the right hand side, are used to action the

associated options :

In the menu tree the up/down arrow keys are

used to navigate through the menu’s one option

at a time (NB pressing the down arrow in the

example above will take you to the “Status” line

& the up arrow to the “Setup” line. Pressing F1

or F3 will move up or down three lines at a time

[page up or page down]. F2 will take you to the

“Logon” screen. Pressing the “Escape” key at

any time will move you bake one level in the

menu, repeated presses will take you back to

the default screen shown in Fig. 1.

Fig 1A shows the “unit status” menu tree screen.

From here it is possible to view the status of the

unit parameters.

If you report a fault to Vapac Humidity Control

Ltd, you may be asked to provide this

information to enable the problem to be

diagnosed.

Ltd. It is password protected and used to set the number of electrodes and

number of times the electrode cable passes through the toroid

1-4 Setup unit This option is used to set the site controlled parameters:

Control type: (0-5V; 0-10V; 2-10V; 1-18V; 0-20V; 4-20mA; Pot; Full output;

Network; or Sensing Head [0-5V; 0-10V; 0-20V; 4-20mA or pot].

1-5 Network Setup Used to set-up master/slave systems: Password protected (Password

1111). Select this option (from the master unit), confirm by pressing “ok”

then press the service pin (this is referred to as the network button in the

operating manual) on the motherboard that is fitted to the first slave unit

(please ensure that this is the next largest unit). What while the slave unit is

“configured” then press “ok” to finish the network set-up or proceed to the

next slave unit and press its service pin. Once all the units are configured

press “ok” to confirm that the set-up is complete.
