4. SAFETY OBSERVATION FUNCTION
4 - 10
(c) Fixing-diagnosis at start-up
The input devices including the external wiring are diagnosed for failure by individually being turned
on and off repeatedly when the power is switched on. Enabled/disabled can be switched with [Pr.
PSD27] and [Pr. PSD28].
(d) Diagnosis with test pulses
The input devices including the external wiring are diagnosed for failure by using pulse signals that
temporarily turns off the input signals when the input signals are on. Enabled/disabled can be
selected with [Pr. PSD24] and [Pr. PSD25].
Set any test pulse width considering the wiring length of the external circuit, impedance of the circuit,
etc. If the pulse width is not enough, change the test pulse off-time with [Pr. PSD26 Input device -
Test pulse off time].
(e) Noise rejection filter
This function is to reduce the noise to input signals.
(2) Input device selection
(a) Input device selection
The input devices can be assigned to DI1_ to DI6_ with [Pr. PSD02 Input device selection DI1] to
[Pr. PSD07 Input device selection DI6].

(b) Input device automatic activation selection
Setting [Pr. PSD01 Input device automatic activation selection] activates operation command of each
function automatically. The automatically activated input device will be enabled regardless of input
device condition, and the corresponding function will operate automatically.
SLS1C (SLS1 command), SLS2C (SLS2 command), SLS3C (SLS3 command), and SLS4C (SLS4
command) can be automatically activated.
