CONTROL LIST: To enter in this mode press SET & DOWN key simultaneously for 3 sec.

Parameter	Display	Range	Description	Default
Lock Code		1 – 9999	Set this parameter to 15 (Default LOCK CODE) to access Control List. User has a choice to set different Lock Code via USER LOCK CODE in Config. List.	15
Propor tional Band		0.5 to 99.9°C	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.	5.0°C
Integral Time		0 to 9999 Sec.	This parameter will be prompted only if selected control action is PID. It sets the time taken by PID algorithm to remove steady state error. Value of this parameter is automatically set by Auto Tune function. If set to ‘0’, this function will be disabled.	240
Derivative Time		0 to 300 Sec.	This parameter will be prompted only if selected control action is PID. It defines how strongly the Controller will react to the rate of change of PV. Value of this parameter is automatically set by Auto Tune function. If set to ‘0’, this function will be disabled.	60
Cycle Time		0.5 0.User to 99.9 Sec.	This parameter will be prompted only if selected control action is PID. can set this value based on process being controlled & type of Output being selected. For Relay 0/P, cycle time should be more 12sec & for SSR 0/P, cycle time should be less than lOsec.	16.0 Sec.
Output Power Limit		0% to 100 %	This parameter will be prompted only if selected control action is PID. This parameter will decide the maximum output power in % applied to the load.	100%
Output Off		1 to 10	This parameter will be prompted only if selected control action is PID. With this parameter 0/P will be Completely OFF after the Set Point + Offset Value. If Disable, 0/P will act Depending upon the PID Value after Set Point achieved.	Disable
Tune Offset		50 % to 100 %	This parameter will be prompted only if selected control action is PID. This parameter allows the User to carry out Auto Tuning function below the set point. (If Tune offset is 50 % tuning will be carried out at 50 % of the set point and if 100 % tuning will be carried out at 100% of the set point.)	100%
Control Hys.		1 to 25°C	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 of load.This increases life of actuators like contactors but also produces large errors (between PV & SV).	2°C
Delay		0 to 500 Sec.	This parameter will be prompted only if selected control action is ON-OFF. It sets the main output restart time where 0/P once turned OFF will turn ON only after restart time, regardless difference between PV & SP in Heat or Cool mode. If set to ‘0’, 0/P will be switched without delay. Also, Delay will be applicable in case of every power ON.	0 Sec.

Temp Type		°C : If selected, the instrument will display the temperature in °C.					°C
		°F : If selected, the instrument will display the temperature in °F.
Lower LiSmit		Sets the minimum limit for set point adjustment. It can be set from minimum specified range of selected sensor to HSPL value. 0 C					°
Higher SP Limit		Sets the maximum limit for set point adjustment. It can be set from LSPL value to maximum specified range of selected sensor.					° 400 400°C
Process Value Offset		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 can be altered : (i) To compensate for known thermal gradient. (ii)To match the display values with another recorder or indicator measuring the same PV.					0°C
Input Filter		The controller is equipped with an adaptive digital filter which is used to filter out any extraneous pulses on the PV. The filtered PV Value is used for all PV dependent functions. If the PV signal is fluctuating due to noise, increase the filter time constant value.
Control Mode		User can select between PID or ON-OFF action algorithm to be adopted for output.					PID
Control Logic For Output		This parameter will be prompted only if selected control mode is ON-OFF. User can select heating logic in which OP1 will remain ON till PV < SR (PV increases when output is ON.)					Heat
		This parameter will appear only if selected control mode is ON-OFF. User can select cooling logic in which OP1 will remain ON till PV > SR (PV decreases when output is ON.)
Output Type		User has to set this parameter very carefully in accordance with the output used. (Separate terminal for RELAY & SSR, Refer electrical installation ) Select Relay if LOAD is connected via contactor. Whenever user selects Relay, Cycle time will automatically get set to 16 sec.					Relay
		Select SSR if LOAD is connected via SSR (DC voltage pulses). Whenever user selects SSR, Cycle time will automatically get set to 1sec. User can modify cycle time via control list.
Overshoot Control Point		This parameter will be prompted only if selected control action is PID. Setting this parameter on higher side will proportionally slows down the rate of rise of PV to minimize overshoot (this may cause delay to reach SP). Disabling or Setting this parameter on lower side will proportionally increase the rate of rise of PV ( which may cause overshoot). Disable this option if delay is not required to reach SP. (This may cause overshoot w.r.t. SP)					. Disable
Auto Tune		This parameter will be prompted only if selected control action is PID. If Enabled, this parameter will be prompted if user press Shift key for 3Sec.
		If Disabled, this parameter will not be prompted if user press Shift key for 3Sec.					Enable

		If disabled, User can not View or edit Set Point (SP1) in USER list.
User Lock Code		Default USER LOCK CODE is 15 to access Control & Configuration List. User has a choice to set its own USER LOCK CODE between 1 to 9999, this is to prevent unauthorized access of Control & Configuration List.	15

AUTO TUNING MODE: To enter in this mode, Press & hold SHIFT key for minimum 3 sec in Run Mode.

Parameter	Display	Description	Default
Auto Tuning Mode		This function will be executed only if selected control action is PID. Auto-tuning function is enabled by setting this parameter to ‘YES’. The decimal of LSB flashes till Auto tuning function is in progress. During Auto-tuning, Controller learns the process characteristics by itself & calculates required P, I & D values. User can cancel or abort this feature by setting this parameter to ‘NO’.	No

USER GUIDE:

ON-OFF ACTION: In this mode, Output (Relay/SSR) remains ON till actual temperature reaches to the set point value. 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. (As shown in Fig : 3.1 & 3.2)

AUTO TUNING MODE: In this mode, Controller learns the process characteristics by itself and calculates the required P,I & D values. It can be performed at any time after power ON but, it is best to start it when the process is at Ambient temperature in order to minimize overshoot & undershoot. Auto tuning is applied in case of :

1. Initial set up for a new process.
2. Substantial change in SP from previous auto tuning value.
3. Control accuracy is not satisfactory.
   If the control performance by using auto-tuning is still unsatisfactory, User can apply the further adjustments of P,I & D values as shown below

Adjust	Symptom	Solution
Proportional Band	Slow Response	Decrease PB
	Over Shoot or Oscillations	Increase PB
Integral Time	Slow Response	Decrease Int
	Instability or Oscillation	Increase Int
Derivative Time	Slow Response or Oscillation	Decrease Dt
	High Over Shoot	Increase Dt
