DSi LED diagnostics
LED colour
Green (flashing)
DSi is in initialisation mode. Rotate the axis in one direction until the LED turns solid green to exit initialisation mode.
Green (solid)
DSi is in normal working mode.
Blank
Axis is at the propoZ reference (index) output position.
Orange
A new propoZ position is being programmed. When the propoZ button is released, the LED will normally show blank unless
(propoZ button is being pressed)
the axis is moved from the propoZ position.
Pulse count alarm has been asserted. The number of counts in the last revolution is different to the value stored during the
automatic calibration routine when the DSi was first installed. This could be caused by a miscount from one of the TONiC
Red (solid)
encoders. If the pulse count alarm is asserted repeatedly, it is possible that an incorrect count is stored inside the DSi, in
which case the DSi should be powered-up with the propoZ button pushed in to restore factory defaults. Recalibrate the DSi
as per the initial installation.
Red (flashing)
An alarm has occurred on one or both of the TONiC interfaces.
Red, then orange, then flashing
The DSi has returned to factory default settings. This is triggered by pressing and holding the propoZ button while the DSi is
green
being powered up.
1
During high-speed rotation, the blank flash of the LED as the axis passes the propoZ position may appear like a flashing green LED. If the LED continues flashing green check for correct position of the orientation switch
and press and hold the propoZ button on switch-on.
2
If you drive the axis past the propoZ position, the blank LED will appear as a 0.25 second flash.
3
On recalibration, the old propoZ position will be lost.
