SYMPTOM
CAUSE
REMEDY
LOW VOLTAGE CRITICAL
Apparatus Charging Sys-
tem
Check system voltage with multime-
ter:
If voltage is low, troubleshoot and re-
pair apparatus charging system.
If voltage is fine, perform Voltage
Calibration (see paragraph 5.6,
page 184)
Equipment Failure
SAM Pump Controller (analog to digi-
tal conversion circuit failed) See par-
LOW VOLTAGE WARNING
Apparatus Charging Sys-
tem
Check system voltage with multime-
ter.
If voltage is low, troubleshoot and re-
pair apparatus charging system.
If voltage is fine, perform Voltage
Calibration (see paragraph 5.6,
page 184)
Wire Harness Damaged
Check harness power connections
and circuit breakers. See para-
graph 4.3.5 (page 48) and sec-
Equipment Failure
SAM Pump Controller (analog to digi-
tal conversion circuit failed) See par-
POSSIBLE CAVITATION
During drafting, SAM de-
tected cavitation
(SAM detected an in-
crease in rpm and no
change in discharge pres-
sure and/or flow. The
pump is not receiving
enough intake water flow
for the desired discharge
condition.)
Check suction hose/seals for leaks.
Replace suction hose with a larger
size and/or increase number of suc-
tion lines available on the apparatus.
During pumping from
tank, SAM detected cavi-
tation
Perform Water Tank-to-Pump Flow
Test (per NFPA 1901). Repair appa-
ratus as required.
During pumping from hy-
drant, SAM detected cavi-
tation
Check LDH/seals for leaks.
Verify SAM Bypass Venting functions
POSSIBLE VACUUM LEAK
(SAM Detected A Continued Decrease
In Suction Line Vacuum.)
Equipment Failure
Check LDH/seals for leaks and
hoses for leaks and/or restrictions.
Perform NFPA pump vacuum test.
