Shaft Encoder Replacement
There are two possible replacement parts for a broken shaft encoder: a simple shaft
encoder (X50SPR-SE) that must be soldered to the front circuit board, or a complete circuit
board unit (X50SPR-DISP).
To replace a complete circuit board unit because of a broken shaft encoder, see
on page 110. To replace a broken shaft encoder separately,
follow these steps:
1
Disconnect
both
power cords and remove the cover as described on page 106.
