REFERENCE MANUAL

General specifics: Electronic board TE208 controls and protects diesel engines in their applications, in specific way it controls generating sets : Electronic protection modul for diesel generating sets;. Display to shows battery voltage (Vdc), hourcounter (H), generator voltage (Vac), current (A) and frequency (Hz); Withdrawable terminals boards: - input and supply terminal board (7 poles); - output terminal board (6 poles); - generator current terminal board from CT, max. 5A (2 poles 5,08mm); - generator voltage terminal board, max. 265V(2 poles 7,62mm). Supply voltage: 917Vdc (ver. 12V); 2030Vdc (ver. 24V). Frequency: 5 99Hz. Display: 4 digit, 7 segment led. Starting key with 3 steps (OFF, ON and START)

Inputs with signalations:

L1-D+ alarm from batterycharger alternator: is on also before and during the start. In case of alarm (if D+ is less then 6Vdc for more then 3 seconds) generator stops, the alarm output is closed (to supply eventually a siren), and led L1 turns ON. Turn the key to OFF position for at least 3 seconds to reset the alarms.

L2-Fuel reserve alarm: delayed 8 seconds after the start. In case of alarm (if signal close to negative for more then 3 seconds) generator stops, the alarm output is closed (to supply eventually a siren), and led L2 turns ON. Turn the key to OFF position for at least 3 seconds to reset the alarms.

L3-High engine temperature alarm: delayed 8 seconds after the start. In case of alarm (if signal close to negative for more then 3 seconds) generator stops, the alarm output is closed (to supply eventually a siren), and led L3 turns ON. Turn the key to OFF position for at least 3 seconds to reset the alarms.

L4-Low oil pressure alarm: is on also before and during the start. In case of alarm (if signal close to negative for more then 3 seconds) generator stops, the alarm output is closed (to supply eventually a siren), and led L4 turns ON. Turn the key to OFF position for at least 3 seconds to reset the alarms.

L6: Glow-plugs preheating status LED

L7: Emergency button alarm

L8: High/low RPM alarm from frequency

L4: Low oil pressure alarm

L3: Engine high temperature alarm

Button to change the measurements in the display.

Key selector switch with 3 steps: OFF: all off, board waits remote start signal; you can remove the key ON: board supplied, glow-plugs preheating and ready for starrting START: starting of the engine; when you release the key, it returns in ON position.

L5: Engine running status LED

L2: Fuel reserve alarm

L1: D+ alarm from batterycharger alternator

Display measurements: - Battery voltage (Vdc); - Hourcounter (H); - Generator voltage (Vac); - Current (A); - Frequency (Hz).



L7-Emergency button alarm: in case of alarm (if signal close to negative for more then 0,2 seconds) generator stops, the alarm output is closed (to supply eventually a siren), and led L7 turns ON. Turn the key to OFF position for at least 3 seconds to reset the alarms.

Inputs without signalations:

Remote start: in case of this input closed to positive, the board turns ON and it begins the starting procedure. This procedure is with 5 start attempts of 10 seconds lenght each, with 20 seconds of pause and stop procedure between one attempt and the next one. During a start attempt, when the board see the engine running status, it re-opens the starting output, to prevents cranking motor damages.

Functions with signalations:

L6-Glow-plugs preheating status: when the key turn sto ON position, glow-plugs output close and the L6 led turns ON for 8 seconds.

Measures with signalations:

L5-Engine running status: the board see the engine running status when the frequency is more than 9Hz; by this the L5 led start blinking. This blinking status shows you that the engine is running but not all the alarms are enable (this permits to the generator to reach nominal values without false alarms). After this time of 8 seconds, led L5 turns ON to shows that the engine is running and all the alarms are enable.

L8-Over/under speed alarm: the boards measures the frequency to check the low and high speed of the engine. In case of alarm, generator stops, the alarm output is closed (to supply eventually a siren), and led L8 turns ON. Turn the key to OFF position for at least 3 seconds to reset the alarms. The alarm is detected in accordance to the following data: For 50Hz nominal setting

- Frequency less than 47Hz or more than 53Hz for at least 5sec. - Frequency less than 46Hz or more than 54Hz for at least 2sec. - Frequency less than 45Hz or more than 55Hz for at least 0,3sec.

