Read codes

Normally the selected temperature signal can be read from the

display, but under certain conditions the display may show other

codes in order to notify the user of various operating states.

Function

Display readout

OFF

When the "main switch" is set to OFF, the display will read "OFF"

PAS

Requirement for access code. If operation of the display is to be

protected by an access code, both the definition and the access

code must be set in the controllers' authorisation menu for the

local display (LOCD).

Alarm

The three LED's will flash if an alarm is triggered. The alarm code

can be viewed by pressing the top button. Pressing the button will

also reset the alarm relay

- - -

When three dashes appear, the valid temperature reading is faulty

(sensor switched off or short-circuited), or else the display has been

deactivated.

Configuration lock

You can only select a preset configuration or change refriger-

ant when the configuration lock is open.

0 = Configuration open

1 = Configuration locked

o62

Selection of predefined configuration.

This setting will give a choice from a series of predefined

combinations, which at the same time establish the connec-

tion points.

At the end of the manual there is an overview of the options

and connection points.

After configuration of this function, the controller will shut

down and restart.
