The direct and hardover mode&are still available when disabled.ENABLI:ACA operates normally.DIS .BL Removes 28-volt, 800-cps powerfrom the transducer primarycoils.THR CONT swAUTOLGC thrust commands are summedwith manual commands from theTTCA for DPS throttle control.Normally the TTCA is in theminimum position (10%) in thismode.

Without the engine arm signal neithereng1.ne will fire. The appropriate engine will be armed when the ABORTor ABORT STAGE B ltches are depressed, regardless of the position ofthis switch. l ,SAseThe ASe engine is armed.)

'.'C.,·A-5 'OFFThe arming signals are removed;therefore, this position can beused as a backup means to engineshutdown.DESThe DES engine is armed.X-TRANSL sw4 JETSProvides four jets for AGSX-axis translation maneuvers.2 JETSProvides two jets for AGSX-axis translation maneuvers.BAL CPL swThis switch, effective only with AGS, selects either balanced pairs ofx-axis RCS jets in a couple or unbalanced x-axis RCS jets for use inmaintaining pitch and roll attjtude during thrust phases.ONEnables the four up-firingjets for AGS controlled maneuvers.The switch should be in thisposition when maximum stabilization and control is required.OFFDisables the up-firing x-axisjets. The switch will be positioned to OFF to prevent RCSjet firings opposing the direction of motion during poweredphases - assuming adequate stability and control can be maintained by the down-firing jets.ENG GMBL sw"This switch enables or disables pitch and roll DPS gimbal trim commandsfrom the LGC or ATeA. The switch must be placed to ENABLE and the enginemust be armed to accomplish the trim function prior to and during a burn.If the ENG GMBL light illuminates during a burn and/or the RCS fuel eonf.umption is excessive the switch should be thrown to OFF.ENABLEoPitch and roll gimbal trimcommands are enabled.

A-6)Power is removed from theactuators and the gimbal malfunction logic is reset. Theactuators "lock up" in thelast commanded position.OFFDES ENG CMD OVRD swThe switch applies redundant power to the descent engine bi-propellantvalves to prevent inadvertent engine shutdown during a critical missionphase. During powered descent, the switch will be ON immediately afterignition and will r ain ON until after the landing. The circuit isinterrupted by the ABORT STAGE button and the engine STOP button.ONRedundant 28 vdc power isapplied to the descentengine valves.OFFRemoves 28 vdc from the biprop valves.LDG ANT swThe switch controls the position of the landing radar antenna.AUTOThe LGC automatically positionsthe LR antenna as a functionof mission phase.DESThe antenna x-axis is drivento a position 24 DEG from theLM body x-axis. The Y and Zantenna axes are 6 DEG fromthe respective body axes.This is the antenna positionduring the braking phase ofpowered descent.HOVERThe antenna x-axis is alignedwith the body x-axis and theY and Z axes are 6 DEG fromthe respective body axes.this is the antenna positionduring the approach and landingphases.,

If serves as the signal formanual engine shutdown prior to lunar impact. The light is blue and extinguishes when the STOP PB is depressed.T/W INDICATORThe indicator displays instantaneous x-axis acceleration in lunar g units.It provides a gross check on engine (APS/DPS) performance. " .

A-8)MASTER ALARM LIGHTSThe lights alert the flight crew to critical subsystem malfunctions.Upon receipt of the signal, the crew should reset the light and referto the caution a j warning panel. Depression of either switch willextinguish both lights and terminate the audible tone.ABORT PUSH BUTTON swThe switch should be actuated when an abort from powered descent, usingthe descent engine is desired. The switch activation arms the descentengine and signals the LGe and AEA to compute and execute the abort trajectory. The AGS will not issue automatic engine ON/OFF commands unlessthis switch is depressed. It is reset by depressing it a second time.ABORT STAGE PB swThe switch should be actuated when an abort staging sequence, with ascentengine ignition is desired. The switch activation will cause the following events to occur:1.The "Abort Stage" discrE'!te is sent to the LGC and AEA.2.The "Abort Stage" delay is initiated (500 ms).3.The DPS is shutdown.4.The APS is pressurized - should be completed in 400 ms.5.Power is transferred from descent to ascent batteries.6.At the termination of the delay, the selected guidance systemissues an engine ON command.7.A "stage" command is sent to the electro-explosive devices.If the Abort Stage sequence is initiated in coasting flight an ullage burnwill be required. This switch interrupts the redundant 28 vdc to the DPSengine valves. GINESTOP sw (2)The pushbutton switches separately interrupt the "ON" signal to the ascentand descent engines independent of the position of the ENG ARM switch.The STOP PB is the primary means of terminating thrust at lunar landingand should be used to back-up engine shutdown for automatic thrustingmaneuvers. When actuated the latching PB illuminates red and is reset)

The switch activation interrupts the redundant 28 vdcto the DPS engine valves.ENGINE START swThis PB momentary contact switch provides the crew with the capabilityto immediately fire the DPS or APS, depending on the position of theENG ARM sw. The START sw energizes a latching relay which provides acontinuous engine ON command and a RED light to indicate the relay isenergized. Activation of either STOP sw resets the latching relay,interrupts the ON signal and extinguishes the light.,r, ,ii X TRANSL sw(.\. :This PB switch applies 28 vdc to the secondary Res coils providing 4-jettranslation in X direction. It is the primary means of providing ullagefor manual APS/DPS burns. The switch is momentary contact and the signalis removed from the coils when the button is released. If the switchfails closed the ATT DIR CaNT cb must be opened DES RATE swThis switch can be used to control the rate of descent of the LM, ina semi-manual mode during powere.d descent. The vehicle must be underPGNS control in the attitude hold mode. Vehicle attitude is controlledby the crewman and the DPS throttle by the LGC. Each switch actuationprovides a discrete pulse, changing the rate of descent by 1 fps.Upward deflections of the switch decrease the descent rate and downwarddeflections increase it.B.oCONTROL MODES/SWITCHESGUlDCaNT.-sw,;.;,.MODECaNTsw-.'sATT CONT(selectable per.-ax is""")'--PGNSAUTOMODE CaNTR E.tfARKSThis is the switch configuration for all automatic PGNSmaneuvers.
