Introduction and Product Description

!
ATTENTION: Certain procedures in this manual require that
the drive “Not be running”. This assumes that the DC loop
contactor is de-energized and that the user has properly set up
the interface logic to meet this criteria.
Additional hardware allows for a separate discrete input to the Drive. The
input device (Pushbutton, selector switch, etc) is connected to terminal
block J5 and is jumper selectable (see table 2–A) for either a 115V AC or
24V DC input. The function and operation of this input is controlled by
parameter settings.
LED Indicators
The MCA board contains several LED’s used to provide status
information. LED DS1 indicates wheter the MCA board itself is faulted or
not faulted. LED’s DS2 and DS3 duplicate the function provided by the
LED’s on the Interface Plug. LED DS4 indicates the status of the Discrete
input. Tables 2–A and 2–B provide information on LED’s DS1 – DS4.

Firmware Location
The MCA Board contains a microprocessor (U20) which is responsible for
controlling all board functions and features. This board contains firmware
version 1.xx (the “xx” designator may vary but does not affect information
in this manual). Figure 2–1 shows the physical location of the firmware
chip (UMA1). The setup and configuration data for the Adapter board is
stored in the EEPROM memory located on the main control board of the
Drive.
