6 PNEG-1955 Flex-Flo Control Unit
2. Operation and Maintenance of Flex-Flo Control Unit
Standard Systems
The Flex-Flo Control Unit is primarily controlled by an auxiliary switch, such as a proximity switch or
infrared sensor or hopper level control. Refer to wiring diagrams
on Pages 12-20 that matches the auxiliary
switch used. The auxiliary switch is installed underneath the Flex-Flo Control Unit. The Flex-Flo auger can
only run when the auxiliary switch is calling for feed. If the auxiliary switch fails to shut the Flex-Flo auger
OFF when the feed is full, the feed will build-up inside the box behind the control unit and the safety backup
switch will be activated. As a result, the Flex-Flo auger will shut off until the feed drops away.
Extension Systems
The Flex-Flo Control Unit may also be used to control a fill system auger that feeds into an extension
system auger. In the case of an extension system, there is no auxiliary switch used to control the fill system
auger. If the fill system auger is to be controlled independent of the extension system auger, there must
be a jumper wire across the “Auxiliary” switch terminals marked “Signal IN” and “Signal Out” of the fill
system control unit. Refer to wiring diagram for “Flex-Flo Control Unit Extension System - Independent”
on Page 14 . When wired this way, the fill system auger is controlled by the safety backup switch.
If the fill system auger is to be controlled by the extension system auger, there needs to be a two (2)
conductor cord from the fill system control unit “Auxiliary” terminals marked “Signal IN” and “Signal Out”,
to the extension system control unit terminals marked “Relay Output”. Refer to wiring diagram for
“Flex-Flo Control Unit Extension System - Dependent”
on Page 13 . When wired this way, the fill system
auger is controlled by the extension system control unit.
Indicator Lights Under Toggle Switch
There are two (2) indicator lights on the end of the Flex-Flo Control Unit underneath the toggle switch. The
lower light is green and indicates that the toggle switch is ON and the safety backup switch has not been
activated. The Flex-Flo auger will be allowed to run if the auxiliary switch is calling for feed, when this green
light is ON.
(See Figure 2A.)
The upper light is red and indicates that the toggle switch is ON and the safety backup switch has been
activated. The Flex-Flo auger will not run when this red light is ON.
(See Figure 2B.)
