Fire pump controller water pressure data logger

To open this page push the [F1] button. It indicates the Mode of operation, date & time, engine status and water pressure. 'START DEMAND=ON' means request of start.

This is the DATA LOGGER screen. It automatically updates every 5 minutes and it records MAX, AVG and MIN values on a nonvolatile memory for about 31 days.

In addition to digital inputs, you can configure the analog input for a pressure transmitter. You can set a low limit to start the pump and a high limit to stop the pump.

You can set alarms of water pressure. Every time the pressure rises above or falls below the set points, the Be126 will record the value and date & time in the Event Log.

Be126 accepts transmitters 4-20mA or 0-10V. Full scale should not exceed 30 Bar. You can program any value for point 1 and point 2. In this example a 0-30 Bar sensor. 

The Bypass delay lets Be126 to ignore pressure alarm of short duration.

You can choose here 4-20mA or 10-10V transmitter.

- WATER PRESSURE DATA LOGGER

The Be126 water pressure data logger is available all the time when you program at least a setting in the [WATER PRESSURE] menu; for example a [START DEMAND], [HIGH PRESSURE] or a [LOW PRESSURE] parameter. The Be126 ‘Status Page’ (see section XX) displays the pressure provided by a pressure transmitter connected to the terminal JM-1. The Be126 automatically updates the [WATER (BAR) LOGGER] page page every 5 minutes providing average pressure measurements (P[AVG]), minimum pressure measurements (P[MIN]) and maximum pressure measurements (P[MAX]). The Be126 records as many as 26784 samples equivalent to 31 days of continuous recording. The display is organized in 4 columns that indicate time stamp, P[MIN], P[AVG] and P[MAX].

On the [WATER (BAR) LOGGER] page you can:

- browse the samples one by one (using the [SLOW UP/DOWN] mode).

- browse the samples by days (using the [FAST UP/DOWN] mode).

- locally download the data using the RS232 interface (you are required to enter the OFF mode of operation and to use our software for downloading the PRESSURE.CSV file).

- remotely downloads, at any time and in any mode of operation, the data via the RS485 serial interface. We recommend that you use our software for remote monitoring).

- set up a Low Pressure peak detect mode (the display shows only samples lower than P[AVG] - P[PK])  -[*]- .

- set up a High Pressure peak detect mode (the display shows only samples higher than P[AVG] + P[PK])  -[*]- .

 To access the [WATER (BAR) LOGGER] page, push the [MENU] button to open the Main Menu. Repeatedly push the [ ↓ ] arrow to reach the end of the Main Menu. When you find the [WATER (BAR) LOGGER] menu, push the [→] arrow to enter the menu. The Be126 will open the following page.

-[*]- Note: you can set up the P[PK] by programming the parameter [PEAK DETECT] (see the [WATER PRESSURE] menu, section xx)

A) - The first line of the display indicates the day, month and year. The column on the left indicates hours:minutes. Then, the display indicates the column of the minimum recorded values, the average recorded values and the maximum recorded values. Please note that if you set a filter on the peak detect, the display will not indicate a value. Example: setting up a Peak Detect of 0.5 bar. As you can see, on the left side, the Max value at 9:50 is missing and Min value is missing at 9:55. This is because no Max or Min values exceeding 8.0 BAR +/- 05 BAR have been detected.

 

 

 

 

 

 

 

 

B) - Push the [→] button to choose the fast mode. In this way, by using the [ ↑ ] or

 [ ↓ ] arrows you can easily select a day of the last 31 recorded days.

 

 

 

 

 

 

C) - Push the [→] button to choose the slow mode. In this way, by using the [ ↑ ] or [ ↓ ] arrows you can browse the 288 samples, one every 5 minutes, (864 if you include Max & Min) of a chosen day.

 

 

 

 

 

 

You can download the water pressure data logger data at any time in any mode of operation by using our software for control and monitoring via the RS485 serial interface. As an option, you can download the data manually by using a laptop. Follow the instructions.
