Master Control Panel Description
Observed Frequency
- This alarm occurs when the built in frequency counter detects the
measured frequency is out of tolerance with the desired frequency.
Incorrect Identification
- This alarm occurs when the monitoring circuitry detects a different
Identifier from the desired Identifier. The LED's above the monitor enable switch indicate the
present status of the transmitters. The PRI LED indicates the primary transmitter selected by the
main TX select key is the operating transmitter. The SEC LED indicates failure in the Primary
t
r
ansmitter and the monitoring circuitry has commanded the transmitter to switch to the
secondary transmitter. The fail LED indicates that both transmitters have failed and the system
has shut down.
When testing the SE transmitter, Monitor Enable must be turned OFF.
4.1 Special Functions on the (SPCL FCTN) Key
All Functions are SPCL FCTN Key + Number
SPCL FCTN +1
This mode stores all data into the onboard EEPROM. Once data is stored, the transmitter will
come back to the original settings if AC and DC power are lost.
SPCL FCTN + 2 (Software not available at this time)
This sets the code speed. Display will show default code speed of 8 wpm. Use the UP/DWN
keys to the right of the LCD to slow down or speed up the code speed, with a limit of 5 wpm to 15
wpm.
SPCL FCTN +3 (Software not available at this time)
Master Reset of the Transmitter Controller. This function allows the Master Controller to reset
the transmitters.
SPCL FCTN +4 (Software not available at this time)
Clears Master Reset. This function clears the Master Reset function of the Transmitter Controls
created by SPCL FCTN+3.
SPCL FCTN +5 (Software not available at this time)
This is a special test mode. In this mode the Master Controller will test for under modulation
shutdown. The Master Controller commands the Transmitter Control to decrease the modulation
level by 5 percent intervals in 5 second intervals. As the transmitter changes modulation level, it
is still sending back data on all of the parameters associated with that transmitter. Once the
modulation level drops below an acceptable level, the Master Controller will institute a transmitter
changeover and shutdown of the offending transmitter.
SPCL FCTN +6
This is a special test mode. In this mode the Master Controller will test for improper identification.
The Master Controller commands the Transmitter Control to reverse the identification. After the
transmitter changes identification, it is still sending back data on all of the parameters associated
with that transmitter including identification. Once the identification changes, the Master
Controller will institute a transmitter changeover and shutdown of the offending transmitter.
