723 governor

723 governor

723 governor

(OP)
Hello all,

I would like to know what would cause a 723 governor to open the generator breaker without any kind of indication at the control desk. This problem has occured on two separate occations and nothing was really found in the system.    

RE: 723 governor

Unless you have a custom programmed 723 they don't normally control the generator breaker. Unless the alarm and fault outputs are being used to trip the breaker.

Is this a stand alone or paralleled unit?  Island mode or parallel to grid?  What kind of load controls, DSLC maybe?

A few more system details would help.

The unit is parallel to the grid and the load control is DSLC.

RE: 723 governor

If your system is configured and wired like most DSLC over 723 systems, the DSLC breaker trip output is your likely culprit, not the 723, unless you have something not typical.  The DSLC trip output is normally closed, it usually only trips if the load/unload contact is opened and the load drops below the unload trip setpoint.

Is there a breaker trip wired to the 723?
