page and use the LOAD LEARN touchbutton to turn load learning OFF. Verify that the
values now entered in the Load Window, Load Max and Load Min fields, then use the LOAD SENSING
touchbutton to turn load sensing on. Return to the winch base page and run the winch again, to verify that the
