KA-710 Automatic Roof Dryer Control
The KA-710 Control Center uses the latest in PLC technology
to control all functions of the automatic roof dryer. All day to day functions are
performed on the switches mounted on the exterior or the weather tight control panel.
There is no need to open the panel door once the dryer controls have been set. These
features include fan 1 and fan 2 start and stop switches, dryer control functions, and a
burner on/off switch. Dryer control operations can be easily monitored through the clear
cover on the control panel. The backlit 4 line LCD visual display module informs the
operator of all functions of the dryer. These displays include time settings, auger delay
settings, fan/heater errors, low grain, full storage and power out conditions. An LED
temperature display continuously informs the operator of the grain temperature. Stainless
steel temperature probes are available in sets of 2 or 4 sensors. A simple set point menu
is standard on all units.
KA-621 Switch
A KA-621 switch (pictured) is mounted at the
top of the grain column to monitor grain level. This reliable, easy to maintain switch is
also used below the drying fan/heater as a full storage monitor of the cooling and storage
compartment of the grain bin.
