WARNING:

 

Before opening the instrument make sure that the mains cable is separated from the instrument. 

 

 

WARNING:

 

Some of the modules need alignment after being exchanged.  Therefore it is important to go through all the steps 
described in exchanging the module that needs to be replaced. 

 

WARNING:

  

Electronic circuits of the OCTOPUS 300, particularly the 'Processor board', the 'Interface board' and the LEDs in 
the 'Background LED module' are all very sensitive to electrostatic charges. Keep all modules in static shielding 
bags for storage, transportation and shipping. 

 

Besides an ordinary set of regular tools the following tools and instruments are recommended: 

 

Set of Allan- (hexagonal) wrenches, metric 1.3 to 8mm 

 

Set of Torx screwdrivers (the sizes in this manual refer to the screwdriver size) 

 

Universal digital voltmeter, range 200mV to 250V 

 
 

Cleaning Materials

 

 

Can of compressed air 

 

Lens tissue 

 

Lens cleaner (diluted alcohol) 

 

Cotton swabs 

 
Whenever possible, field repairs of the OCTOPUS 300 should be restricted to module exchange. The sub module (part) causing a 

problem should be localized with the help of the service manual and error list. It should then be replaced with an exchange module.

Housing (1805001) 

 

Housing left  

 

Housing right  

 

Housing top 

 

 

NOTE: 

 

If the 'Housing' is removed, the perimeter will only initialize and calibrate correctly if it is placed in an entirely dark 
environment. The covers can temporarily be put back in place for its operation and to run the 'Service programs' 
such as the 'General test' in a semi-dark room. 

 

Removal 

 

Remove the 'Housing top' by removing the four Phillips (M4) screws in each outer corner from the bottom part of the 'Housing 

left' and 'Housing right' (see Figure 7-1).
