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

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.

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.

Ensure that PMCS have been accomplished before operating the equipment (para 2-4).
