Person sensor (option)

The dark flap can be opened automatically via a sensor when you look through the microscope and closed again when you look away.

This is achieved by mounting the person sensor (order no. 505 101) onto the right eyepiece tube and connecting the cable on the sensor to the SHUTTER socket on the control unit for motor- ised filter cube change.

Switch position AUTO

The dark flap is opened when you look through the eyepiece. When you move away, it will be closed again after about 3 seconds.

Switch position LIGHT ON

The dark flap remains open (e. g. for photo- micrography). If the flap is still closed, it must be opened first manually. It will then remain open.

The diode next to SHUTTER CLOSED indicates whether the dark flap is currently open (diode off) or closed (diode on).

You can control the dark flap manually by pressing the key above SHUTTER CLOSED or with the SHUT key on the control unit.

When the microscope is switched on the dark flap is closed at first. To activate the person sensor you first have to open the dark flap manually.

Switch position SENSOR OFF

The person sensor is switched off. The position of the dark flap remains unchanged.

n. b.:

The shutter key on the microscope or on the control unit can be operated at any time. The SHUTTER CLOSED diode indicates whether the flap is currently open or closed.

If the dark flap is closed before the automatic functions are switched on, it has to be opened manually before the automatic functions take effect.
