DIGITAL INPUTS
The first digital input (terminals 18-20) is enabled with
P3P=n
.
The free voltage digital inputs are programmable by the
i1F
parameter.
13.1
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 does
n’t
change. The alarm stops just after the digital input is de-
activated.
13.2
SERIOUS ALARM MODE (i1F = bAL)
When the digital input is activated, the unit will wait for
did
delay before signalling the “
CA
” alarm
message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-
activated.
13.3
EXTERNAL PRESSURE ALARM (i1F =PAL)
It is used to detect any pressure external alarm. This signal locks the regulation after detecting
nPS
events in the interval
dxd
.
13.4
DOOR SWITCH INPUT (i1F = dor)
It signals the door status and the corresponding relay output status through the
odC
parameter:
no
= normal (any change);
FAn
= Fan OFF;
CPr
= Compressor OFF;
F_C
= Compressor and fan OFF.
Since the door is opened, after the delay time set through parameter
doA
, the door alarm is enabled,
the display shows the message
dA
and the regulation restarts is
rtr=Y
. The alarm stops as soon as
the external digital input is disabled again. With the door open, the high and low temperature alarms
are disabled.
13.5
START DEFROST (i1F = dEF)
It starts a defrost if there are the right conditions. After the defrost is finished, the normal regulation will
restart only if the digital input is disabled otherwise the instrument will wait until the
MdF
safety time is
expired.
13.6
SWITCH THE AUXILIARY RELAY (i1F = AUS)
With
oAx=AUS
the digital input switched the status of the auxiliary relay.
13.7
INVERSION OF THE KIND OF ACTION: HEATING-COOLING (i1F = Htr)
This function allows inverting the regulation of the controller: from cooling to heating and viceversa.
13.8
ENERGY SAVING (i1F = ES)
The Energy Saving function allows to change the set point value as the result of the
[SET+HES]
(parameter) sum. This function is enabled until the digital input is activated.
13.9
ON OFF FUNCTION (i1F = onF)
To switch the controller on and off.
13.10
CHANGE PARAMETER MAP (i1F = Lnt)
To move from LT to NT parameter map.
13.11
DIGITAL INPUTS POLARITY
The digital input polarity depends on the
i1P
parameter.
•
i1P=CL
, the input is activated by closing the contact.
•
i1P=OP
, the input is activated by opening the contact.
14.
SERVICE SERIAL PORT
A specific serial tool (XJ485CX) can be connected to the HOTKEY port to change parameter
configuration. To do this, set par
1Ao=n
: the frequency output must be disabled to use the service
serial port.
15.
INSTALLATION AND MOUNTING
Instrument
XRi60CH
shall be mounted on vertical panel, in a 29x71 mm hole, and fixed using the
special bracket supplied. The temperature range allowed for correct operation is 0 to 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.
16.
ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross section up to
2.5mm2. Before connecting cables make sure the power supply complies with the instrument’s
requirements. Separate the probe 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.
