| 200 | Shutdown lamp lights. | Indicates engine oil pressure has dropped to an unacceptable level. If generator is powering critical loads and cannot be shut down, wait until next shutdown period then follow 201 Low Oil Pressure procedure. If engine can be stopped, follow 201 procedure. To check oil pressure, access Oil Pressure menu prior to clearing the fault. |
| 210 | Warning lamp lights. | Indicates set is in standby mode but is not operating. Warning occurs when engine coolant temperature is 70 F (21 C) or lower. NOTE: In applications where the ambient temperature falls below 40F (4C), Low Engine Temp may be indicated even though the coolant heaters are operating. Indicates engine coolant heater is not operating or is not circulating coolant. Check for the following conditions: a. Coolant heater not connected to power supply. Check for blown fuse or disconnected heater cord and correct as required. b. Check for low coolant level and replenish if required. Look for possible coolant leakage points and repair as required. c. Contact an authorized service center if none of the above. |
| 220 | Indicates engine coolant level has fallen below the trip point. Shutdown lamp lights. | A. Check coolant level and replenish if low. Look for possible coolant leakage points and repair if necessary. b. Reset control and restart after locating and correcting problem. Contact an authorized service center. |
| 221 | Engine will not crank. Shutdown lamp lights. | A. Poor battery cable connections. Clean the battery cable terminals and tighten all connections. b. Discharged or defective battery. Recharge or replace the battery. c. Contact an authorized service center for service of starter and starting system. |
| 222 | Engine stops cranking. Shutdown lamp lights. | A. Check for empty fuel tank, fuel leaks, or plugged fuel lines and correct as required. b. Check for dirty fuel filter and replace if necessary. c. Check for dirty or plugged air filter and replace if necessary. d. Reset the control and restart after correcting the problem. Contact an authorized service center if none of the above. |
| 223 | Engine runs and then shuts down. Shutdown lamp lights. | Contact an authorized service center. |
| 230 | Battery voltage is below 24 VDC. Warning lamp lights. | A. Discharged or defective battery. Check the battery charger fuse. b. Poor battery cable connections. Clean the battery cable terminals and tighten all connections. c. Contact an authorized service center if none of the above. |
| 231 | Battery voltage exceeds 32 VDC. Warning lamp lights. | Contact an authorized service center. |
