3.11 ACCEPTANCE TEST
A. General: Subsequent to Field Functional Test and instrument calibration, verifying substantial completion of field installation and start-up, the system will be given a final 30-day acceptance test. The 30-day test must be successfully completed, including resolution of punch-list items generated during the test period, prior to the date of substantial completion of the entire project. The system must run continuously for 30 consecutive days. During this period, all system functions shall be exercised, and any system interruption and accompanying component, subsystem, or program failure shall be logged for cause of failure, as well as time of occurrence and duration of each failure.
The Contractor shall provide a competently trained technician or programmer on call during all normal working days and hours from the start of the acceptance test until final acceptance of the system.
B. Testing: The systems to be tested on-line will include general operations as well as Remote Diagnostic Software Programs, PLC Configuration and Uploading/Downloading Programs, the Report Generator and Operation as specified herein. Each system function, e.g., status report-backs, logs, and displays shall be exercised several times at a minimum, and in a manner which approximates "normal" system operation. Failure of the system during the above program testing shall be considered as indicating that the programs and operating system do not meet the requirements of the specifications and corrective action shall be required before restarting the acceptance test. Only those components, subsystems, and systems covered in this specification shall be considered for this acceptance test. Problems and failures of other systems shall not be considered as part of this test (except as they display the capabilities of this system to detect failures).
C. Failures: Failures shall be classified as either major or minor. A minor failure would be a small and non-critical component failure, which can be corrected by the City operators.
This occurrence shall be logged but shall not be reason enough for stopping the test and shall not be grounds for non-acceptance. However, should the same or similar component failure occur repeatedly, this may be considered as grounds for nonacceptance. A major failure shall be considered to have occurred when a component, subsystem, or program fault causes a halt in operation of the system and/or when a technician's work is required to make a repair or to re-initiate operation of the system. A major failure shall cause termination of the acceptance test. When the causes of a major failure have been corrected, a new acceptance test with a new 30-day duration shall be started.
D. Technician Report: Each time a technician is required to respond to a system malfunction, he or she must complete a report which shall include details concerning the nature of the complaint or malfunction and the resulting repair action required and taken.
If a malfunction occurs which clears itself or which the operator on duty is able to correct, no report shall be required (logged as specified above). If a technician has performed work but no report is written, then a major failure shall be considered to have occurred.
Each report shall be as specified above). Each report shall be submitted within 24 hours to the Owner.

The submersible transducers shall be as specified in Section 40 72 13.
2. An excess differential head signal across the screens shall initiate a cleaning cycle.
D. General Operational Description
1. The gripper cleans the screen section by section, returning to the dump area to discharge its load after each cleaned section.
2. The system may be operated automatically or manually. Automatic Operation may be started by one of the following:
a. By depressing the start pushbutton on the local control panel b. By the time clock in the main control panel
c. By the differential level controls
3. When the start command is given, the trolley shall traverse towards the first raking position. As the trolley approaches the raking position, a proximity switch senses the first pick-up plate and the traverse motor stops.
4. After a preset delay the hoist motor is switched on and the gripper is lowered down the screen.
5. The correct depth is sensed by the rotating arm in the trolley actuating the proximity switch and the hoist motor stops. If the proximity switch fails to stop the hoist motor, the mechanical limit switch is actuated and a fault is indicated. If the gripper encounters an obstruction before it reaches the bottom of the screen, the slack rope device actuates a proximity switch which then operates in the same way as the lower limit switch. Again, if the switch fails, a mechanical back up switch is actuated, and a fault is indicated.
6. When the hoist motor stops, either under control from the lower limit or slack rope proximity switches, the hydraulic valve to the gripper cylinders moves to close, the hydraulic motor starts, and the gripper is closed.
7. When the cylinders are fully closed, the increase in hydraulic pressure actuates a bypass, the hydraulic motor stops and the hoist motor starts. If the correct fluid level is not maintained, a fail lamp shows on the control panel. A failure is also indicated if the cycle time is exceeded.
