Crowcon Gas-Pro - Pump test

2.3 Pump test
In the default conguration, a pumped Gas-Pro with a ow plate attached (see Fitting a ow plate on
page 12) will run a pump test during the start up process. A pump test will also be run whenever a
ow plate is attached during normal operation.
i
If the Gas-Pro is congured for Bump functionality, the Bump/Pump prompt will be
displayed if a ow plate is attached and a gas bump test is due or the Gas-Pro is placed in
a Q-Test module during normal use (see Bump/Pump functionality on page 33).
i
Prior to tting, the ow plate’s gasket should be checked for any damage.
The pump test ensures accurate sealing as well as monitoring pump performance.
The user will need to cover the pump inlet
À (see Figure 13 below) when prompted to do so by the
symbol on the screen.

When the test has nished, the pump will either pass
or fail .
If the pump test takes place during start-up and the Gas-Pro passes, the pump will remain on and
the start-up process will continue as normal. If the test is passed during normal use, the Gas-Pro will
remain in the pumped mode until the ow plate is removed.
On failing the pump test the fail screen will persist with an audible alert until the button is pressed
and the test repeats OR the ow plate is removed and the Gas-Pro returns to unpumped operation.
For further detail on failing a pump test see Pump test failure on page 48.
