Safety Precautions
●Do not use the product in an explosive atmosphere, flammable gas atmosphere, corrosive atmosphere, a
place exposed to water splashes, or a place close to combustibles. It may cause an electric shock, injury
and/or fire.
●All work (e.g., installation, connection, operation, maintenance and failure diagnostics) must be done by a
qualified person. Failure to do so may cause a fire, electric shock and/or injury.
●Do not conduct such operations as move, installation, connection, and maintenance while the power is
on. Be sure to conduct such operations after turning off the power in order to be safe injury and/or
accident.
[General]
[Wiring]
[Adjustment / Installation]
●Never touch the power supply when installing PULSE ROLLER or Driver card. It may cause an electric
shock and/or injury.
●Do not touch the internal structure during operation to prevent entanglement and/or clamping accidents.
●Be sure to input instructions such as start/stop, after switching on the power. It may cause an injury
and/or accident due to unexpected start-up.
●If Driver card's protection function worked, remove the cause surely prior to release the function. Other-
wise, malfunction may occur and it will result in an accident, injury and/of breakage.
●If abnormal noises are being given out from the product, turn off the power switch and cut the power
supply immediately to avoid unpredictable accidents.
●Do not use the unit in any way beyond its specifications. It may cause an injury and/or breakage.
WARNING
●Be sure to check the specifications of the power supply (direct current), the voltage (DC24V±5%),
PULSE ROLLER and Driver card before wiring. Failure to do so may cause a fire, electric shock, injury
and breakage.
[Operation]
WARNING
CAUTION
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury and could
cause property damage.
Please strictly comply with the warnings and instructions
contained in this manual to prevent the risk of an accident,
breakage and/or malfunction of the product.

Safety Precautions
[General]
●Do not pull, bend or twist the cord with unnecessary force. There is a danger of a fire or electric shock
due to breakage.
●The DC power supply must be earthed. It may cause an electric shock in case of a breakdown or
electrical leakage.
●When connecting the control device such as PLC to Driver card, they should share a power supply. If the
power supplies are different, install a device like relay between a signal input of a Driver card and the
control device so as to transmit signals.
[Wiring]
[Adjustment / Installation]
[Maintenance]
●Replace with a new part immediately if you discovered damage of the product.

1. Put in the main unit from the under conveyor frames, then securely fasten it to the mounting
hole with supplied screws while supporting.
At this time, align the orientation of the pulley position and the direction of the main unit as
instructed by the drawing. In some cases, the main unit, conveyor, and interlocking roller belt
are possible to interfere one another.
2. Connect the PULSE ROLLERs for lifting/transport with Driver cards in which the programs
were already set.
Make sure that the cards are connected correctly. Failure to do so may lead to malfunction.
3. Connect the upper/lower limit sensors and Driver cards to the power supply and a PLC.
4. After installation, perform a test-run without loading to check whether it operates correctly.
[Notes]
●When an overrun occurs during rotation, PULSE ROLLER for lifting will turn around to its
original position.
At the operation resumption, the timing deviation may occur in ascent movement but it will be
eliminated in a short time. To prevent the deviation, Basic operation on Page 4 is recom-
mended.
●The product size at the upper limit position and the lower limit position might be different from
the size in this manual for reasons of the setting situation or control method.
