Setup and Adjustments
This section describes how to set up the
VFD66 control. Remove the terminal access cover to
access the jumper blocks and internal potentiometers.
See

!
WARNING: Risk of Electric Shock.
Disconnect power from the control before making
any adjustments. Do not touch any part of the
printed circuit board while power is applied. Failure
to follow these precautions can result in personal
injury or death.
Control settings are established by positioning
six jumpers and adjusting two potentiometers.
Factory default settings have all the jumpers in the
installed position and the potentiometers set fully
clockwise. (See Table 4, Figure 3 and Figure 9.)

1. Do not discard jumpers. See Figure 9.
To place a jumper in the removed position, reposition
the jumper so that it is connected to only one pin on
the jumper block. Keep the jumper because it may be
needed in the future. To place a jumper in the installed
position, place the jumper on both pins (Figure 9).
Jumper blocks J2 and J3 establish input modes and
work in conjunction with potentiometers P1 and P2.
See
Selecting an Input Mode.

Figure 9: Jumper Placement on Pins
Jumper blocks J5 and J6 have jumpers installed on
the two middle pins of each jumper block. These
jumpers activate the internal potentiometers. Moving
the jumpers from the factory-installed position disables
the internal potentiometers.
