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.
