B10 PROBLEMS WITHOUT ERROR CODES
In addition to the Error Codes listed above, some problems may not
necessarily generate Error Codes. The following give some exam-
ples where the Processor may not detect a fault, though the opera-
tion may not be perfect:
B10-1B
ASIC
C
ONTROL
S
YSTEM
P
ROBLEMS
W
ITHOUT
E
RROR
C
ODES
A)
SYMPTOM:
No audible tones heard at one Control Station
when power is first applied to the Processor. All other features
function normally.
B)
SYMPTOM:
The Control Head’s red LED doesn’t light when in
command, but otherwise functions properly.
C)
SYMPTOM:
When power is turned ON to the Processor, there
are no tones from any of the Remote Stations, the Control Head
red LED does not light when the Transfer Button is pressed,
and the Display is not lit at the Processor
.
D)
SYMPTOM:
The engine begins to turn-over while starting and
then stops. A slow repetitive tone is heard from all Remote Sta-
tions.
Cause Remedy
a. Incorrectly wired Station Harness/ Cable
or Pigtail.
a. Verify that the black wire is properly con-
nected to pin 1 on the Control Head and Pin
8 at the Processor.
b. The Control Head’s Sound Transducer is
defective.
b. Measure the AC voltage at pins 1 & 3 of the
Control Head. If 20- 25 VAC is present,
replace the Control Head.
Cause Remedy
a. Incorrectly wired Station Harness/ Cable
or Pigtail.
a. Verify that the brown wire is properly con-
nected to pin 2 on the Control head and pin 2
at the Processor.
b. The Control Head’s red LED or circuit is
open.
b. Measure the DC voltage at pins 2 & 3 at the
Control. The measurement will be approxi-
mately 2.20 VDC when the red LED is lit. If
4.00 VDC is measured, the red LED or its cir-
cuit is open. Replace the Control Head.
Cause Remedy
a. No power to the Processor. a. Disconnect the Power Harness from the Pro-
cessor. Measure the DC voltage at pins 10 (+)
and 11 (-) of the Harness plug. If 12 or 24
VDC is not present, check the circuit break-
ers, switches and cables feeding power to the
Processor. Correct the power source as
required.
b. The battery’s polarity is reversed at the
Processor.
b. Disconnect the Power Harness from the Pro-
cessor. Connect a voltmeter’s red lead to pin
10 and the black lead to pin 11 of the Har-
ness’s plug. If negative voltage is measured,
reverse the wires.
c. Defective Processor. c. If Causes a. and b. were not the fault, replace
the Processor.
Cause Remedy
a. The voltage available at the Processor
has dropped too low, due to the starter’s
current requirement
a. Supply power to the Processor from a battery
other that the starting battery or supply
power from two sources through an APS
(Automatic Power Selector)
b. Battery charge is too low b. Recharge/ replace the battery or supply bat-
tery power from two sources through an
APS.
