Screed Heater Error Codes
Table 1
Fault Code     Flash Sequence (1)     Device at Fault     Cause of Fault     System Check point    
1     long long long short     Left hand extender heater circuit     The generator is not switched on, or the generator is operating outside of normal power range.     Check that the generator is on. Check the circuit breaker.    
2     short short short long     Left hand main heater circuit     The generator is not switched on, or the generator is operating outside of normal power range.     Check that the generator is on. Check the circuit breaker.    
3     long short short long     Right hand main heater sensor     The generator is not switched on, or the generator is operating outside of normal power range.     Check that the generator is on. Check the circuit breaker.    
4     short long short long     Right hand extender heater circuit     The generator is not switched on, or the generator is operating outside of normal power range.     Check that the generator is on. Check the circuit breaker.    
5     long long short long     Engine sensor     The sensor is operating outside normal operating range.     Check engine RPM/load factor signal loss    
6     short short long long     Screed can bus link     The link has been broken or disconnected.     Check for signal loss from the can bus.    
7     long long short short     Left hand extender temperature sensor circuit     Sensor operating outside of the sensors normal operating range or sensor has a fault.     Check temperature sensor for correct operation, check temperature of screed base plate.    
8     short short long short     Left hand main temperature sensor circuit     Sensor operating outside of the sensors normal operating range or sensor has a fault.     Check temperature sensor for correct operation, check temperature of screed base plate.    
9     long short long short     Right hand extender temperature sensor     Sensor operating outside of the sensors normal operating range or sensor has a fault.     Check temperature sensor for correct operation, check temperature of screed base plate.    
10     short long long short     Right hand extender temperature sensor     Sensor operating outside of the sensors normal operating range or sensor has a fault.     Check temperature sensor for correct operation, check temperature of screed base plate.    
( 1 ) For this table, the flash sequence determines the type of error that is present. The red led will flash four times. The term short refers to a half second illumination of the led. The term long refers to a one second illumination of the led.
