3. ADJUSTMENT OF SET POINTS:
(a) RATE1 [rat1 ]:
Press key for 2 seconds.
You are in SET MODE.
Display 1 will show rat1.
Display 2 will indicate current value of set point. Range is 0.1 to 9.9°C/min
You can change current value of this set point by following PROCEDURE.
Increase the parameter by key.
Decrease the parameter by key.
Press to store it in memory or press for next step.
If No key is pressed for 5 seconds previous value of parameter is retained and controller goes in control
mode.
(b) SET POINT 1 [Set1]:
Press key for 4 seconds.
You are in SET MODE.
Display 1 will show SEt1.
Display 2 will indicate current value of set point. Range is 0°C to 1200°C
You can change current value of this set point by following PROCEDURE.
Increase the parameter by key.
Decrease the parameter by key.
Press to store it in memory or press for next step.
If No key is pressed for 5 seconds previous value of parameter is retained and controller goes in control
mode.
(c) HOLD TIME [HLd1]:
Press key for 6 seconds.
You are in SET MODE.
Display 1 will show HLd1.
Display 2 will indicate current value of set point. Range is 1 to 999min.
You can change current value of this set point by following PROCEDURE.
Increase the parameter by key.
Decrease the parameter by key.
Press to store it in memory or press for next step.
If No key is pressed for 5 seconds previous value of parameter is retained and controller goes in control
mode.
NOTE: You can do the setting of the remaining parameters Rate2, Setpoint2, Holdtime2 Rate3, Setpoint3,
Holdtime3, Rate4, Setpoint4, Holdtime4, Rate5, Setpoint5, Holdtime5, Rate6, Setpoint6,
Holdtime6, Rate7, Setpoint7, Holdtime7, Rate8, Setpoint8, Holdtime8, & Rate9, Setpoint9,
Holdtime9 just like (a), (b) & (c).
NOTE: Here, the Control Action is On-Off & Hysteresis provided is fixed which is 2°C.
NOTE: Initially as the power is turned on Relay (R2) is turned ON. After completion of hold 9 the
process will be off and r2 goes OFF, when process temperature reaches at ALARM set point
and lower display will show end.
WORKING
1) As the power turns ON upper display shows room temperature/ process temperature and lower
display shows value current temperature, which changes according to the Rate (°C/min).

2) Initially when temperature reaches to the Set value decided, during that period RELAY 1 (R1)
turns ON. When it crosses to the Set value then RELAY R1 becomes OFF. Again when it reaches
SEt - HYS where Hysteresis is fixed 2°C it will turns ON again RELAY (R1).
3) Here, Relay R1 is for controlling purpose. It operates only when temperature reaches to the set
point.
4) By pressing both & keys one can see on the lower display which particular rate or
which particular hold time is going on.
5) Every Higher stage set point is always greater than all its lower stage set point except the last
stage (9) set point. The ninth stage set point can set to any value from 0 to 1200 °C.
Note # 1: When you operate this unit first time, you can freely play with key
to understand key operations, previously set parameter will remain unaffected as long as you
don’t press key.
