Instructions for the FP-6000 Protective Relay
Table 54. Logic Input Group Definitions.
Note:
All inputs can be negated from the front panel. An exclamation
mark, “!”, indicates the input is negated.
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-6000.
•
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 Programmable LED 8
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 75 is an implementation of the “High Load
Alarm.”
