3BSE042234R1控制觸摸屏,3BSE042234R1使用進(jìn)展
驗(yàn)證S8中指定的塊地址是否包含正確的校準(zhǔn)沖程時(shí)間。以秒為單位選擇值。在線調(diào)諧不建議校準(zhǔn)行程時(shí)間低于30秒。
3.轉(zhuǎn)到S11中指定的塊地址。設(shè)置校準(zhǔn)模式啟用為1，<S11>=1。這將HSS模塊置于校準(zhǔn)模式。
4.轉(zhuǎn)到S12中指定的塊地址。設(shè)置通過/保持選擇至1（GO）。
5.HSS模塊將致動器驅(qū)動至100%位置
3BSE042234R1控制觸摸屏在<S8>中指定的選定沖程時(shí)間。當(dāng)致動器保持在100%行程末端時(shí)，LVDT差速器記錄100%時(shí)的電壓。If冗余LVDT變壓器則將記錄100%電壓兩個LVDT變壓器。
記錄100%讀數(shù)后，HSS模塊驅(qū)動執(zhí)行器在選定的沖程時(shí)間處于0%位置。雖然致動器緊靠0%行程終點(diǎn)止動塊LVDT記錄0%時(shí)的差分電壓。如果配置了冗余LVDT變壓器，則將記錄0%時(shí)的電壓對于兩個LVDT變壓器。注：位置反饋輸出塊N將顯示電流一次LVDT變壓器讀取的閥門位置。
Verify that the block address specified in S8 contains the
proper calibration stroke time. Values are selected in seconds.
Calibration stroke times under 30 seconds are not recom
mended for on-line tuning.
3. Go to the block address specified in S11. Set the calibrate
mode enable to 1, <S11> = 1. This places the HSS module into
calibrate mode.
4. Go to the block address specified in S12. Set the GO/HOLD
select to 1 (GO).
5. The HSS module drives the actuator to the 100% position
at the selected stroke time specified in <S8>. While the actua
tor is held against the 100% end of travel, the LVDT differential
voltage at 100% is recorded. If redundant LVDT transformers
are configured, then the voltage at 100% will be recorded for
both LVDT transformers.
After recording the 100% reading, the HSS module drives the
actuator to the 0% position at the selected stroke time. While
the actuator is held against the 0% end of travel stop, the LVDT
differential voltage at 0% is recorded. If redundant LVDT trans
formers are configured, then the voltage at 0% will be recorded
for both LVDT transformers.
NOTE: The position feedback output block N will display the current
valve position read by the primary LVDT transformer.
