B. Contractor shall demonstrate operation and programming of controller.

C. Provide 8 hours of instruction each for two persons, to be conducted at project site with manufacturer's representative.

Description of Operations A. The PLC will be programmed by the Contractor for the following functions.

B. In continuous mode:

1. Push buttons start the trashrake operation. The trashrake cycles continuously between proximity sensors until the selector switch is set to “off” or “auto” position.

2. Stop button will initiate immediate mid-cycle motor stop and system will wait until start or return button is activated. Start button will continue trashrake cycle in the same direction while the return button will return the trashrake to the designated park position.

3. Return button will initiate immediate return of trashrake to the designated park position and wait until start button is again activated.

C. In auto mode:

1. Push buttons start trashrake operation for one cycle to remove initial debris.

System then starts interval countdown. When interval has lapsed, the trashrake is activated for one cycle and the process is repeated until selector switch is set to “off” or “continuous”. User inputs run interval via programmable touch panel.

2. Stop button will initiate immediate mid-cycle motor stop and system will wait until start or return button is activated. Start button will continue trashrake cycle in the same direction while the return button will return the trashrake to the designated park position.

3. Return button will initiate immediate return of trashrake cleaner to the designated park position and wait until start button is again activated.

4. Differential water level sensors will immediately activate trashrake until level setpoints are once again achieved. Interval countdown cycle is not interrupted during this process. Sensor level 1 will initiate the trashrake only while sensor level 2 will initiate autodialer as well as trashrake.

D. In the off mode:

1. Start buttons and touch panel, are by-passed. PLC sends a signal to an “off” indicator light (LED). Trashrake lockout is initiated until selector switch is set to auto or continuous.

E. Changing selector switch to “off” position will initiate immediate return of trashrake to designated park position.

F. Indicator lights (LED) will be utilized for all conditions, run, alarm, auto, and/or stop.

Page 14 of 27 (revised) Attachment A

G. Four spare I/O contact points minimum, 2 input and 2 output, shall be provided for future system monitoring/control.

H. The autodialer will be initiated upon PLC failure giving message to indicate such.

I. The autodialer shall have 2 messages for level 2 sensor alarm. One message shall indicate system running normal and cannot maintain clean the trash rack. The other message shall indicate that due to operator input error, selector switch set but no motor initiation, level 2 alarm has occurred.

J. The autodialer shall also initiate if there is a power failure, giving appropriate message.

K. All timer, interval, and speed values necessary for system control and monitoring shall be user input through the programmable touch panel.

L. The motor drive shall provide alarm conditions to the PLC upon initiation of shutdown or other adverse condition. PLC shall initiate autodialer upon such conditions.

M. The water differential system shall provide real-time water level values to the PLC/user interface. The Contractor shall coordinate with the end user for desired units of measure.

Performance And Design Requirements

A. All components shall be balanced so that jamming at any point will not result in structural failure or tipping of the unit. Provide safety interlocks that will prevent the drive motor from stalling.

B. The rake system shall be inherently stable under unbalanced loads and under external design forces, including wind and seismic. The rake trolley unit shall include integral counter weights that offset unbalanced loads associated with the operation of the rake. The rake trolley unit shall include locking devices that transfer overturning forces to the rails for loading combinations that result in overturning safety margin of less than or equal to 2.
