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.

Access all menus and to move

button when in the program mode.

Increase the parameter values
and access the program menus.
Decrease the parameter values
and access the program menus.

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-

00, which can be plugged into the

controller. This is further

rStO

From 0 to 50% of SV. (Inactive if 0). If rSto or ramp & soak functions have
been selected, then (set value-rSto)<starting temp<(set value+rSto). The
unit operates within this range for the duration selected.

ULSL

If output module 1 is a relay output, then this parameter can be used to define the
motorized valve control form. Output 1 to open and Output 3 to close the valve:
