Th e M MU -16LE SmartMonitor advantages of the Port 1 SDLC communications to the Controller Unit including Field Check mon itori ng. In this mod e the MMU-16LE SmartMonitor

can operate in a N em a TS -1 config ured cabinet with t h e f ull

ch ann el displays op erate in the Type 12 configuration displaying the Walk input status directly on the associated vehicle channels (2, 4, 6, and 8). Certain requirements exist for this mode to operate correctly:

1. T hi s m od e is li mi te d t o a ma xi mu m of f ou r P ed ph as es which mus t be assigned to vehicl e phases 2, 4, 6, and 8. Th e Walk field t erminals must be wi red to th e MMU-16LE SmartMonitor

connector pins MSA-y, MSA-FF, MSA-EE, and MSA-u respectively. This is conventional wiring for a standard Nema TS-1 cabinet. MMU input TYPE SELECT (pin #HH) must be “open circuit” (False).

2. The C ontrol ler Unit (CU) must be TS-2 Type 2 capabl e and provi de th e Port 1 EIA-485 c ommunic ations port. T he C ontroller Unit must b e config ured f or MM U operation in the following areas (terminology and procedure may vary with different brands of CU):

a. Enable the MMU in the CU Port 1 setup. b. Add the Ped channels to the CU ring structure with the following

3.1 HARDWARE FEATURES

The MMU-16LE SmartMonitor functions and features are firmware programmable which permits upgrades or modific ations b y simply reprogramming the Flash mem ory devic e contai ning th e firmwar e with the upgraded version. Thus, most changes to the MMU-16LE SmartMonitor specif ications m ay b e accommodated without modifying th e har d ware.

Since all critical timing functions are accomplished by the microprocessor, the quartz crystal based accuracy results in very precise and repeatable measurements. This accurac y is mai ntai ned on f uncti ons f rom timi ng faul t c onditions to imp lement ing a uniqu e firmw are based digi tal sampli ng and filt ering alg orithm. This algorit hm is appli ed to all AC field signals to help eliminate false detection in a "noisy" AC line environment.

Input voltages are measured using a true Root Mean Squared (RMS) technique. A dedic ated mic rocontrol ler RMS-Engine samples each AC input voltage at least 32 times per cycle. The RMS-Engine calculates the true RMS voltage value, producing accurate results which are very insensit i v e t o c hanges in frequ ency, ph as e, wav e s hape, an d d is tortion. V ol t a g e r efer e nces are tem per atur e c ompens at ed f or c onst ant vol tag e lev els wit hin t h e op eratin g temper atur e range.

3.7 RECURRENT PULSE DETECTION

This err or detect ion funct i on s u pp lements t h e n ormal Conf lic t, Dual Indic ati on , and Red F ail monitoring algorithms for sensing faults which are intermittent or pulsing in nature. The RMS-Engine

is designed to filter out short term transients commonly found on the electrical service and pr ovi de nois e i mmunity ag ai ns t f alse signal detect i ons . The Recu rr e nt Pulse det ection fu nction is d esigned t o respond t o fault conditi ons whic h are inter mittent in nature and do not meet the continuous timing requirements of the normal detection algorithms, yet may still produce improper signal displays. These input conditions are differentiated by their longer time constant and fault response times.

The f igure bel ow s hows a simple examp le of a Rec urrent Conflic t fault. Channel 2 G reen is detect ed act ive d ue t o a m alfu ncti on of the l oad s witc h whic h c aus ed the out put t o “flic k er” On for 100 ms appr oximat ely ever y 200 ms. Because norm al Conf lict d etecti on requir es a continu ous f ault of at least 350 ms t ypic al, this event c ould g o unde tected. Th e R ecur re nt Pulse det ection algorith m will process th ese pulses i nto one even t and trig ger a Conf lict fault once the longer recurrent timing threshold is exceeded.

When triggered by a recurrent pulse fault condition, the MMU-16LE SmartMonitor

will

enter th e fault mode, tr ansfer t he Output relay c ontacts t o the Fau lt pos ition, and display the approp riate RP CONFLICT, RP DUAL INDICATION, or RP RED FAIL status scr een. The unit wil l rem ain i n t he f ault mod e un til r eset b y the R es et but ton or the E xt ernal R es et input. Faul t respons e times will vary dep ending on the pulse widt h and frequency of the recurrent inputs, but typically range from 1000 ms minimum to 10 seconds maximum.

