The current (1) which flows through the optocoupler and the integrated drop-
ping resistor should be > 5 mA and should not exceed 20 mA.
Pearleye P-007 LWIR
For continuous periodical trigger the pulse must be at least 100 μs in length and
the periodic time must be exactly 24.96 ms ± 10 μs.
Pearleye P-030 LWIR
For continuous periodical trigger the pulse must be at least 82 μs in length and
the periodic time must be exactly 41.608 ms ± 20 μs.
Sensor temperature too low (pin 12, 13)
As long as the sensor operating temperature is too low, the sensor control out-
put at pin 12/13 remains active (transistor switched on). After the warm-up
period of the camera this output becomes inactive.

Caution
Pearleye P-007 LWIR / Pearleye P-030 LWIR: The current that
flows through the optocoupler should not exceed 20 mA (at 12
V, resistance of the optocoupler: R
v
600 ).
