EHG SL10 Error Codes
Display Description Possible Cause Corrective Action
[SL1] Limit error Sensor has exceeded SLA value or
open thermocouple • Set SLA to correct Safety
Limit Value
• Check wiring of sensor
• Check sensor confi guration
[SL2] Control error Sensor has exceeded SLA value or
open thermocouple • Set SLA to correct Safety
Limit Value
• Check wiring of sensor
• Check sensor confi guration
[Er3] Limit Sensor Error Limit sensor reading out of range (<
-13 or > 640) • Check wiring of sensor
• Check sensor confi guration
[Er4] Control Sensor Error Control sensor reading out of range
(<-13 or > 640) • Check wiring of sensor
• Check sensor confi guration
[Er5] Limit Ambient Error Temperature at limit sensor cold junc-
tion (> 185 degrees) • Check to be certain the EHG
SL10 is not in an ambient
condition greater than 185
degrees C
[Er6] Control Ambient Error Temperature at control cold junction
(> 185 degrees) • Check to be certain the EHG
SL10 is not in an ambient
condition greater than 185
degrees C
[ER9] HMI Communications
Fault Loss of communication between base
and display communications module • Check connection between
EHG SL10 and display/com-
munications module
[Ahi] Alarm High Process temp exceeds set point by
value greater than alarm high setting • Set HTA value to correct high
temperature alert value
[Alo] Alarm Low Process temp below set point by value
greater than alarm low setting • Set LTA value to correct Low
temperature alert value
