The 

05/ (Promote) option

Up to twelve commonly used parameters can be ‘promoted’ into
the  HOME list.  This will give the operator quick access to them

by simply pressing the 

  button.  This feature, used in

combination with ‘hide’ and ‘read only’, allows you to organise
the way in which you want your indicator formatted.

Select EDIT level to hide, reveal or promote parameters as below:

The parameter 

  ) will now appear in the HOME list.  Repeat

the procedure for any other parameters you wish to promote.
To de-promote a parameter go to 

O6 level, select the parameter

from the relevant list and change the choice from 

05/ back to

)65, 5 or #O.

Returning to Operator level
Repeat the above procedure for all the parameters you wish to hide,
promote, or make read-only then return to operator level:

Your indicator has been calibrated for life against known reference
sources in the factory.  User calibration allows you to apply offsets
to compensate for sensor and other system errors. You can apply a
simple fixed offset over the whole display range using the
parameter 

 in the O0 list, or alternatively, you may apply a 2-

point calibration as follows:

• 

Press 

 until you reach the 

O0 list

• 

Press 

 until you reach the 

)D0 parameter

• 

Press 

 or 

  to enter the password.  The factory default

password is 3.  

0 will be displayed when correct.

• 

Press 

 to reach the 

) parameter

• 

Press 

 or 

  to select 

85 (6 will restore the

factory calibration)

• 

Press 

 to select 

0.6D)

• 

Press 

 or 

 to adjust the value at which you wish to

apply the low calibration point offset. (eg zero)

• 

Press 

 to select 

D)

• 

Press 

 or 

 to set the low calibration point offset.

• 

Repeat the above to select and adjust 

0.6D# and D#

The graph below shows the effect of a low and high point offset.

These warn that a fault exists in either the indicator or the
connected devices.

EE.Er

Electrically Erasable
Memory Error:  The
value of an operator
or configuration
parameter has been
corrupted.

This fault will automatically
take you into configuration
level.  Check all of the
configuration parameters
before returning to operator
level.  Once in operator level,
check all of the operator
parameters before resuming
normal operation.  If the fault
persists or occurs frequently,
contact Eurotherm Controls.

Check that the sensor is
correctly connected.
