TRIP POINT SETTINGS
The IRU-2XX4/3XX4 has a programmable NPN trip point that is fully program-
mable for ‘BEGIN’ and ‘END’ points and ‘TYPE’ of operation. ( see page 20) The
zero point of distance will be at the transducer, the relay trip points is pro-
grammed in millimeters.
DESCRIPTION PARAMETERS EXPLANATION
Begin Trip Units = millimeters Sets the begin point
Default = of Trip
End Trip Units = millimeters Sets the end point
Default = of Trip
Trip Type Range = 0 - 7 Selects the type of
0 - near function Trip will
1 - exclusive perform. (See Page 20)
2 - hysteresis near
3 - far
4 - inclusive
5 - hysteresis far
6 - disable
Default = 0
To read the Begin Trip Distance in sensor number 1 , use the command structure:
Send Receive
AAh Start Byte 66h Start Byte
01h, Sensor Number 01h Sensor Number
17h Command 17h Command
00h Data (not used) ##h Distance (High Byte)
00h Data (not used) ##h Distance (Low Byte)
55h End Byte ##h NA
99h Stop Byte
To change the Begin trip distance in sensor number 1 to 900mm, use the
command structure;
