Section 3 - Operation Liquid-cooled 15, 20 and 25 kW Generators 3.7 CONTROL BOARD DIP SWITCH SETTINGS Located on the control board is an eight position DIP switch (see Figure 3.2). The eight different switches, are used to configure the control board for the specific engine and governor being used and are pre-set at the factory. ! If the DIP switch settings are not set correctly, the generator may not start or operate correctly. 240 VAC can be present within the control panel. If it is necessary to select an alternate switch position, move the AUTO/OFF/MANUAL switch to the OFF position. Remove the 15 amp fuse in the generator control panel. Move the DIP switch position that needs to be changed to its new position. Wait five seconds, then re-install the 15 amp fuse. The ON position is marked on the switch and is shown in Figure 3.2. Switch Position 1 — Selects the generator alternator output frequency and is factory pre-set for 60 Hz. Switch Position 2 — Selects the type of transfer switch and is factory pre-set for an automatic transfer switch (ATS). Switch Position 3 — Selects the type of governor control used, and is factory pre-set for stepper motor operation. Switch Position 4 — Selects the type of fuel being used and is factory pre-set for natural gas (NG). Switch Position 5 — Selects the engine displacement and is factory pre-set for a 2.5 liter (2.5L) engine. Switch Position 6 — Selects the number of engine cylinders and is factory pre-set for four cylinders. Switch Position 7 — Selects the direction of rotation of the governor stepper motor and is factory pre-set for CCW rotation (rotation is observed looking at the stepper shaft as it moves from closed throttle to open throttle). Switch Position 8 — Selects whether the control is in the Normal Mode of operation or Test Mode. In the Normal Mode of operation, pre-determined governor gains are used and the gain trimpots on the control board (Gain, Stability, and Differential) are not active and have no effect on the gains. In Test Mode the gain trimpots are active and can be adjusted. See Section 3.3. 3.8 VOLTAGE REGULATOR ADJUSTMENT Four adjustment potentiometers are provided on the voltage regulator installed in the control panel (Figure 3.4). These are (a) voltage adjust, (b) gain, (c) stability and (d) underfrequency adjust. The voltage regulator potentiometers have been factory set and SHOULD NOT be adjusted. If however, adjustments are necessary, contact the local Dealer to implement the following procedure. High voltage is present inside the control panel during this procedure. 1. Disconnect all electrical loads from the generator (initial adjustments are done under no-load conditions). Figure 3.4 — Voltage Regulator 2. Connect an accurate AC voltmeter and AC frequency meter to the generator’s AC output leads. 3. On the voltage regulator, set the potentiometers as follows: A. Turn the Voltage Adjust pot fully counterclockwise (CCW). B. Set the GAIN pot to its centered (mid) position. C. Set the STABILITY pot to its centered (mid) position. D. DO NOT adjust the UNDERFREQUENCY ADJUST pot. 4. Start the engine. Let it stabilize and warm up at no-load. 5. Verify that the three voltage regulator’s LED’s are ON. 6. Check the reading on the AC frequency meter. Section 4 — Maintenance Liquid-cooled 15, 20 and 25 kW Generators 7. Turn the voltage regulator’s VOLTAGE ADJUST pot to obtain a line-to-line voltage of: A. 240 VAC if the generator has been configured for 60 Hertz operation. B. 200 VAC if the generator has been configured for 50 Hertz operation. 8. If the RED REGULATOR LED is flashing, adjust the STABILITY pot in either direction until the flashing stops. 9. Apply an electrical load and check the engine speed recovery. A. Adjust the UNDERFEQUENCY ADJUST pot CCW to reduce load during engine recovery. B. For flat regulation (no voltage decrease as frequency drops) set the UNDERFREQUENCY ADJUST pot fully CW. C. To obtain a constant voltage regulation as frequency decreases, set the UNDERFREQUENCY ADJUST pot fully CCW. 10. With the electrical load still applied, check the REGULATOR LED for flashing. If the LED is flashing, adjust the STABILITY pot until the flashing stops. 11. If better response is needed, adjust the GAIN pot clockwise (CW) as needed. Then (if needed) correct for stability by adjusting the STABILITY pot. 12. Turn OFF the electrical loads. 13. Verify that all the voltage regulator’s LED’s are ON. 14. Turn OFF the generator. 4.1 MAINTENANCE PERFORMED BY AUTHORIZED SERVICE FACILITIES A. EVERY THREE MONTHS 1. Check battery condition. 2. Inspect and test fuel system. 3. Check transfer switch. 4. Inspect exhaust system. 5. Check engine ignition system. 6. Check fan belts. B. ONCE EVERY SIX MONTHS 1. Test Engine Safety Devices (low oil pressure, low coolant level, high coolant temperature). C. ONCE ANNUALLY 1. Test engine governor; adjust or repair, if needed. 2. Clean, inspect generator. 3. Flush cooling system. D. FIRST 100 OPERATING HOU...
