a. Laser Module

(1) The Laser Module consists of:

Laser Cavity AssemblyQ-Switch AssemblyOutput Collimator TelescopePulse Forming Network (PFN)Fire SwitchMirror AssemblyHousing AssemblyMotor Driver AssemblyFlex Circuit, Laser ModuleBaseplate AssemblyElectrical Connector

(2) The Pulse Forming Network (PFN) receives high voltage from the Power Supply Module (in theElectronics Module) and charges the storage capacitor when the Charge Switch is pressed. The PFN uses acapacitor to store energy during the charge cycle. When the capacitor is fully charged, the Ready Indicatorilluminates. When the flashlamp trigger signal is given, a high voltage pulse is generated across theFlashlamp.

(3) When the Mode Switch (on the Electronics Module) is in the FIRST RTN or LAST RTN position andthe Ready indicator is visible, the signal from the Fire Switch commands the Range Counter Module (in theOptics Module) to provide a Q-motor start signal. This start signal is connected to the Motor DriverAssembly to start the Q-Switch motor. When the motor reaches the proper speed and position, a flashlamptrigger signal is produced that discharges the stored energy of the capacitor in the PFN through the Flashlamp.Part of the laser beam output, used as an initiating pulse designated T. is shunted to the Prism ClusterAssembly (in the Optics Module).

(4) When the Flashlamp triggers, it “pumps” the laser rod and the laser fires. The Laser, consisting ofthe flashlamp, laser rod Q-switch assembly and partial mirror assembly, produces an output beam. This beamtravels through the Output Collimating Telescope, which is made up of a comer cube prism, telescopeobjective lenses, and the (visible light filter) output window.

b. Optics Module

(1) The Optics Module consists of:

Range Counter ModulePrism Cluster AssemblyEyepiece AssemblyObjective Lens AssemblyReceiver ModuleReticle LEDFlex Circuit Assembly, Optics ModuleHousing Assembly, Optics ModuleElectrical Connector (2 ea)Test Connector

1-6

TM 11-5860-202-23&P

(2) The Optics Module receives visible light and the reflected laser energy from the target into the ObjectiveLens Assembly. The Objective Lens Assembly focuses the incoming visible light and reflected laser energy onthe Prism Cluster Assembly.

(3) At the Prism Cluster Assembly, the laser energy is diverted to the Receiver Module which provides asignal to the Range Counter Module to stop timing and convert the time into a distance for display in theEyepiece Assembly.

(4) The visible light is directed to the Eyepiece Assembly with the Reticle imposed over the target image.The Reticle, attached directly to the Prism Cluster Assembly, can be illuminated by pressing the ChargeSwitch, pulling the Reticle Control (on the Electronics Module) and rotating the control to obtain the desiredillumination. The reticle illumination will be automatically cutoff after 8 seconds.

(5) When the laser fires, the To pulse, received from the Laser Module, is used by the Receiver Module tosignal the Range Counter Module to reset and start the timing circuits.

(6) The Range Counter Module will provide a Q-motor start signal to the Laser Module when the FireSwitch (on the Laser Module) is pressed. If the Mode Switch position on the Electronics Module is FIRSTRTN, the Range Counter Module will stop with the first return signal. If the position is LAST RTN, the RangeCounter Module will display the value of the last return signal.

(7) The display for range is mounted on the Range Counter Module in such a way as to be in the focal planeof the Eyepiece Assembly and will be observed at the bottom of the view in the Eyepiece Assembly. The RangeCounter Module display is four digits corresponding to meters, with the last digit displayed as a zero or fiveonly. A Ready indicator, to the left of the range digits, will be illuminated when the charge cycle is complete anduntil a Fire signal is given or eight seconds have elapsed. If a range is not taken within eight seconds after aCharge command, the unit will power down. A Low Battery condition is indicated by the display flashing allzeroes after the Charge Switch is pressed and until the Fire Switch is pressed. When the range value isdisplayed, the flashing stops. If more than one return signal is sensed by the Receiver Module during the timingcycle, a Multiple Target Indicator is illuminated to the right of the range digits in the display.

