Error detection function
Input monitoring and grounding detection
When an error is detected at the inputs, the SG-ONE changes to the Protection state and displays
"1" on the error LED display. The conditions to be detected as an input error are shown below.
(1) When the input monitor error detection time (3s) is exceeded during the 2 input conditions and
they do not match (namely ON/OFF or OFF/ON).
(2) When there is an independent condition change of the 1 of the input.
(3) When the ON state of the input goes to the ground state.
The input LEDs blink and the monitoring output (Y
m
) send pulses (1Hz), to notify the operator of
the corresponding input. See Fig. 5-12
Noise detection filter
When the SG-ONE is used in an environment with severe noise, the SG-ONE changes to the
Stop state and displays "9" on the error LED display.
Note: Drive circuit corresponding to muting input (T
n
, T
n+1
) is always OFF.
