Testing
Overview
This section provides test procedures for newly installed and/or
operating rectifiers. If the plant in which a rectifier is being installed has
never been operational, the plant and controller tests must be performed
before the rectifier tests. Consult the plant and controller product
manuals for their installation test procedures.
Rectifiers can be tested on- or off-line. “On-line” means a battery string
and/or office load is connected to the rectifier. A dummy test load is
required for testing off-line, and a Battery Plant Simulator Test Set is
desirable. Without a simulator, a minimum set of tests can be
performed. See “Battery Plant Simulator Test Set” for a description of
the simulator and test load. For troubleshooting and diagnostic
procedures, refer to Section 7. Those unfamiliar with the function of
rectifier controls and indicators should read Section 2.
Precautions
When working on power systems, observe safety precautions in Section
4 and those within each procedure.
•
The ac input voltage powers certain control circuits and relays, the
front panel LEDs except ac fail, and the ac contactor. Voltage is
available to these circuits whenever the ac service is available to the
rectifier.
•
Remote sensing of rectifier output occurs via the plant control cable
connected to P5A or TB1 and TB2 on CM4. This cable must be
disconnected when internal sensing is desired, as when testing off
line using a test load.
Warning: Do not turn the CB1 circuit breaker ON, close an external
charge circuit breaker, or install an external charge fuse until told
to do so.
