5. The radiation in the source holder is thus switched on.
Radiation "ON" (1)
In the position recess of the operating lever the lettering "ON" is vis-
ible.
Radiation "OFF" (2)
In the position recess of the operating lever the lettering "OFF" is
visible.
Switching off the radiation is analogous to this procedure. To switch
off the radiation, turn the operating lever 90° anticlockwise to position
"OFF" (2).
The version with interlock safety switch allows switches, actuators,
valves, doors or safety fences to be secured.
To reach, for example, the key to an access door or safety fence, the
source holder must necessarily be switched off. Only then can the
access point to the radiation hazardous area be opened.
The requirements on function and design of the safety switch are,
however, extremely different, making it impossible to mount a certain
switch version in advance.
For that reason there is only a mounting plate for the interlock safety
switch. The safety switch itself must be provided by the customer.
The safety bolt of the interlock switch must have a diameter of 16 mm
(e.g. Superior Interlock type B-4003).
The mounting plate has the following holes:
