10. INSTALLATION AND MOUNTING
XC10CX and XC30CX shall be mounted on vertical panel, in a
29x71mm hole, and fixed using the special bracket supplied.
The temperature range allowed for correct operation is -10 to 55°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.
11. 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 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.
11.1 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.
12. HOW TO USE THE HOT KEY
12.1 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 UP button; the “uPL” message
appears followed a by a flashing “End” label.
3. Push SET button and the “End” will stop flashing.
4. Turn OFF the instrument, remove the “HOT-KEY” and then turn it ON again.
NOTE: the “Err” message appears in case of a failed programming operation. In this case push again
button if you want to restart the upload again or remove the “HOT-KEY” to abort the operation.
12.2 HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY (DOWNLOAD)
1. Turn OFF the instrument.
2. Insert a pre-programmed “HOT-KEY” into the 5-PIN receptacle and then turn the Controller
ON.
3. The parameter list of the “HOT-KEY” will be automatically downloaded into the Controller
memory. The “doL” message will blink followed a by a flashing “End” label.
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.
