?校準模式啟用必須設置為禁用，<S11>=0。
?LVDT狀態(tài)必須良好。要執(zhí)行空檢查：
1.轉(zhuǎn)到S7中指定的塊地址。將LVDT設置為空將主LVDT變壓器的模式檢查為1。
2.轉(zhuǎn)到S11中指定的塊地址。設置校準模式啟用為1。這將IMHSS03模塊置于校準模式。
3.轉(zhuǎn)到S12中指定的塊地址。設置通過/保持選擇至1（GO）。
4、等待所選LVDT變壓器處于零位標志在塊輸出N+7位7中設置。

6.如果有冗余LVDT變壓器，請轉(zhuǎn)至模塊S7中規(guī)定的地址。將LVDT null check mode設置為2備用LVDT變壓器。
7.重復步驟4和5。
8.調(diào)整完成后，設置GO/HOLD select將校準模式啟用設置為0（保持），然后將校準模式啟用設置為0（禁用）將null check設置為0（禁用）。自動調(diào)諧（功能代碼55）要開始自動調(diào)諧，MFP模塊必須與IMHSS03模塊通信，并滿足以下條件必須滿足：?渦輪機離線。?伺服閥或I/H轉(zhuǎn)換器（用于渦輪機液壓系統(tǒng)）必須處于控制位置并正常工作正確地

Calibrate mode enable must be set to disable, <S11> = 0.
?
LVDT status must be good.
To perform the null check:
1. Go to the block address specified in S7. Set the LVDT null
check mode to 1 for the primary LVDT transformer.
2. Go to the block address specified in S11. Set the calibrate
mode enable to 1. This places the IMHSS03 module into cali
brate mode.
3. Go to the block address specified in S12. Set the GO/HOLD
select to 1 (GO).
4. Wait until the selected LVDT transformer at null point flag
is set in block output N+7, bit 7.
5. Make the necessary adjustments to the servo valve and the
LVDT position to adjust the actuator to its mechanical null
position. For maximum LVDT linearity, the LVDT null point
should occur at the actuator’s midtravel position. When S12 is
in the GO mode, the actuator ramps to and holds at the LVDT
null point (LVDT secondaries have equal voltages). While the
actuator is held at the LVDT null point, the mechanical zero on
the LVDT transformer can be adjusted until the actuator is at
its midpoint position.
6. If there are redundant LVDT transformers, go to the block
address specified in S7. Set the LVDT null check mode to 2 for
the backup LVDT transformer.
7. Repeat Steps 4 and 5.
8. When the adjustments are complete, set GO/HOLD select
to a 0 (HOLD), set calibrate mode enable to a 0 (DISABLE) and
set null check to 0 (DISABLE).
AUTOMATIC TUNING (FUNCTION CODE 55)
To start automatic tuning, the MFP module must be communi
cating with the IMHSS03 module and the following conditions
must be met:
?
The turbine is off-line.
?
The servo valve or I/H converter (for turbine hydraulic sys
tem) must be in the controlling position and functioning
properly.
?
The multi-function processor module has function code 55
in its configuration.