This f unction c an be dis abled by a UNIT Option called REC URRENT PU LSE in the SET / VIEW CONFIG menu. See Secti on 6.3.4.1.

3.8 TYPE FAULT

The TYP E SE LECT inp ut is us ed b y th e MMU-16LE SmartMonitor

to spec ify whether the

monitor is to be c onfig ured as a Type 16 unit with 16 c hannels or a T S1 comp atible T ype 12 unit with 12 channels (see Section 1.4.2). This input is read by the MMU-16LE

W hen a fault c ondition triggers the MMU-16LE, th e Typ e 0 mes s age inf ormat i on rec ei ved whil e th e f ault c onditi on was being timed will be used by the MMU-16LE SmartMonitor

to determine whether the

T his diagn ostic infor mation is then us ed by the Diagnostic Wizard to is olate wheth er the fault conditi on w as caus ed b y a Con tr oller U nit m alfu nct ion or a failur e i n the load sw itch and/ or field wiri ng. In th e latter cas e, the W izard then pinpoints the f aulty inputs of the ch annels involved in the fault condition.

The Field Check Monitor function is enabled for each channel input individually (see Section 6.3.1) and provi des tw o modes of oper ation, F ield Chec k Fault and Field Chec k

Status.

3.9.1 FIELD CHECK FAULT

In the F ield Check Fault m ode, when th e field signal input st ates sensed as acti ve or inactive by the MMU-16LE SmartMonitor Controller Unit in the Type 0 message for 10 consecutive messages, the MMU-16LE

SmartMonitor

positi on, and display the FIELD CHECK FAULT status screen. The Channel S t at us Dis play will indic ate t he channels on which the F ield Check error was d etected (s ee Section 7.2 Channel S tatus D isplay). B it #67 (S pare Bit #1) of the T ype #129 res ponse f rame will b e set to indic ate a F ield C heck f ault has b een d etected. Th e MMU-16LE SmartMonitor

will

remain in the f ault mode until the unit is reset by the RESET button or the EXTERNAL RESET input. The Field C heck Fail Monitoring function is automatically disabled in the Type 12 mod e, and in th e T ype 1 6 mod e wi th th e POR T 1 D ISAB LE input T ru e (low ). T he Field Ch eck Fail M onitoring f unction is also dis abled when t he RED E NABLE input is not active.

3.9.2 FIELD CHECK STATUS

The Field Check Status mode works in combination with the other fault monitoring functions of the MMU-16LE SmartMonitor

to produce additional diagnostic information

about t he detected fault. The Field C heck Monit or func tion will b e collecting status and timing a Field Check Faul t if t he s ensed fi eld sig nal in put st ates do not c orres pond t o th e Type 0 m essag e data fr om th e Control ler Uni t. W hen a Conf lict, R ed Fail, Clear anc e Fail, or Dual I ndic ation Fai l trigg ers th e MMU-16LE SmartMonitor

, the C hannel St atus Displa y and Main St atus Displ ay will cor respond t o that det ected fault . If Field C heck err ors were detected while the fault was being timed, the Main Status Display will add the text “+ FCstatus” to the fault type, The FIELD CHECK STATUS screen will also be av ailable. Bit #67 (Sp are Bit #1) of the Typ e #12 9 respons e frame will be set to indic ate Fiel d Check errors h av e been d etected.

In a si mp l e example, chan n els 2 and 6 are set to act ive Green by the controller. Chan n el 8 Green is n ot permis s i ve w it h c h annels 2 and 6 and b ec om es act i ve due to a s h ort c ircuit i n the field wiring. The MMU-16LE SmartMonitor

3.11 FLASHING YELLOW ARROW PROTECTED-PERMISSIVE MONITORING (FYA)

The MMU-16LE SmartMonitor

is designed to monitor an intersection with up to four approac hes usi ng th e f our s ecti on Flas hing Yel low A rrow ( FYA) movem ent outlined b y the NCHRP Research Project 3-54 on Protected/Permissive signal displays with Flashing Yellow Arrows . For monitorin g purposes an FYA approach is logically defined as a four input “ch annel” consist in g of t h e s oli d Red Arrow, solid Yel low Arrow, flashing Y ell ow Arrow (permissive), and solid Green Arrow (protected).

