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 T-Plus Software (optional) allows the operator to set all the programmable

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 and 24 Vdc OUT (see the following
figure).
