ENCLOSURE
OPEN Indicator:
This indicator (4) illuminates when the burst enclosure
lid is open. Testing can not start until lid is closed. If lid
is opened during a test, testing will stop. Opening the lid
during a test has the same effect as pressing the
STOP
TEST
button. The lid must be closed and the test
restarted to resume testing that specimen.
START TEST
Button and
Indicator:
Once a specimen is properly installed and filled, start a
test by pressing this button (5). The indicator will
illuminate to show that pressure is being increased to the
specimen. Once the starting pressure is reached, the
timer will begin counting. Pressure will be supplied to
the specimen at the rate defined in the Eurotherm
controller. If test will not start, check that
STOP TEST
button is disengaged and that the burst enclosure lid is
closed.
STOP TEST Button:
Any test can be stopped immediately by pressing this
button (6). When the
STOP TEST
button is pressed: the
supply valve closes; the drain valve opens; and the
current program is cancelled (setpoint goes to zero).
Once the specimen pressure falls below the start pressure
(75 psi), the timer stops counting. The button must be
disengaged (pulled out) before testing can be restarted.
SPECIMEN FILL
Valve:
This valve (7) allows the burst supply system to fill the
test specimen with low pressure water before
pressurizing. Open the specimen’s purge valve to bleed
air from the specimen and then open the fill valve to fill
the specimen. Close the fill valve when water flows from
the purge valve. Close the purge valve. A check valve
prevents high pressure feed back to the water inlet of the
pump should the fill valve be left open after filling the
specimens.
SPECIMEN Dial:
If the multiple specimen option was purchased, the burst
system will be equipped with a
SPECIMEN
dial that
permits an operator to select which specimen will be
tested when the
START TEST
button is pressed.
