From voltages to timings, they actively scan for faults and dangerous situations that could arise from loyalty equipment and electrical shorts. As a safety feature, they will trigger a flash situation at an intersection to notify a technician of an undesirable or unsafe operation, and also act as a safety warning for motorists. Annual testing is required by many agencies and often requires certification documents for records. These documents may be requested for legal purposes involving a motor vehicle accident. For this reason it is important to have the correct procedure for the setup and testing of said equipment.

Special care must be taken when reinstalling a monitor after testing to make ere the configuration matches the potential faults at any particular intersection. There are two main tools that will be used during testing. First is the hardware, or the PACT-2600, which will be used to simulate various faults and measure response times for acceptable values. The second tool is the PACT-26TH software. This graphic user interface will be used to configure the hardware for various tests, conflict monitor makes/models, and testing standards. This booklet will be discussing several aspects of conflict monitor testing.

The equipment used, initial setup, testing procedure, and conflict monitor tenting. Any other information or details not described within this document can be found in the manufacturers operations manual. Testing Hardware Testing of conflict monitors will be done using the PACT-2600. All conflict model testers must be professionally calibrated each year to ensure that all tests are performed with accuracy. You can check the front of the unit for a certification sticker that states when it was last calibrated. It is important that calibration has occurred with the calendar year, or testing could produce false results.

We will be discussing the different parts associated with this tester, ND later, the operation of the unit. The first piece is the unit itself. You should first notice the five ports on the front of the unit. Starting left to right, there is the serial port, the A output, B output, C output, and D output. The serial port uses a standard DB male to female straight connector. This will be used to connect a laptop with running the PACT-2600 software to the unit. The next outputs, A, B, C, and D, will be used to connect the appropriate testing cable for the correct monitor being tested.

To the right of the unit there is a power switch and two fuses, which prevent electrical shorts from imaging the unit. The next important parts are the test cables. The 210/225/2010/2070 test cable is the most frequently used. This cable IS used for testing of 2010 style monitors found in our 1 70 cabinets. There are four output cables that are labeled A, B, C, and D. These will connect to the outputs on the front of the PACT-2600 unit. You will also find cables for testing ENEMA MUMS. These are used to test 3, 6, and 12 channel MUMS in ENEMA style cabinets. Outputs are also labeled to match the outputs on the front of the PACT;2600 unit.

There is also a power conditioner used in conjunction with the PACT-2600. This unit will ensure that a steady 120 volts of clean power will be supplied to the testing unit. This is a very important part of the operation, as the unit will not test correctly unless it has good, clean power. You’ll notice that the PACT-2600 is directly plugged into the power conditioning unit. Tests Eng Software Testing of 201 0 and ENEMA style conflict monitors will be done using the PACT-26TH GIG. This program has several options for testing, labeling and creating certification sheets for record keeping.

The PACT software requires the use of an IBM compatible PC with Microsoft Windows XP or later. Below s a basic startup screen you will see when opening the program. Settings and testing procedures will be covered later in the handbook. Types of Conflict Monitors City of Fort Collins uses several different brands Of conflict monitors, which will be described next. There are two basic types, 2010 and ENEMA. 2010 monitors are used in 1 70 style cabinets with various configurations. ENEMA monitors run in ENEMA cabinets and come in 3, 6, and 12 channel configurations. 201 0 Monitors CUTS 2010 The most basic monitor is the CUTS 2010 monitor.

It has 16 channels and minimal display capabilities. It uses a standard 2010 program card, which is interchangeable with many other 2010 monitors. In most cases, the serial number for this model can be found on the bottom side of the program card bay. The diversities for setting the monitor are located underneath the program card. Dip switches will allow you to choose which channels to monitor at any given intersection. This style of monitor however, cannot be used at an intersection running a flashing yellow arrow configuration. EDI CELL/CECIL The EDI 2010 CELL/CECIL functions very similar to the CUTS 2010, but has added features and settings.

The first most noticeable is the front display. This model is able to show not only which channel is active, but which color as well. The serial number for this model is usually located on a sticker, just on top of the program card bay. The program card used for this monitor is also a standard 2010 program card. The diversities are located at the back of the program card bay. These allow for the function off FAY configuration and other advanced features to be described later. You might also notice the WAD toggle switch located on the top of the program card bay.

