LIST OF PARAMETERS
REGULATION
Hy1 Intervention differential for set point1 (-Full Sc. / Full

this value is subtracted from the set point1. The alarm
signal is enabled when the temperature goes below the
“SET1-ALL” value.

minimum alarm is enabled when the temperature goes
below the “ALL” value.
ALU Maximum alarm:
with ALC=rE: alarm relative to set point1, (0÷|Full Sc.-
Set1|) Maximum alarm is enabled when the temperature
exceeds the “SET1+ALU” value.

alarm is enabled when the temperature exceeds the
“ALU” value.

INSTALLATION AND MOUNTING
Instrument XT220C and XT221C shall be mounted on vertical
panel, in a 29x71 mm hole, and fixed using the special
brackets supplied.
To obtain an IP65 protection grade use the front panel rubber
gasket (mod. RG-C).
The temperature range allowed for correct operation is 0
÷
60
°C. Avoid places subject to strong vibrations, corrosive gases,
excessive dirt or humidity. The same recommendations apply
to probes. Let air circulate by the cooling holes.
9.
ELECTRICAL CONNECTIONS
The instruments are provided with screw terminal block to
connect cables with a cross section up to 2,5 mm
2
. Before
connecting cables make sure the power supply complies with
the instrument’s requirements. Separate the input connection
cables from the power supply cables, from the outputs and the
power connections. Do not exceed the maximum current
allowed on each relay, in case of heavier loads use a suitable
external relay.
10.
SERIAL CONNECTIONS
All models can be connected to the monitoring and supervising
system XJ500 using the serial port. The external XJ485 serial
module to interface the instrument with the monitoring and
supervising system XJ500 is required.
The standard ModBus RTU protocol it is used.
NOTE: Instruments with current or voltage input and 230V
or 115V supply, cannot be connected to the XJ485 serial
module.
