THE MONITOR FUNCTIONS 'POWER OUT' LIGHTS, BUT
FOLLOWING THE TEST SENSOR SIGNALS ARE PARTIALLY
OR TOTALLY MISSING
•
Caused by mistaken switch off of row detection, some rows are missing
from screen. Check again and reset row detection where necessary. (See
SETTING ROW SKIP)
•
Hurt cable or connector, or defected module.
Troubleshooting: push TEST button and note the number of last detected
seed module.
Last
detected
module
E.g. Only 8 sensors are detected of 12. The source of problem can be at the
output side of module 8, or more probably in module 9.
a., LEDs do not light from module 9 up.
- battery leads are probably hurt
- connector is defected between modules 8 and 9.
- output side of module 8 or the module 9 is defected
b., LED lights at modules 9,10,...etc.
- Power supply is in order, communication cables are hurt between
modules 8 and 9 (or connector is defected).
- output side of module 8 or the module 9 is defected.
the easiest way to find defect in a linear system is that you disconnect and bridge
supposed defect module:
•
skipping module 9, connect module 8 directly to module 10
•
skipping module 8, connect module 7 directly to module 9
Push TEST to verify, replace defected module
Important notice: the monitor numbers the seed modules according to
connection order. Consequently, if a module removed, the numbers of
next modules jump one back E.g. if we remove module 9, module 10
becomes module 9, and so on...
