4.
Tap the
RESET
switch until the desired channel is displayed.
5.
The displayed parent channel will have its Red, Yellow, and Green LEDs flashing. A solid Red LED
indicates the conflicting channel (normally the opposing through channel). A solid Yellow or Green
LED indicates where the Flashing Yellow Arrow should be connected. See Section
information.
6.
Press and hold the front panel
RESET
switch until 1 beep is heard to return to normal operation.
NOTE: The monitor will continue to operate normally while in the diagnostic display mode. Any fault detected
while in this mode will be displayed correctly when returned to normal operation.

SWITCH 3 - +24VDC ENHANCED MONITORING (24V ENH)
When ON, the monitor will also check the +24VDC input for over voltage (greater than 30V
DC
) and excessive
ripple (greater than 1V
RMS
). When OFF, the st24VDC monitoring is selected.
When the En24VDC Monitoring is enabled, the
VDC FAILED
indicator will flash at a 5 Hz rate when
the +24VDC input is above 30V
DC
. The indicator will flash at a 1 Hz rate when the ripple on the +24VDC input
exceeds 1V
RMS
. See Section
for more information.
4.1.3.4
SWITCH 4 – SPECIAL FUNCTION 1 INVERT (SF1 INV)
When ON, the monitor will sense the Special Function 1 input as active in the LOW state (less than 50V
RMS
). The
Special Function 1 input must remain in a state for at least 550 milliseconds to be recognized as in that state. See
Section
for more information.
4.1.3.5
SWITCH 5 – SPECIAL FUNCTION 2 INVERT (SF2 INV)
When ON, the monitor will sense the Special Function 2 input as active in the LOW state (less than 50V
RMS
). The
Special Function 2 input must remain in a state for at least 550 milliseconds to be recognized as in that state. The
Special Func 2 Enable
user option in RaeComM must be selected in order for Special Function 2 to function. See
Section
for more information.
4.1.3.6
SWITCH 6 – GY-DUAL INDICATION MONITORING (GY MON)
When ON, the monitor will check for simultaneously active Green and Yellow field signal inputs on the same
channel. This feature will be active on all channels that do not have a Yellow Disable jumper installed on the
Program Card and is not active if the RED ENABLE input is not active.
The GY Dual Indication Monitoring enable can be used in conjunction with the DUAL ENABLE switches on the
circuit board. Channels that have their DUAL ENABLE switches ON will perform Dual Indication monitoring as
described in Dual Indication Monitoring (Section
). Channels that have their DUAL ENABLE switches OFF
will perform the GY Dual Indication Monitoring (Section
4.1.3.7
SWITCH 7 – 2010 MODE – 2010
When ON, the monitor will operate in the 2010 mode of operation. When OFF, the 210 mode of operation is
selected. For a detailed description of the differences in these two modes see Section
4.1.3.8
SWITCH 8 – LED THRESHOLDS (LED THR)
The monitor can use the standard incandescent field display thresholds or enhanced LED field display thresholds.
The active threshold is selected with Option switch 9. When Option switch 9 is OFF the standard incandescent
field display thresholds are selected. When Option switch 9 is ON the enhanced LED field display thresholds are
selected. For a detailed description of the difference in these two thresholds see Section
4.1.4
OPTION JUMPERS
There are four sets of jumper-hole pairs on the PC board that are used to
enable one or more of four user selectable options. The jumper-hole
pairs, labeled J2, are located in the upper center portion of the circuit
board. The numbers 1 through 4 correspond to the option that the jumper
enables. When a jumper is installed in one of the jumper-hole pairs, then
the option corresponding to that jumper hole pair is enabled.
4.1.4.1
JUMPER 1 – DO NOT ALLOW 16 CHANNEL
PROGRAM CARD (NO CH16)
When this jumper is installed, the monitor will not accept 16 channel Program Cards. When jumpered and a 16
channel Program Card is inserted, then the monitor will display a
PC AJAR
fault with all three field indications
for channels 1 through 16 flashing. See Section
for more information.
4.1.4.2
JUMPER 2 – DO NOT ALLOW 18 CHANNEL PROGRAMM CARD (NO CH18)
When this jumper is installed, the monitor will not accept 18 channel Program Cards. When jumpered and an 18
channel Program Card is inserted, then the monitor will display a
PC AJAR
fault with all three field indications
for channels 1 through 18 flashing. Also, when this feature is enabled, the channel 17 and 18 Red, Yellow, and
Green field indications will not show the function disabled blip when a 16 channel Program Card is installed. See
Section
for more information.
