9.1 Safety interlock
The use of the safety interlock protects the device from damage in many situations.
Nevertheless, depending on the parameters of the laser beam to be measured, damage
to the absorber may occur. Please observe the specifications and limit values given in
chapter19, „Technical data“, on page50.
During irradiation, the temperature of the absorber can rise significantly above 100°C
for a short time because the heat has not yet been distributed evenly in the absorber. To
avoid triggering the safety interlock during irradiation in this case, the safety interlock is
only triggered at a temperature above 200°C when irradiation is in progress.
Therefore, when a running irradiation is detected, the interlock threshold is temporarily
increased from 100°C to 200°C. After the end of the irradiation, the interlock threshold
is reduced again to 100°C.
If the temperature of the absorber is above 100°C after the measurement is completed,
the safety interlock is triggered to protect the absorber. This prevents the device from
being irradiated again.
Pin 3 and pin 4 are connected when a safety interlock is triggered. After the absorber
has cooled down, pin 1 and pin 4 of the safety interlock are connected.
