2.2 GENERAL NOTES ABOUT INPUT WIRING
1) Don’t run input wires together with power cables.
2) External components (like zener barriers, etc.)
connected between sensor and input terminals may
cause errors in measurement due to excessive and/or
not balanced line resistance or possible leakage
currents.
3) When a shielded cable is used, it should be

4. CONFIGURATION PROCEDURE

4.1 Introduction
When the instrument is powered, it starts immediately to
work according to the parameters values loaded in its
memory.
The instrument behaviour and its performances are
governed by the value of the memorized parameters.
At the first start up the instrument will use a “default”
parameter set (factory parameter set); this set is a
generic one (e.g. a TC J input is programmed).
We recommend that you modify the parameter set to
suit your application (e.g. set the right input type,
Control strategy, define an alarm, etc.)
To change these parameters you will need to enter the
“Configuration procedure”.


4.1.1 Access levels to the parameter modifications
and their password
The instrument have one complete parameter set.
We call this set “configuration parameter set” (or
“configuration parameters”).
The access to the configuration parameters is protected
by a programmable password (password level 3).
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (E.g. control, alarms, output functions).
Note the instrument will show only the parameters
consistent with the specific hardware and in
accordance with the value assigned to the previous
parameters (e.g. if you set an output as “not used” the
instrument will mask all other parameters related with
this output).


4.2 INSTRUMENT BEHAVIOUR AT POWER UP
At power up the instrument can start in one of the
following mode depending on its configuration:
Auto mode without program functions
- The display will show the measured value
- The decimal figure of the less significant digit is OFF
- The instrument is performing the standard closed loop
control.
Manual mode (OPLO)
- The display will show alternately the measured value
and the message <<OPLO>>.
- The instrument does not perform Automatic control
- The control output is equal to 0% and can be manually
modified by and buttons.
Stand by mode (St.bY)
- The display will show alternately the measured value
and the message <<St.bY>> or <<od>>.
- The instrument does not perform any control (the
control outputs are OFF).
- The instrument is working as an indicator.

Auto mode with automatic program start up
- The display will show one of the following information:
- the measured value
- the operative set point (when it is performing a ramp)
- the time of the segment in progress (when it is
performing a soak).
- the measured value alternate with the message
<<St.bY>>.
- In all cases, the decimal figure of the less significant
digit is lit.
We define all the above described conditions as
“Standard Display”.

4.3.HOW TO ENTER INTO THE CONFIGURATION
MODE
1) Push the P button for more than 3 seconds.
The display will show alternately 0 and << PASS >>.
2) Using and/or buttons set the programmed
password.
NOTES:
a) The factory default password for configuration
parameters is equal to 30.
b) All parameter modification are protected by a time
out. If no button is pressed for more than 10 second
the instrument return automatically back to the
Standard display, the new value of the last selected
parameter is lost and the parameter modification
procedure is closed.
When you desire to remove the time out (e.g. for
the first configuration of an instrument) you can use
a password equal to 1000 plus the programmed
password (e.g. 1000 + 30 [default] = 1030).
It is always possible to end manually the parameter
configuration procedure (see the next paragraph).
c) During parameter modification the instrument
continue to perform the control.
In certain conditions, when a configuration change
can produce a heavy bump to the process, it is
advisable to temporarily stop the controller from
controlling during the programming procedure (its
control output will be Off)
A password equal to 2000 + the programmed value
(e.g. 2000 + 30 = 2030).
The control will restart automatically when the
configuration procedure will be manually closed.
3) Push the P button
If the password is correct the display will show the
acronym of the first parameter group preceded by the

symbol .

In other words the display will show .
The instrument is in configuration mode.


4.4.HOW TO EXIT FROM THE CONFIGURATION
MODE
Push button for more than 5 seconds.
The instrument will come back to the “standard display”
4.5.KEYBOARD FUNCTION DURING PARAMETER
MODIFICATION
A short press allows you to exit from the current
parameter group and select a new parameter
group.
A long press allows you to close the configuration
parameter procedure (the instrument will come
back to the “standard display”).
When the display is showing a group, It allows you
to enter in the selected group.
When the display is showing a parameter, it allows
you to memorize the selected value and to go
to the next parameter within the same group.
it allows you to increase the value of the selected
parameter
it allows you to decrease the value of the selected
parameter
NOTE: The group selection is cyclic as well as the
selection of the parameters in a group.

4.6. FACTORY RESET - DEFAULT PARAMETERS
LOADING PROCEDURE
Some times, e.g. when you re-configure an instrument
previously used for other works or from other people or
when you have made too many errors during configuration
and you decided to re-configure the instrument, it is
possible to restore the factory configuration.
This action allows you to put the instruent in a defined con-
dition (in the same condition it was at the first power up).
The default data are the typical values loaded in the
instrument prior to shipment from factory.
To load the factory default parameter set, proceed as
follows:
1) Press the P button for more than 5 seconds
2) The display will show alternately “PASS” and “0”.
3) By and button set the value -481.
4) Push P button.
5) The instrument will turn OFF all LEDs then it will show
“dFLt” messages and than it turn ON all LEDs of the
display for 2 seconds and than it will restart as for a
new power up.
The procedure is complete.
Note: the complete list of the default parameter is
available in Appendix A.


4.7.ALLCONFIGURATION PARAMETERS
In the following pages we will describe all the parameters
of the instrument. However, the instrument will only show
the parameters applicable to its hardware options in
accordance with the specific instrument configuration (i.e.
setting AL1t [Alarm 1 type] equal to <<nonE>> [not used],
all parameters related with the alarm 1 will be skipped).

[9] oPE - Safety output value
Available: Ever
Range: -100 to 100 % (of the output).
Notes:
- When the instrument is programmed with one control
action only (heat or cool), setting a value outside of the
available output range, the instrument wil use Zero.
E.g. when heat action only has been programmed,
and oPE is equal to -50% (cooling) the instrument will
use the zero value.
- When ON/OFF control is programmed and an out of
range is detected, the instrument will perform the safety
output value using a fixed cycle time equal to 20 seconds.

Notes about digital inputs
1) When diF1 or diF2 (e.g. diF1) are equal to 5 the
instrument operates as follows:
- when the contact is open, the control action is an
heating action and the active set point is SP1.
- when the contact is closed, the control action is a
cooling action and the active set point is SP2.
2) When diF1 is equal to 18, diF2 setting is forced to 18
and diF2 value and cannot perform another
additional function.
3) When diF1 and diF2 are equal to 18, the set point
selection will be in accordance with the following
table
Dig In1 dig.In2 Operative set point
Off Off = Set point 1
On Off = Set point 2
Off On = Set point 3
On On = Set point 4
4) When diF1 is equal to 19, diF2 setting is forced to
up.du and 19 value and cannot perform another
additional function.
5) When a “Sequential set point selection” is used,
every closure of of the logic input increase the value
of SPAT (active set point) of one step.
The selection is cyclic -> SP1 -> SP2 -> SP3 -> SP4

Notes:
- Direct action: the output repeats the status of the
driven element.
Example: the output is an alarm output with direct
action. When the alarm is ON, the relay will be
energized (logic output 1).
- Reverse action: the output status is the opposite of the
status of the driven element.
Example: the output is an alarm output with reverse
action. When the alarm is OFF, the relay will be
energized (logic output 1). This setting is usually named
“fail-safe” and it is generally used in dangerous process
in order to generate an alarm when the instrument power
supply goes OFF or the internal watchdog starts.
