d2d
Digital inputs 2 alarm delay:
(0 to 255) it is the delay between the detection of an external
event and the activation of the relative function.

(0 to 15) after
reaching
nPS
events in the digital input alarm delay (par.
dxd
) the regulation will be stopped
and a manual restart (ON/OFF, power OFF and power ON) will be required

(no; FAn; CPr; F-C):
no
= normal;
FAn
= Fans OFF;
CPr
= Compressor OFF;
F-C
= Compressor and fans OFF.
rrd
Regulation restart after door open alarm:
(n; Y)
n
= no regulation if door is opened;

(0 to 255)
ENERGY SAVING
ErA
Energy reduction algorithm used:

nu
=no energy saving algorithm used;
bAS
=basic energy saving algorithm;
Aut
=automatic energy saving algorithm.
nbo
Threshold for mode change (normal mode to energy saving mode):
(0 to 10)
HES
Differential for energy saving mode:
(-30.0 to 30.0°C; -54 to 54°F) it sets the increasing
value of the set point during the Energy Saving cycle.
LdE
Energy saving mode controls the lights (lights off when energy saving goes active):
(n;

ErA
.

DIGITAL INPUT
The free voltage digital input is programmable in different configurations by the
i1F
and
i2F
.
DOOR SWITCH (ixF=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
did
, the door alarm is enabled,
the display shows the message
“
dA
”
and
the regulation restarts if rrd = 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.
START DEFROST (ixF=dEF)
It starts a defrost if there are the right conditions. After finishing any defrost, the normal regulation will
restart only if the digital input is disabled, otherwise the instrument will wait until the
MdF
safety time is
expired.
ENERGY SAVING (ixF=ES)
The energy saving mode will be enabled / disabled with the digital input.
MOTION SENSOR (ixF=MS)
The external motion sensor activation is counted.
AUXILIARY OUTPUT (ixF=AUS)
The AUX output (if present and configured) will be enabled / disabled with the digital input.
EXTERNAL WARNING ALARM (ixF=EAL)
It is used to detect an external alarm. This signal does not lock the regulation.
EXTERNAL LOCK ALARM (ixF=bAL)
It is used to detect any critical external alarm. This signal locks immediately the regulation.
EXTERNAL PRESSURE ALARM (ixF=PAL)
It is used to detect any pressure external alarm. This signal locks the regulation after
nPS
events in
dxd
interval od time.
REMOTE HOLYDAY MODE (ixF=HdF)
It is used to force the holyday mode.
REMOTE ONOFF (ixF=onF)
It is used to switch ON and OFF the device remotely.

INSTALLATION AND MOUNTING
Instrument
XRB60CHC
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 -20 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.
13
OPTIONAL FEATURES
The
MDP/CX
rear cover can be used to increase the protection
from water and dust.
The
HOT-KEY
is used for a quick and easy upload (from device
to
HOT-KEY
) or download (from
HOT-KEY
to device) of the
parameter map.
The BLU serial interface converts the TTL output into an RS485
signal that can be used to connect the unit to the controlling and
supervising system. Please note that standard version of this
converter does not work with XR-CHC devices.
14
ELECTRICAL CONNECTIONS
The instrument is provided with screw terminal block to connect cables with a cross section up to
2.5mm
2
. Before connecting cables make sure the power supply complies with the inst
rument’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.
14.1
PROBES
The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid
infiltration. It is recommended to place the thermostat probe away from air streams to correctly
measure the average room temperature. Place the defrost termination probe among the evaporator
fins in the coldest place, where most ice is formed, far from heaters or from the warmest place during
defrost, to prevent premature defrost termination.
