2.2.11 Rated Photodiode
The photodiode emits a source of infrared light which is detected by the phototransistor.
These devices are intended to be used in pairs.
You must specify a light channel in each of these paired parts (photodiode and
phototransistor). This is done in the
Valu e tab of the component’s properties screen. Each
diode must have a different value for its light channel, however, the phototransistor can share
the same value with several other phototransistors.
 To adjust the component’s tolerances:
1. Double-click on the placed component and click the Value tab.
2. Change the following values as desired:
•
Animation Delay Factor — increase this number to slow the speed of animation of the
symbol blowing. This is not a real-time value.
•
Light Channel (Integer) — set to match the light channel for the corresponding
phototransistor(s).
•
On Current (Ion) — set as desired.
•
Reverse Breakdown Voltage — set as desired.
•
Maximum Rated Power (Watts) — If this value is exceeded during simulation, the
photodiode blows.
3. Click OK.
2.2.12 Rated Phototransistor
The photodiode emits a source of infrared light which is detected by the phototransistor.
These devices are are intended to be used in pairs.
