Safety Precautions
Before installing and using the Safety Mat System, carefully read the instruction manual attached to the product.
!WARNING
Serious injury may occur due to breakdown of safety
outputs. Do not connect loads beyond the rated value
to the safety outputs.
Serious injury may occur due to loss of required
safety functions. Do not use the Safety Mat with logics
that the operation of the mat might turn ON the
guarded equipment. Use the Safety Mat with logics by
which safety outputs turn OFF in a hazardous state.
Serious injury may occur due to loss of required
safety functions. Wire the Safety Mat properly so that
supply voltages or voltages for loads do NOT touch
the safety inputs accidentally or unintentionally.
Serious injury may occur due to loss of required
safety functions. Do not use a Safety Mat to detect
children as it does not support child detection.
To use a Safety Mat for the purpose of entry detection,
secure the following safety distance until a person
reaches a hazardous area by walking on the mat.
Otherwise, the machine may not stop before the
person reaches the hazardous area, causing injury.
Calculation of the Minimum Safety Distance
The EN999 standards provide the following formula to calculate the
minimum safety distance for floor-installed Safety Mats:
S = (1,600 x T) + 1,200 mm
In this equation, S is the minimum safety distance (unit: mm), the
term 1,600 represents a standard approach speed of 1,600 mm/s,
T is the overall stop time required for the machinery to stop, and the
term 1,200 mm represents the length of a step and the length of an
arm.
The overall stop time is comprised of two components:
T = t1 + t2
t1 : Maximum response time from the activation of the detection
device to the point that the control device's output goes OFF
(30 ms for these Safety Mats).
t2 : Response time of the machinery, i.e., the time required to stop
the machine or remove the risk after receiving the output
signal from the Safety Mat System.
Precautions for Safe Use
• Turn OFF the power supply before wiring. Also, do not touch any
terminals (current-carrying parts) while the power is ON. Doing so
may result in electric shock.
• Do not perform wiring when there is a risk of lightning. Doing so
may result in electric shock.
• Apply properly specified voltages to the Safety Mat inputs.
Applying inappropriate voltages cause the Safety Mat to fail to
perform its specified function, which leads to the loss of safety
functions or damages to the Safety Mat.
• Use a power supply of the specified voltage. Do not use power
supplies with large ripples or power supplies that intermittently
generate incorrect voltages.
• Do not use the Safety Mat for a load that exceeds the Safety Mat's
switching capacity (contact voltage, contact current) or other
contact ratings. Doing so will reduce the specified performance,
causing insulation failure, contact welding, and contact failure, and
the Safety Mat may be damaged or burnt.
• The durability of the Safety Mat depends greatly on the switching
conditions. Confirm operation under the actual conditions in which
the Safety Mat will be used. Make sure the number of switching
operations is within the permissible range. If a Safety Mat is used
after performance has deteriorated, it may result in insulation
failure between circuits and burning of the Safety Mat itself.
• Do not use the Safety Mat where flammable gases or explosive
gases may be present. Doing so may cause combustion or
explosion due to Relay heating or arcing during switching.
• Do not drop or disassemble the Safety Mat. Doing so may reduce
the product characteristics and may result in damage, electric
shock, or burning.
• To prevent short-circuit or ground failure of the load, connect
protection elements such as fuses. Not doing so may damage or
burn the load.
• When installing trims, be careful not to get injured by the edge of
the trim, etc.
The worst case scenario for the response time of the machinery
(t2) must be used in the formula. The actual response time
depends on various factors such as the machinery being used, the
operating mode, the product being processed, and the point in the
control cycle at which the stop signal is received. If there are other
factors that may affect the response time, such as brake wear,
these factors must be taken into account as well.
Example Calculation
In this example, the Safety Mats are used with machinery that has a
measured worst-case response time of 0.485 s.
T = t1 + t2
= 30 ms + 485 ms
= 515 ms = 0.515 s
S = (1,600 x 0.515) + 1,200 mm
= 824 + 1,200 mm = 2,024 mm
Consequently, the Safety Mat must be installed at a minimum
distance of 2,024 mm from the danger source.
Note: 1. Read the Instruction Sheet included with the Safety Mat
System thoroughly for details on designing and installing
the Safety Mat System to provide the minimum safety
distance mentioned above.
2. The Safety Mat's Ramp Trim and Molded Corner are not
