Terminal functions are configured over Ethernet interface.
SET1 = RUN input
SET2 = MAX input
SET3 = FB (10.5 V) output, used to supply RUN and MAX inputs. External
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
is turned on.
LED1 and LED2 will show current relay configuration.
Same as Mode 9, with exception of:
module IP address is set to 192.168.0.246
Twin IP address is set to 192.168.0.245
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.
