3BSE029380R0101 Rev C 6-7
6.8 Warnings and Errors Detected by the Tension Electronics
6.8.1 Errors
6.8.1.1 Flash Memory Error
• Replace PFEA111/112.
6.8.1.2 EEPROM Memory Error
• Replace PFEA111/112.
6.8.1.3 Supply Error
IP 20-version (unsealed):
When the PFEA111/112 is connected to the 24 VDC power supply the voltage between
terminals X1:1 and X1:2 should be 18 - 36 V.
• If the voltage is lower than 18 V:
– Check the power supplies rating. Rating should be 18-36 V DC.
– Check that the power supply has sufficient capacity. See power requirements in
Section 2.8.2 Power Supply Unit SD83x.
• If the power supply has sufficient capacity, check cabling and cable resistance between
power supply and PFEA111/112.
• If power supply and cabling are correct, the tension electronics is probably defect.
Replace PFEA111/112.
IP 65-version (NEMA 4):
• Check the mains voltage connected to terminals X9:1 and X9:2.
Mains voltage must be:
85 - 264 V AC (100 V -15% to 240 V +10%)
Frequency range: 45 - 65 Hz
