To install the controller select a location where:
o no one may accidentally touch the terminals
o mechanical vibrations are minimal
o corrosive gas is minimal
o temperature can be maintained at about 25˚C to 35˚C and the
fluctuation is minimal
o no direct radiant heat is present
o no magnetic disturbances are caused
o no wind blows against the terminal board
o no water splashed
o no flammable materials are around
Turn off the power to the controller before installing it on the

How to connect wires:
Before carrying out wiring, turn off the power to the
controller and check that the cables to be connected are not alive with
a tester or the like because there is a possibility of electric shock.
NOTE:
o All wiring must confirm to appropriate standards of good practice and
local codes and regulations. Wiring must be suitable for Voltage,
Current and temperature rating of the system.
o Provide power from a single-phase instrument power supply. If there
is a lot of noise in the power line, insert an insulating transformer into
the primary side of the line and use a line filter on the secondary side.
Do not place the primary and secondary power cables close to each
other.
o For thermocouple input, use shielded compensating lead wires for
wiring. For RTD input, use shielded wires that have low conductor
resistance and cause no significant differences in resistance between
the three wires. Do not connect Terminal Number – 3, 6,9,12 when
thermocouple or linear input is selected.
o Use repeater after each set of 32 instruments connected in RS-485
Communication.
o Unused terminals should not be used as jumper points as they may be
internally connected, which may cause damage to the unit.
CAUTION:
High voltage transients may occur when switching inductive loads such
as some contactors or solenoid valves. Through the internal contacts,
these transients may introduce disturbances which could affect the
performance of the instrument.
For this type of load it is highly recommended that a “snubber” is
connected across the normally open contact of the relay switching
though load. The snubber recommended consists of a series connected
resistor/capacitor (typically 15nF/100 Ohms). A snubber will also
prolong the life of the relay contacts. A snubber should also be
connected across the output of a trip output to prevent false triggering
under line transient conditions.

Control Output (ON/OFF Control ) :-
ON/OFF Controller is the simplest form of temperature control device. The output
from the device is either on or off, with no middle state. An on-off controller will
switch the output only when the temperature crosses the set point. For heating
control, the output is on when the temperature is below the set point, and off above
set point.Since the temperature crosses the set point to change the output stage, the
process temperature will be cycling continually, going from below set point to above,
and back below. In cases where this cycling occurs rapidly, and to prevent contactors
and valves from getting damaged, an on-off differential, or “hysteresis,” is added to
the controller operations. This hysteresis assures, if temperature exceed set point by
a certain amount before then only output will turn off or on again. On-Off hysteresis
prevents the output from “chattering” or making fast, continual switches if the
cycling above and below the set point occurs very rapidly.
Relay type High (H-ON):
For High type of set value, once process value reaches up to set point + Hysteresis value,
relay will be ON after few seconds (as per relay delay) and it will be ON until process
value goes down to Set point.
Relay type Low (L-ON):
For Low type of set value, once process value reaches down to set point - Hysteresis
value relay will be ON after nearly few seconds (as per relay delay) and it will be ON until
process value goes up toward Set point.
NOTE:-
8204 has both Control Logic (ON-OFF) & Alarm Logic. If Control Logic (ONOFF) is required, rloP in lvl2 must be selected as Co.
Whenever Control Output(ON-OFF) logic is selected , all relays are mapped
as shown in chapter no.6. As well as, relay latch is off and relay group is
assigned as relay per group 1. In this logic, user cannot change relay
mapping, relay latch and relay group and user cannot acknowledge relays.

9. Calibration Procedure:-
Calibration is provided for ambient temperature, PV sensor input, Retransmission
output.
First select the calibration function as described below and then follow the procedure
depending on the parameter to be calibrated. The sequences of parameters that will
be available for calibration are listed below:
Ambient temperature adjustment
PV Sensor input
Retransmission output (calibration for voltage or current)
Ambient temperature adjustment:-
DATA window shows Amb (Ambient temperature adjusts). If Increment Key is
pressed, DATA window shows, temperature measured by the controller and by
applying old calibration data.
DP of last digit will blink to indicate that the value can be changed. Use Inc/Shift key
to adjust it to desired value. Once the desired value set and press MENU key, the
blinking DP will go off to indicate that the value has been registered. The controller
will automatically save all the new calculations. Ambient temperature adjustment is
over.
Press MENU key to calibrate other parameters or press Escape key to come out to
normal operation.
PV input sensor calibration:-
When user enters in calibration menu, DATA window shows CAL.Z (Calibration
ZERO) for sensor input zero calibration for Thermocouple Linear input and RTD type.
Press Increment Key, DATA window shows as per the Input feed. Feed sensor input
using a calibrator, such that process value is close to lower range value.
Note: The controller allows the user to calibrate sensor‟s input anywhere in the
range, but it is recommended that it should be calibrate the input at points close to
lower and upper range values.
DP of last digit will blink to indicate that the value can be changed. Use Inc/Shift key
to correct the displayed reading to the desired process value and press MENU key.
The controller will display message wait (wait) in the DATA window to indicate that it
is doing the necessary calculations.
When the calculations are over, the new calibration values are stored automatically.
So, Zero calibration is over.
Press MENU key to calibrate other parameters or press Escape key to come out to
normal operation.
DATA window shows the CAL.S (calibration SPAN) for sensor input span calibration
for Thermocouple Linear input and RTD type. Press Increment Key, DATA window
shows as per the Input feed. Feed sensor input using a calibrator, such that process
value is close to sensor‟s upper range value. Use Inc/Shift key to arrive at the
desired process value. Press MENU key to register the changes.
The controller will display message wait (wait) in the DATA window to indicate that it
is doing the necessary calculations. Depending on the situation, this process may
take few seconds to calibrate. Zero and Span calibration is over.

In case, the controller cannot complete the calibration due to any reason, it will hold
previous calibration parameters. Calibration for input sensor is over.
Retransmission output calibration (Voltage/current output) (Optional):-
Press MENU key repeatedly, till DATA window shows message rtr.Z (retransmission
output zero calibration).
DATA window shows the value being outputted on Retransmission output terminals.
Measure the value using a highly accurate digital multi meter. Use Inc/Shift key to
change measured value observed in multi meter on DATA window. Press MENU key.
The controller will store zero calibration value. Press MENU key to calibrate
retransmission output span calibration menu.
DATA window shows the message rtr.S (retransmission output span calibration).
DATA window shows the value being outputted on retransmission output terminals.
Measure the value using a highly accurate digital multi meter. Use Inc/Shift key to
change measured value observed in multi meter on DATA window. Press MENU key.
When the calculations are over, the new calibration values are stored automatically.
Calibration for Retransmission output is over.
Press Escape key to come out to normal operation.
Group Calibration Detail:-
NOTE:

PV INPUT STATUS DISPLAY DURING BURNOUT CONDITION:
Table 1
Note: If set PV_low/PV_high for input type is less then maximum value of zero and
span for then process value will display readings above 5% of display range, then
after it will show oVER/UnDR (OVER/UNDER) message until value crosses maximum
value of Sensor range. OVER/UNDER condition is applicable for TC and RTD
input types only. Process value greater then maximum value of zero/span then
display will show oPEn (OPEN) message. Retransmission o/p(Retransmission is
optional) will follow 5% of display range and then it will give fixed o/p depending up
on OPEN sensor selection. In case of linear inputs scaling is applied then during
OPEN sensor condition it may not show oPEn (OPEN) message instead it will show
either oVER/UnDR (OVER/UNDER).
