4-CONTROL SYSTEM
4.1.Introduction
Programmable microprocessor based controller units are used in TEKSAN generator sets as a standard. These
controllers are capable of monitoring any electrical or mechanical changes or parameters on the generator set.
They also provide all necessary mechanical and electrical protections for the generator set.
The control systems in general, allow the user to run or stop the generator set. They also monitor and control the
measurement and protection circuits installed on the generator set. Since the controller unit is programmable, it
also provides flexibility in terms of usage under different conditions.
The control panels used on TEKSAN generator sets, are manufactured using A1 quality steel sheets and
coated with electrostatic powder paint in order for preventing corrosion. Manual (TJM), automatic (TJA) and
synchronization (TJPS) control panels are manufactured as a standard in TEKSAN. But it is also possible to design
customized control panels for different purposes or scenarios of usage.
Further details about the controller unit can be found in the additional manuals provided with the generator set.
4.2.Manual and Automatic Control Panel
Automatic control panels are used in applications in which the generator set is a secondary/back-up power source
for the mains power in order to ensure that the generator set starts and supplies power when the mains power
gets off.
Manual control panels are used in applications in which the generator set is a primary/main power source and they
start and supply power when it is necessary and when the generator set gets started manually.
In both scenarios and panels, the microprocessor based TJ509-T controller manages all needs to be done like;
“monitoring the mains power”, “starting or stopping the generator set depending on the status of mains power”,
“protection of engine/alternator or any other equipment on generator set system”, “transferring the load between
mains and generator set”.
The modes of operation can be changed by pressing the relevant button on front panel and changing the operation
mode while a generator set is running, results in a behaviour change on the generator set depending on the
operation mode selected. For example; if “MANUAL/RUN” mode is selected, the controller gets into manual mode
and any process like running the generator set, opening/closing the mains/generator contactors requires manual
interference.
STOP: This mode is used for stopping the generator set or keeping it stopped at rest. Once this mode is selected
on controller; the generator set does not run and stops if it is already running. Then the generator set contactor
gets opened and the mains contactor gets closed for transferring the load to mains and supplying the load from
mains.
When the STOP button is pressed once, the controller starts the usual “stopping sequence” and stops the engine
after an “engine cooldown” process. For stopping the generator set immediately, the STOP button should be
pressed twice.
