FAULT: this open collector output signal is ON when a system fault
condition is detected.
PROGRAMMABLE SET POINT: this open collector output signal is
enabled when the reference quantity chosen (frequency, current or
time) is higher than the set threshold. The signal can be "high level
active" (that is the output is normally at 0 Vdc and becomes 24 Vdc
when activated), or "low level active" (that is the output is normally
at 24 Vdc and becomes 0 Vdc when activated). Moreover, if the
reference quantity is the frequency or the current drawn, it is
possible to set the hysteresis (in % of the threshold value) to avoid
bouncing.
For example:
220/258
reference quantity: frequency
threshold: 500 Hz
hysteresis: 1 %
actiation type: "high level"
