Test program
Running the test program
In order to trace a hardware error easier, each Nord synthesizer has a test program.
This program is primarily used in production in order to test all functions.
The functions provided by the test program allow a quick and easy search for possible
errors on the hardware. On the Nord Modular G2 the five displays guide the user
through the test program. To run the test program on a Nord Modular G2 Engine you
have to connect an external panel board to the G2 Engine.
For more information, see section ”testing the G2 Engine” in this document

WARNING:
Improper use of the test program or powering off the synth during a test
can result in malfunction of the synth. The test program may only be used by qualified
service personnel and is not intended for end users.
In order to execute the different tests on a Nord Modular G2, press and hold buttons
[ Performance Mode + Display Mode + Store ]
at power up.
When test mode is entered, a DRAM test is performed. After the DRAM test has finished
successfully, the test program will start. The DRAM test progress is indicated by the
LED´s on the leftmost encoder on the front panel (indicated by MIDI and USB LED´s on
the Engine). The LED´s are divided into three groups, where each group of LED´s
represents a part of the DRAM test procedure. During the DRAM test, the LED groups
will light up, one by one. If errors are detected, one of the three groups will flash:
- If the first LED group is flashing, error has been detected on
U13
.
- If the second LED group is flashing, error has been detected on
U12
.
- If the third LED group is flashing an address bus error has been detected.
