Safety Precautions - Omron D40B Datasheet

Safety Precautions

!WARNING
Be sure to turn OFF the power before performing wiring.
Do not touch charge parts (e.g., terminals) while power is
ON. Doing so may result in electric shock.
Do not allow the actuator to come close to the switch with
the door open. Doing so may cause machinery to start
operating and may result in injury.
!CAUTION
Use guard stops in the way shown below to ensure that
the switch and actuator do not make contact when the
guard door is closed.

Application Precautions
• Do not use the product in locations subject to explosive or
flammable gases.
• Do not use load currents exceeding the rated value.
• Be sure to wire each conductor correctly.
• Be sure to confirm correct operation after completing mounting and
adjustment.
• Do not drop or attempt to disassemble the product.
• Be sure to use the correct combination of switch and actuator.
• Use a power supply of the specified voltage. Do not use power
supplies with large ripples or power supplies that intermittently
generate incorrect voltages.
• Capacitors are consumable and require regular maintenance and
inspection.
Precautions for Safe Use
Mounting Direction of Switch and Actuator
The Sensor will not operate properly if the switch and actuator come
towards each other diagonally. The Sensor will, however, operate
properly if the switch and actuator come towards each other head-
on, horizontally or vertically (as long as the faces have the same
orientation).

CORRECT INCORRECT
Mutual Interference
If the switch and actuator are mounted in parallel, be sure to
separate them by at least 25 mm, as shown below.

Using for Hinged Doors
On hinged doors, install the Sensor at an opening edge as shown
below.

Switching Power Supply Voltage (D40B-J2 Only)
• Turn OFF the power to the Controller.
• Open the Controller's front cover with a flat-bladed screwdriver.
• Change the power supply voltage as required with the internal
power supply selection switch. The switch is factory-set to
230 VAC.
Fuse Replacement Method
(D40B-J2 Only)
Note: The D40B-J1 has an automatic recovery mechanism and so fuse
replacement is not necessary.
• Turn OFF the power to the Controller.
• Open the Controller's front cover with a flat-bladed screwdriver.
• Replace the fuse (D9M-P1). (See page 198.)
Applicable Safety Category (EN954-1)
This product can be used in environments classified as Safety
Category 3 according to the requirements of European standard
EN954-1. This evaluation, however, is based on circuit configuration
examples proposed by OMRON. The standard may not apply in
some operating conditions.
The applicable safety category is determined from the whole safety
control system. Make sure that the whole safety control system
meets EN954-1 requirements.
Handling
Do not drop the product or subject it to excessive shocks or vibration.
Doing so may result in faults or malfunctions.
