3 ELECTRICAL HOOKUP

We recommend you:

▶

To avoid crossing cables by separating very low connections

from load-referred connections.

▶

While establishing connections to evaporative cooling mod-

ule follow carefully the specic instructions and information

provided by manufacturer.

We remind you that the instrument is not protected from

electrical overloading:

▶

Beware to equip outputs with necessary security devices;

▶

Make sure that employment conditions like supply tension,

environment temperature and humidity are within the indi-

cated limits.

For the connection, follow the diagram in Figure 19.1

6 COMMAND DESCRIPTION

Table6.1

Button Action / Result

During the parameter programming phase it increases the value on the display.

Pressed for more than 2 seconds together with DW command, adjusts the screen contrast.

Pressed once with the unit switched OFF (the display shows “oFF”) selects the operating mode: ventilation or cooling only.

During the parameter programming phase it decreases the value on the display.

Pressed for more than 2 seconds together with UP command, adjusts the screen contrast.

Pressed once with the unit switched OFF (the display shows “oFF”) selects the operating mode: ventilation or cooling only.

I/O

Pressed during programming, works like enter key.

Pressed for more than 1 second, switches the cooling unit on or o.

Pressed for more than 2 seconds together with FAN command, changes the default parameters.

Pressed for more than 3 seconds with the keypad locked it allows the keypad to be released temporarily.

FAN

During the parameter programming phase it acts as an exit button.

Pressed briey it shows the fan speed set and allows access to the fan speed modication phase.

Pressed for more than 2 seconds together with I/O command, changes the default parameters.

Table6.2

Icons

Cooling: when the led is on and the label COOL is shown, the unit is working in cooling mode.

Programming: the led keeps on during programming.

Ventilation: icon lit together with the word FAn, the unit is activated in ventilation mode. The 3-notch bar indicates the speed at

which ventilation is active: only one notch F1 / two notches F2 / three notches F3.

7 LOCKING/UNLOCKING THE REMOTE CONTROL UNIT

To lock the remote command unit, the HL parameter value must

be set as YES (see Paragraph 12

p.6

and 13

p.6

With the remote command unit locked, the following operations

are not allowed:

▶

setting the default parameters

▶

setting the remote command unit operating mode

▶

displaying the fan speed

When the remote control is locked, display shows “loc”

when pressing any key.

To temporarily release the keyboard, keep the

key pressed

until the word "Loc" changes to "OFF". The keypad automatically

returns to the lock condition after 15 sec. from the last press of

a button.

▶

Press the

key, the display now shows the fan speed.

▶

To exit press

or wait 8 sec. without pressing any key.

To change the fan speed:

▶

Press the

key, the display now shows the current fan

speed.

▶

Press

to increase the fan speed.

▶

Press

to decrease fan speed.

To exit the procedure and record the changes press the

key

or wait 8 sec. without operating on the keyboard.

11 PASSWORD PROTECTION PARAMETERS

It is possible to lock the remote control unit to avoid unauthor-

ised tampering. When you enter the parameters lists "user" / "in-

staller" / "factory", the display shows "PA" and a password may

be required.

1. Press the key

to enter the password value.

2. Type the right password using key

and

, press once

the key

again.

3. If the operation has been correctly performed, the rst pa-

rameter of the parameter list will be displayed, otherwise it

will be possible to read and change only the parameters of

the "user" list.

In both cases, when scrolling through the list of parame-

ters the conguration icon " " remains lit.

To access only the "user" list, once the "PA" message ap-

pears, press the

key twice without paying attention

to the value of the PA parameter.

12 SETTING PARAMETERS

The device has 3 parameter lists: “User”, “Installer” and “Factory”.

To enter/modify the “User” parameter list, it is not necessary to

insert the right password, instead the correct password is re-

quired to enter/modify the “Installer” / “Factory” parameters.

To enter the parameters list proceed as follows:

1. Press the

and

keys for at least 2 seconds.

2. The display shows “PA”.

3. To set the “installer” or “manufacturer” list enter the correct

PAssword (see Paragraphs 11

p.6

e 14

p.6

4. To view/modify only the "user" type parameters, press the

key twice.

5. Press

to locate the parameter to alter/set.

6. Press the

key to display the parameter value.

7. Press the

button to change the value.

8. Press the

button again to go back to the parameter list.

To save changes and exit the parameter setting, press

wait 30 sec.

17 COMMAND TYPE SELECTION: MASTER/SLAVE

Make sure the evaporative cooler is switched o and

without power supply before performing this operation.

In case of more power modules connected in parallel, just one of

them will be the master of the network, while the others will be

the slave modules.

In order to change a power module into a slave module, make a

bridge between V- and M/S (Figure 19.1

p.8

18 ALARMS

Alarms EA are related to the variation of the oat 1 status.

Parameter Y8 sets the delay in signalling the alarm of full tank;

should oat 1, full tank oat, not change its status within a time

Y8, it means that there is a problem with the tank ll and the

controller signal an alarm.

To exclude the alarm set Y8=0.

Parameter Y9 sets the delay in signalling the alarm of empty

tank; should oat 1, full tank oat, not change its status within

a time Y9, it means that there is a problem with the tank ll and

the controller signal an alarm.

To exclude the alarm set Y9=0.
