Step 10 Adjust Voltage at Power Source
To allow for maximum distance between the NGC and the power source,
adjust the no-load output at the power source to 14.5 to 15 VDC for 12
Volt systems and approximately 25 VDC for 24 Volt systems. This
assumes one of the below wire sizes is used, and the optional auxiliary
heater is not used. The maximum wire size is 12 AWG (2.5MM
2
).
Temporarily disconnect power prior to beginning the next step.

NOTE:
It is strongly recommended that 12 or 14 AWG wire be used to
avoid power problems.
Step 11
Apply DC Power to the Termination Board J1 Terminal,
and Check Voltage
Remove the J1 terminal from the NGC termination board, and field wire
power (+) to pin 1 and power (-) to pin 2. Reinstall the J1 terminal on the
termination board. Apply power to the unit. The oven will begin heating
and will provide maximum load conditions. Due to the fast pulsing action
of the oven circuit, the true voltage cannot be read with a traditional
voltmeter. However, using a voltmeter, the user needs to verify that they
can read a minimum of 11.5 VDC at J1 on the NGC termination board for
12 Volt systems or a minimum of 25 VDC at J1 for 24 Volt systems.
Voltages must
NEVER
drop below 10.5 VDC on the 12 Volt system or 21
VDC on the 24 Volt system.
Maximum instantaneous current for a 12 Volt system should be between
4 Amps (no auxiliary heater) and 8.2 Amps (with auxiliary heater).
Maximum instantaneous current for a 24 Volt system should be between
2.2 Amps (no auxiliary heater) and 5.2 Amps (with auxiliary heater).
Maximum instantaneous current is usually experienced at start-up.
Start-Up
Step 12 Install the PCCU32 Software Provided on CD
12A
Insert the PCCU32 disk into the laptop’s CD drive. The
installation process should begin automatically. If not, click the
Start button, and select Run. In the Run dialog box, type:
D:\Disk1\setup.exe
(D being the CD drive designation).Follow
the screen prompts. The user needs to enter their name,
company, destination folder (PCCU_NGC recommended) and
program folder.
