Precautions for this product

4Gap-Roller User Manual

1. Introduction
Precautions
when using the GPRThis product (GPR) is a module supporting emergency closure. Pay attention to thefollowing items when using.

Do not use driver cards other than those speciﬁed.

Incorporate the safety circuit (safety relay), etc., and takecountermeasures against malfunction. ⇒ P.15
・In the case of emergency, such as a ﬁre, loss of power
could result in interference with shutter closure if trays
stop on the bridge roller. Take appropriate measures, suchas preparation of an emergency power supply.
⇒ P.15・When an error occurs, eliminate the causes of the error
immediately.
Tray stoppage and/or jam due to an error of the bridge MDR
prevents the shutter from closing. ⇒ P.46
・The GPR has the range of movement. Do not place obstaclesin the range of movement. ⇒ P.23
・Perform settings on [CB-016-MJ2] so that the bridge roller
should not interfere with the ﬁre shutter when it lowers.
⇒ P.38When there are trays on the GPR, do not turn oﬀ the RUN
signal and/or power.
Failure to follow this could result in interference with shutter
closure. ⇒ P.41、P.47
・When turning the RUN signal OFF, the GPR will lower by the dynamic
brake control, and when turning the power OFF, it will lower in thefree falling mode.
・Use the bridge MDR as an auxiliary unit of the front and back conveyors.
⇒ P.39・Check other precautions in each section.

Checking the breaker

Regarding equipment where this product is incorporated, check that a breaker withappropriate capacity for the 24V DC power supply unit has been installed. If abnormal operation should occur, protection through the breaker could be eﬀective.
Note that when using an earth leakage breaker, select one that is “inverter corresponding”. Some inverter non-corresponding earth leakage breakers could result in
malfunction, since they may recognize high-frequency components of the switching
power supply as leakage.

Operation check

When the 24V DC power supply unit has been incorporated, check that the breakerand emergency stop switch can work properly. Perform operation following the trial
operation after checking them.
① AC power input to the DC power supply unit is securely turned ON/OFF whenturning ON/OFF the breaker.
② AC power input to the DC power supply unit is securely turned OFF/ON whenturning ON/OFF the emergency stop switch.

between the frame stay and the swing arm when performing wiring.

B：（1）During wiring, pay attention that the bridge MDR cable does not be pulledwhen moving it between the top and bottom dead centers.
（2）Use cable protective layers to prevent the bridge MDR cable from coming
into contact with the lifting MDR.

CAUTION
Perform wiring when the power is shut oﬀ.
Failure to follow this could result in electric shock and/or accidents due
to unexpected operation.

When attaching or removing connectors, turn oﬀ thepower ﬁrst, securely hold connectors, and perform
operation.
Also, do not apply excessive force to the driver cardconnection parts, such as obliquely attaching or removing
connectors.
Failure to follow this could result in electric shock, malfunction, and/or
accidents due to unexpected operation.

Perform wiring to connectors so that cables make securecontact with connectors.
Barb lines from the cable core could result in heat generation and/or ﬁredue to changes of contact resistance, and/or short circuit with theadjacent contact.

Since cables of the bridge MDR move according to thelifting operation, secure cables appropriately.
Failure to follow this could result in cable disconnection.

7-5.
Trial run
Performing the trial run

Trial run
Perform the trial run with careful attention to the following points, and check that operation iscorrectly performed.
① Check that there is no error (abnormal sound and/or operation failure) when running the GPR.
② Check that there is a distance of 100mm or more to the adjacent conveyor. ⇒ P.23
③ Check that there is a distance of 5mm or more between the bridge roller and the adjacent conveyor
frame. ⇒ P.23
④ Check that there are no structural objects excluding the ﬁre shutter in the GPRʼs movable range. ⇒ P.23
⑤ Check the rotation direction of the lifting MDR. ⇒ P.25
⑥ Check that ﬁxing screws for the frame stay, etc. have not been loosened. ⇒ P.25
⑦ Check that the bridge roller cable has not come into contact with the lifting MDR, as well as that there
is no danger of the bridge roller cable getting stuck and/or caught. ⇒ P.27
■Prevent other devices around the product from activating.
Other devices incorporated in the system, such as conveyor lines, could create
dangerous situations, since trays may start to ﬂow from upstream when the trial run is driven.
Check carefully that other elements in the system will not operate when the productstarts running.
■Make sure to check that wiring, driver card settings, and PLC settings have been carriedout correctly before the trial run.

Repeatedly lift and lower the GPR, and check that there is no error in operation.
■ The GPR may not lower completely depending on the electric brake working
position.

■ Change the dynamic brake working position by the rotary switch on CB-016-MJ2.

3

Check that the GPR will lower when lowering the ﬁre shutter.
Also, check that a space for the ﬁre shutter has been secured.
■ When dividing the power and control for the conveyor, the GPR may not lower
when lowering the ﬁre shutter. To make the GPR operate simultaneously with theﬁre shutter, design the power partition and control for the conveyor.
