Frequently Asked Questions about 489-P5-HI-A20

What does the A20 stand for in the part number 489-P5-HI-A20 GE generator management relay?
The A20 stands for the analog outputs, in this case the A20 indicates 4 to 20 mA analog outputs. 
What will indicate a trip in the 489-P5-HI-A20 GE generator management relay?
A trip feature by a 489-P5-HI-A20 GE generator management relay may be assoicated with a combination of any of the four output relays. The appropriate LED indicator on the 489-P5-HI-A20 when a trip is active, the faceplate lights up to tell which output relay has been operated.
Is there a passcode for setting up the 489-P5-HI-A20 relay?
Yes, there is a password when setting up the 489-P5-HI-A20 GE generator management relay. The default passcode is set at "0". Also the protection of the password is protected when the passcode is set at 0.
