voltage source can also be used.
RS-485 = Modbus interface.
SET1 = RUN input
SET2 = SPEED input
SET3 = FB (10.5 V) output, used to supply RUN and MAX inputs. External
5-24 V voltage source can also be used.
RS-485 = Modbus interface
Reserved for future or customer specific use.
LED1 and LED2 will show relay configuration.
Relay configuration will be increased (0->1, 1->2, 2->0) when electricity

This mode will set communication interface to default values. Main
purpose is to restore default settings.
NOTE:

Disconnect any SET1, SET2 and SET3 connections when using
this mode to prevent possible harm to controller. SET1, SET2,
SET3 will output test voltages of 10 V, 7 V and 5 V respectively.
RS-485 port is actively driven. Relay will cycle. This is used for
testing purposes.

It is recommended that all module wires are disconnected to
prevent possible harm to external controllers.
