Paul,
Some later PS3 steamers, I've found, will come up in conventional mode if power is applied by ramping it up too slowly. However, a simple Shut Down should put each into DCS mode, dark and silent.
To startup your lashup without any issues, I suggest the following:
- Use either TIU Tracks or Z4K Tracks to control your TIU channels. Then, configure these tracks so that upon turning up the thumbwheel, the track voltage goes directly to your preferred DCS operating voltage, typically 18 volts.
- Then, select the lashup and press Startup.
Alternatively, keep the lashup on a siding that's controlled by a toggle switch and proceed as follows:
- Highlight the lashup in the DCS engine list, either the Active list or the Inactive list.
- Flip on the toggle switch and then quickly press the thumbwheel.
- Then, if the engine went from the Inactive list to the Active list, select it again and press the thumbwheel.
- Last, press Startup.
Either method works every time for me, with steamer lashups that are all PS3, or mixed PS2 and PS3. It's all in the book!
