Flag Bits 2:
The flag bits present warning information. Flag Bits 2 is made from three digits as follows:
The first digit is made from two bits as follows:
1) Input Power greater than 30 Volts equals a value of 2.
2) Input Power less than 18 Volts equals a value of 1.
First Digit
Input Power
2
Greater than 30 VDC (Over voltage)
1
Less than 18 VDC (Under voltage)
0
Between 18 & 30 VDC (Acceptable)
The second digit is made from two bits as follows:
1) Tilt over current limit equals a value of 2 when the Tilt motor is overloaded.
2) Pan over current limit equals a value of 1 when the Pan motor is overloaded.

The third digit is made from two bits as follows:
1) Tilt Rate limit equals a value of 2 when the Tilt axis angular rate exceeds 25 degrees per
second.
2) Pan Rate limit equals a value of 1 when the Pan axis angular rate exceeds 25 degrees
per second.
