How to use the HOT KEY
How to program a hot key from the
instrument (UPLOAD)
1. Program one controller with the front
keypad.
2. When the controller is ON, insert the
"Hot key" and push o key; the "uPL"
message appears followed a by
flashing "End"
3. Push "SET" key and the End will stop
flashing.
4. Turn OFF the instrument remove the
"Hot Key", then turn it ON again.
NOTE: the "Err" message is displayed for
failed programming. In this case push
again o key if you want to restart the
upload again or remove the "Hot key"
to abort the operation.
HOW TO PROGRAM AN INSTRUMENT USING A
HOT KEY (DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a programmed "Hot Key" into the
5 PIN receptacle and then turn the Con-
troller ON.
3. Automatically the parameter list of the
"Hot Key" is downloaded into the
Controller memory, the "doL" message
is blinking followed a by flashing "End".
4. After 10 seconds the instrument will restart
working with the new parameters.
5. Remove the "Hot Key"..
NOTE: the message "Err" is displayed for
failed programming. In this case turn the
unit off and then on if you want to restart
the download again or remove the "Hot
key" to abort the operation.
digital input
XT110C and XT111C have 1 free contact
digital input. It is programmable in 5
different configurations by the "i1F"
parameter.
invert the kind of action: heatingcooling
(I1F = C-H)
This function allows to invert the regulation
of the controller: from direct to inverse and
viceversa.
REMOTE ON/OFF (I1F = OFF)
This function allows to switch ON and OFF
the instrument.
User Instructions Ultra Low Temperature Freezers Model LAB/ULT
GENERIC ALARM (i1F = EaL)
As soon as the digital input is activated the
unit will wait for "did" time delay before
signalling the "EAL" alarm message. The
outputs status don't change. The alarm
stops just after the digital input is deacti-
vated.
serious alarm mode (I1F = BAL)
When the digital input is activated, the unit
will wait for "did" delay before signalling the
"bAL" alarm message. The relay outputs are
switched OFF. The alarm will stop as soon as
the digital input is de-activated.
energy saving (I1F = HES)
The Energy Saving function allows to change
the set point1 value as the result of the SET1
+ HES (parameter) sum. This function is en-
abled until the digital input is activated.
