sc1000通用控制器常用问题

 

.  sc1000 可以接多少个1720E探头?

. 由于1720E 电耗较高, *多只能接2个1720E探头,如果超过2个探头,需要另配sc1000探头模块。sc_1000通用控制器

 

问.     HACH任何数字化探头都可以和sc100、sc1000连接使用吗?

答. 是的。Any digital sensor has true plug and play capability with any sc100 and sc1000 controller. That means that you simply plug in the sensor and it will work without any intervention. Calibration may be required for certain parameters.

 

问.     两个不同参数的探头可以共用*个sc100或sc1000通用控制器吗(比如PH&DO)?

答.     可以的, the sc100 will take any combination of two probes from the Hach Digital Family. The sc1000 will take several of them.

 

问.     *sc1000的系统中可以同时接第二个显示模块吗?

答.     不可以。 

 

问.     sc1000目前可以提供什么方式的通讯卡?

答.      目前可以提供 MODBUS RS485 和Profibus DP 。sc1000不可以支持HACH的 LonWorks 卡 (连接1720E 到AquaTrend 网络系统);注意乙太的服务接口不是现场通讯用的乙太接口,它只对单独PC连接。 

Q. Can an sc-sensor be hard-wired to the sc1000?

A. Unlike the sc100, the sc1000 does not have internal terminal strips that would allow a sensor to be wired directly to it (without the sc connector).

 

.     sc1000的模拟信号卡可以为2线制的变送器供电吗?

.     不可以。必须单独提供电源;输入卡只能接受4-20mA信号。 

 

.     可以单独订购没有遮阳罩的控制器按照支架吗?

.     可以。Yes. 整套安装支架订货号:LZX958,无遮阳罩安装支架订货号:LZY001。 

Q. What is the “digital” capability of the sc1000 Analog/Digital Input card?

A. The Input card can accept either analog (0 or 4 to 20 mA) or digital inputs. Digital means a simple on/off type input. An example would be the output from an external relay. This allows the user to combine an external status (tank full or empty for instance) with the other readings available on the sc1000).

 

Q. What is the delivery lead-time for the sc1000?

A. As the sc1000 is a complex product family with many possible variations, it is not possible to keep all potential variations in stock. The Display Module, two versions of the Probe Module, and key spare parts and accessories will be kept in stock in Ames with a standard lead-time of 5 days. Other variations of the Probe Module will be built to order in Germany with a standard lead-time of 25 days. If you require delivery faster than provided by the 25-day lead-time, you must order one of the stocked units and adapt it according to your customer’s needs. To do this, you must add or remove components (typically boards for relays, analog inputs or outputs, field-bus boards, sc-sensor connectors) as necessary. This is easily done by a qualified electrician and does not void the warranty.
