Push and immediately release the
SET
key: the display will show the
Set point value;
6.2
HOW TO CHANGE THE SETPOINT
1.
Push the
SET
key for more than 2 seconds to change the Set
point value;
2.
The value of the set point will be displayed and the
LED starts
blinking;
3.
To change the Set value push the
o
or
n
arrows.
4.
To memorise the new set point value push the
SET
key again or
wait 15s.
6.3
HOW TO START A MANUAL AGITATION CYCLE
6.4
HOW TO CHANGE A PARAMETER VALUE
To change the parameter’s value operate as follows:
1.
Enter the Programming mode by pressing the Set and UP key for
3s (
and
start blinking).
2.
Select the required parameter.
3.
Press the “
SET
” key to display its value (
LED starts blinking).
4.
Use “
UP
” or “
DOWN
” to change its value.
5.
Press “
SET
” to store the new value and move to the following
parameter.
To exit
: Press
SET + UP
or wait 15s without pressing a key.
NOTE
: the set value is stored even when the procedure is exited by waiting the time-out to
expire.
6.5
THE HIDDEN MENU
The hidden menu Includes all the parameters of the instrument.
6.5.1 HOW TO ENTER THE HIDDEN MENU
1.
Enter the Programming mode by pressing the Set +
n
key for 3s
(
and
start blinking).
2.
When a parameter is displayed keep pressed the Set+
n
for more
than 7s. The Pr2 label will be displayed immediately followed from the
HY parameter.
NOW YOU ARE IN THE HIDDEN MENU.
3.
Select the required parameter.
4.
Press the “
SET
” key to display its value (Now only the
LED is
blinking).
5.
Use
o
or
n
to change its value.
6.
Press “
SET
” to store the new value and move to the following parameter.
To exit
: Press
SET +
o
or wait 15s without pressing a key.
NOTE
: the set value is stored even when the procedure is exited by waiting the time-out to
expire.
6.5.2 HOW TO MOVE A PARAMETER FROM THE HIDDEN MENU TO
THE FIRST LEVEL AND VICEVERSA.
Each parameter present in the HIDDEN MENU can be removed or put into “THE FIRST
LEVEL” (user level) by pressing
“SET +
n
”
.
In HIDDEN MENU when a parameter is present in Fisrt Level the decimal point is on.
6.6
HOW TO LOCK THE KEYBOARD
1.
Keep pressed for more than 3 s the UP and DOWN keys.
2.
The “POF” message will be displayed and the keyboard will be locked. At this point it
will be possible only to see the set point or the MAX o Min temperature stored
3.
If a key is pressed more than 3s the “POF” message will be displayed.
6.7
TO UNLOCK THE KEYBOARD
Keep pressed together for more than 3s the UP and DOWN keys.
7.
LIST OF PARAMETERS
NOTE: the parameters preceded by dots usually are only in the Hidden Menu.
REGULATION
Hy Differential
: (0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for set point.
Compressor Cut IN is Set Point Plus Differential (Hy). Compressor Cut OUT is when
the temperature reaches the set point.
•
LS Minimum set point
: (- 50°C÷SET / -58°F÷SET): Sets the minimum acceptable
value for the set point.
•
US Maximum set point
: (SET÷ 150°C / SET÷302°F). Set the maximum acceptable
value for set point.
Ot Thermostat probe calibration
: (-12.0÷12.0°C;
-120÷120°F) allows the adjustment of possible offset of the thermostat probe.
•
OdS Outputs
activation
delay at start up:
(0÷255min) This function is enabled at
the initial start up of the instrument and inhibits any output activation for the period of
time set in the parameter.
AC Anti-short cycle delay
: (0÷50 min) minimum interval between the compressor stop
and the following restart.
•
COn Compressor ON time with faulty probe
: (0÷255 min) time during which the
compressor is active in case of faulty thermostat probe. With COn=0 compressor is
always OFF.
•
COF Compressor OFF time with faulty probe
: (0÷255 min) time during which the
compressor is OFF in case of faulty thermostat probe. With COF=0
compressor is
always active.
DISPLAY
•
CF
Temperature measurement unit
: °C = Celsius; °F= Fahrenheit.
WARNING
:
When the measurement unit is changed the SET point and the values of the
parameters Hy, LS, US, Ot, ALU and ALL have to be checked and modified if
necessary).
rES Resolution (for °C)
: (in = 1°C; dE = 0.1 °C) allows the decimal point displaying.
AGITATION CYCLE
•
AgC Agitator configuration EL
= switched
ON and OFF with the compressor;
in
= switched
ON according to parameter IAg.
•
tiC Resolution for the Agt parameter
nP
= the Agt parameter is in minutes
Pb
= the Agt parameter is in seconds
iAG Interval between agitation cycles
: (1
÷
120 min) Determines the time interval
between the beginning of two agitation cycles.
NOTE:
When a continuous agitation
cycle is started, the time counting is reset and starts from zero.
Agt Length for agitation cycle
: (0
÷
255 min/sec) It sets the agitation cycle duration.
APO First agitation cycle after start-up
: (y = Immediately; n= after the IAG time)
ALARMS
•
ALC Temperature alarms configuration
: (Ab; rE)
Ab
= absolute temperature: alarm temperature is given by the ALL or ALU values.
rE
= temperature alarms are referred to the set point. Temperature alarm is enabled
when the temperature exceeds the “SET+ALU” or “SET-ALL” values.
ALU MAXIMUM temperature alarm
: (ALL÷150°C;
ALL ÷302°F) when this temperature is reached the alarm is enabled, after the “ALd”
delay time.
ALL Minimum temperature alarm
: (-50.0°C ÷ ALU;
-58°F ÷ ALU) when this temperature is reached the alarm is enabled, after the “ALd”
delay time.
•
ALd Temperature alarm delay
: (0÷255 min) time interval between the detection of
an alarm condition and alarm signalling.
•
dAO Exclusion of temperature alarm at startup
: (from 0.0 min to 23.5h) time
interval between the detection of the temperature alarm condition after instrument
power on and alarm signalling.
OTHER
•
PbC Probe selection:
(Ptc=PTC probe; ntc=NTC probe). It allows the selection of
the type of probe.
•
rEL Software release
for internal use.
•
Ptb Parameter table code:
readable only.
