Input type Notes
Multi-inputs
6, 7 and 8
Binary mode: If the input is shown as ON in the display, the input for the regulator will be
100 %, otherwise 0 %.
4 to 20 mA: The input is always scaled in the range 4 mA to 20 mA. If a different range is
chosen in the 4 to 20 mA alarm parameters, the value shown in the display is scaled in rela-
tion to the chosen range.
RMI Fuel level/RMI Water temperature/RMI Oil pressure: The input is scaled in relation
to the selected curve for the selected RMI mode, either a predefined curve or the configura-
ble curve.
Pt1000 (multi-inputs 6 and 7 only): The input is scaled in the range -51 to 265 °C.
MPU input
(RPM meas-
urement)
Here the input is scaled in relation to the nominal rpm range 100 to 4000 rpm.
EIC Speed PGN 61444, SPN 190 Engine Speed*
If the input telegram does not contain a valid value, the used input value will be the last
known valid value. The last valid value is zero if no valid values have been received since
power-up. The input from the EIC is being scaled in the rpm range 100 to 4000 rpm.
EIC Ambient
Air Temper-
ature
PGN 65269, SPN 171 Ambient Air Temperature*
If the input telegram does not contain a valid value, the used input value will be the last
known valid value. The last valid value is zero if no valid values have been received since
power-up. The input from the EIC is being scaled in the temperature range -40 to 210 °C.
EIC Coolant
Temperature
PGN 65262, SPN 110 Engine Coolant Temperature*
If the input telegram does not contain a valid value, the used input value will be the last
known valid value. The last valid value is zero if no valid values have been received since
power-up. The input from the EIC is being scaled in the temperature range -40 to 210 °C.
EIC Oil
Temperature
PGN 65262, SPN 175 Engine Oil Temperature 1*
If the input telegram does not contain a valid value, the used input value will be the last
known valid value. The last valid value is zero if no valid values have been received since
power-up. The input from the EIC is being scaled in the temperature range -40 to 210 °C.
*The telegrams specified here are part of the J1939 standard. For communication protocols that do not use
J1939, consult the document "Option H5, H7 and H13 MTU MDEC, ADEC, J1939 CANbus engine interface".
9.1.7 Regulator outputs
It is possible to choose three types of outputs for the regulator. If the same output is selected for two or more
regulators, the regulator with the lowest number will be the one with the highest priority. An example would be
for PID2 and PID3 to have the same output, PID2 would then be the one with the highest priority.
Relay control
If relay control is chosen as the output for a regulator, the regulator requires two unused relays. The relays
can be configured in the parameters 2830, 2870 and 2910 for the different regulators.
The relay regulation is controlled with a proportional gain, Kp, and a deadband. By selecting a higher Kp, the
regulator will be more aggressive. The deadband is like a deadzone. If the deadband is 5 % and the refer-
ence value is 50, the regulator will not do anything when the actual value is in the range of 47.5 to 52.5. A
deadband under 0.2 % is not recommended for use with relay regulation.
