Product Description
Maxicom2® Cluster Control Units (CCU)serve as an interface between the central
controller and field satellites (ESP-MC-SATSeries) on the Maxicom2® system. The CCU
acts as the system's “computer-in-the-field,”allowing control of hundreds of sites from
one Central Controller.Schedules are automatically downloaded
from the Central Controller to the Cluster Control Unit at a user-entered time.
Commands are then sent from the CCU tothe appropriate field satellites to control
irrigation throughout the irrigation day. The CCU monitors site conditions constantly
and takes action as needed; managing flow demand, pausing or canceling irrigation in
the event of rain, etc., or locating and isolating the causes of excessive flow
(broken heads or piping breaks). Irrigation
data and information (flow logs, alarms ,actions taken, etc.) are automatically
uploaded to the Central Controller at a user entered time, usually after the irrigation cycle is complete.
The CCU can monitor, communicate to, and manage as many as 28 ESP-Satellite
controllers or other field devices via a two wire (hardwire) or a narrowband link radio
(wireless) communications method
Features:
- CCU-28 operates up to 28 satellites, pulse decoders, or sensor decoders
- CCU-6 operates up to 6 satellites, pulse decoders, or sensor decoders
- LED display that provides current satellite status
- Stores and executes schedule instructions from the central computer
- The CCU utilizes Flo-Watch™ to monitor hydraulic conditions in the field, checking
for breaks in system piping, or valve malfunctions. The CCU will automatically
identify where the problem is located, initiate valve or mainline shutdown to
isolate the problem area, and continue with irrigation for the remaining available
valves. - The CCU utilizes Flo-Manager™ to monitor and sequence valves scheduled
to be turned on, so expected demand does not exceed the hydraulic capacity of
POCs. - The CCU can start, advance, pause, or cancel schedules according to sensor
input (rain, wind, etc) from the field. - Communications activity LEDs show current communications status
- Each unit provides either two-wire or MAXILink™ wireless communication to
satellite controllers and sensors - Anti-rust, corrosion-resistant design UL listed
