Emerson SERIES 600T User Manual

The VIB provides fully isolated inputs and outputs that operate on a wide range of voltages for maxi-

mum flexibility. Each I/O is programmed to perform a dedicated function. The specific function of 

each I/O is listed below in Table 34.

For reference, the I/O designations are shown in Figure 117. The number of each I/O is also labeled 

on the circuit board.

1. The “OFF” signal is also used to indicate if the temperature of the rotor is too warm. If the “OFF” output is asserted while any 

of the other “Mode” outputs are asserted (STARTUP, CHARGE, SHUTDOWN, DISCHARGE) or while the State of Charge is 
>= 0%, then the rotor is too warm and must cool before charge resumes.

2. “START” and “SHUTDOWN” inputs are mutually exclusive. If they are asserted simultaneously, both will be ignored.
