DESCRIPTION OF PCD REMOTE CONTROL PANEL

The PCD remote control panel allows you to rapidly set the machine operating

parameters, display them at any time and obtain an immediate picture of the machine

operating status.

The display contains 3 digits and 5 LEDs for indicating the operating mode, displaying

the parameters set or measured and signalling any alarms that have been triggered.

The PCD remote control terminal is supplied in two different versions, depending on

the chilling unit it will be combined with:

- Install the serial converter (figure 1b) in the guide track situated near the

terminal block of the electric control board (figure 1a);

- Using the wire provided, connect the serial converter to the electronic

regulator already installed on the electric control board of the unit;

- Then connect wires 0V and 24V, situated on the control board, respectively

with serial converter terminals 11 and 12 (figure 1a);

- Connect the serial converter and remote terminal following the directions shown

on the machine wiring diagram or using the numbers of the terminals of the two

components as your reference; use a shielded cable with three twisted pairs

(maximum length 150 m) to make this connection and connect the cable shield to

earth.

- After making all the electrical connections, check the position of the four

microswitches on the electronic card inside the remote terminal; microswitches

1 and 2 should be in the OFF position, while numbers 3 and 4 should be ON.

When the power supply to the machine is turned on, the letters "CN" will appear on

the display (error in communication with remote terminal) since the regulator is still

set for only one terminal. To enable the second terminal you must change the parameter

H8 either from the remote terminal or using the electronic controls on the machine;

carry out the following steps:

1) Keep the "SEL" and "PRG" keys pressed down together for at least 5 seconds

until the flashing digits 00 appear on the display (figure 2);

2) Using the "UP" and "DOWN" keys set the number on the display to 177, which

is the password for changing parameters. Then press the "SEL" key to confirm

the selection and access the programming mode;

Note: once the procedure has been activated, if no key is pressed during the next

60 seconds the control will go back to the normal operating mode without storing

any parameters that may have been changed.

3) Once you have accessed the programming mode, you can view the codes of all

the parameters by pressing the "UP" and "DOWN" keys;

4) Run through the parameters until you reach H8 (the parameter that establishes

the number of terminals) and press "SEL" to display the setting;

5) Change the default setting from 0 to 1 to enable the second terminal. Then press

"PRG" to memorise the new setting.

WARNING

: do not change the settings of the other parameters; any changes

may cause the unit and its safety devices to cease working efficiently.

Remote contacts

The electronic regulator is equipped with remotely controlled contacts that allow you

to turn the unit on and off or switch between summer and winter.

These contacts can be disabled so that the ON/OFF and summer-winter changeover

functions may be activated solely from the electronic controls and remote terminal.

Conversely, enabling the contacts will partly limit the possibility of activating the ON/

OFF and summer-winter changeover functions with the electronic controls and remote

terminal, as is explained below.

The remote contacts can be enabled and disabled by changing some parameters of

the electronic regulator. The steps to follow are the same as those described previously

for changing the parameter H8.

Enabling the remote ON/OFF contact:

If H7 = 1 (default setting) the remote ON / OFF contact will be enabled; if the contacts

of the remote ON/OFF are open the machine will remain off and disabled; if they are

closed, the machine will be enabled and may be turned on or off using either the

electronic regulator on the machine itself or the remote terminal.

Disabling the remote ON/OFF contact:

If the parameter H7 is instead set on 0, the remote ON / OFF contact will be disabled;

in this case the machine can be turned on or off as desired using either the electronic

regulator on the machine itself or the remote terminal.

Enabling the remote "summer-winter changeover" contact:

For chilling units with heat pumps, you can enable or disable the remote summer/

winter contact by changing the parameter P8.

If P8 = 3 (default setting) the summer-winter contact is enabled: the machine will work

only as a chilling unit if the summer-winter contact is open; conversely, if the summer-

winter contact is closed, the machine will work only as a heat pump.

Therefore in this case (P8=3) the operating mode can only be changed by means of

the summer-winter contact; the summer-winter changeover function of the electronic

regulator on the machine and the remote terminal will be disabled.

- Install the remote control card on the four spacers provided near the main

card of the electric control board (see layout of electric control board);

- Disconnect the wire attached to the electronic regulator from the main card;

- Using the wire provided with the remote control card, connect the main card to

the remote control card;

- Connect the wire attached to the electronic regulator (previously disconnected

from the main card) to the remote control card;

- Connect the remote control card and the remote terminal, using the numbers of

the terminals of the two components as your reference; use a shielded cable

with three twisted pairs (maximum length 150 m) to make this connection and

connect the cable shield to earth.

- After making all the electrical connections, check the position of the four

microswitches on the electronic card inside the remote terminal; microswitches

2 and 3 should be in the OFF position, while numbers 1 and 4 should be ON.

disabled; in this case the machine can be turned on or off as desired using either

the electronic regulator on the machine itself or the remote terminal.

Enabling the remote "summer-winter changeover" contact:

For chilling units with heat pumps, you can enable or disable the remote summer-

winter contact by changing the parameter H6.

If H6 = 1 (default setting) the summer-winter contact is enabled: the machine will

work only as a chilling unit if the summer-winter contact is open; conversely, if the

summer-winter contact is closed, the machine will work only as a heat pump.

Therefore in this case (H6=1) the operating mode can only be changed by means

of the summer-winter contact; the summer-winter changeover function of the

electronic regulator on the machine and the remote terminal will be disabled.

Disabling the remote "summer-winter changeover" contact:

If H6 = 0 the summer-winter contact is disabled; the machine can be switched to

the desired operating mode using either the electronic regulator on the machine or

the remote terminal.
