CONFIGURATION LEVEL

The 2408

i

indicator is supplied configured in accordance with the ordering code (see section 5). The

configuration of the indicator, as defined by columns 11 to 16 of the order code, can be changed on site, if

necessary, to meet the requirements of the installation. Similarly, the positions or types of plug in module can be

changed if required. This section describes the procedures to be followed.

4.1

Hardware configuration - I/O Modules

Figure 4-1: View of the Plug-in Modules

Optional plug-in modules are fitted simply by sliding them into the

relevant position as shown in Figure 4-1. The connections for these

modules are made to the upper row of connector blocks as shown in

section 1.3.

When a module is added, removed or changed the indicator will flash

hardware error ‘<HWEr> on power up. To acknowledge this it is

necessary to go into configuration level.

1.

Press either

or

until <ConF> is displayed.

2.

Press

or

to enter the configuration level password

passcode (factory default 2)

3.

Press either

or

again and the hardware error is

acknowledged

The full list of modules available is shown in the ordering code.
