EXHIBIT "M" <br />CONFLICT MONITOR CHANGEOUT PROCEDURE <br />Conflict Monitors use NEMA inputs and are interchangeable among manufacturers. <br />TCT LSM12 or LNM12 series monitors must be installed at intersections in TCT closed loop <br />systems for proper operation. TCT LNM12 series monitors must be installed at intersections <br />equipped with PRE-EMPTION. These monitors should normally be reserved for such <br />intersections due to their limited availability. Options on this series of monitor shall not be <br />used unless directed by the Engineer or marked on the timing sheet. <br />1. MINIMUM FLASH TIME set to 10 seconds. The SERIAL and MODEL numbers <br />shall be recorded on the Work Activity Report. <br />2. The intersection should be green for the phase(s) that would flash yellow. If the <br />Technician does not know which Phases flash yellow, he can refer to the <br />Preferentiality listing on the Intersection listing. <br />3. The 10 Amp breaker should be turned 'off. This puts the signal on flash and <br />removes the power from the controller and the conflict monitor. <br />4. The old conflict monitor's MS connector(s) shall be loosened and removed. The <br />conflict monitor program card must be removed and installed in the replacement <br />monitor. <br />5. The new conflict monitor can then be installed in the cabinet and the MS <br />connector(s) connected to the new monitor. <br />6. The 10 Amp breaker can then be turned back on. The controller should reinitialize <br />in the preferential phase. The conflict monitor may have a preexisting "conflict" <br />registered in it's memory and may require a "reset" to get the signal to go to signal. <br />7. If the conflict monitor reinitializes in minor phases, there are other problems not <br />associated with the conflict monitor that should be checked out. <br />S. Record the SERIAL and MODEL numbers of the removed monitor on the Work <br />Activity Report, sign cabinet card showing the time, date and tech performing the <br />conflict monitor exchange. <br />9. Routine Conflict Monitor change outs will be performed within the month listed in <br />Exhibit "B". <br />10. The Annual Monitor Change -out will be performed during the months of October <br />through the end of December. Failed monitors will be delivered to the La Porte <br />District Traffic Office as designated by the Project Supervisor. <br />Page 51 of 53 Pages <br />
