Section 19.0.1

 

START DEMAND               

                          OFF

STOP DEMAND

                         OFF

 

(range: 0.1-30.0 BAR)

When the water pressure drops below the [START DEMAND] pressure setting, the Be126 initiates the start sequence. The display turns on the message [START DEMAND ON]. When the pressure rises above the [STOP DEMAND] pressure setting, the Be126 initiates the stop sequence. You can delay, or bypass, the start and stop by programming the [START DELAY]  and [STOP DELAY] timers (see [MISCELLANEOUS]). If you set the [STOP DELAY] to [OFF], the Be126 will not automatically stop the engine.

 

 

Section 19.0.2

 

HIGH PRESSURE                       

                           15 sec

LOW PRESSURE

                             6

 

(range: 0.1-30.0 BAR)

When the water pressure drops below the [LOW PRESSURE] pressure setting, the Be126 turns on the low water pressure alarm.  When the pressure rises above the [HIGH PRESSURE] pressure setting, the Be126 turns on the high water pressure alarm. The alarms are recorded in the Memory Events Register. You can bypass the alarms for a programmable time by setting up the [BYPASS DELAY] timer (see next).

 

 

Section 19.0.3

 

BYPASS DELAY                     

                      8.0 VDC

TRANSMITTER

                    4-20mA

 

(0-59 secs; options for

4-20mA or 0-10VDC)

 

 

You can bypass the High/Low water pressure alarms by setting up the [BYPASS DELAY] timer.

 

The [TRANSMITTER] parameter allows you to select a 4-20mA transmitter or a 0-10V transmitter. You can also set up the full scale of the transmitter (see next).

 

 

Section 19.0.4

 

POINT 4 mA                     

                      0.0 BAR

POINT 20 mA

                     30.0 BAR

 

(0.0-30.0 BAR)

You are allowed to program 2 points for configuring the response curve of the transmitter. You are required to program the start point (at 4mA or 0VDC) and the full scale (at 20mA or 10 VDC). You have to connect the transmitter to terminal JM-1. In case you configure the 4-20Ma option, the Be126 will trigger the alarm [SENSOR FAILURE] when the circuit is open.
