Latching/Non-sequential Mode
In this mode of operation, the displays are the same as the Latching/Sequential Mode, and the
unit operates in almost the same manner. The main difference is that either input
mic 1
or
mic 2
can initiate the reaction timing sequence of closing Relay 3 contacts and starting the clock
display.
Mic 1
trigger still latches Relay 1 and a
Mic 2
trigger still latches Relay 2.
Relay 3 closes when the first microphone trigger occurs and opens upon the reception of the
second trigger on the other microphone.
Non-latching/Sequential Mode
When the Non-latching/Sequential Mode is selected the display will read the following;
TESTING
VOL DLY QUIT
At this point, testing can immediately begin. Since this is a sequential mode of operation,
microphone 1 must produce a trigger input before microphone 2's input will become valid.
If microphone 1 has produced a trigger, and microphone 2 has not produced a trigger, the unit
will ignore microphone 1's inputs until microphone 2 has produced a trigger input.
Once triggered, the corresponding relay will close for the amount of time determined delay.
The microphone sensitivity levels can be changed at any time by pressing the
VOL
button and
following the procedure that was outlined in
Latching/Sequential Mode,
instruction # 2 (pg. 4).
If the delay is to be adjusted, the user is to push the button underneath
DLY
on the display.
The next screen will display the following;
SELECT RELAY
RLY1 RLY2 OK
Pressing the
OK
button will bring you back to the testing mode. Pressing
RLY1
button will allow
the user to adjust the "relay close" period for Relay 1. Pressing the
RLY2
button is for adjusting
this time for Relay 2.
