Lifetime Diagnosis for Fans
A fan exchange warning can be provided by entering a percentage at Pr.87 (Fan exchange warning
level). The % is based on 50,000 hours of operation. A fan exchange warning will appear on the
keypad or as a relay output when either Relay1 or Relay2 (OU.31 or OU.33) are set to 37 (FAN
Exchange).
The total fan usage level (%) appears at Pr.86. After exchanging fans, you can initialize the
accumulated % to 0 by setting Pr.88 (Fan reset time) to 1 (Yes). The Fan status bit can be viewed at
Pr.89.
