Connecting sensing units to control units
1.
Install the wire end of the FF-LSKA0611 (RS485) cable into the control unit housing through its terminal gland.
2.
Connect the wires of the RS485 cable to the control unit circuit board terminals as shown in Figure 4-1.
3.
Install the cable connector end of the RS485 cable to the sensing unit.
IMPROPER GROUNDING OF THE SENSORS
Ensure the shield termination at the sensor end of the RS485 interface cable is
connected to the mounting bracket through the bracket fixing screw.
Failure to comply with these instructions could result in death or serious injury.
The RS485 cable may be cut to meet specific customer application needs.
IMPROPER GROUNDING OF THE CONTROL UNIT
Ensure terminal number 7 in the control unit is connected to ground.
Failure to comply with these instructions could result in death or serious injury.
IMPROPER WIREWAY
Ensure the RS485 signal cable is kept away from power lines. Use different wire routes to bring power and signal to the
control unit.
IMPROPER CONNECTION BETWEEN SENSING UNIT AND CONTROL UNIT
Always use FF-LSKA0611 (RS485) cable to ensure a proper connection between a sensing unit and a control unit.
If damaged, replace the FF-LSKA0611 cable immediately. Do not try to repair the cable or extend its length.
Failure to comply with these instructions could result in death or serious injury.
