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...
