4. SAFETY OBSERVATION FUNCTION
(a) Executing fixing-diagnosis at start-up
This function diagnoses a fixing by turning each of DI1_ to DI6_ on, off and on one by one. When all
diagnoses are completed, a warning will be reset, and STO state will be canceled. Keep the pins not
to be diagnosed to on.
The following pins are diagnosed: pins to which functions are assigned with [Pr. PSD02 Input device
selection DI1] to [Pr. PSD07 Input device selection DI6], and in which [Pr. PSD27 Input device -
Fixing-diagnosis execution selection 1 at start-up] and [Pr. PSD28 Input device - Fixing-diagnosis
execution selection 2 at start-up] are set to "execute".
Additionally, the diagnosis will not be executed to the pin (unused pin) to which an input device is not
assigned with [Pr. PSD02 Input device selection DI1] to [Pr. PSD07 Input device selection DI6].
