BENTLY 3300/16-04-01-01-00-00-00間隙監視器
確定發(fā)動(dòng)機是否有故障。確認燃油齒條未卡滯，連桿調整正確。確定燃油齒條是否快速跟隨執行器輸入電壓。檢查超速保護裝置的運行情況。原動(dòng)機僅在啟動(dòng)時(shí)超速或產(chǎn)生過(guò)量煙霧。啟動(dòng)燃油限制處于非活動(dòng)狀態(tài)。通電后，如果MPU信號在不到1秒的時(shí)間內清除，則可以繞過(guò)Fuel Limit（燃油限制）。啟動(dòng)發(fā)動(dòng)機前，接通2301A電源。2301A控制。如果控制裝置在速度設置完全逆時(shí)針（或在任何位置都不減少燃油）之前沒(méi)有降低執行器電壓[T20（+）和T21（-）]，則2301A控制裝置可能有故障，或速度范圍錯誤。如果電壓降低，檢查連桿或執行器有無(wú)故障。原動(dòng)機在額定速度下運行一段時(shí)間后超速。原動(dòng)機。檢查原動(dòng)機燃油系統是否正常工作。如果執行器在超速期間向最小燃油方向移動(dòng)，則問(wèn)題出在燃油系統中。電磁拾波器和2301A控制。檢查轉速高于怠速至少1.0 Vrms時(shí)的電磁拾波器輸出電壓。如果磁性撿拾器出現故障并且超越故障轉速信號電路被禁用，則2301A控制裝置將需要最大燃油量。以額定速度手動(dòng)控制原動(dòng)機，并完全逆時(shí)針調整額定速度設置。如果輸出電壓不為零，請按照第2章所述檢查速度范圍開(kāi)關(guān)調整是否正確。如果速度范圍適合應用，請更換控制器。
低速不由Low IDLE speed（低怠速）電位計調節。
低怠速設置可能低于執行器或原動(dòng)機燃油擋塊的最小燃油位置。在這種情況下，執行器的輸出電壓將為零。發(fā)動(dòng)機將通過(guò)執行器或原動(dòng)機最小燃油擋塊保持在最小燃油位置。上述情況表明，應通過(guò)連桿調整（柴油發(fā)動(dòng)機）或低怠速調整螺釘（燃氣發(fā)動(dòng)機）降低原動(dòng)機最小燃油位置，或提高低怠速設置。如果上述操作不能解決問(wèn)題，則2301A控制裝置可能有故障。當觸點(diǎn)斷開(kāi)時(shí)，額定觸點(diǎn)的故障閉合可能會(huì )保持在加速位置。如果額定觸點(diǎn)閉合工作，怠速控制損失可能是由于電路故障造成的。通常，低怠速的調整將改變原動(dòng)機的速度，額定觸點(diǎn)閉合處于減速（斷開(kāi)）位置。當額定閉合觸點(diǎn)閉合時(shí)，低怠速的調整不應影響原動(dòng)機速度。警告：速度設置控件有足夠的范圍覆蓋斜坡，使原動(dòng)機速度達到額定速度，同時(shí)仍處于低怠速模式（通過(guò)缺陷或切換）。因此，如果在T19打開(kāi)的情況下將額定轉速設置調整為額定轉速，則間歇的額定觸點(diǎn)閉合可能會(huì )導致原動(dòng)機超速。
Determine if engine is malfunctioning.
Verify that fuel rack is not binding and linkage is properly adjusted. Determine if the fuel rack is quickly following the actuator input voltage. Check operation of overspeed protection device(s). Prime mover overspeeds or causes excessive smoke only on starts. Start Fuel Limit is inactive. On power up, Fuel Limit can be bypassed if MPU signal clears in less than 1 second. Power up 2301A before cranking engine. 2301A control. If the control does not cut back the actuator voltage [T20 (+) and T21 (–)] until the speed setting is completely counterclockwise (or does not reduce fuel at any position), the 2301A control may be faulty, or may have the wrong speed range. If the voltage is cut back, look for a problem in the linkage or actuator. Prime mover overspeeds after operating at rated speed for some time. Prime mover. Check for proper operation of prime-mover fuel system. If actuator moves toward minimum fuel during overspeed, problem is in fuel system. Magnetic pickup and 2301A control. Check the magnetic-pickup output voltage at speeds above idle-at least 1.0 Vrms. If magnetic pickup should fail and the override-failed-speed-signal circuit is disabled, the 2301A control will call for maximum fuel.Control the prime mover manually at rated speed and adjust the RATED SPEED setting fully counterclockwise. If the output voltage is not zero, check for proper speed range switch adjustment as described in Chapter 2. If speed range is correct for the application, replace the control.
Low speed is not regulated by LOW IDLE SPEED potentiometer.
The LOW IDLE SPEED setting may be below the minimum-fuel position of the actuator or prime-mover fuel stop. In this case, the output voltage to the actuator will be zero. The engine will be maintained at the minimum-fuel position by the actuator or the prime mover minimum-fuel stop. The conditions above indicate that the prime mover minimum-fuel position should be decreased by linkage adjustment (diesel engine) or low-idle set screw (gas engine), or the LOW IDLE SPEED setting should be raised. If the above action does not correct the problem, the 2301A control may be faulty.A faulty Close for Rated contact may remain in the accelerate position with the contact open. If the Close for Rated contact is operative, loss of idle control may be due to a faulty circuit. In general, adjustment of LOW IDLE SPEED will vary the speed of the prime mover with the Close for Rated contact in the decelerate (open) position. Adjustment of LOW IDLE SPEED should not affect prime mover speed when the Close for Rated contact is closed. WARNING The speed-setting controls have sufficient range to override the ramp and bring the prime mover speed up to rated while still In the low-idle mode (either by defect or switching). Therefore, a Close for Rated contact that is intermittent may cause the prime mover to overspeed if the RATED SPEED setting is adjusted for rated speed with T19 open.
