ALARM WORD 1
- 1 0000 hex
Read-only copy of the ALARM WORD 1.
• When a fault is active, the corresponding bit for the active fault is set in the Fault
words.
• Each fault has a dedicated bit allocated within Fault words.
• Bits remain set until the whole alarm word is reset. (Reset by writing zero to the
word).
• The control panel displays the word in hex. For example, all zeros and a 1 in Bit 0
correspond to 0001. All zeros and a 1 in Bit 15 correspond to 80000.

ALARM WORD 2
- 1 0000 hex
Read-only copy of the ALARM WORD 3.
• See parameter 0308 ALARM WORD 1.
