调整设定点数值操作-中英对照
警告
您可以在发动机或者其它设备正运行时调整设定点。不过, 如果您调整的继电器设定值比当前运行的速度低时,继电器将跳闸;
在该步骤中您需要一个0-1 mA测量仪表。如果测量仪表由速度开关供电,您可以使用;否则,您必须使用一DPM-105测量仪表或者任何0-1个mA电表;
外部测量仪表应该进行校验:SST-2000A-/H的"0-1 mA = 0 量程输入频"。
参见量程频率值和装置说明书或序号标签。
1 观察极性。将一外部0-1 mA测量仪表和终端7(-)和 8(+)连结起来
2. 根据设备调整的设定值,从下列部位连结临时跨接线:
终端16-12(设定点1)或者
终端16-13(设定点2)或者
终端16-14(设定点3)或者
终端16-15(设定点4)
3. 0-1 mA 测量仪表现在将注明选择设定点的电流值( 参阅图 4-14,第31 页)。
4. 如有必要,使用第28 页的程序目录调整个别给定值,首先调整选择设定点。
5. 移除临时跨接线。
6. 终端7和8的输出能再次提供标准0-1mA比例输出。
7. 其它的给定值重复第1-5步骤

Adjusting Set Point Values
WARNING
You can adjust set points while the engine or other device is operating. However, if you adjust a set point relay to a value lower than the current operating speed, the relay will trip.
You will need a 0-1 mA meter for this procedure. If a meter was supplied with the speed switch, you can use it. Otherwise, you can use a DPM-105 meter, or any 0-1 mA ammeter.
The external meter should be calibrated : "0-1 mA = 0 to full-scale input frequency" of the SST-2000A/H.
See the specification sheet or serial number label that accompanied the unit for the full-scale frequency value.
1 Observe polarity. Connect an external 0-1 mA meter to terminals
2 Depending on the set point to be adjusted, connect a temporary
jumper from :
» Terminal 16 to 12 (for Set point 1) or
» Terminal 16 to 13 (for Set point 2) or
» Terminal 16 to 14 (for Set point 3) or
» Terminal 16 to 15 (for Set point 4)
3 The 0-1 mA meter will now indicate the current value for the chosen
set point (see Fig. 4-14, page 31).
4 If necessary, first adjust the selected set point using procedures
outlined in Adjusting Individual set points, page 28.
5 Remove the temporary jumper.
6 The output from terminals 7 & 8 will again provided the standard
0-1 mA proportional output.
7 Repeat steps 1-5 for additional set points.
