6.3 ENHANCED FUNCTION PROGRAMMING
The Program Card provides the configuration values for all required basic Nema TS-2
functions (Section 2). The MMU-16LE
SmartMonitor
®
provides a host of additional functions
that are programmed from the front panel menu interface. Alternatively, the data can be
designed or downloaded from disk file using the ECcom software. All Enhanced Function
programming values are simultaneously stored in the non-volatile memory on the EDI
Program Card (see Section 6.3.4.6).
6.3.1 FIELD CHECK ENABLE PROGRAMMING
Menu Path:
MENU / SET VIEW CONFIG / FIELD CHECK ENABLE
The Field Check monitoring function (See Section 3.9) is enabled on a per input basis for
each channel. The Field Check function must be enabled for the Diagnostic Wizard to
directly pinpoint faulty channel inputs.
Typically any monitor input that is driven from a load switch output should have Field Check
enabled. This would include the Red, Yellow, and Green inputs from a vehicle channel, The
Yellow and Green inputs from a protected-permissive left turn channel, and the Red and
Green inputs of a pedestrian channel.
The following list describes several examples where the Field Check function for that input
should be DISABLED.
1.
The Red field signal input of a channel is tied to AC LINE for the left turn channel
of a four or five section signal head.
2.
The Red field signal input of a channel is tied to AC LINE for an unused channel.
3.
The Yellow field signal input of a pedestrian channel which is not monitoring the
Yellow load switch output (e.g. no load on Yellow).
4.
The Red field signal input of a pedestrian channel which is not monitoring the
Don’t Walk load switch output (i.e. the Red (Don’t Walk) field signal input
is tied
to AC LINE).
5.
A separate MMU-16LE
SmartMonitor
®
channel is monitoring an overlap signal
which is generated in hardware from another vehicle channel load switch output.
6.3.2 DUAL INDICATION ENABLE PROGRAMMING
Menu Path: MENU / SET VIEW CONFIG / DUAL IND ENABLE / R-G DUAL ENABLE
Menu Path: MENU / SET VIEW CONFIG / DUAL IND ENABLE / R-Y DUAL ENABLE
Menu Path: MENU / SET VIEW CONFIG / DUAL IND ENABLE / G-Y DUAL ENABLE
The Dual Indication monitoring function (See Section 3.2) is enabled on a per channel
basis for each combination of Dual Indication monitoring; Red+Green, Red+Yellow, and
Green+Yellow. When Dual Indication monitoring is enabled for a channel, the MMU-16LE
SmartMonitor
®
will enter the fault mode when it has detected more than one active input on
that channel. Dual Indication monitoring is typically not enabled for monitor channels that
are not used, or channels that have the Red input (protected / permissive left turn) tied to
AC Line, or pedestrian channels with the Don’t Walk (Red) input tied to AC Line.
6.3.3 RED FAIL ENABLE PROGRAMMING
Menu Path: MENU / SET VIEW CONFIG / RED FAIL ENABLE
The Red Fail monitoring function (See Section 2.2) is enabled on a per channel basis.
When Red Fail monitoring is enabled for a channel, the MMU-16LE
SmartMonitor
®
will
enter the fault mode when it does not detect at least one active input on a channel. Red
Fail monitoring is typically not enabled for monitor channels that are not used, or channels
that do not have an active Red input (protected / permissive left turn), or pedestrian
channels with no active Yellow input.
