preheating is requested, the intake air temperature is regulated according to the configurable

target value. The controller actuates the control valve of the heat exchanger unit

[VAWT/VSWT]Measurement of the heating water temperature upstream of the exhaust gas heat

exchanger and before lubricating oil heat exchanger

[SPC] Connection for service PC: Rugged service connector at the TEM-EVO unit control

cabinet. When the service PC is connected, a control unit will interrupt the connection to the

workstation or any modem that might be connected. The TEM-EVO system can then be

operated from the service PC

[2xNKAT] To protect the catalytic converter, the TEM-EVO measures the exhaust gas

temperature after the catalytic converter and monitors it in dependence on the operating point. A

malfunction will be triggered if the configurable limit value is exceeded

Operation

An intelligent workstation provides access to all functions ensuring easy operation of the TEM EVO

system The workstation is equipped with a 15" TFT touch monitor. The touch function of the workstation

ensures easy and intuitive operation of the unit. Using the navigation bar, the user can operate the unit

by quick and direct changing between screens. Each workstation screen provides the user with

information on the state of the connected unit. All regulation, service, control and monitoring functions

can conveniently be operated without the need for long training.

Communication with the user can be in one of many available national languages of the TEM EVO

system. The language can quickly be changed at any time by pressing a button. In the event of a

service, a different language than the one used by the plant staff may temporarily be set. All information

that is important for normal operation and operating options are clearly summarised on the "Operation"

screen (Fig. 1) (the figure below also contains options).


Figure 1: The most important information and operating options at a glance

Operation diary

With its recording function, the electronic operation diary (Fig. 2) of the TEM-EVO system makes the

operation of the gas engine plant and its peripheral devices transparent. All operation messages and

switching actions that are important for the operation as well as any changes to the configuration are

recorded with the exact time stamp (date/time). In total, the TEM-EVO system can monitor and

distinguish more than 600 different incidents. This allows for quick and detailed analysis of the operation

of the unit incl. the auxiliary functions controlled by the TEM EVO.


Figure 2: Recording functions of the operation diary

The curves can be followed with the cursor; the respective measured value is depicted as numeric value

with exact time stamp. In the event of a failure, the recording will stop automatically after 40s to facilitate

failure diagnosis. The "Real-time scope" function allows for continuous monitoring of measured values

and control function.

These measured values can optionally be saved for further analysis and re-read at a later time.
