The service screen (Figure A.21) allows access
to the unit "jog" feature, diagnostic screen and
version screen:
•
Rotation – Allows the unit to run for a short
period to check rotation. When pressed, the
unit will either begin the "jog" sequence or
show a screen instructing you to place the
unit in "OFF" mode first (the unit must be
in "OFF" mode before it can check rotation).
When "jog" mode is started, the unit will first
delay for 5 seconds to allow the user to get in
position to check the rotation, then run the
unit for a brief period.
•
Diagnostic – Depicts the I/O status of
the connecting unit controller board. For
example, the digital inputs (X1-X4 as 0 or 1),
the analog readings (T1-T3 and I1 with A/D
values), the 24VDC powered digital outputs
(Z1-Z5 as 0 or 1) and the dry contacts (Y1-Y3
as 0 or 1).
•
Version – Displays the RS-485 communication
version, the firmware versions for the 3.5"
display board and the connecting controller
board.
•
Testing – Allows for test mode of all shutdown
events. See Section A.5 for more information.
