Symptom #7:
Absolutely No Functionality (How to determine which component is at fault)
Step:
Component to Test
Instructions
1.
Verify Power Supply
With a Multimeter, measure the DC
Voltage of the supply while it is
connected to the Connecting Block. Put
the Negative lead of the meter on the
terminal marked GND and the Positive
Lead on the terminal marked 12VDC (or
V). You should get a reading between
11.5VDC and 13.0VDC. If not, remove
the supply from the Connecting block
and measure again this time directly on
the 2.5mm Coaxial plug. If it reads
between 11.5VDC and 13VDC, power
supply is most likely good. Reconnect to
the Connecting Block and proceed to
step 2.
NOTE: In most cases this will
indicate the supply is good but in
some cases the supply can still be
bad (i.e. reads good when not
plugged in but may not be able to
handle the current load of the
system.)
2.
Verify Emitter. (283M or 286M
Blink
Style ONLY)
Remove the power supply from the
connecting block and all Emitters from
the output. Place a jumper wire on the
connecting block between IR and +12v.
Reconnect the Power Supply and
one
emitter. The Emitter should Light bright
and solid. Repeat for all emitters.
3.
Verify Emitter. (282M or 284M
NON
Blink
Style)
Use a diode tester to verify proper
Emitter operation. Remove Emitter from
Connecting Block. Place the Positive
Lead of the tester on the TIP of the
Mono Mini Plug and the Negative Lead
on the Shield of the Mono Mini Plug.
Meter should read a voltage. When the
leads are reversed (Positive lead on
Shield and Negative lead on TIP) you
should not get any voltage reading at all.
