Setpoints for Tachometer
The tachometer is used in order to display the engine RPM and the tachometer is used in order to control four outputs: "Crank Terminate", "Crank Terminate Time Delay", "Engine Oil Step" and "Overspeed". See Table 3 for setpoints.ReferenceRefer to Service Manual, RENR5851, "3606, 3608, 3612, 3616 and 3618 Engines Tachometer" for calibration procedures for the tachometer.

The pyrometer is an electronic scanner for exhaust temperatures. The pyrometer monitors the temperature of each cylinder exhaust port. The pyrometer also monitors the exhaust temperature at the turbocharger inlet. If the engine has two turbochargers, the pyrometer monitors the exhaust temperature at both turbocharger inlets. See Table 4 for setpoints.ReferenceRefer to Service Manual, RENR4911, "Exhaust Temperature Scanner" for calibration procedures.
