3. Locate or obtain a replacement power supply module (Nautel Part # UG69). Reverse Step 1
through Step 2 to reinstall the new power supply module. The transmitter should resume
normal operation and the alarm should clear.
4. If you have purchased the power supply extension assembly (Nautel Part # 206-5750), you
can use it to bench test and troubleshoot power supplies before returning them to service.
Refer to
“Using the power supply extension assembly” on page 1-44 for more information.
Using the power supply extension assembly
The power supply extension assembly (Nautel Part # 206-5750) is an option available from Nautel
that allows convenient bench troubleshooting access to a power supply while it is connected to the
transmitter.
The assembly consists of three parts, which are pre-connected for customer convenience:
– A1: 206-5700 Power Supply Extension Module
– A2: 206-5708 Power Supply Support
– 206-5702 Cableform Assembly (interconnects A1 and A2)
1. Remove or verify a power supply has been removed to allow insertion of the power supply
extension assembly.
2. Obtain the power supply extension assembly (Nautel Part # 206-5750).
3. Carefully push the power supply extension module end (A1) of the assembly into the vacant
power supply position so that its card-edge connector mates with the transmitter. No
securing hardware is required.
4. Place the power supply support end (A2) of the assembly on a suitable test surface that is less
than 15 feet (4.5 m) from the transmitter. The power supply support contains holes to allow
mounting to the test surface, but it is not necessary.
WARNING:
Lethal voltages exist inside the power supply module when power is
applied or had recently been applied (within 10 minutes). Opening the
power supply module to troubleshoot will void your warranty.
Contact Nautel before attempting to troubleshoot a power supply
module.
