Contrec数字键盘批量控制器430D


Contrec 430D

频率输入,数字键盘批量控制器


430D批量控制器适用于需要精确测量和控制可变批量的应用。

该仪器非常灵活且易于操作。可以通过四个操作键启动,暂停,停止和重置批次,批量和校准参数通过12键数字键盘输入。

批量总计,流量,累计总量和预置值都可以在绿色LED显示屏上以工程单位显示。

430D将接受大多数频率和脉冲信号,包括涡轮流量计的mV输出和双线接近开关输出。

批量功能

自动超限补偿基于以前的批次,430D将自动补偿可能由缓慢关闭阀门引起的任何超限。

计算机/打印机接口

RS232和RS422 / 485选件可用于连接计算机和打印机。该接口允许从计算机完全控制批处理控制器。

软件驱动程序包含在许多打印机中,可以打印带有时间和日期的票证,顺序交货/批次编号以及批次和累计总计。还可以打印票证的可选标题。

RATE TOTALISER模式

430D可以在校准期间配置为与批量控制器不同的速率累加器。

在此模式下,RUN,STOP和Batch Set键不起作用。Rate键用于在Rate和Resettable Total之间切换显示。

By pressing and holding the Accum. key, whenever the instrument is not in data entry mode, the Accumulated Total will be displayed.

VERSATILE PERFORMANCE OPTIONS

The instrument will operate from 14 to 28V dc or from 110 to 220V ac mains.

The facia is fully watertight to Nema 4X (IP65) and is resistant to most chemicals.

A total conversion feature enables the rate to be displayed in one engineering unit (eg. gallons/minute) and the totals to be displayed in another engineering unit (eg. barrels).

The standard instrument is supplied as panel mount. Field enclosures are optionally available.

Operation

Keypad operations are straightforward and four LED’s indicate the operational status at all times.

The unique keypad simplifies operation, making the instrument suited to use by operators with minimal training.

Four operational keys and a full numeric keypad on the front facia, enable the batch quantity to be set, and batch operations to be started, paused, stopped or reset.

SETTING BATCH QUANTITY

To set a batch quantity, the Batch Set key is pressed, and then the quantity is entered via the numeric keys. Once set, the Batch Set key is again pressed to return to Run mode.

The batch quantity can only be set while the instrument is in a non- operational state such as when the batch is complete or paused.

Once set, the batch quantity will be retained in non-volatile memory and will not alter until changed by the user.

To check the batch quantity while a batch is in progess press the Batch Set key.

STARTING A BATCH

To start the batch the RUN key is pressed. The Run LED will light and the instrument will begin to totalise from zero or, if programmed for the count down mode, the display will decrement from the batch quantity.

STOPPING A BATCH

The batch can be stopped at any time by pressing the STOP key. To continue the batch press the RUN key, or to abort the batch press the STOP key again.

When the batch has been interrupted the Pause LED will light. If the batch is aborted the Stop LED will light.

RESETTING A BATCH

The instrument can be programmed to reset in either of two ways.

By manually pressing the Reset key, at the end of a batch, the Batch Total will be reset to zero (if programmed to count up) or to the preset quantity (if programmed to count down).

If Auto Reset is programmed, however, the Batch Total will automatically reset when the RUN key is pressed.

一级或两级阀门控制

两个输出继电器为单级或双级阀门操作提供控制。第一个继电器将在批次开始时通电,并在批次完成时断电。

第二个继电器可以编程为在启动后的设定时间通电,并在完成批次之前以设定的数量断电。此功能可实现缓慢启动和缓慢关闭流。

批处理控制器也可以编程为从批量数量的零或向下计数。
