1.2. DESCRIPTION AND DATA 1.2.1. DESCRIPTION A. Purpose The PS-40 is an effective night vision system that mounts forward of an existing riflescope/spotting scope (further referred to as a scope) adding night vision capabilities to daytime target acqui- sition platform. Advisable dayscope magnification is 1X to 12X (2.5X to 8X is optimum).
• Is submersible to 10 m for 30 minutes. • Filled with dry nitrogen to prevent internal fogging. The PS-40 is an effective night vision system designed for night operations but does have following limitations: • The sight requires some night light (moonlight, starlight, etc.) to operate.

2.1. INSTALLATION PROCEDURES 2.1.1. BATTERY INSTALLATION CAUTION Ensure the function switch is in the off position before installing a battery. Install the battery as follows: 1. observe Figure 2-1 for right position of the threaded insert ac- cording to the battery to be installed. 2.
Measure the height of the riflescope axis above the rail. Observe Table 1-2 for the sight axis height above the rail. If the difference in the axis heights of the PS-40 and riflescope is more than 3 mm it is necessary to replace riflescope mounting rings or monoblock by proper ones.
2.1.3. INSTALLATION ON DAYSCOPE OBjECTIVE LENS Presented in Table 2-1 optional scope mounting systems are de- signed to install the PS-40 on riflescope/sporting scope objective lens. The systems are equipped with a rail for mounting optional Ir illuminator. TABLE 2-1. SCOPE MOUNTING SYSTEMS...
To choose the system # and insert refer to the Table 2-1. For example, the scope mounting system #1 and 47 mm insert are necessary to mount the PS-40 on leupold 3.5-10x40 riflescope. NOTE Optical axes of the PS-40 and the riflescope should be matched.
M4x8 and tighten it. 5. loosen the nut of the mounting system. 6. Slide the PS-40 with mounting system onto the objective lens of dayscope up to the stop. 7. To complete the installation of the mounting system to your day- scope, use a screw driver to tighten the nut of the mounting sys- tem.
2.2. OPERATING PROCEDURES 2.2.1. GENERAL This section contains instructions for placing the PS-40 into opera- tion. The function of controls is explained. CAUTION The PS-40 is a precision electro-optical instrument and must be handled carefully at all times. 2.2.2. CONTROLS AND INDICATORS...
2.2.3. OPERATING PROCEDURES These procedures should be performed under night light condi- tions only. CAUTION Use of the PS-40 under high light conditions may damage the image intensifier. 1. Make sure the battery is installed as indicated on the sight body.
CAUTION Bright sources such as light of fire, headlights, searchlights, etc. can damage the PS-40. Avoid exposing the PS-40 to these types light sources. 6. Adjust image tube brightness using the gain control knob (MGC version of the sight) to achieve the best possible image contrast.
2.2.4. OPERATING AT CHANGING LIGHT CONDITIONS The sight has a protection system, which cuts off the image inten- sifier when ambient light level exceeds the limit of 40 lux during 10 seconds. If a mission has to be carrying out at changing light conditions, it is possible to shut down the protection system with the following procedure: take off the rubber cap from remote switch connector and put it onto the light sensor.
2.2.6. STOwAGE OF PS-40 1. ensure the PS-40 and all accessories are clean and dry before returning to storage case. 2. replace the objective cap and output cap on the lenses. re- move the battery. 3. Make sure the sight and accessories are stored in the appropri- ate locations in the case and close the cover.
2.3. INSTALLATION AND USE OF ACCESSORIES 2.3.1. 7/8” wEAVER MOUNT optional Weaver mount can be used to install the PS-40 on a MIl- STD-1913 rail if mounting rail on the rifle has narrow groves (4 mm). WeAver MoUNT M4X8 SCreW ClAMP BAr FIGURE 2-10.
PS-40 in short-time activation mode. Attach the remote control to the PS-40 and use it as follows: 1. remove the rubber cap from the connector. The rubber cap can be placed onto the screw head, that attached the strap of cap to the body of device (see Figure 2-12 ).
CoNNeCTor FIGURE 2-12. REMOTE CONTROL 2.3.4. PLATFORM RING If the PS-40 is installed on MIl-STD-1913 rail, optional Platform ring is used for mounting optional Ir illuminator on dayscope hav- ing mounting diameter 25.4 or 30 mm (Figure 2-3). Attach the Platform ring to dayscope as follows (Figure 2-13): FIGURE 2-13.
(Figure 2-3). 2.3.6. B.A.M. SYSTEM optional B.A.M. system (Boresight Attachment Mount) is used to install the PS-40 and dayscope on the rifles having short mounting MIl-STD-1913 rail. There are three advantages of the system: • Low position of the sight and dayscope (36 mm above the rail).
8. Slightly loosen the two fixing screws  on the top rail . 9. Place the top rail onto the Picatinny rail on the top of the mount. 10. Tighten the fixing screws of the top rail. 11. Place the Night vision Front Sight  onto the top rail at front of the scope.
2.3.7. IR450 ILLUMINATOR Ir450-B4 illuminator provides the capability for operator to use the PS-40 under extremely low light conditions and in total dark- ness. The Ir illuminator can be mounted on rail of the Platform ring, or of the Scope Mounting System (Figure 2-15), or on top rail of the B.A.M.
The ATN Ir450 is powered with one Cr123A lithium battery. To in- stall the battery unscrew the cap of the battery housing and insert the battery following the polarity arrows marked on the housing. Put the cap in place. The Ir-450 illuminator has a control panel with two buttons. To switch the IR illuminator on/off press “+”...
2.3.8. DAY SCOPE LIGHT SUPPRESSOR To maximize usage of the PS-40 with a daytime scope a rubber light suppressor (DSlS) is included. The DSlS slides over the eyepiece of your daytime scope. The DSlS was designed to achieve several missions: 1.
To install the Extender Focus Knob (Figure 2-19): 1. Unscrew the fixing screw. replace it to short fixing screw  from extender Focus Knob Kit. Screw the new fixing screw  to the lug and tighten it. Do not over tight it avoiding irregular rotation of the focus ring.
However, some types of blemishes can get worse over time and interfere with the usabil- ity of the device. If you believe a blemish is a cause for rejection, warranty or repair please ATN or point of purchase for warranty/ repair procedures.
A bright spot is a small, non-uniform, bright area that may flicker or appear constant (Figure 3-3). Not all bright spots make the ATN PS-40 rejectable. Cup your hand over the lenses to block out all light. If the bright spot re- mains, return the ATN PS-40.
C. Black Spots These are cosmetic blemishes in the image intensifiers or dirt or debris between the lenses. Black spots are acceptable as long as they do not interfere with viewing the image. No action is re- quired if this condition is present unless the spots interfere with the usability of the device.
E. Chicken wire. An irregular pattern of dark thin lines in the field of view either throughout the image area or in parts of the image area (Figure 3-5). Under the worst-case condition, these lines will form hex- agonal or square-wave shaped lines. This is typically viewed in high light conditions.
PMCS is performed daily when in use to be sure that the sight is ready at all times. Procedures listed in Table 4-1 are a systematic inspection of the PS-40 that will enable you to discover defects that might cause the sight to fail on a mission.
