FUNCTION DISABLED INDICATION
When a function has been disabled, the associated indicator will turn on for 50 milliseconds once every two
seconds.
Functions may be disabled for one of several different reasons:
INDICATOR
DISABLE CONDITIONS
WDT ERROR
The circuit board switch labeled WATCHDOG is in the DISABLE position.
CH 17 & CH 18
A 16-channel Program Card is inserted in the monitor.
RED FAIL
The Red Enable input (Red Interface Connector - Pin a) is below 70V
RMS
.
The MC Coil input (Rear Edge Connector - Pin EE) is below 70V
RMS
.
Special Function 1 input (Red Interface Connector - Pin 8) is active.
Special Function 2 input (Red Interface Connector - Pin 6) is active.
MULT IND
The Red Enable input (Red Interface Connector - Pin a) is below 70V
RMS
.
YELLOW
The Red Enable input (Red Interface Connector - Pin a) is below 70V
RMS
.

AUDIBLE BUZZER
The monitor is equipped with an audible buzzer. This buzzer is used to bring important events to the attention of
the user. The buzzer can be disabled for pending configuration notifications only. This can only be done through
the RaeComM software under CONFIG > MONITOR CONFIGURATION > ELECTRONIC OPTIONS.
4.3.1
CRITICAL FAILURE
When the monitor main microprocessor is held in the reset state due to a critical hardware failure, the buzzer will
stay on constantly. There is no way to disable this indication, as it is an indication that the monitor is not
operational.
4.3.2
CONFIGURATION CHANGE
The monitor checks for configuration changes every second. A configuration change is defined as a change of any
of the following parameters:
Programming Card diodes and jumpers
Program Card Type (16 or 18 Channel)
Printed circuit board switches and jumpers
Factory Setup Options set through the RaeComM software
Software Options set through the RaeComM software
If a configuration change is identified, the monitor will enter a configuration fault mode and the audible buzzer will
start to beep at a one second rate. This is an indication that a change to the current configuration has been
identified. The monitor does not implement any configuration changes until the front panel
RESET
switch is
activated and held for five seconds. At that time the buzzer will chirp five times then stop beeping. If the
configuration parameters that were changed are restored to their original states, the buzzer will stop beeping but the
RESET
switch will have to be pressed to return from the fault state.
NOTE: If power is removed from the monitor prior to the configuration changes being accepted by pressing the
RESET switch, the pending changes will still be pending and the original settings will be used on power up.
4.4
DIAGNOSTIC DISPLAY MODE
The monitor supports a diagnostic display mode that allows the user to view the current line voltage, active
configurations settings, and past faults. This information is viewed on the field status indicators and the fault
indicators. The display identifier will be displayed for 0.5 seconds followed by the data for 2.5 seconds. This
display sequence will be repeated as long as the diagnostic display mode is active.
To display the Ethernet IP address, press and hold the front panel
RESET
pushbutton for more than 3 seconds but
less than 5 seconds. The buzzer will emit a single chirp when 1.5 seconds have elapsed and two chirps when 3
seconds have elapsed. This is an audible cue to release the
RESET
pushbutton to view the Ethernet IP address.
To exit the diagnostic display mode, repeat the procedure used to enter the mode.
To enter the diagnostic display mode, press and hold the front panel
RESET
pushbutton for more than 1.5 seconds
but less than three seconds. The buzzer will emit a single chirp when 1.5 seconds have elapsed. This is an audible
cue to release the
RESET
pushbutton to enter the diagnostic display mode. To exit the diagnostic display mode,
repeat the procedure used to enter the mode.
