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. | |
| 211 | HIGH COOLANT TEMP | Indicates the engine coolant temperature is getting close to the recommended maximum temperature limit: 215° F (102° C) − standby or 207° F (97° C) − 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 HIGH COOLANT TEMP 212 − SHUTDOWN procedure. To check coolant temperature, access the coolant temperature menu prior to clearing the fault. | |

| 214 | LOW COOLANT LVL Warning | ||
| 214, 215 | Shutdown lamp lights. MESSAGE: LOW COOLANT LVL or LOW COOLANT LVL | Indicates engine coolant level has fallen below the trip point. Allow engine to cool down completely before proceeding. a. Check coolant level in both radiator and coolant recovery bottle and replenish if low. Look for possible coolant leakage points and repair if necessary. b. If radiator level is low and coolant bottle level is correct, defective coolant bottle hose or radiator cap. c. Reset control and restart after locating and correcting problem. LOW COOLANT LVL Shutdown will not occur if genset is in Idle mode (low coolant warning only). | |
