Instruction Manual
Thank you for purchasing the controller manufactured by BFC Limited.
Please read this instruction manual thoroughly before use for proper
use of the product.
This instruction manual should be handed to the end user.
1. Before use
About vibrator
Be sure to use the specified piezoelectric feeder (AFR-xxxD,
AFJ-xxxD, AFB-xxxD series).
*This product cannot be used with an electromagnetic feeder.
2. Safety precautions
Precautions are classified into “Danger,” “Warning” and “Caution”
depending on the degree of risk in this instruction manual.
Danger
Hazards are obviously anticipated.
If the product is handled in an improper manner neglecting the
indication, death or serious injury may occur.
Warning
Hazards may occur depending on the situation.
If the product is handled in an improper manner neglecting the
indication, death or serious injury may occur.
Caution
Hazards may occur depending on the situation.
If the product is handled in an improper manner neglecting the
indication, minor or medium-level injury may occur.
The Danger, Warning and Caution below do not cover all possible
cases.
Read the catalog and the instruction manual carefully and place priority
on the safety in performing operations.
Danger
To prevent electrical shock, do not perform operations in live wire
state.
To prevent catching fire, do not use at places with hazardous
objects such as ignitable objects and flammable objects.
*The product is not explosion-proof.
If the product is installed at a high place, it may drop or fall
depending on conditions.
Provide measures against drop and fall. Moreover, retain and fix
firmly in installing the product.
Do not splash water on the product, wash the product or use the
product under water to avoid injury, electrical shock or fire due to
malfunction.
Warning
Shut OFF the power supply before removing the cover.
Be sure to shut OFF the power supply before performing wiring to
avoid electrical shock.
Do not insert/remove the connector while the power supply is ON
or apply unnecessary load on the connector to avoid damage to the
system and electrical shock.
Do not step on the product or put objects on the product to avoid
accidents, falling of the product or damage to the product caused
by dropping or falling of the product.
Do not damage the lead wire to prevent fire or electrical shock
caused by electrical leakage.
Connect a ground before use.
To prevent failure, damage and shortening of the service life, do not
use the product exceeding the specified use range.
Do not use the modified product to avoid failure and damage.
*Failure of the product modified by the customer is not covered by
the warranty regardless of the reasons.
Wiring should be done properly according to the instruction manual
and connections should be checked for mistakes before turning ON
the power supply.
*Mistakes of wiring may cause breakage or malfunction.
Caution
Do not install the product at dusty places because the product is
not dust-proof.
Secure a working space around the installation place of the
product, because failure to perform daily inspections and
maintenance could lead to breakage of the product.
Be sure to disconnect from the controller and ground the bowl or
the chute before welding the bowl or the chute to avoid damage to
the controller caused by leakage current.
Be sure to hold the main body in carrying the product, without lifting
up by holding the cord, to avoid damaged wire or bad connection.
Never run/stop a vibrator to which the power supply to the
input/output side is turned ON/OFF by an electromagnetic switch,
etc. to avoid failure and damage.
*If the vibrator ON/OFF is done frequently, check the external
control method on the instruction manual and perform in a proper
manner.
Install in an adequately ventilated room, avoiding places of high
temperature and humidity.
The ambient temperature should be 0 to 40°C.
Do not remove the labels and stickers.
Dispose the product in a proper manner as an industrial waste.
