The relay for the dry contact for the transmitter shall be wired to be powered, opening the normally closed contact, the radio transmitter shall transmit normal operation signal to lower area at a set timing interval not to exceed every 5 minutes.

b. When the float indicates an alarm condition the relay for the radio contact shall lose power and the relay shall close indicating an alarm condition to the transmitter, the transmitter shall transmit an alarm signal to the lower area at the set timing interval.

c. Note: Normally closed relay contact is used as a fail safe operation of the upper lift station, such that if the upper lift station loses power, the radio transmitter sends an alarm signal.

3. Setup transmitter to relay alarm condition on/off to lower lift station receiver as appropriate for proper operation as described above.

E. Mount the radio receiver inside the utility building, next to the load center and water system controls powered from a new Square D QO115 breaker and circuit installed within

c. Dump station water supply electronic actuator valve (new) to allow/prevent water flow to the dump station.

1) Install an electronic actuator valve in the dump station water supply line. Size and location as directed by Contracting Officer. Power hold open with spring close, or, power open and close types may be used.

Picture of water supply lines. Contracting Officer to determine which line the actuator valve must be installed in.

SCAT Machine PLC

COMMON WORK RESULTS FOR ELECTRICAL 260500-8

F. Operation, normal operation signal:

1. While the radio receiver gets an upper lift station normal signal, the receiver outputs a signal to the following until an alarm signal is received:

a. Two dry contact closed signals in line with each lower lift station pump controls allowing the pump to operate.

b. An open dry contact signal to the lower lift station alarm light in parallel with the existing alarm light controls.

c. A closed dry contact signal to the dump station water supply actuator valve keeping or turning the valve to the open position.

d. A closed dry contact to a SCAT Machine PLC input allowing the SCAT machine to operate normally.

G. Operation, alarm signal:

1. While the radio receiver gets an upper lift station alarm signal, the receiver outputs a signal to the following until a normal signal is received:

a. Two dry contact open signals in line with each lower lift station pump controls causing the pump to stop operating.

b. A dry contact closed signal to the lower lift station alarm light, in parallel with the existing alarm light controls causing the alarm light to operate.

c. An open dry contact signal to the dump station water supply actuator valve keeping, or similar contact signal turning the valve to the closed position shutting off the water to the dump station only.

d. An open dry contact to a SCAT Machine PLC input Shutting down SCAT machine operation and operating the new alarm light.

H. Power outage operation:

1. Partial power outage: A partial power outage is one that only affects the upper lift station. Upon loss of power at the upper lift station the transmitter will transmit an alarm signal creating the alarm condition in the lower lift station until receipt of the normal signal from the upper lift station. Thus the battery backup for the transmitter at the upper lift station.

2. Full power outage: Well things are shut down anyway, the only difference is that there is not required to be any alarm light notification. No special action required.

I. Note that if another signal method is chosen, it must be approved by the Contracting Officer for demonstration, and shall be demonstrated to work without error in expected weather and partial and full power outage situations.

J. Dry contact ratings: Provided contacts shall be rated capable for not only rated current draws, but for surges caused by making or breaking the currents expected from the various devices, coils, and motors they directly interface with.

1. Provide submittals indicating the rating of the device and the expected inrush and break currents that they will experience when installed.
