Safety Precautions
CAUTION
Do not touch the terminals while power is being supplied. Doing so may
occasionally result in minor injury due to electric shock.
Do not allow pieces of metal, wire clippings, or fine metallic shavings or
filings from installation to enter the product. Doing so may occasionally
result in electric shock, fire, or malfunction.
Do not use the product where subject to flammable or explosive gas.
Otherwise, minor injury from explosion may occasionally occur.
Never disassemble, modify, or repair the product or touch any of the
internal parts. Minor electric shock, fire, or malfunction may occasionally
occur.
CAUTION - Risk of Fire and Electric Shock
a) This product is UL listed as Open Type Process Control Equipment. It
must be mounted in an enclosure that does not allow fire to escape
externally.
b) More than one disconnect switch may be required to de-energize the
equipment before servicing the product.
c) Signal inputs are SELV, limited energy.*1
d) Caution: To reduce the risk of fire or electric shock, do not
interconnect the outputs of different Class 2 circuits.*2
If the output relays are used past their life expectancy, contact fusing or
burning may occasionally occur. Always consider the application
conditions and use the output relays within their rated load and electrical
life expectancy. The life expectancy of output relays varies considerably
with the output load and switching conditions.
Loose screws may occasionally result in fire. Tighten terminal screws to
the specified torque (E5CSV: 0.74 to 0.90 N·m, E5CS-U: 0.5 N·m).
Unexpected operation may result in equipment damage or accidents if the
settings are not appropriate for the controlled system. Set the
Temperature Controller as follows:
・
Set the parameters of the Temperature Controller so that they are
appropriate for the controlled system.
・
Turn the power supply to the Temperature Controller OFF before
changing any switch setting. Switch settings are read only when the
power supply is turned ON.
・
Make sure that the INIT switch in the control mode switches is turned
OFF before operating the Temperature Controller.
A malfunction in the Temperature Controller may occasionally make
control operations impossible or prevent alarm outputs, resulting in
property damage. To maintain safety in the event of malfunction of the
Temperature Controller, take appropriate safety measures, such as
installing a monitoring device on a separate line.
Faulty terminal contact or decreased waterproofing capability may
result in a fire or equipment malfunction. When inserting the
Temperature Controller into the rear case after setting the switches,
check the watertight packing and make sure that the top and bottom
hooks are locked securely in place. (E5CSV only.)
*1: A SELV circuit is one separated from the power supply with double insulation or reinforced insulation,
that does not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.
*2: A class 2 power supply is one tested and certified by UL as having the current and voltage of the
secondary output restricted to specific levels.
