Dead-end Pipes Purging Application Settings
Due to operational conditions, in some municipal and industrial
water systems, there is a need for periodic purging of the
systems dead-ends of pipes for refreshing the water supply.
BERMAD’s control valves equipped with Subtv controllers can be
installed in these systems. BERMAD’s Dead-end Pipes Purging
Application accounts for the purging out of the system. This task
is automatically performed based on three major parameters:
1. Purging interval - set at specific days of the week or as
day’s interval
2. Amount of purged water - set by operation time or by volume
3. Start time - set for the operation day (with up to three start
times per such day)
The following examples depict three typical scenarios:
A. Purging interval by Days of the Week and purging
amount by operation time:
In this example the pipe needs to be purged for 5 minutes every
Monday and Friday at 08:00 AM. Therefore, the three required
program parameters of the controller are: Operation Time - 5
Minutes, Operation Days - Monday and Friday, and Start Time
at 08:00 AM.
1. Operation Time:
Use the
button to move to the Operation Time programming
screen - this is the screen with blinking
icon, blinking triangle
with the digit 1 in it and the
icon. Use the
and the
buttons to set the required operation time (00:05 minutes in
our example).
Press the
button to move to the next programming screen
which is the Operation Days screen.
