ecom-DP3
6.3. 4Pa measurement (option)
The simultaneous operation of room-dependent firing place and air evacuation
system can lead to dangerous low pressure conditions. With the
ecom-DP3
it is
possible to check the low pressure limit value of 4 Pa and to document in a dia-
gramme the time course of the low pressure value. Once the menu point is called
up, the measurement is to be performed as follows:
- connect capillary hose for room where burner is installed to
„-“
- connect capillary hose for reference place (staircase or outside air to
„+“
- operate firing and evacuation systems with maximal performance
- open window resp. connection door to burner room and check the correct
evacuation of the exhaust gases
- zero pressure sensor with
<F4>
- position capillary hose for reference location
- start record pressure value course with
<F1>
(Start) (an acoustical signal is
issued every 30 sec. which can be deactivated / re-activated by pressing
<F2>
)
- record pressure by opened window resp. connection door
- close window resp. connection door after approx. 30 sec. and check low
pressure
- after approx. 30 sec. open window resp. connection door and check zero point
- close window resp. connection door after approx. 30 sec. and check low
pressure
- after approx. 30 sec. re-open window or connection door and check zero point
- after approx. 30 sec. close window resp. connection door and check low
pressure
Once the measurement time is completed, the diagramme can be viewed on the
display (use
<F3>
to emphasize illustration 1x, 2x, 4x, 8x times or A for automat-
ic). Start a printout if needed with
<Print>
