Timer Setup - Checking Electric Eye Alignment
To work properly, the infrared light source (Transmitter) and
infrared light detector (Receiver) must be properly aligned.
The procedure for aligning the electric eyes is discussed in
detail in the "Aligning the Electric Eyes" section.
Checking alignment of the electric eyes is a setup option
provided by the MD-300 Timer. To check alignment of the
electric eyes, press the
SETUP
button. The first item dis-
played is the alignment status of the electric eyes connected
to the
RECEIVER
jack. If the eyes are properly aligned, "Good"
is displayed. If not properly aligned, "Bad" is displayed. An
alignment status of "Good" not only indicates that the elec-
tric eyes are aligned, but also verifies that all connections
between the electric eyes and the Timer Console are good.
Once the alignment of the electric eyes has been checked,
press the
EXIT SETUP
button to return to normal timing op-
eration.
Note that if you break the beam while checking the align-
ment status, the display shows "Bad" while the beam is bro-
ken. After the beam is restored, the display returns to
"Good."
If the currently selected event type uses more than one
electric eye, the alignment status of each additional electric
eye can be displayed by using the
NEXT
and
PREV
keys to
move forward and backward through the list of electric eyes
(see the "MD-300 Setup Options Table"). More information
regarding alignment of additional electric eyes is provided in
the user's manuals which come with the OE-205 Electric
Eye Package and the RP-250 Electric Eye Barrier.
Timer Setup - Selecting Event Type
One of the most important features of the MD-300 Timer is
its ability to support a wide variety of events. The event
types present in the MD-300 Timer are listed in the "MD-
300 Setup Options" table and summarized in the "Event
Summary" table. Even though a particular event may not be
listed in these tables, it is most likely supported by one of
the event types that is present. For example, though pole
bending is not specifically listed as an MD-300 event type,
pole bending has the same basic timing requirements as
barrel racing. Likewise, bull dogging and goat tying have
similar timing requirements as roping events.
When the MD-300 Timer is first turned on, the "Barrel"
event type is automatically selected. (Note: You can change
the event type selected at power-on to be any of the other
event types as well. Contact FarmTek for assistance.) If you
requested factory setup of a power-on event type other than
"Barrel," it is shown here:
To change the current event type, press the
SETUP
key to en-
ter the setup mode. As shown in the "MD-300 Setup Options
Table," ten of the setup options available are event types
that may be selected. Use the
NEXT
and
PREV
keys to scroll
forward and backward through the list of events until the
desired event type is displayed. Then press the
SELECT OP-
TION
button to select the displayed event type. "Done" is dis-
played for a moment to indicate that your request has been
performed. The timer then returns to the timing mode with
the time reset to zero.
Note that the new event type is selected only when
SELECT
OPTION
is pressed. You may exit setup without changing the
event type by pressing
EXIT SETUP
. Also note that whenever
the currently active event type is displayed, the timer beeps.
This allows you to determine the event type currently in use.
Whenever a new event type is selected, the MD-300 Timer
automatically sets the time format, counting direction,
warning horn time and final horn time for that event. These
values can be different for each event type. Further, you
may change these defaults to any value you desire. When-
ever the event type you modified is selected, your values for
time format, counting directions, etc., are automatically set.
See the "Timer Setup - Setting Default Parameters" section
for more information.
The following "Event Summary" table provides information
about each event supported by the MD-300. If optional
equipment is required to support an event, additional in-
formation is provided in the manual supplied with the op-
tional equipment.
