There are three options: you can have two independent 4 segment processes (essentially
giving you two recipes) or one 8 segment process.
If you want only one Ramp, use the Stra parameter. You do not have to use the Pu, Tr and
TS parameters.
By using the Stra you are defining the amount of time the controller will take to get the
temperature to the Set Value (time becomes the overriding factor).
If you want more than one R & S, make sure that Stra = 0.
Then choose rsty according to the number of segments desired.
If you want the controller to shut down after it has gone through all the R & S segments, it
must be running in the Manual Mode (Operator Parameters – Run List).
If this parameter is defined as AUTO, then, at the end of the final segment, the controller
will work to keep the temperature at the final target value.
To run the R & S, Rssl in the Operator’s Parameters must be set to RUN via the front
mounted touch pad
OR
via an input module, EMI-700, which can be plugged into the controller. This is further
explained on page 4.

LoL=0EC and P-CL=50% then in temperature P-CL=(1000-0)*50/100=500EC
I-CL Integral time for cooling. (0 to 3600 seconds)
d-CL Derivative time for cooling. (0.0 to 999.9 seconds)
Ct-C Cooling control period. (1 to 150 second)

“SET” button). If the power to the device is removed and reapplied, the device carries out step
response tuning again.
Firstly, the control form must be PID in order for this tuning method to operate.
The user can decide at any
time to use this tuning
method by selecting Atun
or At.St for the tunn
parameter in the run list.
After changing the set
value, if the difference
between the newly defined
and former set values is
greater than the
proportional band
+/-(scale x P-Ht)/1000 if
heating or heating/cooling
or +/-(scale x P-CL)/1000
if cooling, the contoller
will automatically start this
function.
In the event that the actual value moves outside the set value by +/-Strn 3 times while the device is
executing the PID control, the Attn parameter becomes YES and tuning is started.
If the Attn parameter is YES, the device begins tuning from the point where it stands at that moment. If
the heating and cooling PIDs are selected together, or if only the heating PID is selected, Heating Limit
Cycle is performed; if only the cooling PID is selected Cooling Limit Cycle is carried out. If the Limit
Cycle operation can not be completed within 8 hours, tuning is cancelled and the Attn parameter
becomes NO. The PID parameters remain as they were before this failed session.
If Heating Limit Cycle is being done, tuning is performed according to set-((set temperature)/4), if
cooling Limit Cycle is being done, tuning is performed according to set+((set temperature)/4) .
At the end of tuning the Attn parameter becomes NO and the PID parameters are saved to memory.
If a sensor break error occurs, the tuning operation is paused until the sensor connection is re-
established. When the sensor connection returns to normal, the tuning operation is recommenced. If
the Limit Cycle tuning operation can not be completed within 8 hours the tuning operation is cancelled
(the AT LED flashes. The error can be cleared with the “SET” button).
While the tuning operation is under way, the Process Set Value (PSEt) can not be changed.

transformer the Ctr 1 parameter would
be 100/5 or 20
Current Transformer
Calculating set value for heater failure
Set Value = [(Current value without failure +
Current value with heater failure )] / 2
eg. A 200V system with three1KW heaters
would normally draw 15 amps
[1000 / 200 ]*3 = 5A *3 = 15A
If one of the heaters is out of order, the current
draw is now 5A*2 or 10A. The Set Value must
be adjusted to (15+10) /2 or12.5A

In the RUN LIST grouping of the
OPERATOR’s section, select HEAT or
COOL for parameter ULSL.
The parameter can be adjusted
from 5 to 600 seconds. It defines the time
required to open the valve completely.To
determe this parameter correctly, close the
valve manually. Be sure the valve is fully
closed; then reopen it manually without
stopping and measure how long it took to
reopen it completely. Add 5% to this value
and enter it for this parameter.
The parameter determines the
increments as a percentage of the Ultt
parameter and can be adjusted from 0.1 to
5.0 %. If the valve oscillates while opening
or closing, INCREASE this parameter’s
value!
