Atlas Copco MAS 200, Инструкция

Страница: 84 / 94

• Example:
• Machine = MAS 200 440 V
• The value for F21 = 20.7 %
• I
e
= 20.7 x 10 = 207 A
• 20 mA = ( 20 - 4) x 207 / 12.8 = 258.75 A → Multiply by 1.73 → The supply current =
447.6 A
• 14 mA = ( 14 - 4) x 207 / 12.8 = 161.72 A → Multiply by 1.73 → The supply current =
280.1 A
• 16.8 mA = ( 16.8 - 4) x 207 / 12.8 = 207 A → Multiply by 1.73 → The supply current =
358.5 A
Optional analog output
Electronic overload relay with analog output (expansion module 3RB2985-2AA0, -2AB1 and
-2AA1)
• 4 to 20 mA
• 1 % x I
e
= 0.128 mA.
Example:
• I
out
= 10.40 mA.
• I
e
= 6.0 A.
• I = 50 % of I
e
• I
motor
= 3.0 A.