This switch is for the Watch Dog function, and must always be switched to the ON position. RENO 201 8 Although RENO monitors are setup differently than the previous monitors mentioned, they still function in the same basic principles. RENO monitors are capable of monitoring 18 channels as opposed to 16. The diversities are located on top of the program card bay. You might also notice the WAD toggle switch located on the top of the program card bay. This switch is for the Watch Dog function, and must always be switched to the ON position. Special steps must be taken when testing these monitors or they will fail testing.

This requires resetting the monitor manually after power is applied. Channel These monitors can have different manufacturers, but all will function the same. These are usually found at pedestrian crossing intersections running ENEMA cabinets. They do not have program cards and have minimal setup required. Diversities are provided on the front of the unit for programming. When testing these use the 3 channel testing cable. 6 Channel 6 Channel conflict monitors use a ENEMA program card. These cards are different from the 201 0 standard and are not interchangeable. Two types are currently installed in the field.

The first is the SMELL-P. This model has an LCD screen and diversities on the front for configuration. The second type is the INS-AL. This model is a very basic model with only a dial on the front for setting startup flash time. Both of these will use the same type of program card. They also require a 6 channel testing cable. 12 Channel There are two types of 12 channel monitors, both using a ENEMA program card. The LCD-APP is the simpler of the two, with diversities on the front for programming. The more complex 500 series, has an LCD interface, and a keypad for programming allowable phases and timings.

These monitors require a 12 channel testing cable. Initial Setup . Put the On / Off switch located on the front of the PACT in the Off position. 2. Connect the male end of the DB serial cable to the connector labeled “Serial Port” on the front of the PACT. 3. Connect the female end of the DB serial cable to your computer serial port. 4. Connect the monitor cable connectors to the correspondingly labeled female connectors on the front of the PACT. 5. DO NOT turn the On / Off switch to the On position until the monitor connectors are connected to the monitor.

On both ENEMA ITS and ENEMA TTS monitors, insure that the program card is blank when running a basic Certification test. Refer to Monitor Switch Settings for additional help with the conflict monitor’s extended feature switches. System 170 Model 2010 monitors should not have any diodes cut (permissive) or Yellow inhibits on the programming board for Certification Testing. You should test the monitor with a “clean” programming card for Certification Testing. This will result in a record that all monitor functions described in the standard were working on all channels at the time of the test.

On 201 0 type monitors, the SMS diversities need to be in the ON position for all channels, regardless of intersection phasing. Be sure to write down the initial settings of these diversities so they can be returned after testing. If testing a FAY enabled monitor, the FAY COMPACT switch must be turned off. Once you have verified that the monitor settings are correct, plug the monitor cable circular MS style con nectars into the corresponding connector on the monitor (ENEMA monitors) or insert the monitor into the monitor cable edge card connector (210, 2010 monitors).

Finally, verify that the PACT has been setup as described earlier and then you may turn the On / Off switch located on the front of the PACT to the On position. At this point, you should hear here beeps from the PACT and then the sound of a small motor moving for about 10 seconds. You are now ready to begin testing. Note : If you do not hear three beeps and the sound of a motor moving for about 10 seconds when the PACT is power is turned on, there may be a problem with the unit. In some cases the cause for this was a bad cabinet ground or unclean power.

Power down PACT and check cabinet for ground and clean power. Testing Procedure Now that you have followed the initial setup it’s time to open the PACT-2600 software to begin testing. Upon opening the software, you will be presented with a screen similar to this Monitor Standard- This is where you select the conflict monitor standard you wish to test. For 2010 model monitors, select Cultural Model 2010. For ENEMA style monitors, select ENEMA ITS . Monitor Type- Now select the number of channels you will be testing. For 2010 model monitors select 16 Channel.

For ENEMA style monitors, select either 3 Channel, 6 Channel, or 12 Channel. Manufacturer- From the drop down list, select the appropriate manufacturer of the monitor you will be testing. Model- Here you will select the model of the monitor you will be testing. Serial Number- Locate the serial number on he conflict monitor and input it here. Device ID- Leave this field blank. Location- Find the intersection and place it here. If testing in the shop, use shop. Tested By- Place your name here. Agency- Use Fort Collins. Certification Click on the next tab, Certification.

Here you will see this screen. Run Option tests- You will notice that the Run Optional tests box is checked and the three optional tests are present in the List of selected optional tests. This will ensure the PACT will run the three optional tests for Short YELL, LEGEND / SEND Isolation, and AC Line Brownout. Short YELL will test the monitor for short yellow timings. LEGEND / SEND Isolation verifies that the earth ground and logic ground are not shorted together in monitor. AC Line Brownout verifies that the monitor can recognize AC line brownout and restore voltages.
