If you turn the signal generator off, and then back on, what do the sequence of the 1 2 3 4 lights do? The proper sequence is for them to turn on and off in sequence from 1 to 4. If the lights instead turn all on and stay on, or all on and then immediately off, then the firmware in the signal generator would need to be re-flashed.
Depending on what version of Torchmate 3 you are running, we may be able to update it to the latest version (3.0.19) and see if the firmware update will reset the signal generator. If it doesn't, the unit will need to be sent back to reprogram the firmware.
