Normal Engine operational ranges?

I’m in the process of setting the engine gauge display up on the GPSMAP 7610. Specifically the normal operating ranges (low-high) for the various engine sensors. This is for a Volvo D3-220. The operating manual only shows ranges for oil pressure (3-6 bars) and coolant temp (167-203F). I can’t find the range for Oil Temp for example or for any other sensor. I have looked at the Volvo site and used Google but no joy. I got hold of the Workshop Manual but found nothing there either. Can anyone point me in the direction to where this might be documented?
Thanks,

oil temp max - engine will go into derate 135 °C (275 °F)
coolant temperature -alarm 98 °C (208.4 °F). derate 101 °C (213.8 °F)
intake manifold air max temperatures 80 °C (176 °F). Alarm. 90 °C (194 °F) derate

Thermostat begins to open 176 F and full open 201F
Charge air pressure at intake manifold 15.2 PSI to 40.5 PSI(boost pressure -14.7 psi) I see 28 PSI at WOT
oil pressure range 50 PSI to 94 PSI

The best way to set perimeters, record the pressures and temperatures of your engine at idle, slow cruise and high speed cruise and WOT. Use these numbers has your normal average operating ranges. If you notice a change then you have a recorded comparison. Set your perimeters based on your engine results. The engine sensor ranges are much higher and lower than normal operating ranges.
 
Brian, thanks for the various values you provided. I like your suggestion of recording temps/pressures during different speeds and use those values as perimeters on the GPSMAP engine display page. Excellent and very helpful.
