The set PROGRAMMABLE SET POINT Output voltage stays at 24 Vdc
until the frequency becomes higher than 505 Hz (that is 500 Hz + 1%
of 500 Hz), then the output goes at 0 Vdc and stays at 0 Vdc until the
frequency becomes lower than 495 Hz (that is 500 Hz – 1% of 500 Hz).
The PROGRAMMABLE SET POINT signal has the following default
settings:

reference quantity: frequency

threshold: 582 Hz

Threshold hysteresis: 2 %

activation type: high level active

delay time: 0 s
These settings can be changed by means of serial interfaces (see
“Windows Meaning” table, windows form 101 to 105). The same
settings are used by the SET POINT CONTACT OUTPUT.
SET POINT CONTACT OUTPUT : This output (relay contact) works
in the same way like THE PROGRAMMABLE SET POINT: it uses the
same settings used by this programmable set point.
In particular it is activated when the reference quantity chosen
(frequency, current, time, status normal) is higher than the threshold
setting value.
