SPECIFICATIONS : - :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.
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.
The controller is generally part of control panel and in such
a case the terminals should not remain accessible to the
user after installation.
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.
The Controller in its installed state should not be exposed
to carbon dust, salt air, direct sunlight or radiant heat.
Ambient temperature and relative humidity surrounding the
controller must not exceed the maximum specified limit for
proper operation of the controller.
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.
The controller must be wired as per wiring diagram & it
must comply with local electrical regulation.
Care must be taken not to connect AC supplies to low
voltage sensor input.
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.
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.
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.
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.
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.
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.

This parameter will be prompted only if selected control action is PID. It sets
bandwidth over which the output power is adjusted depending upon the error
(SV-PV). The value of this parameter is automatically set by Auto tune function.
This parameter will be prompted only if selected control action is PID. User can
set this value based on process being controlled & type of output being
selected. For Relay O/P, cycle time should be more than 12sec & for SSR O/P,
cycle time should be less than 10sec.
This parameter will be prompted only if selected control action is ON-OFF. It
sets the dead band between ON & OFF switching of the output. Larger value of
hysterisis minimize the number of ON-OFF operation to the load. This
increases life of actuators like contactors but, also produces large errors
(between PV & SV)

In this mode, output (Relay/SSR) remains ON till actual
temperature reaches to the set point. On reaching SP,
output turns OFF & remains OFF till actual temperature
drops down (in heat logic) or raises (in cool logic) equal
to hysterisis set by user.

In this mode, ON & OFF time of

proportionally in every cycle (cycle

PV signal is fluctuating due to noise, increase the filter time constant value.

Function of this parameter is to add/subtract a constant value to the measured PV to
obtain Final PV for control applications. This parameter value needs to be altered for one
of the following reason : -

(ii)To match the display values with another recorder or indicator measuring the same PV.
