If the OLS 5 foot cable is not long enough to reach the OpenWay Riva Pit 500W ERT Module, an
extension cable is available from Itron (CFG-0151-404). The maximum cable length between
the OpenWay Riva Leak Sensor and the OpenWay Riva Pit 500W ERT Module is 30 feet.
Caution: If the pit module is installed to enable communications for the OLS but a
register is not connected, replace the register connector's cap (2) with the
environmental cap removed from the blue telemetry connector (1) to protect the
register connector.
Optional Remote 500W ERT Disconnect Valve Installation
This section describes installation of a remote 500W ERT disconnect valve in an OpenWay Riva
500W ERT system. The OpenWay Riva 500W ERT module supports three valve states.
■
Connected. The water flow is open and flowing at 100% configured capacity.
■
Disconnected. The water flow is shut off with no water flowing. The remote water
disconnect valve provides the ability to remotely open (reconnect) the valve.
■
Restricted. The water is restricted and flowing at the configured installation flow.
The pit module automatically detects the presence of connected water disconnect devices within
22.5 minutes and begins reading disconnect valve data. To immediately detect the water
disconnect valve and begin reading data, perform a Check ERT with a handheld computer
running FDM software.
The disconnect valve is used in conjunction with both indoor (basement) and outdoor (mounting
on the exterior of the house) pit module installations. Water disconnect devices are mounted on
a water service pipe or meter insetter (meter horn) and connect to the center telemetry
connector (blue) on the pit module. For more information, see Pit module mounting
accessories.
Note: Remote water disconnect operation requires a pit module with enhanced security
enabled.
Installing the Remote 500W ERT Disconnect Valve
The remote 500W ERT disconnect valve ships from the supplier with the Itron cable installed.
See the manufacturer's installation instructions for the procedure to mount the disconnect valve
in the pipe close to the pit module.
Caution: Remote disconnect valves must connect to the telemetry (blue port) of the
module.
