Lamp Test
Depress the <LAMP TEST> key on the controller’s front display
interface. All LEDs on the controller front panel, controller boards, and
Lucent serial rectifiers will turn on momentarily and then retire.
Alarm Test
Introduction Alarm Test provides a method of testing the operation of all or any of
the plant alarm relays and their wiring to the connected alarm system.
This test cannot be done if any alarms are active. It may also be desirable
to perform this test occasionally after the plant is in service to verify the
integrity of the office alarms for the power plant.
Alarm Test may be performed locally or from a remote terminal.
The Alarm Test feature will, in succession, operate each of the controller
alarm relays. With the basic controller, the default duration is one
minute. With the intelligent option for the controller, the selection of the
relays to be operated and default duration can be changed using the
EasyView interface.
Local Alarm Test Refer to Figures 2-1 and 2-2 for the SC Controller, and to Figures 2-3
and 2-4 for the SCF Controller.
SW202-5 on the BJB Basic Control Board must be enabled along with
its associated software switch found on the front panel under the path:
MAIN
→ CONFIG → ALARM → TEST ALM.
If HVSD is desired during the test, BJB SW202-4 must also be enabled,
along with the appropriate software switch found on the front panel
under the path: MAIN
→ CONFIG → ALARM → TEST HV. Each
rectifier in the plant must have a load of at least 10% of its capacity.
When configured with the optional intelligent controller, the alarm
conditions tested during Alarm Test and their duration may be specified
within EasyView with the path: MAIN
→ CONFIGURE → ALARM
TEST. As an alternative to the front panel configuration of the Alarm
Test software switch, it may be also configured within EasyView under
the path: CONFIGURE
→ DC PLANT → HARDWARE &
SOFTWARE CONFIGURED.
Note: Front panel LEDs do not activate during the alarm test. The
alarm relays whose contacts are accessed on TB2 and TB3 (BJT board
on rear of SC controller/BLG on top section of the SCF controller) may
be monitored to follow the progress of alarm testing.
