Controller Bidding Specifications

stop all operating stations and monitor for any high flows. If flow is measured and exceeds
the mainline break threshold see expected controller behavior above. If no flow is measured,
the controller will post a station high flow alert for the stations that operated and move to the
next station(s) in the program sequence. The individual stations with the high flow alert will
be posted on both the controller and web software.
oA No Flow alert is triggered when a station is scheduled to operate and the No Flow
threshold value and delay periods are exceeded.This may be a result of a pump station
failing to start, a closed isolation valve in the mainline, a closed remote control valve or shut-
off backflow preventer. The controller will immediately post a No Flow alert for the
corresponding station(s) and move to the next station(s) in the program sequence. If three
or more successive stations are flagged as No-Flow, the controller will suspend remaining
irrigation and also immediately post a No-Flow alert to the controller and to the web
application.
oContinuous monitoring for leaks during non-scheduled irrigation or during soak periods
when no other scheduled irrigation is operating. When the user-defined threshold value and
delay period is exceeded, an alert notification is posted on the controller and the web
application, but the master valve is not closed until the high flow threshold is exceeded.
Scheduled irrigation continues and the leak notification will continue to appear until the leak
is repaired or until the threshold value is increased or leak detection is turned “Off”.
oExtended Leak offers an additional time delay for irrigations systems utilizing normally open
master valves. When leak detection threshold and extended leak delay period is exceeded,
the controller will immediately close a normally open master valve, post a Leak Alert and
suspend all scheduled irrigation unless a station is operated manually or until the next
scheduled start time. If the leak stops before the delay period expires, the controller will
reset and continue to watch for leak detection. If the leak appears again exceeded the leak
detect threshold and delay period a new leak detect alert will be posted.
2.4 Optional Controller Features
The WeatherTRAK ET Pro3 offers the following:
•Flow monitoring capability when used with a Data Industrial IR-220 Series, Creative Flow
Sensor Technologies (CST) and Netafim Flow Sensing products.
•Compatibility with normally-closed rain, wind, freeze sensors capable of overriding all scheduled
programming functions when activated. Compatible with Toro, Irritrol and Hunter models.
•Compatibility with normally open or normally closed master valves with or without a flow meter
that is user-defined in the Setup menu. The maximum allowable holding current of compatible
master valves is 1000 mA to avoid station over-current valve alerts.
•A pump start can be assign to any available station output when needed. This assignment can
be done outside of Max Active stations and once it’s assigned, it will no longer have any station
programming attributes.
•A single or up to three programs can be excluded from a pump start when not required. Any
station assigned to a program excluded from a pump start will operate without a pump being
actuated from the controller. This feature will only function for pump starts that are electrically
actuated from a controller not mechanically actuated such as a pressure or flow switch.
•The WeatherTRAK ET Pro3 series has direct compatibility with RainMasterTM Pro-Max UA
Series when used with an EX32 cable assembly (purchased separately) and TRCTM
“Commander” or “Sidekick” handheld remotes by simply connecting to a 32-pin connector as a
standard feature to each 24-station input / output board.
oControllers incorporating pump starts will require the station assigned as a pump start to
be operated manually from the controller as part of using a hand-held remote.
oControllers incorporating normally closed master valves can be operated from either
compatible hand-held remote or by selecting a user-defined time length using the
“Maintenance Timeout “feature found in the MANUAL menu on the controller.
•An optional AC input surge protection kit can be ordered for locations where incidences of
lightning strikes or dirty power are high.
