LED colour
Meaning
DSi is in initialisation mode. Rotate the axis in one direction until the LED
Green (fl ashing)
turns solid green to exit initialisation mode. NOTE: during high-speed
rotation, the blank fl ash of the LED as the axis passes the propoZ position
may appear like a fl ashing green LED.
If the LED continues fl ashing green check for correct position of the
orientation switch and press and hold the propoZ button on switch-on.
Green (solid)
DSi is in normal working mode.
Blank
Axis is at the propoZ reference (index) output position.
NOTE: if you drive the axis past the propoZ position, the blank LED will
appear as a 0.25 second fl ash.
Orange
A new propoZ position is being programmed. When the propoZ button is
(propoZ button is
released, the LED will normally show blank unless the axis is moved from
being pressed)
the propoZ position.
Red (solid)
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 fi rst installed. This could be caused by a
miscount from one of the TONiC 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. Re-calibrate the DSi as per
the initial installation.
NOTE: on re-calibration, the old propoZ position will be lost.
Red (fl ashing)
An alarm has occurred on one or both of the TONiC interfaces.
Red, then orange,
The DSi has returned to factory default settings. This is triggered by
pressing and holding the propoZ button while the DSi is being
then fl ashing green
powered up.
