S
c. Voltage output should be 33VDC +/-
1VDC.
d. If L1 & L2 both have 33VDC power out
the power supply is not the cause of the
problem. Continue troubleshooting the
rest of the light system.
e. If L1& L2 do not have 33VDC power
out, go to step 3.0.
f. If only one light has 33VDC power out
go to step 6.0 to troubleshoot the side
that does not have power out. Inves-
tigate the rest of the light system to
determine why the light that is getting
power from the power supply box is not
working.
Power Supply Box DC Voltage Measurement
3. Is the power supply box plugged in? If yes, go to the next step. If no, plug in the power supply
box and check the light system for normal operation, as per QIP07056.
4. Is the power supply box power switch in the ON position? If yes, go to Step 5. If no, turn the
power switch to the ON position and check the light system for normal operations, as per
QIP07056.
5. Does the AC outlet have line power when measured at the wall outlet?
WARNING To avoid risk of electrical shock, all service must be provided by authorized
personnel.
a. Set multimeter to VAC mode.
b. Insert multimeter leads into the outlet
as shown in the figure below.
c. Voltage output should be 110-120VAC
for 0682-000-055 power supply boxes.
Voltage output should be 220-240VAC
for 0682-000-055i international power
supply boxes.
d. If line power is present and at the cor-
rect voltage, then replace the power sup-
ply box and return it to Stryker Com-
munications through the RMA process.
Line Voltage Measurement
e. If line power is not present, investigate the reason for this. Check the system for proper opera-
tion once line power is restored, as per QIP07056.
6. For a single line that is out, check the power output on the affected light.
a. Power cycle the power supply box by turning the switch on the back of the box off then back
on.
b. Does the affected light turn back on? If yes, then investigate the rest of the light system for a
CAN-BUS problem. If no, then continue to the next step.
