BMS ERROR MESSAGE /
SHUTDOWN
ERROR SOURCE /
DESCRIPTION
CORRECTIVE ACTION
11
Flame 2 Failed During
Relite
Pilot 2 failed to ignite within all
preset relite attempts.
Verify thermocouple condition with mV source or T/C calibrator. If T/C
is faulty, replace with new one. If T/C is in good condition, check the
position of the T/C in the pilot head to ensure it is getting good exposure
to flame. Also, ensure pilot assembly is correctly installed and aligned
with main burner. Verify spark plug is producing strong spark. If spark
plug is faulty, replace with new one.
12
Flame 2 Off
or
Flame 2 Failed to Ignite
Contact Type flame detection
on pilot 2 failed to confirm
flame within Trial for Ignition
Timer value.
Check wiring of Ignition Module or Flame Scanner back to BMS at TS1 #1-
2. Refer to Model 900 or 550 manual for Ignition Module to BMS wiring
schematic. If wiring is OK, check condition of pilot ignition module
for burner #1 or 3rd party flame sensing equipment (Flame Scanner).
Also check condition and installation of all pilot assembly equipment.
Replace any faulty piece of equipment as required. Contact Combustex if
problems persist.
13
Flame 2 T/C Failed
Pilot 2 Flame T/C sensor
indicates OPEN thermocouple
state.
Message indicates open/faulty thermocouple on T/C input TS6 #3-4.
Check wiring of thermocouple to BMS and ensure wires are securely
and properly terminated. Check T/C condition with mV meter or T/C
calibrator. If T/C is faulty, replace with new one. If wiring and T/C are OK,
disconnect T/C and jumper terminals. If S/D is still active with terminal
jumpered, contact Combustex for replacment of T/C modules.
14
High Fuel Press. 1
Gas supply signal for Main
Burner 1 indicating high input
fuel pressure.
(BMS TS4 #5-6)
Check wiring of High Fuel Pressure Switch. If wiring is OK, check High
Fuel Pressure sensor. Replace sensor if faulty. If problem persists,
perform
DI Test 01
.
15
High Fuel Press. 2
Gas supply signal for Main
Burner 2 indicating high input
fuel pressure.
(BMS TS4 #1-2)
Check wiring of High Fuel Pressure Switch. If wiring is OK, check High
Fuel Pressure sensor. Replace sensor if faulty. If problem persists,
perform
DI Test 01
.
16
Local Manual S/D
Local STOP Key on BMS 2000
was pressed to S/D unit from
Normal Operation.
If STOP key was NOT hit and Local Manual S/D cannot be cleared from
annunciation screen, call Combustex. Problem could be a faulty keypad
or main front board circuitry.
17
Low Bath Level
Level sensor indicating Low
Bath Level.
(BMS TS2 #1-2)
Check wiring of Low Bath sensor to BMS. If wiring is OK, check Low level
sensor contact. Replace Low level sensor if contact is faulty. If problem
persists, perform
DI Test 01
.
18
Low Fuel Press. 1
Gas supply signal for Main
Burner 1 indicating low input
fuel pressure.
(BMS TS2 #7-8)
Check wiring of Low Fuel Pressure Switch. If wiring is OK, check Low Fuel
Pressure sensor. Replace sensor if faulty. If problem persists, perform
DI
Test 01
.
