Signal Lost (SST7100 only)
The signal lost function is defined as the absolute maximum allowable period (time between
input pulses in milliseconds) before an under speed relay is tripped. Similar to the Max Wave
Duration described in the previous step, the Signal Lost is necessary for low speed applications
where there is a programmed under speed trip. This setting should be set longer than the
period (in milliseconds) of the under speed setpoint.
