7. Operational Check &Leak Testing
7.1 When all of the tubing connections have been com-
pleted, close the purge valve on the front of the sampler
probe body. Open the sample probe supply valve to allow
pipeline pressure into the sampler. Check all connections
using a liquid leak detector.
7.2 Adjust the filter/regulator from the following ranges:
Pipeline Pressure
Under 700 psig (48 Bar)
Over 700 psig (48 Bar)
7.3 Turn the stroke adjustment knob on the top of the pump
counterclockwise to set the pump displacement at .4 cc/
stroke.
7.4 Set the mode switch to position #5.
7.5 Set the data switches to 00.0 to enter the diagnostic
mode of operation.
7.6 Depress the enter switch to load the value into memory.
7.7 Pump actuation will begin as the solenoid valve is
energized by the Z-200. In this mode, pump actuation
should occur every two seconds.
7.8 Each time the solenoid actuates, the LCD stroke
indicator on the Z-200 should increment.
7.9 Allow the sampler to operate until the desired stabilized
pressure is achieved at the sample discharge.
7.10 Return the mode switch to position 9 (off position).
7.11 Check all connections from the sampler discharge to
the connection on the sample cylinder and the connection
from the pump to the manifold at the discharge tubing using
a liquid leak detector.
7.12 If no leaks are found, the pump and tubing should be
considered tested and functional.
Actuation Pressure
50 psig (3.5 Bar)
65 psig (4.5 Bar)