- NOTE -

EDI does not provide any guidelines, warrants, or r ecommend atio ns f or th e use of protect ed/permissive left -turn phasing. Th e underlying assum ption is that the traffic engineer has decided that this form of protected/permissive control is the most appropriate left-turn treatment, and all necessary considerations have been made. Until official rulemaking action by the MUTCD has occurred, the operation and functional parameters of the MMU-16LE SmartMonitor® FYA and FYAc modes are subject to change.

Two cabi net c onfigur ations are su pport ed f or bot h t h e M MU T ype 1 6 and T yp e 12 modes depend ing on the number of load switc hes provid ed and the cap abilities of the C ontroller Unit. A Flashing Yellow Arrow approac h is act ually m onit ored usin g two physical channels of t he MMU-16LE SmartMonitor

. In the basic FYA mode of the un it, one additi onal load switch is requi red for each F YA appr oach to b e moni tored. T hus a TS-2 cabi net pr ovidin g four vehicle phases, four pedestrian phases, and four FYA approaches would require sixteen load switches. The compact FYAc mode requires t he Cont roller Unit to remap the Yellow outputs of th e pedestri an load s witch es to dr ive th e prot ected G reen Arr ow sig nals of the FYA ap proach es. I n this mod e the cabin et can pr ovi d e the four FY A approach es with the existing twelve position back panel. Configuration settings are described in Section

6.3.14. In the description of the tw o modes be low, cha nnel numbers are shown for the Type 16 TS-

2 mode of the MMU-16LE SmartMonitor

. Channel n umbers shown in brackets “[ ]”

refer to the respective channels when operating in the Type 12 TS-1 mode (see

Section 1.4.2).

3.11.1 BASIC FYA MODE

The c abinet must b e wired suc h that f or each FYA approach, the solid G reen prot ected Arrow is dr i ven b y a load switc h m on itored on chann els 1, 3, 5 , and 7. Th e associat ed solid Red Arrow, s olid Yell ow Arrow, and flas hing Yellow Arrow (FYA O verlap p hase) must be driven by a load switch monitored on channels 13, 14, 15, and 16 [9, 10, 11, 12] respectively.

6.1 GENERAL

There are s ever al ways to pr ogram the En h anced Func t ion configura ti on param et er s of the MMU-16LE SmartMonitor programmed on the Program Card must be set manually using soldered wire jumpers (Section 6.2). T he MMU-16LE SmartMonitor Card inst al l ed.

Th e m os t b as ic me th od to pr ogram the En hanc ed Funct ion c onfigur ation p aramet ers is t o us e th e fr ont panel menu driven interfac e (See Section 5.2.2.2). The user should select each and every function and provide the required input.

The EDI ECcom software can also be us ed t o d ev el op the configuration parameters. This is the sam e process as using th e front pan el menu dri ven interf ace but is easier du e to the person al comput er int erface. Once a paramet er datab ase has been de veloped , it can be sa v e d t o a disk fi le for later u se or for u se a te mp lat e . Th e p ar am et er datab as e can then be directly downloaded to the MMU-16LE SmartMonitor

6.2 PROGRAM CARD PROGRAMMING

The MMU-16LE SmartMonitor soldered wire jumpers to program the permissive channel pairs, Minimum Flash time, Minimum Yellow Change Disable, +24V Latch Enable, and CVM Latch Enable inputs. The special EDI P rogram Card provided with the unit also has a small non-volatile memory device that contains all the enhanced configuration programming not defined by the standard Nema jumpers.

When replacing the MMU-16LE SmartMonitor standard and enhanced-feature programming is automatically transferred to the replac ement unit when t h e EDI Pr ogr am C ard is ins ert ed and the Unit Option, PGM CARD MEMORY, in the SET / VIEW CONFIG menu has been enabled.

The MMU-16LE SmartMonitor Card and t h e speci al E DI Program C ard. The special EDI Program Card is compatible with all other MM U units that comply with the Nema Publication TS2-2003 v02.06.

6.2.1 PERMISSIVE CHANNEL PROGRAMMING

The MMU-16LE SmartMonitor holes to set the permissive or compatible channel configuration. This programming is determined by the intersection layout and phas e assignments. The card is initially s upplied with 120 empt y wir e jump er h ole pairs . T his initi al program m in g sets all chann els to conflict with all othe r channels. To program a compatible chan nel pair, so lder a wire jumper into the appropriate l ocation for th at c hannel pair as m ark ed on t h e Progr am Card. Make su re t ha t

any jumper l eads do not make co ntact wit h any other jumper lead on the c ard or the monitor chassis when the Programming Card is inserted into the MMU-16LE.

