PD Card Operation

• Reduced Load Hot

• Full Load Cold
Like the basic Time-Based Trigger, the Operating Point Trigger intervals will be set to 14
days if the machine’s voltage rating is 6 kV or less, or to 30 days if the machine’s voltage
rating is greater than 6 kV.

A measurement saved in the Archive due to an Operating Point Based Trigger will appear
in PDView with a flag indicating the specific operating point:

• A “FLH” flag indicates a Full Load Hot Trigger
• A “FLC” flag indicates a Full Load Cold Trigger
• A “RLH” flag indicates a Reduced Load Hot Trigger.

Like the Time-Based Triggers, in the case of an Operating Point Time-Based Trigger, each
measurement in the set will have the same Trigger indication

Figure 4-2 Example of an Operating Point Based Trigger in PDView
NOTE:
Operating point Triggers will not occur unless the monitor can acquire the
machine’s active power and asset temperature Operating Conditions
either through a Remote I/O Unit or directly through Modbus. This
configuration is done using IAM; refer to Section 6.3.

4.6.5. Level-Based Triggers
These Triggers detect Qm levels on the input pairs and resolve down to a combination of
input pair, sensor and polarity. This means that a Qm level detected on input Phase A
Machine positive PD causes a different Trigger than a Qm level detected on input Phase A
Machine negative PD; each combination of input, sensor and polarity has its own Trigger.
There are three different Qm thresholds used for the Level-Based Triggers.

• Moderate
• High

• Very High
The Trigger interval for each of these is 30 days; additionally, the Trigger must be
confirmed over multiple measurement cycles before the Trigger actually occurs.
