Specific Verometer Odorant Inlet Low
Alarm IssuesTroubleshooting Steps
When an active OdorInlet Lo alarm is indicated the
following steps should be taken:
1. Verify that the bulk odorant storage tank pressure
exsits in a range of 30 to 35 psi
(2.07 to 2.41 Bar)
and re-establish the correct pressure if necissary.
2. Inspect the alarm set point programmed into the N-
300 controller and verify that it is correclty pro-
grammed and correct if necessary,
refer to the
parameters section on programming the N-300
controller
Section 5, page 29 or Section 6, page 36
depending on the mode of operation.
3. Observe if the alarm is still active, if it is, contact YZ
Technical Services.

and re-establish the correct pressure if necissary.
2. Inspect the alarm set point programmed into the N-
300 controller and verify that it is correclty pro-

Specific Verometer Expansion Tank
Cable Alarm Issues Troubleshooting
Steps
When an active XTank-Cable alarm is indicated the
following steps should be taken:
1. Inspect all cables for any external damage such as
cuts or crimps in the external cable sleeve or
moisture inside the cable connector.
2. Loosen and inspect the cable orientation pins for
correct positioning. All cables have a specific
mating connection to ensure that the correct pins on
the opposing sides of the connector align. These
pins must be correctly aligned to ensure the elec-
tronic signals reach the correct electronic address in
the microprocessor.
3. Reconnect cables as noted above, ensuring that the
alignment pins are mated correctly and that locking
rings are tight. Observe if the alarm is still active, if it
is, contact YZ Technical Services.
Specific Verometer Expansion Tank
Low Alarm Issues Troubleshooting
Steps
When an active XTank Low alarm is indicated the
following steps should be taken:
1. Verify that the expansion tank pressure is at 25 psi
(1.72 Bar) and correct if necessary.
2. Inspect the alarm set point programmed into the N-
300 controller and verify that it is correclty pro-
grammed and correct if necessary,
refer to the
parameters section on programming the N-300
controller
Section 5, page 29 or Section 6, page 35
depending on the mode of operation.
3. Observe if the alarm is still active, if it is, contact YZ
