User Interface
All user interface ports are equipped with a safety interlock system which warrants laser safety.
These interlock devices must not be manipulated. Other interfaces which are not described here
are service interfaces and are only to be operated by authorized Carl Zeiss service personnel.
The following devices can be mounted and dismounted by the user or are accessible by the
user:
−
Halogen lamp,
−
Transmission PMT,
−
Switching Mirror,
−
Scan heads,
−
NDD's (see CHAPTER 8: "MULTIPHOTON
LASER SCANNING MICROSCOPY …" for
details),
−
ConfoCor 3 filter wheels (exempt the
block filter wheel),
−
ConfoCor 3 external connectors,
−
LSM 780 / 710 filter wheel
1.11.1
Mounting and Dismounting Lamps, TPMT and Switching Mirror
The ports of the lamps, the switching mirror and the transmission PMT are equipped with hardware
interlock devices which have to be operated in the following way:
Interlock with sensor ring and contact ring:
Fig. 19
Sensor ring mounted to the inter-
face ports on the microscope side
Fig. 20
Contact ring mounted to the lamp,
TPMT or switching mirror
The interlock is working when the sensors of the sensor ring (Fig. 19/
1
) are depressed by the pins on the
contact ring (Fig. 20/
1
). Whenever this is not the case, for example if the distance between the two
devices is too large, the laser will be blocked and the system cannot be used.
In case the system is not operating following the removal or attachment of any device on a port
with safety interlock check again the connection of the Contact ring to the Sensor ring.
