FRONT PANEL DESCRIPTION
5.1 INDICATORS
5.1.1 (G) AC POWER INDICATOR
The AC POWER indicator will illuminate when the AC Line voltage level is above the brown-
out "restore" level. The indicator will flash at a rate of 2Hz when the AC Line voltage is below
the "drop-out" level. The indicator will extinguish when the AC Line voltage is less than 75 +
_
2 Vac. During the minimum flash interval the indicator will flash at a rate of 4Hz. See Section
2.5.
If the 210E / 2010 model is in the Diagnostic Display mode, the (G) AC POWER indicator will
flash ON once per second to indicate the Channel Status display is showing Green channel
status. See Section 2.18.
5.1.2 (Y) VDC FAILED INDICATOR
The VDC FAILED indicator will illuminate when a 24VDC fault condition is detected. This
indicator remains extinguished if the monitor has not been triggered by a 24VDC fault.
If the 210E / 2010 model is in the Diagnostic Display mode, the (Y) VDC FAILED indicator
will flash ON once per second to indicate the Channel Status display is showing Yellow
channel status. See Section 2.18.
5.1.3 (R) WDT ERROR INDICATOR
The WDT ERROR indicator will illuminate when a controller Watchdog fault is detected. If
the WD ENABLE switch is placed in the OFF position to disable Watchdog monitoring, or the
AC Line voltage is below the Watchdog disable level, the WDT ERROR indicator will flash
ON once every 2 seconds.
If the 210E / 2010 model is in the Diagnostic Display mode, the (R) WDT ERROR indicator
will flash ON once per second to indicate the Channel Status display is showing Red channel
status. See Section 2.18.
5.1.4 CONFLICT INDICATOR
The CONFLICT indicator will illuminate when a conflicting proceed signal fault is detected.
The CONFLICT indicator will illuminate when a FYA Flashrate Fault (see Section 2.20.1.1.2,
2.20.2.1.2) has been detected. In this fault mode the channel status indicator will flash to
indicate the affected channel(s).
5.1.5 RED FAIL INDICATOR
The RED FAIL indicator will illuminate when an absence of signal is detected on a channel(s).
If the Red Enable input is not active or the EE input (MC Coil) is active the RED FAIL indicator
will flash once every two seconds to indicate that Red Fail Monitoring functions are disabled.
5.1.6 DUAL IND INDICATOR
The DUAL IND indicator will illuminate when a GY-Dual or GYR-Dual Indication fault is
detected on a channel(s).
5.1.7 CLEARANCE INDICATOR
The CLEARANCE indicator will illuminate when the minimum Yellow Clearance time has not
been met on a channel(s).
