buffer overflow
Remedial action
• Check the mains voltage
• If the mains voltage is OK,
replace the control
• Check mains voltage,
if nominal voltage is
continuously exceeded:
stabilize it or use a generator
• Check the mains voltage
• Stabilize the mains voltage
• Use generator
• Disconnect 37-pin plug; if error
persists: Replace the control
• Test inputs/outputs for 24 V
