9.6.1 Example of Use
A simple example of the logic will illustrate the principles of
programming a logic diagram. This example shows how to add
a "High Load Alarm" function to the FP-5000.
• Set the 50P-3 Phase IOC Alarm Pickup to 85% of the 51P TOC
Pickup setting. Go to "Set Mode" Protection ! Protection Setting
Group1 ! Alarms ! 50P-3 PH IOC Alarm ! Pickup and enter a
value of 0.85.
• Use programmable logic to turn on the Auxiliary LED and energize
Output Relay 4.
• Require the 50P-3 function pickup to be present for 1 second to
prevent spurious operation.
• Maintain the output signal for 5 seconds after the current drops
below the pickup level.
• Add an external switch to Contact Input 8 to enable or disable the
High Load Alarm at the user's discretion.
A Timer Gate has an On Delay and/or an Off Delay that can be set
for up to 9999 cycles (166 minutes at 60 Hz). Use 60 cycles for an
On Delay of 1 second and 300 cycles for an Off Delay of 5 seconds.
Figure 9-5 is an implementation of the "High Load Alarm."
The logic functions are programmed as follows from the main
settings menu:
