Replacement of Lens and Marking Plate
• Removal
Remove the operator (color lens, marking plate, lens holder, and
spring) by holding the color lens recesses with the Lens Removal
Tool (MT-101) and pulling it out. Remove the marking plate by
disengaging the latches between the color lens and lens holder.
The marking plate must be engraved on the front side as shown
below.
• Note: Make sure that the spring is inserted in the correct
Installation
Place the marking plate on the lens holder in the correct direction,
and press the color lens onto the lens holder to engage the latches.
Put the spring on the lens holder and insert the lens holder into the
housing in the correct direction.
• Installing Non-illuminated Button
Non-illuminated pushbuttons contain a marking plate like illumi-
nated units. Be sure to install the marking plate when replacing the
button.
Replacing the LED Lamp
• Removal
Use the lamp holder tool (OR-66) to remove lamps. Do not use
pliers.
• Installation

Panel Mounting
When mounting the control units onto a panel, use the optional
locking ring wrench (MT-004) to tighten the locking ring. Do not use
pliers. Tightening torque must not exceed 0.29 N·m. Excessive
tightening will damage the locking ring.
Wiring
Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. Sn-Ag-Cu type is recommended when using lead-
free solder. When soldering, do not touch the enabling switch with
the soldering iron. Also ensure that no tensile force is applied to the
terminal. Do not bend the terminal or apply excessive force to the
terminal.
Use a non-corrosive rosin flux.
Installing the Socket
Install the socket on the control unit with the TOP markings on the
control unit and the socket placed in the same direction.
Operating Voltage of LED Lamps
The operating voltage of 5V DC is measured at complete DC. When
using a pulsating voltage such as a full-wave rectification voltage,
keep peak currents within the forward current If. Peak currents
exceeding the If may shorten the LED lamp life.
Other Notes
• Close Proximity Mounting
When mounting pilot lights or illuminated pushbuttons collectively or
lighting them continuously, heat may cause the ambient
temperature to rise above the rated operating temperature. When
the mounting panel is not made of metal or when the control units
are mounted in an enclosed panel, provide for ventilation or lower
the operating voltage.
• Replacement of Buttons (Illuminated/Non-illuminated)
Do not replace buttons of maintained action units while the button is
in the locked position. Replacing the button in the locked position
may damage the internal mechanism. Be sure to release the button
before replacing.
• Operating and Storage Environment
1. Make sure that the operating/storage temperature and humidity
2. Do not use enclosed type units in an environment subject to oil,
• Microswitch Contacts
Do not connect NO and NC contacts of the microswitch to different
voltages or different power sources to prevent a dead short-circuit.