Exampl e: If channel 2 Green and Yellow is PERMISSIVE with ch an nel 4 Green and Yell ow , solder a jumper wire into the jumper pair labeled "2-4".

6.2.2 MINIMUM FLASH TIME PROGRAMMING

The MMU-16LE SmartMonitor

Programming Card contains a group of soldered wire

jumper h ol es to set t h e Mi ni mu m Flashing Indication t im e af t er an MMU P ow er Failur e. The program ming of th e Minimum F lash time is in a binar y encoded f ormat. The additi on of a solder ed wir e j u m p er i n a ju mp er h ol e p air w ill ad d that designat ed i n put value to the bi n ar y weighted sum

plus 1 second (minimum period is 6 seconds). This provides a programming

range from 6 seconds to 16 seconds.

Open Jump Jump Open 7 seconds

Jump Jump Open Jump 14 seconds

It is recommended that the Minimum Flash Time be programmed on the MMU-16LE

SmartMonitor

to facilitate an orderly start-up sequence of the Cabinet Assembly upon

applic ation or r estorat ion of AC LINE p ower. T he amoun t of flash ti me is t ypicall y equal t o the amou nt pr ogr amm ed on th e Con tr oller U nit ( mi nim um 6 s ec onds ). Th e Mi nimu m Fl ash Time should be long enough to ensure all cabin et components are initi alized and read y before the MMU-16LE SmartMonitor

transfers the OUTPUT relay and places the

intersection into operation.

6.2.3 MINIMUM YELLOW CHANGE DISAB LE PROGRAMMING

The MMU-16LE SmartMonitor® Program Card c ontains a grou p of 16 s oldered w ir e j umper holes t o dis able Minimum Yellow Change Monitoring f or each channel. A soldered wire jumper in a jumper hole pair will DISABLE Minimum Yellow Change Monitoring for that channel.

Minimum Yel low Change Monitoring requir es acti vity on all three channel inputs (Green , Yellow, and Red) to detect a Minimum Yellow Change Fault. This function should be disabled for channels which do not provide a true Yellow Change interval equal to or greater than 3 seconds.

6.2.4 VOLTAGE MONITOR LATCH PROG RAM MING

The MMU-16LE SmartMonitor

Program C ard cont ains t w o s old ered wire jumper h ol e p ai rs

to cause +24V Monitor and Controller Voltage Monitor (CVM) faults to be latching. A soldered wire jumper in the jumper hole pair labeled 24V Latch Enable will ENABLE the latching mode for +24V Monitoring. A soldered wire jumper in the jumper hole pair labeled CVM Latc h En abl e w ill ENABLE the latching mode for CVM Monitoring.

If the latch mode is enabled for either of these monitoring functions, the MMU-16LE

SmartMonitor

6.3 ENHANCED FUNCTION PROGRAMMING

The Program Card provides the configuration values for all required basic Nema TS-2 functions (S ec ti on 2). The MMU-16LE SmartMonitor

provides a host of additional functions

that ar e programm ed from the f ront panel menu inter face. Alternatively, the data can be design ed or downloaded fr om disk fi le using th e ECcom sof tware. All Enh anced Func tion 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 Fiel d Chec k monit oring f uncti on (Se e Secti on 3.9) is en abled on a per input basis for each channel. The Field Check function must be enabled for the Diagnostic Wizard to directly pinpoint fa ulty channel inputs.

Typically any monitor input that is driven from a load switch output should have Field Check enabl ed. This woul d inc l ude the Red , Yel low, and Gr een inputs from a veh ic l e ch an nel, Th e Yellow and Gre en inputs from a protect ed-permis sive l eft turn c hannel, and the R ed and Green inputs of a pedestrian channel.

The foll owin g lis t desc ri bes s ever al examp les wh ere th e Fi eld Check function f or that input should be DISABLED.

1. The R ed field si gnal in pu t of a ch ann el is t i ed t o A C LI N E f or t h e l ef t tur n chann el 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 Y ellow fi eld sign al input of a pedes trian ch ann el which is n ot moni torin g t he Yellow l oad swit c h outp ut ( e. g. n o load on Y el l ow ).

4. The R ed field si gnal inp ut of a pedestrian channel which is not monitoring the Don’t Walk load switch output (i.e. the Red (D on’t W alk) field signal input is tied to AC LINE).
