6. Regular field servicing

6 - 2. Removing / re-installing hammer sensor

Removing hammer  sensor

Remove the 2 mini DIN connectors. ( for Hammer and key sensor )

Loosen and remove the hexagonal screws and hold up the sensor straight up slowly to avoid gray-scale

shutter damage.

You can work this adjustment
under Stand-by mode.

Re-installing hammer  sensor

1, Put up the sensor above the action with a slant.

2, Check the both sensor attaching bolt in the middle and shutter checking hole together.

3, Put on the sensor solowly to the flat position.

4, Execute the sensor caliblation, 

always after removing, by using PRC100 controller.

     ( It takes around 3 minutes to complete.)

Note: No height adjustment is necessary but needs always caliblation to get correct height information.
