Installation
■ Controller
・
Install the controller unit according to “1-3 Installation Method” , assuring
plenty of space around it. If it is installed in a manner other than specified,
failures may occur due to temperature rise.
・
If the controller is mounted internally on the place where air circulation is
blocked such as in a control board, the ambient temperature will rise due to
heat generated by the controller. In such case, forced cooling is required.
・
Vent holes for heat radiation are provided at the top and bottom of controller
unit. Provide adequate space for heat radiation, not to block the holes.
■ Wire Connections and Connectors
• Connect all wirings securely according to the explanations for I/O circuit
and description on the unit.
• Turn off the power of controller before connecting or disconnecting the
connectors.
• When connecting or disconnecting the connectors, be sure to hold the
connector area not to apply extra force to the cable.
• Be careful not to touch terminals or to let foreign objects get in the
connector after disconnecting connectors.
• Be careful not to apply force to around the connector of sensor head cable
and extension cable. Do not bend the cables near connectors, which causes
disconnection of the cable.
• When moving the sensor head during operation, install not to bend the cable
during movement. Use replaceable extensions cable where the cable needs
to be bent.
■ Cable Extension
• Do not pull the cable with a force
more than 29.4N when wiring the
cable when the sensor head and the
controller are fixed. At least 20
mm is required from the cable
connection to the bend. The
bending radius must be 30 mm or
more.
• Use only one extension cable for
connection between one sensor head
and a controller.
20mm or more
R30mm or more
