ramp, until the time “SSt” is reached or until the power overcomes
the power calculated by the PID controller.
SSt
- SOFT START TIME (for PID control only): Duration time in
hours and min. of the Soft-Start described on pa. “St.P”.
To disable the Soft-Start function set par. “SSt” = OFF.

PAn” (PARAMETERS RELATIVE TO THE USER
INTERFACE) : This contains the parameters relative to the key
U and display functions.
Usrb -
KEY U FUNCTION : Decides which function is associated to
key U. The possible selections are :
= noF : no function
= tunE : Pushing the key for 1 sec. at least, it is possible to
activate/deactivate the Auto-tuning or the Self-tuning
= OPLO : Pushing the key for 1 sec. at least, it is possible to swap
from the automatic control (rEG) to the manual one (OPLO) and vice
versa.
= Aac : Pushing the key for 1 sec. at least, it is possible to
acknowledge the alarm.
= ASi : Pushing the key for 1 sec. at least, it is possible to
acknowledge an active alarm
= CHSP : Pushing the key for 1 sec. at least, it is possible to select
one of the 4 pre-programmed Set Points on rotation.
= OFF : Pushing the key for 1 sec. at least, it is possible to swap
from the automatic control (rEG) to the OFF control (OFF) and vice
versa.
diSP -
VARIABLE VISUALISED ON THE DISPLAY SV:
Parameter
trough which it’s possible to decide what is visualised on the display
SV : the active Set Point (= SP.F), the Set Point active when there
are ramps (= SP.o), the control power (= Pou), the alarm thresholds
AL1, 2 or 3 (= AL1, AL2 or AL3) or it can be switched off (OFF).
Edit
- FAST PROGRAMMING OF ACTIVE SET POINT AND
ALARMS: This decides which are the Sets that can be programmed
by the fast procedure. The parameter can be programmed as :
=SE: The active Set Point can be modified while the alarm
thresholds cannot be modified
=AE :The active Set Point cannot be modified while the alarm
thresholds can be modified
=SAE: If the active Set Point or the alarm thresholds can be
modified
=SAnE: If the active Set Point or the alarm thresholds cannot be
modified

(PARAMETERS RELATIVE TO THE SERIAL
COMMUNICATION):
If the instrument is equipped with RS485
serial communication these parameters allow device
configuration for communication.
Add
– STATION ADDRESS IN CASE OF SERIAL
COMMUNICATION : This is used to set the instrument address in
the communication net. Programme a different number for each
station, from 1 to 255.
baud
– TRANSMISSION SPEED (BAUD RATE): Set the data
transmission speed of the network to which the instrument is
connected. The possible selections are 1200, 2400, 9600, 19.2
(19200), 38.4 (38400).
All stations must have the same transmission speed.
PACS
ACCESS TO PROGRAMMING THROUGH SERIAL PORT :
Programming access. If programmed as "LoCL" this means that the
instrument can only be programmed from the keyboard, if
programmed as "LorE" it can be programmed from both the
keyboards and serial line.
6 - PROBLEMS, MAINTENANCE AND GUARANTEE
6.1 - ERROR SIGNALLING
In error conditions, the instrument provides an output power as
programmed on par “OPE” and activates the desired alarms, if the
relative parameters “ALni” have been programmed = yES.
6.2 - CLEANING
We recommend cleaning of the instrument with a slightly wet cloth
using water and not abrasive cleaners or solvents which may
damage the instrument.
6.3 - GUARANTEE AND REPAIRS
The instrument is under warranty against manufacturing flaws or
faulty material, that are found within 12 months from delivery date.
The guarantee is limited to repairs or to the replacement of the
instrument.
The eventual opening of the housing, the violation of the instrument
or the improper use and installation of the product will bring about
the immediate withdrawal of the warranty’s effects.
In the event of a faulty instrument, either within the period of
warranty, or further to its expiry, please contact our sales
department to obtain authorisation for sending the instrument to our
company.
The faulty product must be shipped to TECNOLOGIC with a detailed
description of the faults found, without any fees or charge for
Tecnologic, except in the event of alternative agreements.

- - - -
Probe interrupted
uuuu
The measured variable
is under the probe’s
limits (under-range)
oooo
The measured variable
is over the probe’s
limits (over-range)
Verify the correct
connection between
probe and
instrument and then
verify the correct
functioning of the
probe
ErAt
Auto-tuning not possible
because the process
value is higher (with
“Func” =HEAt) than [SP-
|SP/2|] or lower (with
“Func” =CooL) than
[SP+ |SP/2|]
Swap the instrument
to OFF control (OFF)
and then to
automatic control
(rEG) in order to
make the error
message disappear.
Once the error has
been found, try to
repeat the auto-
tuning.
noAt
Auto-tuning not finished
within 12 hours
Check the
functioning of probe
and actuator and try
to repeat the auto-
tuning.
LbA
Loop control interrupted
(Loop break alarm)
Check the working of
probe and actuator
and swap the
instrument to (rEG)
control
ErEP
Possible anomaly of the
EEPROM memory
