4.2 Advanced internal parameter
programming
The parameters are programmed via a serial link by expert and trained
personnel. This procedure for setting the parameters allows more speci c
functions to be selected than those available with manual setting.
Function Variable State Description
Enable output override
WE
CO.1
0 : Disable override of variable EOVR
1 : Enable override of variable EOVR
Reset default values
FDEF
CO.7
0 : No action
1 : Reset default values (one time)
Save parameters
SAVE
CO.8
0 : No action
1 : Save the values to memory (one time)
Override input variable
IOVR
CO.9
0 : No action
1 : Enable override of input variable and use INMEM
Logic of digital inputs SW1+SW2
MODID
CO.10
0 : Normally closed
1 : Normally open
Override output variable
EOVR (1)
CO.11
0 : No action

Maximum temperature alarm threshold setting
TEMPALM+
HO.5
-30 -105 High temperature alarm value (integer with sign)
Minimum temperature alarm threshold setting
TEMPALM-
HO.6
-30 -105 Low temperature alarm value (integer with sign)
Input delay setting
DELAYINMEM
HO.8
0-100
Response time to an input step. The range of adjustment from 0-100%
(clockwise) corresponds to setting the time from 0-10 sec
Output in the event of alarms or timeout
ALMO
HO.9
0/1/2
Select the output voltage in the event of alarm or serial line timeout and
activate input override (0=0% , 1=50%, 2 = 100%)
Controller output from memory
OUTMEM
HO.10
0-100 Output voltage value in the case of override (EOVR=1)
Serial communication timeout
TIMOEOUTH|L
HR.11| HR.12
0-5 |0-255
Serial communication timeout beyond which the link LED goes o and if
input override is enabled, the ALMO output is activated (seconds)
Saving timeout
TIMESAVE
HO.13
0-255
Time for saving the parameters. After this time, if changes are made to the
parameters, these are saved to memory (minutes)
