4.5 Operating status LEDs
There are six operating status LEDs on the top cover of the SPM Power Selector
Module. Table 4-3 below provides the key for each LED indicator.

4.6 Power cycling
4.6.1 Power up sequence
The 24V supply to the SPM Power Selector Modules must be applied before the
Unidrive SPM power and control modules are powered up. Failure to do so will cause
the 'POWER SEQ' LED to light on the SPM Power Selector and the Unidrive SPM will
trip.
When the 24V supply is applied to the SPM Power Selector Module, the 'PS ON' LED
will light along with either the 'Master 1' or 'Master 2' LED depending on the state of the
'Master mode select' input.
When the Unidrive SPM power modules are powered up, the 'PM ON' LED will light.
