Panasonic SF4D Series Instruction Manual page 95

● Emitter indicator operation 1 when error occurs
When the device detects an error, the control output (OSSD 1 / 2) turns OFF and a number
blinks or lights yellow in the digital indicator.
● When an error is detected in the emitter, the emitter enters the lockout state. Light emission
stops, and thus the control output (OSSD 1 / 2) turns OFF.
● When an error is detected in the receiver, the receiver enters the lockout state and the con-
trol output (OSSD 1 / 2) turns OFF.
<Conditions: Line synchronization, Test input function invalid, Interlock function invalid>
Example: Series connection error ("2" blinks yellow)
