Important Note:
Whereas Relays 1 and 2 are related
to abnormal ‘process’ conditions, such as pump run
dry and conveyor jams, the General Alarm Relay (R3),
is associated with abnormal conditions such as Over
Voltage, Under Voltage, phase asymmetry and locked
rotor.

Menu 5.1.1 - General Alarm Relay (R3) function
In Menu 5.1.1 we will configure whether we want the General Alarm Relay to activate
on Over Voltage, Under Voltage, or both Over- and Under Voltage conditions.
Press the
or
button to display the protection that you require and then press
the
button to save your programmed parameter. The word ‘SAVED’ will appear
for two-seconds and the screen will proceed to 5.1.2..
For the PD100, Menu 5.1.2 will display ‘VOLT’ which cannot be changed. Press the
button, which will take you to either 5.1.3 if you selected ‘OVER’ or ‘BOTH’ in
Menu 5.1.1, or to Menu 5.1.4 if you have set Menu 5.1.1 to ‘UNDER’.

Menus 5.1.3 and 5.1.4 - General Alarm Relay (R3) Over Voltage and
Under Voltage trip points
In both 5.1.3 and 5.1.4 you will set the % deviation from the normal motor supply
that was programmed in Menu 2.8.0. The deviation % can be set at different values
for Over Voltage and Under Voltage. For example, you may want to PD100 to provide
a General Alarm at 10% Over Voltage and 15% Under Voltage. Remember, these
percentages relate to what you programmed in Menu 2.8.0. For example, if 2.8.0 was
set to 480V and you set 10% in 5.1.3, then your Over Voltage alarm will activate at 480
+ 10% = 528V.
To set these values, follow the same procedure that was used when programming 2.8.0.
When complete, press the
button to proceed to Menu 5.2.0.
