Menu 4.3.1 - Pre-Alarm Relay (R2) Latch
This menu relates to the
Pre-Alarm Relay Latch.
The factory default for the latch is
‘OFF’, which means that an alarm will cause the Pre-Alarm Relay (R1), to change state
while the alarm condition is present, but automatically default back to its normal state
when the motor load resumes a normal state. No Reset is required when the Relay
Latch is set to ‘OFF’.
To change the Latch to ‘ON’, fi rst press the
or
button. Now press the
or
buttons to change from ‘OFF’ to ‘ON’ and press the
button to accept the
change.
The screen will now show 4.3.2.
