Page 6: Section 1 General
The SSM-LE Series Signal Monitor is a device used in a Traffic Controller Assembly to accomplish the detection of, and response to improper and conflicting signals and improper operating voltages in a Controller Assembly caused by malfunctions of the Controller Unit (CU), load switches, or mis-wiring of the cabinet. -

The loss of AC LINE will not reset the fault mode of the OUTPUT relay contacts. In the event of AC LINE loss the SSM-LE Series will retain the status of all fault and channel indicators and will display the correct fault and channel status upon restoration of AC LINE. -
Page 8: Ledguard Led Field Signal Sensing
LED FIELD SIGNAL SENSING ® The Eberle Design SSM-LE Series can be configured to use a technique called LEDguard that is designed to better monitor the characteristics of LED based signal loads (See Section 5.4.2). Each field signal input is measured and compared to both a high threshold and a low threshold value to determine On / Off status. -

OUTPUT relay contacts to the Fault position, and display the RED FAIL status screen. The SSM-LE Series will remain in the fault mode until the unit is reset by the RESET button or the EXTERNAL RESET input. When voltages on all inputs to a channel are sensed as inactive for less than the Red Fail No-Fault time, the SSM-LE Series will not transfer the OUTPUT relay contacts to the Fault position. -

OUTPUT relay when the True (low) state is restored to the input. The SSM-LE Series will remain in the fault mode for at least the time determined by the Minimum Flash programming. A CVM failure during the programmed Minimum Flash time or during a Power Failure will not cause a fault condition. - Page 11 AC LINE voltage is sufficient for proper operation. The SSM-LE Series should be the first component in the cabinet to sense a low voltage condition and the last component to sense a proper AC LINE operating voltage.

AC Line power. This EEPROM device requires no battery back-up. The time of day in the SSM-LE Series is stored in a battery-backed real time clock circuit. Should this battery fail, only current time of day and date information will be lost. No monitor configuration programming is stored under battery power. -

Pulse detection algorithm will process these pulses into one event and trigger a Conflict fault once the longer recurrent timing threshold is exceeded. When triggered by a recurrent pulse fault condition, the SSM-LE Series will enter the fault mode, transfer the Output relay contacts to the Fault position, and display the appropriate CONFLICT, DUAL INDICATION, or RED FAIL status screen along with RP STATUS. -
Page 16: Basic Fya Mode
Series associates channel 1 with 9, channel 3 with 10, channel 5 with 11, and channel 7 with 12 when FYA monitoring is enabled for that respective approach. If a channel pair is enabled for FYA operation, the SSM-LE Series will monitor the FYA logical channel pair for the following fault conditions:... -

SSM-LE Series Operations Manual A Clearance fault will be detected if the FYAc channel pair sequences from the solid Green Arrow (9, 10, 11, 12) to the solid Red Arrow (1, 3, 5, 7) without a minimum clearance time on the solid Yellow Arrow (1, 3, 5, 7). -
Page 19: Section 4 Eccom Interface
The EDI ECcom software package (Version 3.6.8 or greater is required) interfaces a Computer or System to the SSM-LE Series. The ECcom program will display the Status (S), Previous Fault (PF) event log, AC Line (AC) event log, Manual Reset (MR) event log, Configuration (CF) event log, and Signal Sequence logs. -
Page 20: Configuration (Cf) Event Log
4.1.7 SIGNAL SEQUENCE EVENT LOG The Signal Sequence event log graphically displays all signal states and Red Enable state for up 30 seconds prior to the SSM-LE Series fault trigger for the most recent five (5) Previous Fault (PF) events. -

Series will enter the fault mode, transfer the OUTPUT relay contacts to the Fault position, and display the PROGRAM CARD status screen. The SSM-LE Series will remain in the fault mode until the Program Card is correctly seated and the SSM-LE Series is reset by the RESET button or the EXTERNAL RESET input. -
Page 22: Unit Option Programming
SSM-LE Series Operations Manual The channel SSM switch should be placed in the ON position when a channel has a Red, a Yellow, and a Green signal that turn both On and Off. The channel SSM switch should be placed in the OFF position when an unused Red field output terminal is connected to AC+ or for a channel that does not monitor the Yellow input such as an exclusive Ped channel. -

6.4 BUTTONS 6.4.1 RESET BUTTON Depressing the RESET button resets the SSM-LE series Signal Monitor after it has been triggered by a fault. The monitor remains in the reset mode only if the fault condition has been restored to normal. Depressing the RESET Button while the display is in the PF Data Log, AC Data Log, or Clock Set mode will only reset the display mode to the normal mode. -
