Led Identification - Janome QMP16SU Manual

LED Identification

When you first power on the Janome QMP16SU,
each of the LEDs on the control board LED bank
will briefly flash in succession. Following that
initial flash, the LED (labeled HrtBt) should flash
in a "heart beat" fashion to indicate that the
processor is running and is not locked up. If the
processor is locked up, these LEDs will be locked
in either an On or an Off state.
A description of each of the 8 LEDs and its
function is listed below.
• D3 HrtBt: Flashing in a "heartbeat" fashion
indicates the processor is running.
• D6 Speed: Flashes 100 times per revolution of the hand wheel.
• D5 Option: Should be on when the stitch regulation over speed alarm is on.
• D4 Needle: Should be Off when the take-up lever is all the way in the Up position. Should be On when
the take-up lever is down or anytime it is not fully in the Up position.
• D10 Test 4: Should flash rapidly when communication with the front handlebars is established.
• D9 Test 3: Transmit LED should flash rapidly when communication with the handlebars is established.
• D8 Test 2: Should be On when stitch regulation is on.
• D7 Test 1: Turns on when the Start button is pressed, indicating that the motor should be running (Go
LED.)
