waters UPLC液相 泵報錯復(fù)位失敗的原因？
菜鳥博士Caesar
pump h/w home fault（4） 且communication failure
硬件故障的話是泵馬達(dá)的問題。
此外：
故障描述
初始化期間出現(xiàn) Pump H/W Homing Error (3)（泵硬件復(fù)位錯誤 (3)）消息
拆下泵頭后，電機初始化成功
環(huán)境
ACQUITY UPLC H-Class Bio
ACQUITY UPLC H-Class
原因
反壓或物理限制的阻力限制了蓄積泵頭的移動
解決方法
拆下泵頭并確認(rèn)可以自由移動。
清洗柱塞裝置、泵頭和泵彈簧，去除沉淀物堆積。
重新初始化儀器，驗證問題是否已解決。
SYMPTOMS
Pump H/W Homing Error (3) occurs during initialization
Removing pump head brings successful initialization of motor
ENVIRONMENT
ACQUITY UPLC H-Class Bio
ACQUITY UPLC H-Class
CAUSE
Restriction of accumulator pump head movement due to resistance from back pressure or physical restriction
FIX or WORKAROUND
Remove the pump head and confirm free travel.
Clean the plunger assembly, head, and pump springs to remove buildup of precipitates.
Reinitialize the instrument to verify that the issue is resolved.
