Technical Information
For example:
reference quantity: frequency

threshold: 500 Hz

hysteresis: 1%

activation type: "high level"

Figure 85
The set point output stays at 0 Vdc until the frequency 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:
reference quantity: frequency

threshold: 909 Hz

hysteresis: 2 %

activation type: high level

delay time: 0 second.

The TwisTorr 305-ICQ & 305-IC SF Software (optional) allows the operator to set

all the programmable feature.
