Replacing the DSD Armature Interface PCB
3/21/96
❏ Reconnect the SCR gate leads making sure they are not crossed, and are
pushed all the way in (gate leads will first “click” and can then be pushed in
for an additional 1/8” to 1/64”).
❏ Reconnect the Armature sensor feedback wires making sure to observe the
polarity. If these leads are connected in reverse, a Fault 917 (Reverse
Armature Voltage Connection Fault) will occur.
❏ Reconnect the J24 connector.
❏ Apply power to the drive.