(8) The Test Connector is used during repair. Two test points at the Test Connector are accessed. Theready test point is from the high voltage circuit and indicates a ready status as 5 Vdc. The reticle test point is the5 Vdc to the reticle illuminating LED. This test point should be approximately 5 Vdc until the Reticle Controlis pulled, at which time the voltage should drop to less than 2 Vdc.

c. Compass/Vertical Angle Measurement Module

(1) The C/VAM Module consists of:

C/VAM Mode SwitchC/VAM Module HousingDeclination Angle Adjust pushbuttons

(2) The C/VAM Mode switch has four positons: C/VAM, ZERO, DEC, and OFF. C/VAM contains thecircuitry to provide target azimuth and vertical angle displays. The azimuth and vertical angle display, as well asthe range display, are controlled by the Charge and Fire switches located on the Electronic Module and LaserModule. DEC. ADJ. pushbuttons allow for the correct selection of roils or degrees display and for correct

magnetic declination angles, when known, to be entered into the system. Vertical angle and azimuth sensors arecontained in the C/VAM module while the 24 VDC power for the module is applied through the Mode Switchfrom the Power Supply module in the Electronics Module.

d. Electronics Module

(1) The Electronics Module consists of:

Power Supply Module Housing, Electronics Module Flex Circuit, Electronics Module Charge Switch Mode Switch

Reticle Control Electrical Connector

(2) The Power Supply Module, depending on the position of the Mode Switch, supplies:

5 Vdc to the specified circuits in the Optics and Laser Modules. The 5 Vdc circuit is a precision voltageregulator using a monolithic switching regulator integrated circuit to obtain a positive 5 Vdc output.

12 Vdc to the Receiver Module circuits in the Optics Module. The 12 Vdc circuit is a precision voltageregulator using a monolithic switching regulator integrated circuit to obtain a regulated +12 Vdc output. The12 Vdc circuit is a separate circuit from the 5 Vdc circuit.

Switched 24 Vdc, battery voltage, to power the Q-motot in the Laser Module when the Charge Switch ispressed and a Q-motor start signal-is given when the Fire Switch is pressed.

High Voltage for the Laser Module. The High Voltage output is produced from a flyback DC-to-DC convertercircuit. The output is between 700 to 850 Vdc, adjusted by by a potentiometer located in the Laser Module. Thepotentiometer is used to determine the voltage level of the energy storage capacitor. The High Voltagecircuit is held off until the Charge Switch is pressed. When the circu it reaches the regulation level, a Readysignal is sent to the Range Counter Module to illuminate the Ready Indicator in the Display.

(3) The Mode Switch connects battery power to the Power Supply Module circuits. The Mode Switch hasfour positions: OFF, FIRST RTN. LAST RTN, TEST (PULL). OFF disconnects battery power from all circuitsexcept the compass connector. FIRST RTN connects battery to all circuits (after the Charge Switch is pressed)and to the range counter to stop timing at the first return pulse, LAST RTN comects power to all circuits (afterthe Charge Switch is pressed) and will permit the timing to complete the full cycle and then display the value forthe last return pulse, TEST (PULL) connects power to illuminate all elements and indicators in the dispkiy (afterthe Charge Switch is pressed).

(4) With the Mode Switch in FIRST RTN or LAST RTN, the Charge Switch will initiate the charging ofthe PFN capacitor (in the Laser Module) and, when the capacitor reaches the set voltage level, the Readyindicator will illuminate in the display to the left of the range digits.

(5) With the Mode Switch in any position except OFF. The Reticle Control will illuminate the Reticle inthe Optics Module’s eyepiece display when the Charge Switch is pressed.

6. How to Locate Repair Parts

a. When National Stock Number or Part Number is Not Known.

(1) (First). Using the table of contents, determine the assembly group or subassembly group to which theitem belongs. This is necessary since figures are prepared for assembly groups and subassembly groups,and listings are divided into the same groups.

(2) (Second). Find the figure covering the assembly group or subassembly group to which the itembelongs.

(3) (Third). Identify the item on the figure and note item number.

(4) (Fourth). Refer to the Repair Parts List for the figure to find the part number for the item numbernoted on the figure.

(5) (Fifth). Refer to the Part Number Index to find the NSN, if assigned.

b. When National Stock Number or Part Number is Known:

(1) (First). Using the Index of National Stock Numbers and Part Numbers, find the pertinent NationalStock Number or Part Number. The NSN index is in National Item Identification Number (NIIN) sequence(see 4a). The part numbers in the Part Number index are listed in ascending alphanumeric sequence (see4.b). Both indexes cross-reference you to the illustration figure and item number of the item you arelooking for.

(2) (Second). After finding the figure and item number, verify that the item is the one you’re looking for,then locate the item number in the repair parts list for the figure.
