| 200 | 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. | |
| 200 | LOW OIL PRESSURE | If generator is powering critical loads and cannot be shut down, wait until next shutdown period and then follow 201-SHUTDOWN procedure. To check oil pressure, access the Oil Pressure menu prior to clearing the fault. | |
| 201 | Engine oil pressure has dropped below the shutdown trip point. | Check oil level, lines and filters. If oil system is OK but oil level is low, replenish. Reset control and restart. | |
| 201 | LOW OIL PRESSURE Shutdown lamp lights. MESSAGE: LOW OIL PRESSURE 201 − SHUTDOWN | Engine oil pressure has dropped below the shutdown trip point. | Check oil level, lines and filters. If oil system is OK but oil level is low, replenish. Reset control and restart. Oil pressure limits are listed in Specifications. Contact an authorized service center. |
| 204 | Engine oil pressure sender is not functioning correctly. | Check that the engine oil pressure sender is properly connected. Contact an authorized service center. | |
| 204 | Indicates that the engine oil pressure sender is not functioning correctly. | Check that the engine oil pressure sender is properly connected. Contact an authorized service center. | |
| 204 | OIL PRES SENDER | Check that the engine oil pressure sender is properly connected. | |
| 204 | OIL PRES SENDER Warning lamp lights. MESSAGE: OIL PRES SENDER 204 − WARNING | Check that the engine oil pressure sender is properly connected. Contact an authorized service center. | |
| 210 | LOW COOLANT TEMP | Set 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 40°F (4°C), Low Coolant 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. Open heater element. Check current draw of heater. | |
| 210 | LOW COOLANT TEMP Warning lamp lights. MESSAGE: LOW COOLANT TEMP 210 − WARNING | 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. | |
| 210 | Low Engine Temp | 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. | |

| 211 | HIGH COOLANT TEMP | Indicates engine has begun to overheat and coolant temperature has risen to an unacceptable level: (215° F − standby / 207° F − primary). If generator is powering non-critical and critical loads and cannot be shut down, use the following: a. Reduce load if possible by turning off non-critical loads. b. Check air inlets and outlets and remove any obstructions to airflow. If engine can be stopped, follow the next procedure. To check coolant temperature, access Coolant Temp menu prior to clearing the fault. | |

| 212 | HIGH COOLANT TEMP Shutdown lamp lights. MESSAGE: HIGH COOLANT TEMP 212 − SHUTDOWN | Indicates engine has overheated (coolant temperature has risen above the shutdown trip point: 223 F − standby / 215 F − primary) or the coolant level is low. Allow engine to cool down completely before proceeding with the following checks: a. Check coolant level and replenish if low. Look for coolant leakage and repair if necessary. b. Check for obstructions to cooling airflow and correct as necessary. c. Check fan belt and repair or tighten if necessary. d. Reset control and restart after locating and correcting problem. Contact an authorized service center if none of the above. |
