Besa Lighting 8 Ft Monorail (Monorail 12V) - Manual (Page 4)

Power

Either MR16 or
Standard BiPin
12V lamp.
IMPORTANT:
Lamp will NOT light when
contacting bottom or outside
of the adapter halves. Only
the inner edges of the adapter
halves will light the lamp.
IMPORTANT:
Must use a 50W Lamp
to test the R12-SA150
(150W Electronic)
Power Supply.

3. Confirm that the Power Supply is operating properly. For a magnetic
Power Supply, simply use a multi-meter to confirm 12V output.
For an electronic Power Supply, see below.
NOTE: Verify that the Power Supply Circuit Breaker is reset before testing operation.
i. Our electronic Power Supply output (R12-SA150) is high frequency
and cannot be seen by most multi-meters. A simple lamp test can
verify the status of the Power Supply.
CAUTION: Have a qualified person perform this operation. Do NOT
hold Lamp with bare hand as Lamp heats quickly and may cause injury.
Hold the Lamp carefully using pliers or insulated gloves.
ii. Remove Rail from Power Adapter coming from the Power Supply,
then restore power to the Power Supply.
iii. Hold a 12volt lamp and raise it to the Power Supply. Touch the
pins of the lamp to the inner edges of each half of the Adapter.
Do this only for 1 to 2 seconds! A lit lamp indicates a good Power Supply.
Contact your local Besa Distributor or Besa Customer Service
if a replacement Power Supply is needed.
iv. Turn off power and reinstall Monorail to the Power Adapter.
B) Problem: Sections of the system (not the fixtures)
feel hot to the touch.
1. Heat is an indication of a poor electrical connection. The high
current in low voltage systems requires intimate contact
between conducting parts. If only a partial connection is
present the system may still operate but the current flow
through the small contact area will heat up.
CORRECTIVE ACTION: Make sure connections involve firm
metal to metal contact, firmly tighten the screws on rail adapters,
quick connects and fixture adapters. Operate system for 20 to 30
minutes and re-check the hot spot. If not corrected replacement
of the part is warranted.
C) Problem: Lights burn out quickly,
or burn very brightly.
1. Bad socket connection.
CORRECTIVE ACTION: Inspect Lamp Pins and Socket Contacts
for evidence of discoloration. Pendant Lead replacement is
necessary if the Socket Contacts are discolored.
2. Finger oils on quartz lamps.
CORRECTIVE ACTION: Wipe the glass with a clean soft cloth
on all lamps after installation.
D) Problem: System comes on but lights flicker
or are dim.
1. Insufficient minimum load…… (Electronic transformers only)
CORRECTIVE ACTION: Increase lamp load to above
the minimum (see transformer instruction sheet).
2. Wrong lamps installed; 24 volt lamps operating from
a 12 volt power supply.
CORRECTIVE ACTION: Re-lamp with 12 volt lamps.
3. If lamps become dim or flicker after operating normally
over for a period of time. This is a sign of deteriorating
12volt connections due to the high current.
CORRECTIVE ACTION: Re check all secondary connections,
paying close attention to any discoloration, oxidation or
hot spots and tightening loose connections. Pendant Lead
replacement is necessary if the Socket Contacts are discolored.
E) Problem: The circuit breaker on the main panel
trips on initial power up.
1. There may be a short on the 120-volt side of the transformer.
CORRECTIVE ACTION: Check all connections and repair
if needed, then confirm operation.
1. Verify that 1/8” of insulation has
been trimmed from the inner wire.
2. Verify that approx. 1/16” of braided
wire protrudes from the top of the collar.
3. The distance from the bottom of the collar
to the top of the inner wire should be 1 3/4”.
4. Reinstall the Quick Connect part, verifying that the 1/8” of
bare conductor has been extended into the top part. The top
set screw must make contact with the bare conductor.
5. Perform continuity check before mounting. If an open or
short still exists, then a complete Quick Connect reinstall
is recommended. Cut the cord below the collar and follow
the instructions provided with the pendant.
Quick Connect Repair
Remove the Quick Connect Jack from the cord and follow the troubleshooting directions below:
