Step 7. Installation
(1) Transmitter Installation
LE/LME series Signal Tower
(1-1) Mounting the transmitter onto the Signal Tower
For the Signal Tower that requires a WDT Installation, mount the WDT transmitter after the settings are already
prepared, to the Signal Tower.
CAUTION
Prohibited
◆
Do not overtighten the center screw.
(Tightening Torque: 0.2 to 0.3Nm)
Overtightening the screw may result in operational defects such as internal damage or lamps
flickering.
◆
If oil or other matter adheres to the center screw, wipe it thoroughly before use.
Failure to follow this instruction could result in product failure.
(1-2) Wiring the Signal Tower to equipment
- Wiring is necessary to constantly supply power to the transmitter.
- Wiring is necessary even if the Signal Tower is not being replaced.
CAUTION
Enforced
◆
Constant WDT power supply
To operate the WDT, you need to constantly supply power to the LME/LE series signal tower's
power line.
To connect the power supply, wire the supply to a signal wire of a lamp color that is not in use
(initial value is white) so that it is constantly on.
- Wiring is necessary even if the Signal Tower is not being replaced.
◆
For the 24 VDC specification, do not connect the white wire to the same polarity as the
power supply's yellow wire.
◆
When using transistor control for the 24 VDC type, beware of the white wire polarity.
The power supply wire color for the LE series 24 VDC specification is black.
