Interface Cable is connected to a Recorder USB FDAU Simulator (RUFS) to RI
Connector, P/N: 17TES0076. The operating power will be + 28 Vdc. The Cross−
over Cable Assembly is connected to the ROC/7 through the Ethernet port located
in the rear of the ROC/7.
B. Fault Condition Reset
In the event that the FA5000CVDR has an initial fault, or fails during the autotest, the
fault event will be recorded in the fault history log. The fault history log should be
displayed and printed before performing an initial or another return to service test on
the recorder.
Some faults may be “latched” faults (non-fatal) which can be cleared before perform-
ing the initial or another return to service test. If a latched fault does not clear, or the
autotest fails to return the expected results in the Status window, then dump the fault
history, reset the latched fault, if applicable, and attempt to re-run the test.
Test the recorder again after each corrective action taken. If the recorder fault is still
present, display and print the Fault History Log as described steps (1) − (14) in the
initialization procedure described in para. D.
NOTE
: To avoid producing an unintentional fault condition within
the recorder, the procedures contained herein must be
completely followed in the order presented, starting in para-
graph 2.C. of this section.
C. Power Check
(1) Connect the Recorder Interface Cable Assembly with FA5001 Adapter cable to
the rear connector of the FA5000 Recorder.
(2) DC (red lead = +28 Vdc, black lead = −28 Vdc) power source to the Recorder
Interface Cable Assembly DC power input pig-tail. (Caution:
Do not connect
both AC and DC simultaneously).
(3) At the Power source, while monitoring the wattmeter, apply supply voltage of
+28 Vdc to the Recorder.
(4) After 5 seconds, observe that the FA5000 is consuming no more than 12 watts
(True Power).
NOTE
: True Power is measured with a wattmeter. To obtain
True Power with a volt and current meter use the fol-
lowing formula: Vrms X Irms = Apparent Power.
Apparent Power X Power Factor (.58) = True Power .
(5) Turn OFF power to the FA5000 Recorder and wait at least 2 seconds.