Project Owner AUTOMATIC TROLLEY-MOUNTED TRASH SCREEN RAKE New River Improvement Project – Calexico 41 24 00 - 10
8. As the gripper enters the swing restrictor plates on the trolley, the upper hoist proximity switch is actuated, the hoist motor is stopped, and the traverse motor starts toward the dump area. If the proximity switch fails a mechanical back up switch is actuated, and a fault is indicated. As the gripper approaches the selected dump area, the proximity switch on the trolley detects the sensing plate and the traverse motor stops. The hydraulic control valve moves to the open position, the hydraulic motor starts, and the gripper opens.
9. When the cylinder(s) reaches the full open position, the hydraulic pump stops and resets the traverse.
10. The cycle is repeated and trolley proceeds to the next programmed raking position.
When all programmed positions have been raked, the trolley will traverse and then stop at the “Park” position.
E. System Operation - Automatic
1. The automatic controls of the bar screen cleaner shall be as follows:
a. Programmable for set frequencies of operation overriding the differential level controls.
b. An adjustable time delay from the “start” signal during which time [both visual and audible alarms shall operate.
F. System Operation - Manual
1. Manual Operation shall be performed by depressing the appropriate momentary contact pushbutton on the remote.
2. The operator moves the trolley and gripper out along the track until it is properly positioned above the selected area or bar screen to be serviced.
3. The operator then verifies the gripper teeth are open and then proceeds to lower the gripper. As the gripper descends, the rear teeth shall engage with the screen bars near the top of the Bar Screen. As the gripper continues to descend, accumulations of debris shall be collected into the “jaws” of the gripper until the invert elevation is reached where lowering shall automatically cease. The operator may now close the gripper and raise it along with accumulated screenings to a point above deck level where raising shall automatically cease.
4. With the gripper at fullest height, the operator may now traverse the trolley to the predetermined dumpsite. When the operator verifies that the gripper is properly positioned over the dump area, the operator may open the gripper to dump the contents.
5. The operator will then traverse the gripper to the next cleaning position and repeat the previous steps. When all the positions have been cleaned, the gripper may be returned to the predetermined “Park” position until the next cleaning cycle is required.
6. The system shall incorporate several safety functions as follows:
a. If a large quantity of debris or other obstruction prevents the gripper from descending to the invert elevation, a “Slack Rope” limit switch shall cease the lowering motion.
The gripper may then be closed, raised and the debris taken to the dump area. b. Limit switches shall be fitted to each end of the track to prevent inadvertent overtravel. c. If hydraulic fluid level is not maintained, a “Hydraulic Failure” will be indicated at the main panel.

This test shall be conducted until three (3) successful consecutive tests are achieved.
2. Test 2: The contractor shall park the trolley at the respective dumpsite and lower the trolley to the ground elevation to verify that the lowering operating shall cease upon the trolley resting on the ground and providing a slack rope situation. The gripper shall then be raised to its fullest height to verify the hoist shall stop upward motion upon rising to Project Owner AUTOMATIC TROLLEY-MOUNTED TRASH SCREEN RAKE New River Improvement Project – Calexico 41 24 00 - 12
the proper height. This test shall be conducted until five (5) successful consecutive tests are achieved.
3. Test 3: The contractor shall test the opening and closing capabilities of the gripper and verify it shall fully open and close as required. This test shall be conducted until five (5) consecutive test have been achieved.
4. Test 4: The contractor shall test the automatic modes of each system separately as follows: the system shall be switched to “automatic” and the 24-hour timer prevented from engaging. Each set (separately) of upstream transducers shall have objects placed below the sensor to provide a false differential. The test shall verify that the trolley properly parks over each bar screen, the gripper lowers, closes and raises, the trolley returns to the dumpsite, the gripper opens, then returns to the next bar screen until all or the respective bar screens have been cycled through. Each transducer set shall be tested separately at least one (1) time.
5. Test 5: The contractor shall engage the time clock to prove that the system shall cycle through the entire set of bar screens. Time clock shall be tested at least once or until one successful test is achieved.
