1–3Control Logic Wiring and Adapters
Publication 1336 IMPACT-6.2 – March 1998
The user inputs are connected to the L Option Board through TB3.
The L4, L5, and L6 options each have nine inputs: seven
user-configurable inputs and two factory-defined control inputs. The
function of each L Option must be selected through programming as
explained later in this section. The L7E, L8E, and L9E options are
similar to L4, L5, and L6 with the addition of encoder feedback L
Options.
L Option Board Jumpers
Important: If the L Option Board is being installed, Main Control
Board jumpers at pins 3 & 4 and 17 & 18 of J2 (J7 on
7.5 – 30 HP drives) must be removed. If these jumpers
are removed, they can be stored on the “spaces”
location on the Main Control Board. If this board is
removed, these jumpers must be reinstalled and the
L Option Mode parameter must be programmed to “1”.
