Installation / Operation Instructions
CMF Power Select Ver. 3.0
REV 6.32
1 Introduction
1.1 The CMF Power Select is a semi automatic hydro-electric positioning system for the CMF
"TH" (Turn Head), “HH” (Head House), and “Pendulum” series distributors. The heart of
this system is a micro PLC (Programmable Logic Controller) that controls and tracks the
movement and location of the inner spout. The PLC accepts input from the operator via
a 3.5” touch screen HMI (Human Machine Interface) at the operator panel.Once a
position is selected by the operator, the PLC compares the destination to the current
location and determines a direction of travel selecting the shortest route on full round
models. At this point, the PLC engages the hydraulic system and raises the inner spout.
Once the inner spout is raised, it then rotates to the position selected by the operator and
lowers into the outlet stub. The CMF Power Select incorporates several operation,
safety, and diagnostic routines into the programming to inform the operator of the current
status via the HMI at the operator panel.
1.2 From a controls standpoint, all of the CMF series distributors are identical. This allows
for simple integration of multiple units at the same facility.The following sections
describe how to install various configurations of the Power Select and how to operate and
maintain the system.
1.3 This version of the Power Select has multiple options for controlling and monitoring the
unit. The default setup uses a standard Ethernet connection directly from the HMI to the
Power Select. Other options include, but are not necessarily limited to:
•Controlling the Power Select without the HMI
•Connecting the Power Select and HMI to an Ethernet network for remote
monitoring / control
•Controlling more than one Power Select using only one HMI (the HMI can be
easily programmed for multiple units and scaled with the touch of a button)
•Other connections (see section 5)
Note: Any configuration other than the default 1:1 connection will require connections through
an Ethernet switch. The recommended max length of any single run of Ethernet is 320’
although it has been known to function without issues at longer distances. One way to easily
add more length to Ethernet is to install an unmanaged switch at the first 320’ and continue from
there.
