The set point output stays at 0 Vdc until the fre-quency becomes
higher than 505 Hz (that is 500 Hz + 1% of 500 Hz), then the output
goes at 24 Vdc and stays at 24 Vdc until the frequency be-comes
lower than 495 Hz (that is 500 Hz – 1% of 500 Hz).
It is possible to delay the set point checking for a programmable
delay time.
The PROGRAMMABLE SET POINT signal has the following default
settings:
The Navigator Software (optional) allows the operator to set all the
NOTE
programmable feature.
When no external input-output device is available this connector
must be closed with the supplied mating connector that short-circuits
the START and INTERLOCK inputs with the GROUND input (see the
following figure).
