2.2 General notes about wiring
1. Do not 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 connected at
one point only.
4. Pay attention to the line resistance; a high line resistance
may cause measurement errors.

5 CONFIGURATION PROCEDURE
5.1 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 performance are governed
by the value of the stored 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).
WARNING! Before connecting the output actuators,
we recommend to configure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).
WARNING! Do not change the [6] Unit (Engineering Unit)
value during process control as the temperature
values inserted by the user (thresholds, limits etc.)
are not automatically rescaled by the instrument.
To change these parameters you need to enter the
“Configuration mode”.
5.2 Instrument behaviour at
Power ON
At power ON the instrument can start in one of the following
mode depending on its configuration:
Auto mode without program functions.
–The upper display will show the measured value;
–The lower display will show the Set point value;
–The decimal figure of the less significant digit of the lower
display is OFF;
–The instrument is performing the standard closed loop control.
Stand by mode (St.bY).
–The upper display will show the measured value;
–The lower display will show alternately the set point 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.
We define all the above described conditions as “Standard
Display”.
5.3 How to enter the
“Configuration mode”
1.1 Complete configuration procedure
The configuration parameters are collected in various
groups. Every group defines all parameters related with a
specific function (e.g.: control, alarms, output functions).
1. Push the button for more than 5 seconds. The upper
display will show PASS while the lower display will show 0.
2. Using and buttons set the programmed password.
Notes: 1. The factory default password for configuration
parameters is equal to 30.
2. 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
(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 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 upper display shows:
]inp
(group of the Input parameters).
The instrument is in configuration mode.
5.4 How to exit the
“Configuration mode”
Push button for more than 5 seconds, the instrument will
come back to the “standard display”.
5.5 Keyboard functions during
parameter changing
A short press allows 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 upper display is showing a group and the
lower display is blank, this key allows to enter in the
selected group.
When the upper display is showing a parameter and
the lower display is showing its value, this key allows
to store the selected value for the current parameter
and access the next parameter within the same group.
Allows to increase the value of the selected parameter.
Allows to decrease the value of the selected parameter.
+ These two keys allow to return to the previous
group. Proceed as follows:
Push the button and maintaining the pressure,
then push the button; release both the buttons.
Note: The group selection is cyclic as well as the selection
of the parameters in a group.
5.6 Factory reset - default parameters
loading procedure
Sometime, 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 to put the instrument in a defined
condition (the same it was at the first power ON).
The default data are those typical values loaded in the
instrument prior to ship it from factory.
To load the factory default parameter set, proceed as follows:
1. Press the button for more than 5 seconds. The upper
display will show PASS while the lower display shows 0;
2. Using and buttons set the value -481;
3. Push button;
4. The instrument will turn OFF all LEDs for a few seconds,
then the upper display will show dFLt (default) and then

Ascon Tecnologic - KM1E - Wine - ENGINEERING MANUAL - PAG. 6
all LEDs are turned ON for 2 seconds. At this point the
instrument restarts as for a new power ON.
The procedure is complete.
Note: The complete list of the default parameters is available
in Appendix A.
5.7 Configuring all the 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] to nonE [not used], all parameters related to
alarm 1 will be skipped).

energized (logic output 1).
2. Reverse action: the output status is the opposite
of the status of the driven element.
E.g.
: 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.

[29] Ab1 - Alarm 1 function
Available: When [28] AL1t is different from nonE.
Range: 0... 15 with the following rule:
+1 Not active at power up;
+2 Latched alarm (manual reset);
+4 Acknowledgeable alarm;
+8 Relative alarm not active at set point change.
E.g.: Setting Ab1 equal to 5 (1+4) the alarm 1 will be “not
active at power up” and “Acknowledgeable”.
Notes: 1. The “not active at power up” selection allows to
inhibit the alarm function at instrument power up
or when the instrument detects a transfer from:
• Manual mode (oplo) to auto mode;
• Stand-by mode to auto mode.
The alarm will be automatically enabled when the
measured value reaches, for the first time, the
alarm threshold ±hysteresis (in other words, when
the initial alarm condition disappears).

[33] HAL1 - Alarm 1 hysteresis
Available: When [28] AL1t is different from nonE or
[28] AL1t is different from SE.br.
Range: 1... 9999 engineering units.
Notes: 1. The hysteresis value is the difference between
the Alarm threshold value and the point the Alarm
automatically resets.
2. When the alarm threshold plus or minus the
hysteresis is out of input range, the instrument will
not be able to reset the alarm.
E.g.: Input range 0... 1000 (mBar).
–Set point equal to 900 (mBar);
–Deviation low alarm equal to 50 (mBar);
–Hysteresis equal to 160 (mBar) the theoretical reset point is
900 - 50 + 160 = 1010 (mBar) but this value is out of range.
The reset can be made only by turning the instrument
OFF, removing the condition that generate the alarm and
then turn the instrument ON again.
–All band alarms use the same hysteresis value for both
thresholds;
–When the hysteresis of a band alarm is bigger than the
programmed band, the instrument will not be able to reset
the alarm.
E.g.: Input range 0... 500 (°C).
–Set point equal to 250 (°C);
–Relative band alarm;
–Low threshold equal to 10 (°C);
–High threshold equal to 10 (°C);
–Hysteresis equal to 25 (°C).

]LbA group - Loop break alarm
General note about LBA alarm
The LBA operate as follows: applying the 100% of the power
output to a process, the process variable, after a time due to the
process inertia, begins to change in a known direction (increases
for an heating action or decreases for a cooling action).
E.g.: If I apply 100% of the power output to a furnace, the
temperature must go up unless one of the component in the
loop is faulty (heater, sensor, power supply, fuse, etc...)
The same philosophy can be applied to the minimum power.
In our example, when I turn OFF the power to a furnace, the
temperature must go down, if not the SSR is in short circuit,
the valve is jammed, etc..
LBA function is automatically enabled when the PID requires
the maximum or the minimum power.
When the process response is slower than the programmed
limit the instrument generates an alarm.
Notes: 1. When the instrument is in manual mode, the LBA
function is disabled.
