Note 1:
In single mode, when power is applied to the
control, Ch1 comes on at adjusted voltage until a logic
input changes the output voltages .
Note 2:
In single mode the control can not “turn off”
both channels at the same time; or “turn on” both
channels at the same time .
Note 3:
When voltage is applied to “Ch2 override”, Ch2
and Ch1 logic inputs are ignored and the outputs are
changed to:
Ch1 = full torque and Ch2 = off .
When power is removed from “Ch2 override”, the control
reads the logic inputs and changes the voltage output
accordingly . If no power is applied to the logic inputs
when power is removed from Ch2 override, then the
output voltages remain at:
Ch 1 = full torque for Ch 1 and Ch2 = Off
Example:
Note 1:
The minimum “on time” or “close time” of each
switch is 10m seconds .
Note 2:
The switches in the above schematics can be
replaced with any kind of dry contact switches; or any
kind of relays . Examples: mechanical relays, momentary
contact switches, toggle switches, transistors, mosfets,
solid state relays, PLC outputs, etc .
Note 3:
The logic inputs of the clutch/brake control are
optically isolated .
