Emerson Dixell XR10C User Manual

1592007201 XR10C-D GB r1.0 18.11.2015 XR10C – XR10D 3/4
8.6 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
9. INSTALLATION AND MOUNTING
Instrument XR10C shall be mounted on vertical panel,
in a 29x71 mm hole, and fixed using the special
bracket supplied.
To obtain an IP65 protection grade use the front
panel rubber gasket (mod. RG-C) as shown in
figure.
Instrument XR10D shall be mounted on an omega DIN rail
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.
10. ELECTRICAL CONNECTIONS
The instrument is 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 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.
10.1 PROBE CONNECTION
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.
11. HOW TO USE THE HOT KEY
11.1 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.
11.2 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 Controller 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.
12. ALARM SIGNALS
Message
Cause
Outputs
“P1”
Room probe failure
Compressor output according
to par. “Con” and “COF”
“HA”
Maximum temperature alarm
Outputs unchanged.
“LA”
Minimum temperature alarm
Outputs unchanged.
“dA”
Door open
Regulation restarts
“EA”
External alarm
Output unchanged.
“CA”
Serious external alarm (i1F=bAL)
All outputs OFF.
“CA”
Pressure switch alarm (i1F=PAL)
All outputs OFF
12.1 ALARM RECOVERY
Probe alarm “P1” starts some seconds after the fault in the related probe; it
automatically stops some seconds after the probe restarts normal operation.
Check connections before replacing the probe.
Temperature alarms “HA” and “LA” automatically stop as soon as the thermostat
temperature returns to normal values and when defrost starts.
Alarms “EA” and “CA” (with i1F=bAL) recover as soon as the digital input is
disabled.
Alarm “CA” (with i1F=PAL) recovers only by switching off and on the instrument.
