Front Panel Description
Entering Process Set Value and Parameters
Setting the process values:
When the
button is pressed, the SV LED, next to the process value on the bottom
!
display, flashes. Adjust the desired process set value using the
and
buttons.
!
!
Press the
button again to save the new value to memory. If, instead, the
!
!
button is pressed, the new set value isn’t saved to memory and the unit exits the
setting mode.
You can't change the SV value when the AT LED is lit.
Setting the alarm values:
All outputs on the device can be configured as alarms. Alarm set values are shown
as
ALr1
,
ALr2
and
ALr3
in the
SET LIST
menu. To access the
Set Lıst
menu press the
button then the
button. Pressing the
button agaın allows you to
!
!
!
access and change the values of
PSEt
,
ALr1
,
ALr2
and
ALr3
.
Observing and changing parameter values:
The parameters have been divided into three groups: Operator, Technician and
Calibration. The calibration parameters can be accessed by the manufacturer only.
The operator can not access the parameters for running mode and configuration.
Whenever you want to enter either the operator’s or technician’s parameter groups,
the device will require a password. The default value of the user-changeable
passwords ıs “0”. To enter new passwords, you must first access the technician’s
parameters and scroll to “PASS ConF”. After entering the password press the
!
button to save it to memory.
You can access the main titles of the menu by using the
and
buttons. Press
!
!
the
button to move to the next level of any menu. Change the value of your
!
chosen parameter by using
and
buttons. The new value is saved to
!
!
memory by using the
Button.

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-
7
00, which can be plugged into the
controller. This is further
explained on page
