Screen 1.1.1 is where you will determine if the PD100 will protect against abnormal
Overload only, Underload only, or both Overload and Underload. The default is
Both. If this is what you require, simply press the
button to accept and move onto
screen 1.1.2.
If you wish to select either Underload protection only or Overload protection only,
press either the
or
buttons to display the corresponding screen and then
press the
button to accept.
We will now enter the AutoSet margins. The margin is the % diff erence between the
‘normal’ motor load and where the trip point will be set. For example, if when the
AutoSet procedure is initiated, the normal operating load measured by the PD100 is
60%, and we have a Main Alarm Overload alarm margin of 20%, the trip point will be
set at 80% (60 + 20).
Note:
Depending on your setting for 1.1.1 you will see the following screens during the
next steps:
