When
the
ALARM
Sounds
A new feature, that was requested, has been added to the unit concerning when the alarm lights and buzzer
sounds. There is NO ‘Silence the Alarm’
1.
If the Alarm LED is light solid and the buzzer sounds without pauses, you have an Over-Current
condition.
a.
-Solution: clear the over-current condition.
2.
If the Alarm LED is light intermittent and the buzzer sound intermittent on a cyclic rate of long beep,
long pause than beeps again, one of the input voltages has either a “Loss of Power”, a Brown-Out”
condition, or the unit is operating on the secondary input.
a.
-“Loss of Power”, restore the power to proper voltage level. The unit will switch to the primary
after 8-seconds plus any time delay set in the switch-back feature of the ‘Config/Option (7),
Change ATS Switch Back Mode/Time’,
Default
is (0) seconds.
b.
-“Brown-Out”, verify the input voltage is at the proper voltage level.
c.
-“Unit operating on Secondary Input Voltage”, If ‘Config/Option (7) Change ATS Switch Back
Mode/Time’ is Disabled the unit will not switch back to the Primary; the alarm will light and the
buzzer will sound continuously. If the Switch Back Mode is enabled, the unit will switch (8)
seconds plus any time delay set. The
Default
time delay is set to (0) seconds.
SCROLLING MENU:
This may occur in a Master/Slave setup, due to the Master unit being power-up after
the Slave unit and the 8” data cable connecting the serial ports of the Master and Slave together.
CORRECTIVE ACTION:
Type “Ctrl+C” then press ’Enter’ to refresh the menu. The keyboard
“Alt+Break” may also work in some programs. The terminal program may have a break command that may
also stop the scrolling. The three break commands work in MS-Hyper-Terminal, Putty, and Reflections.
SMILEY FACE and HEART
Symbols (
☻♥
): Connecting to the EAI232 serial port, the cursor is jumping
back and forth from the Face to the space to the right of the Heart. If these two symbols are displayed, the
Master unit has the Cascade feature enabled and the Ethernet cable is connected. Some terminal programs
will have the cursor do a line-feed and the program appears not to respond.
CORRECTIVE ACTION
: Disconnect the Ethernet cable and wait about 10 seconds for the serial port to
revert back to the normal operations with the menu.
