SAFETY INSTRUCTION

This controller is meant for Batch & Length counter 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
proximity 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
e x c e s s i v e e l e c t r o s t a t i c o r e l e c t r o m a g n e t i c i n t e r f e r e n c e s .
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
extended duration.
v Circuit
breaker
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
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
or permanent damage to the instrument. To reduce this use snubber
circuit across the load.
