Test & Standby Keys
The Test key,
figure 26,
is located in the upper right
quadrant of the N-300G touch pad and is used to
manually stroke the pump. Simply press the test key
touch pad to stroke the pump. Each time the test key
is pushed, the pump should actuate and the N-300G
display will show
Strk
just above the
Test
key touch
pad. The strokes signaled counter will advance for
each stroke of the pump. The odorant injected counter
will also advance when the pump displaces a suffi-
cient volume of odorant to register .001 lb (.001 kg) of
odorant.
The Standby key,
,
figure 26,
allows the operator to
locally inhibit the operation of the N-300G controller.
This creates a standby mode for the NJEX system.
In the event of a no flow condition in the pipeline, the
operator can switch the NJEX to a standby mode for
extended periods of time, or to temporarily suspend
operation of the system for maintenance. When flow
is initiated once more, or the maintenance has been
completed, the NJEX can be switched from standby
to operation without the need to restart the N-300G
controller.
Remote Inhibit Mode,
can also be applied to interrupt
odorization in a manner similar to the standby mode
however, it is initiated by applying a dry contact, or
open collector signal, to the termination board TB1,
terminals #9 and #10 ,

The
Remote Inhibit Mode’s
function is identi-
cal to the
Standby Mode
. Activation will be indicated
on the N-300G display and the Sentry4 event file
differently.

will appear on the N-300 main
screen display where the count down time normally
appears,
