Diagnostics Indicator:
This bright, segmented LED display on the control module front
panel indicates one of 10 System status conditions, plus the presence or absence of
blanking. (Blanking ON causes a period to appear in the Diagnostics Indicator window,
in addition to the System’s other status condition.) See Figure 6-2 for the key to these
error types and status conditions; this chart is also located on the side of the control
module.
Emitter:
OPERATIONAL:
(red) LED indicates power to the emitter is ON, and unit is operational.
Receiver:
BLOCKED:
(red) LED indicates some of the array beams are blocked.
MARGINAL:
(yellow) LED indicates that array alignment is marginal.
ALIGNMENT:
(green) LED indicates that array alignment is satisfactory.
To improve alignment, adjust the position of the emitter and receiver until the green LED
lights, making sure that no unblanked beams are interrupted. Then use one of the methods
in Section 5.2 to realign the system.
6.2 Diagnostics Routine
Emitter or receiver problems may be further diagnosed using the
Diagnostics routine included with the MINI-ARRAY software.
Launch the program by selecting
Diagnostics
under the MINI-
ARRAY menu (Figure 5-2) or by pressing
F2
.
The Diagnostics screen (Figure 6-3) displays the size of each
emitter and receiver (expressed in the number of 64-element
“boards” it contains) and its functional status (or state). If an
error has occurred, the specific problem beam channel is
identified. Additionally, if there is a problem with an emitter or
receiver cable connection, a “
No Response
” message is displayed.
The Diagnostics routine also displays the part number and date
code of the controller, information that may be useful if factory-
assisted troubleshooting by telephone is required.
