POWER UP:   

At power on, following sequence will be prompted on the display till it reaches to Home display mode.

In home display mode, by pressing DOWN key, User can 
view the set value of SP1 & SP2 (if OP2 = AUXILIARY or 
ALARM mode) or timer value(if OP2 = soak mode) 
sequentially. 
Here, Lower display will show SP1-value, SP2-value, 
Alarm SP-Value & Timer-value by pressing DOWN key and 
it’s respective parameter code (SP1/SP2/AL.SP/SOAK 
TIME) by pressing UP key.

PROGRAMMING

USER LIST : To access the user list press SET key once.

This parameter is prompted only if output 2 is configured as soak timer. 
Controller  starts  the  execution  of  soak  time  as  per  the  mode  selected. 
Soak timer can be programmed using four different time base in Config. 
List.

This parameter is prompted if SP2 is Enable & output 2 is configured as

(1)

 

Either absolute auxiliary control or as an alarm (High/Low) mode.

(2)

 

Either deviation auxiliary control or as a deviation alarm  mode.

(3)

  As a band alarm(For all above SP2 has to be enable).

User  can  change  SP1  value  using  UP/  DOWN  keys.  Holding  the  key,   
will  change  the  value  at  a  faster  rate.  Press  SET  key  to  store  the 
desired value & move on to the next parameter.

This parameter will be available only if Enabled in Configuration List. 
User can set ramp rate/min for SP1 (Set Point) to minimize overshoot.

This parameter is prompted only if Control Logic for Output1 is 
configured for Heat-Cool.
Output 2 will be automatically activated /de-activated w.r.t SP1 & HYS.

Output 2 will be permanently Activated (ON).

Output 2 will be permanently De-Activated (OFF).

CONTROL LIST : 

SET & DOWN key simultaneously 

To enter in this mode, press 

for 3 sec. User can then set the 

following control parameters.

0.0 %

to

100.0 %

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.

0.5

 to 

100.0 Sec.

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.

to 

300 Sec.

This parameter will be prompted only if selected control action is PID. It 
defines  how  strongly  the  controller  will  react  to  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.

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.

0.5 

to 

99.9°C

This parameter will be prompted only if selected control action is PID. It 
sets  proportional  band  over  which  the  output  power  is  adjusted 
depending  upon  the  error  (SV-PV).  Value  of  this  parameter  is 
automatically set by Auto tune function.

1 to10 

This parameter will be prompted only if selected control action is PID. 
With this parameter  O/P will be Completely OFF after the Set Point + 
Offset Value. If Disable, O/P will act Depending upon the PID Value 
after Set Point achieved.

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.
