Symptom
Possible Cause
Corrective Action
19)High or low pressure alarm
activated when digital display
indicates pressure or vacuum
is within normal limits.
a. Alarm set-points have been
changed.
b. Faulty digital display module.
a. Use digital display module test
mode (Page 117) to check
current set-points. If incorrect,
reprogram low and/or high

display does not match
pressure or vacuum levels in
pipeline.
a. Incorrect digital display “unit of
measure”.
b. Faulty digital display module.
c. Faulty sensor module.
a. Use digital display module test
mode (Page 117) to check
current unit of measure (PSI,
in Hg, kPa, mm Hg). If
incorrect, reprogram unit of
measure. Refer to
Set-Up
instructions (Page 64).
b. If alarm panel contains another
working digital display module,
remove field wiring connector
from suspect module and
connect to working (test)
module. Temporarily program
gas id, and units to match the
sensor module. If test module
provides correct reading,
replace faulty digital display
module.
c. If test module in step b above
also gives incorrect display,
replace faulty sensor module.
21)Low alarm with
-- FF 22 --
display
on digital display module.
Pressure or vacuum signal to
digital display module out of
measurement range (too low)
as a result of:
a. No pressure or vacuum in
pipeline.
b. Faulty digital display module.
c. Faulty sensor module.
a. Apply appropriate pressure or
vacuum to pipeline.
b. If alarm panel contains another
working digital display module,
remove field wiring connector
from suspect module and
connect to working (test)
module. Temporarily program
gas id, and units to match the
sensor module. If test module
provides any reading other than
-- FF 22 --
, replace faulty digital
display module.
c. If test module in step b above
also gives
-- FF 22 --
, replace faulty
