TM 11-7021-202-12
Section Ill. OPERATION UNDER USUAL CONDITIONS
2-5.
INTRODUCTION
This section provides instructions for operating the processor under usual conditions. Should
equipment operating problems arise when attempting to use the processor, report the
malfunction on DA Form 2404 (DA PAM 738-750).
Do not operate equipment without a suitable
ground connection. Electrical defects in the
unit, test equipment, or load equipment can
cause DEATH by electrocution when contact is
made with an ungrounded system.
HIGH VOLTAGE is used in this equipment.
DEATH ON CONTACT may result if safety
precautions are not observed.
2-6.
INITIAL ADJUSTMENTS, DAILY CHECKS, AND SELF-TEST
Initial adjustments on the processor are beyond the scope of this manual. The Operator
performs the PMCS described in section II of this chapter on a newly installed processor
before operating. The BITE self-test runs automatically each time power is applied to the
processor as an initial operational checkout.
2-7.
OPERATING PROCEDURES
a.
Preliminary Procedures.
--
NOTE
The processor does not have a main power circuit
breaker. Power is applied to the processor as soon
as the power cable is connected to a power
source. The PWR ON/RESET indicator pushbutton
lights to indicate that power is supplied (para 2-3).
At power up, the CPU automatically performs the
BITE sequence of self-test diagnostics. The BITE/
BOOT indicator lights when the BITE tests have
been successfully completed. It takes about
15 seconds for BITE to run.
1.
Connect processor to prime power source. Verify that the PWR ON/RESET
indicator is lit. If the processor has semiconductor memory, verify that the BATT
indicator is also lit.
2.
Ensure that PMCS have been accomplished before operating the equipment (para 2-4).