For 60Hz nominal setting - Frequency less than 57Hz or more than 63Hz for at least 5sec. - Frequency less than 56Hz or more than 64Hz for at least 2sec. - Frequency less than 55Hz or more than 65Hz for at least 0,3sec.

Measures on the display: On the display you can select the following measures by Select/Mis button:

- Vdc: ......battery voltage measure showed with two whole numbers and one decimal (ex: 12,5V); - H:..........working hours measure (detected and counted when the board see the generator voltage) in thousands of hours (ex: 0034); - Vac: ......generator voltage measure showed with three whole numbers (ex: 230V). By setting, is possible to show the voltage

between phase and neutral like 230Vac for monophase generator on the display or, for triphase generators, the board can converts the 230Vac between phase and neutral to 400V showed on the display.

- A: ..........generator current measure showed with three whole numbers and one decimal (ex: 100,3A); the internal Current Transformer ratio fixed is 80 (for 400/5A CT)

- F=Hz:....generator frequency measure showed with two whole numbers and one decimal (ex: 50,3Hz); by setting you can change the nominal frequency to 50Hz or 60Hz

Uscite: Start................................................ NA - It close to positive during the start rel 15A max Stop electrosolenoid (J1 close) ...... NA - It close to positive during the stop rel 15A max Stop fuel electrovalve (J1 open) .... NC - It open from positive during the stop rel 15A max Siren alarm..................................... NA - It close to positive in case of alarm rel 5A max Glow-plugs..................................... NA - It close to positive before starting rel 5A max D+ pre-excitation .......................... 140mA - 12Vdc



Operating mode:

Key in OFF position. All off and no battery consumption; only in this position is possible to remove the starting key. The board waits an eventual remote start signal. With engine running, if you turn the key in OFF, the stopping procedure begins. Stop procedure (the same also in case of alarms or after a remote start), is by de-excitation of fuel electrovalve if jumper J1 is open (energize to run system) or is by excitation of electrosolenoid for 20 seconds if jumper J1 is closed (energize to stop system). To turn off the board, remain for 3 seconds in OFF position (showed by a point on the display)

Key in ON and START positions. When the board is supplied by key in ON position, test leds occours for 3 seconds; after it all the function return to normal status. The board gives the glow-plugs output for 8 seconds (L6 ON) then, if there arent alarms, you can start the engine by key in START position. If during the glow-plugs preheating you turn the key in START position and hold it for 2 seconds, you stop the pre-heating and you give the start signal to the engine. Automatically when the board see the engine running status, it disables the start output also if you still remain in START position with the key. You can check the engine running status and the alarms disable time by led L5.

Contaore When the board detects the generator voltage, it counts the working hours. The board shows the working hours with 4 numbers; by this the board can shows maximum 9999 hours. To show higher values, the board use the point in the display: for sample, 10.00 on dsiplay indicates 10.000 working hours. The value is stored also if you disconnect the board from the battery supply and is not possible to reset it.

Voltage and Frequency setting

Is possible to set the monophase system 230Vac or the triphase system 400Vac (detected always by one phase and neutral). Is also possible to set the nominal frequency of the generator to 50Hz or 60Hz.

Voltage setting By Select Mis button, scroll the measurements on the display up to reach the Vac voltage. Push and hold Select Mis button for 5 seconds: the display shows and flashing the actual setting (230 or 400). Push shortly Select Mis button to change the setting from these two values; when the display shows the correct choice, push and hold Select Mis for 5 seconds to store the setting and exit.

Frequency setting By Select Mis button, scroll the measurements on the display up to reach the Frequency measure. Push and hold Select Mis button for 5 seconds: the display shows and flashing the actual setting (50 or 60). Push shortly Select Mis button to change the setting from these two values; when the display shows the correct choice, push and hold Select Mis for 5 seconds to store the setting and exit.
