SAFETY INSTRUCTION :
This controller is meant for temperature control
applications. It is important to read the manual prior to
installing or commissioning of controller. All safety related
instruction appearing in this manual must be followed to
ensure safety of the operating personnel as well as the
instrument.
GENERAL
v
The controller must be configured correctly for intended
operation. Incorrect configuration could result in damage
to the equipment or the process under control or it may
lead personnel injury.
v
The controller is generally part of control panel and in such
a case the terminals should not remain accessible to the
user after installation.
MECHANICAL
v
The Controller in its installed state must not come in close
poximity to any corrosive/combustible gases, caustic
vapors, oils, steam or any other process by-products.
v
The Controller in its installed state should not be exposed
to carbon dust, salt air, direct sunlight or radiant heat.
v
Ambient temperature and relative humidity surrounding
the controller must not exceed the maximum specified limit
for proper operation of the controller.
v
The controller in its installed state must be protected
against excessive electrostatic or electromagnetic
interferences. Ventilation holes provided on the chassis of
the instrument are meant for thermal dissipation hence
should not be obstructed in the panel.
ELECTRICAL
v
The controller must be wired as per wiring diagram & it
must comply with local electrical regulation.
v
Care must be taken not to connect AC supplies to low
voltage sensor input.
v
Circuit breaker or mains s/w with fuse (275V/1A) must be
installed between power supply and supply terminals to
protect the controller from any possible damage due to
high voltage surges of extended duration.
v
Circuit breaker and appropriate fuses must be used for
driving high voltage loads to protect the controller from
any possible damage due to short circuit on loads.
v
To minimize pickup of electrical noise, the wiring for low
voltage DC and sensor input must be routed away from
high current power cables. Where it is impractical to do
this, use shielded ground at both ends.
v
The controller should not be wired to a 3-Phase supply with
unearthed star connection. Under fault condition such
supply could rise above 264 VAC which will damage the
controller.
v
The Electrical noise generated by switching inductive
loads might create momentary Fluctuation in display,
alarm
latch up, data loss or permanent damage to the instrument.
To reduce this use snubber circuit across the load.
v
It is essential to install a over Temp. Protection device to
avoid any failure of heating system. Apart from spoiling the
product, this could damage the process being controlled.
