This selector is also referred to as the H-O-A switch. In the "Off" position power
will be removed from the motor in both bypass and drive modes of operation. It
should be noted that this will not cause AC input power to be removed from the
drive. To remove drive input power the Test/Isolate/Normal switch, If Provided
should be placed in the "Isolate" position.
In "Hand" mode, power will be applied to the motor from either the drive or the
AC line according to the Drive/Off/Bypass selector. In this mode the inverter's
frequency reference is determined by the position of the speed pot on the panel
if ordered.
In "Auto" mode, power will be applied to the motor only when a connection is
made between the two remote run contacts on the customer terminal board
inside the panel enclosure. In this mode the inverter's frequency reference is
determined by a customer supplied 0-10 VDC or 4-20 mA signal.
