15.5 DIAGNOSTIC INFORMATION 分析诊断信息
The printed circuit board inside the ViscoSense
®
2 controller has a provision for diagnostic indication.
Failures and errors are displayed by a blinking digit or character on a 7 segment LED. Dependent on
the type of failure, error or warning, the viscosity and/or temperature outputs will go to 0, 4 or 20 mA,
or will remain functioning normally. 控制器中的印刷电路板有一个实用的帮助分析诊断失效的规定。
误差和故障通过闪光的数字或者符号在一个7片段发光二极管上显示出来。取决于失效,误差或警报
的形式,粘度和/或温度的输出将会为0,4 或 20mA; 或者保持正常功能。
If there is no failure, error or warning, the display indicates the state of the program by displaying a
symbol (not blinking) on the display. 如果一切正常,显示器上将会显示指示程序状态的(不闪光跳
动)符号。
The following symbols are displayed during normal operation: 正常操作情形下,将会显示下列符
号:
Display 显示 Description 描述 Display 显示 Description 描述
Power on 电源接通
Changing U-send_setpoint
改变电压输出信号设定值
Initializing hardware 硬件初始化
measuring at + 45 degrees
(left -3 dB point)
在相位+45度时测量(左-3 dB点)
VCO frequency measurement while
phase is +45 degrees
压控振荡器在相位+45度时频率测量
measuring at - 45 degrees
(left +3 dB point)
在相位-45度时测量(左+3 dB点)
Waiting for U_receive to settle after
changing setpoint
改变设定值后等待电压信号
Adjusting phase 正在调节相位
The decimal point at the bottom of the display is always on after power is on. This point is only
turned off while the ViscoSense
®
is writing to EEPROM, and if no measurement is possible due to
extensive external vibrations.
电源接通后小数点总是在底部显示。如果由于巨大的外部振动导致无法测量,传感器写入电可擦只读
存储器时它才消失。
Normally the ViscoSense
®
2 electronics will try to restart the unit if a faulty situation occurs. However,
if the fault is persistent contact VAF Instruments or your local authorised VAF dealer and give a
detailed description of the problem that occurred and the diagnostic information indicated at the 7
segment LED.
通常如果发生故障,传感器将会重新启动装置。但是如果故障仍然存在,请及时与VAF或所在地经
VAF授权的销售商联系并提供详尽的问题情况说明以及在7片段发光二极管上显示的帮助诊断资料。
