Setpoints For Timers
The following timers use 10 dip switches in order to set the time delay.
- Timer (Engine Speed)
- Timer (Engine Oil Level)
- Timer (Engine Oil Level)
- Timer (Low Starting Air Pressure)
The switches are numbered from 1 to 10. The switches are two-position switches: "OPEN" and "CLOSE". See Table 1 for times of each switch.
| Switch Number (OPEN) | Time (Seconds) |
|---|---|
| 1 | 1 |
| 2 | 2 |
| 3 | 4 |
| 4 | 8 |
| 5 | 16 |
| 6 | 32 |
| 7 | 64 |
| 8 | 128 |
| 9 | 256 |
| 10 | 512 |
Note: The first second is not a full second. Therefore, one second can be added to the time that is needed for a more accurate reading.
See Table 2 for proper settings.
The following timer uses a dial in order to set the time delay.
- Timer (Post Lubrication)
The dial uses a pointer in order to point to a number that represents the time delay in minutes.
| Timer | Label | Time Delay (seconds) | Switches "OPEN" (1) |
|---|---|---|---|
| Engine Speed | "SPFTD" | 3 | 1, 2 |
| Engine Oil Level | "OLLTD" | 5 | 1, 3 |
| Low Starting Air Pressure | "ASPTD" | 5 | 1, 3 |
| Particle Detector | "PDSTD" | 5 | 1, 3 |
| Post Lubrication | "PLTD" | 1 | N/A |
| ( 1 ) | All other switches will be in the CLOSED position. |
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.

Parameters for Pyrometer
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.
| Description | Displayed | Value |
|---|---|---|
| Number of engine cylinders | "CYLINDERS" | The actual number |
| Number of turbochargers | "TURBOS" | The actual number |
| Display only the turbocharger outlet temperature. Display only the turbocharger inlet temperature. Display the turbocharger outlet and inlet temperatures. |
"TURBO OUT" "TURBO IN" "TURBO OUT AND TURBO IN" |
"TURBO IN" |
| Units for the display | "UNITS" | "DEG C" |
| Automatic scanning or manual scanning | "AUTOSCAN" | "YES" |
| Value for the scanner's filter | "FILTER VALUE" | 230 |
| Setpoint for exhaust port temperature deviation | "SET CYL DEV" | "OFF" |
| Setpoint 1 for high cylinder exhaust temperature | "SET CYL HI 1" | "OFF" |
| Setpoint 2 for high cylinder exhaust temperature | "SET CYL HI 2" | "OFF" |
| Setpoint 1 for high turbocharger outlet temperature | "SET TO HI 1" | "OFF" |
| Setpoint 2 for high turbocharger outlet temperature | "SET TO HI 2" | "OFF" |
| Setpoint for high turbocharger inlet temperature | "SET TI HI" | 630 for standard 650 for HI Output |
