b、 同样监测C3功率段
通过安装在非隔离热量上的电隔离PTC热敏电阻探测器
通过一个
适配器板和隔离盘。评估
电阻和保护效果与上述第（a）点所述一致。
c、 尺寸为C4的功率段不由电隔离PTC热敏电阻直接监控
探测器对于这种尺寸，同样的热敏电阻探测器用于上述（a）和（b），但它
不是安装在散热器上，而是安装在
上部进气区中的机组外壳。这个
探测器因此测量功率段

ASIC功能
ASIC=专用集成电路
大多数测量和控制功能
DCS500在ASIC中完成：
-与控制面板通信（RS 485）
-与励磁机通信（RS 485）
-测量
-看门狗功能
-A/D和D/A转换控制
-晶闸管触发脉冲产生
看门狗功能
控制板有一个内部看门狗。这个
看门狗控制控制板的运行
程序如果看门狗跳闸，则有以下情况
影响：
-FPROM编程电压过低。
-晶闸管点火控制复位并禁用。
-数字输出被强制降低。
-可编程模拟输出重置为
零，0V。Memory circuits and the back-up
The program including system and parameter values is stored at Flash PROMs D33 and D34. Different programs can be downloaded directly to these
PROMs. Application functionallity and parameter
values are saved in the Flash PROM D35.
Fault and Alarm messages are stored in static
RAM circuits. They have a back up capacitor of 1
F, which lasts minimum 8 hours, typically several
days. It takes about 30 minutes to charge the
backup capacitor.
ASIC function
ASIC = Application Specific Integrated Circuit
Most of the measurements and control functions for
the DCS500 are done in the ASIC:
- communication with control panel (RS 485)
- communication with field exciters (RS 485)
- measurement
- watchdog function
- A/D and D/A-conversion control
- thyristor firing pulse generation
Watchdog function
The control board has an internal watchdog. The
watchdog controls the running of the control board
program. If the watchdog trips, it has the following
effects:
- FPROM programming voltage is forced low.
- Thyristor firing control is reset and disabled.
- Digital outputs are forced low.
- Programmable analogue outputs are reset to
zero, 0V.
detector is used as for (a.) and (b.) above, but it
is here not mounted on a heat sink but at the
unit’s housing in the upper intake air zone. The
detector thus measures the power section’s
radiated heat and any changes in the cooling air
temperature and volume. Since the cooling air
volume can only be detected indirectly, a differential-pressure switch has been additionally fitted
at the unit’s housing.
The resistance change proportional to the
temperature is acquired and evaluated in the
unit’s software. If the temperature rises above the
parameterized value, then first an alarm will be
outputted, and - if the temperature continues to
rise - an error message. The value to be set for
this parameter must not be more than 10 degrees above the permissible ambient temperature.
The differential-pressure switch compares the
pressure inside the unit with the normal atmospheric pressure. If the fan has been switched on
and the unit door closed (and no unit casings
have been removed), the pressure switch will
signal “Cooling conditions ok”, which means the
drive may be enabled. There is no need to set
any specific differential pressure (recommendation: centre setting).a.The power sections of sizes C1 and C2 are
monitored by an electrically isolated PTC thermistor detector, which is installed on the likewise
electrically isolated heat sink near the thyristors.
The resistance change proportional to the
temperature is acquired and evaluated in the
unit’s software. If the temperature rises above a
certain value predefined by the unit coding
involved, then first an alarm will be outputted,
and - if the temperature continues to rise - an
error message. This means that changes in the
rated cooling conditions, such as cooling air
volume and temperature, the fan itself, overload
due to an excessively high load current, etc. are
detected.
b.The size-C3 power section is likewise monitored
by an electrically isolated PTC thermistor detector, which is installed on the non-isolated heat
sink in an isolated configuration by means of an
adaptor plate
