Technical Information
Interconnections
The voltage is provided between pins 14 and 15. An high impedance
input should be connected to this output (> 100 kΩ).
FAULT: this relay output signal is closed when any system fault
condition is detected. To detect the type of failure the serial protocol
is needed (see the para. "RS232-485 Comunication Description").
SET POINT: this relay output signal is enabled when the reference
quantity chosen (frequency, current or time) is higher than the set
threshold. The signal can be "active close", or "active open". 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.
