ERC 113 refrigeration controller
Probable cause
Waiting for compressor delay timer
Defrost in progress
Line voltage to compressor too low
or too high
Door is open or door contact is defective
Controller in pull down mode
Alarm delayed
Ambient light sensor broken
Ambient light sensor broken
or light level not set properly
Condenser too hot
Temperature too high
Temperature too low
Defrost in progress
Automatic Outputs
clearance
User configured Blink "Hi" with the highest temperature; If configured:
cut in alarm relay, beep the buzzer
User configured Blink "Lo" with the lowest temperature. If configured:
cut in alarm relay, beep the buzzer
User configured Blink "Con". If configured: cut in alarm relay, beep the buzzer
Always Blink "dor". If configured: cut in alarm relay, beep the buzzer
Always Blink "uHi". If configured: cut in alarm relay, beep the buzzer

Remedy
Check CoP->CSt
Check CoP ->Pot /Pod
Check dEF ->dit, dot
Check CoP->uLi, uLo, uHi
Fan stops when door is opened
Check that door contact is ok
Defrost might be delayed during pull down
Check parameter Pud->Pdi
Check ALA->Htd, Abd
Check Pud->Pdd
Replace sensor
Check Eng->SLd, SLn
Clean condenser
Check Con ->CAL, CbL
Check ALA->HAt
Check ALA -> LAt
Check diS ->SdF
