Shutter not working correctly
1. If you found a shutter problem, first locate the Shutter Actuator:
2. When you can see the Shutter Actuator, press OK. The Shutter Actuator should move up for one
second and then move back down. If nothing moves up and down, the actuator may be faulty.
The following screen appears:
If you press OK, the Shutter Actuator should move up and down again. You can repeat this
operation as many times as you like, until you feel sure about the result.
NOTE: A delay of about 10 seconds is necessary between activations of the Shutter Actuator.
This means that, if you press OK again within 10 seconds, the Shutter Actuator will not move
immediately. This is completely normal and does not indicate any malfunction.
3. After you press Cancel to stop the shutter test, the front panel asks whether the Shutter Actuator
moved correctly and looked undamaged. Press OK if all is well, or Cancel if you saw some
problem.
4. If you press Cancel, the appropriate system error message is shown:
If the shutter actuator appears undamaged, the problem could be electrical. Check that the Shutter
Actuator cables are properly connected. If not, connect them.
If the connections are good, replace the Shutter Actuator, because the problem could be the
motor.
If the shutter actuator looks broken, replace it.
In each of these cases, stop the test at this point and start it again from the beginning.
