DIXELL XT111C FOR PRO/XLT MODELS
GENERAL WARNING
Please read before using this
manual
• This manual is part of the product and
should be kept near the instrument for
easy and quick reference.
• The instrument shall not be used for
purposes different from those de
scribed hereunder. It cannot be used
as a safety device.
• Check the application limits before
proceeding.
Safety Precautions
• Check the supply voltage is correct
before connecting the instrument.
• Do not expose to water or moisture:
use the controller only within the
operating limits avoiding sudden
temperature changes with high at-
mospheric humidity to prevent forma-
tion of condensation
• Warning: disconnect all electrical con-
nections before any kind of mainte-
nance
• The instrument must not be opened.
• In case of failure or faulty operation
send the instrument back to the dis-
tributor with a detailed description of
the fault.
• Consider the maximum current which
can be applied to each relay (see
Technical Data).
• Ensure that the wires for probes, loads
and the power supply are separated
and far enough from each other,
without crossing or intertwining.
• In case of applications in industrial
environments, the use of mains filters
(our mod. FT1) in parallel with
inductive loads could be useful.
GENERAL DESCRIPTION
The XT110C and XT111C are single-stage
ON/OFF controllers for temperature,
humidity and pressure applications with
direct or inverse action, user-selectable.
The analogue input type can be set by
parameter between the following,
according to the model:
- PTC, NTC;
- PTC, NTC, Pt100, Thermocouple J, K, S;
- 4÷20mA, 0÷1V, 0÷10V.
FIRST INSTALLATION
Probe setting
The pre-set probe
type is written on the
label of the
instrument, see
picture. If it is
different from theprobe that has be used,
set the probe following procedure below
How to set the probe.
1. Enter the programming menu by
pressing the SET+ n for 3s.
2. Select the Pbc (Probe configuration)
parameter and push the SET key.
3. Set the kind of probe:
a. Controller for temperature: Pt=
Pt100, J = J thermocouple, c = K
thermocouple,
S = S thermocouple;
Ptc = PTC; ntc = ntc
b. Controller with current or
voltage inputs: cur=4÷20mA, 0-
1= 0÷1V, 10= 0÷10V
4. Push the SET key to confirm it.
5. Switch the controller
off and on again
NOTE: Before proceeding check and, if
necessary; set with appropriate values the
Minimum Set Points (LS1 e LS2) and
Maximum Set Points (US1 e US2). See
also the paragraphs concerning the
programming.
