6) Installation

To install your Advisor, follow the installation procedure as
outlined below.

a)  Insert the instrument into the panel opening from the

front.

b)  Fix the two panel mounting clips to opposite sides of

the instrument and tighten until the instrument is
secure.

c)  Connect the panel wiring to the rear terminal blocks.

7) Electrical Connections

All connections to the instrument are made using high
quality two part PCB connectors with screw clamp terminals
(which accept cables between 0.5 and 1.5mm

2

 in diameter).

This makes installation and removal much easier.

Power Supply Connections

Signal Input and Optional Alarm Connections

NOTE: Alarm terminals may carry up to

240Vac

Optional Output Connections

8) Setting Up

8.1 General

The Advisor panel meters are set up using the four front panel
pushbuttons. Parameters are accessed using a menu which may
be protected by a user programmable password.

It is possible to disable the pushbuttons to stop any tampering by
unauthorized personnel. If the anti-tamper pushbutton disable
function has been switched on, you will need to regain “local”
control by following the key press sequence as outlined in section
8.7

8.2 Button Functions – In Programming Mode

To enter programming mode, press the scroll and return buttons
together.

When the instrument is supplied, the security access password is
set to “0000”. If this password hasn’t been changed, then the
operator is given immediate access to the programming mode. If
the password has been changed, then the operator will need to
enter the new password before being able to access programming
mode.

In Programming Mode, the pushbuttons have the following
functions;

Decreases a setting/variable or moves to the previous
menu option. This button is referred to as the “down

button”

Increases a setting/variable or moves to the next menu
option. This button is referred to as the “up button”

Select a menu option or “scroll into” next menu option.
This button is referred to as the “scroll button”.

Confirm variable selection or return to previous menu
option or exit programming mode. This button is referred

to as the “return button”.

8.3) General Programming Structure

The above flow chart gives a general overview of the
programming structure for an Advisor. The key point to remember
is that if you ever get lost or unsure of what function you are
programming, keep pressing the return button and eventually you
will get back to the normal display mode.
