1-3 Safety Precautions
To ensure the most effective and extended use of all equipment, adhere to the following precautions:
☆
Handling of tool
Tools can generate a large amount of torque during operation, and the reaction force is applied to the
Operator or mounting area of the tool. Therefore, tools must be installed in the proper positions and
with adequate reaction devices. Tools MUST be mounted either using their supplied mounting plate
or clamped only in designated areas of the tool or tool damage may result.
Keep in mind that the fastening tool is a strain gage based instrument and, although it has been
designed to withstand sudden shock, repeated shock (over time) could damage some components.
Therefore, support devices must be used whenever practical to ease in handling and operation of the
Fastening Tool.
☆
Fastening
Avoid fastening beyond the full scale torque. Do not use a duty cycle (the ratio of the tool “On” time
to Tool “Off” time) higher than 50%, even when the torque is below the full scale value.
☆
Cable Connection
•
Use the specified/supplied cables for all system connections.
•
Completely lock the tool cable twist lock connectors.
•
PLC I/O cables must be run separate from any high voltage power sources or cabling, and must
not exceed 50 feet in length.
•
GROUNDING of the controller is REQUIRED (Perform Class 3 grounding)
– Make sure the
controllers power cable ground pin is connected to a proper ground or DANGER OF ELECTRICAL
SHOCK EXISTS. Supply primary power with a cable no SMALLER than 1.25mm
2
(17AWG) or the
source voltage may drop below 80VAC and a Suply Voltage Abnormal may occur.
☆
Installation Environment
•
Controller units must be located a minimum of 600 mm from high transient voltage sources such as
transformers, motor starters, AC inverters and AC contactors. If it cannot be avoided, the units must be
properly shielded.
DO NOT use at the following locations.
•
Areas under direct sunlight.
•
Areas where the environmental temperature is out of the 32 °~122°F (0° ~ 45°C) range.
•
Areas where the relative humidity is below the 20% range.
•
Areas where the relative humidity is above the 90% range.
•
Areas where the temperature changes quickly, which may cause condensation.
•
Areas where conductive powder, oil mist, saline, or organic solvents exist.
•
Areas that have corrosive or combustible gases.
•
Areas that have strong electric or magnetic fields.
•
Areas where a strong vibration or shock could be transmitted directly to a Controller unit or tool.
☆
Static Electricity
Since the controller is composed of many electronic components including surface mount devices
(SMD), please be aware of static electricity. Excessive static electricity may occur at dry locations,
therefore we recommend the operator to touch grounded metal before operating the front panel
operation switches to discharge the static electricity charged inside the human body.
