MODID Digital input mode
Modbus address read/write coil 10
resolution
and unit of measure
1
range 0/1
default 0
Parameter, to determine the digital input logic, used to activate the alarm
when the digital input status (STID) represents the reverse situation
• MODID=0 normally closed input logic
• MODID=1 normally open input logic
EOVR Override output
Modbus address read/write (*) coil 11
resolution
and unit of measure
1
range 0/1
default 0
Parameter to overwrite the output using a value set in the memory
(OUTMEM)
• EOVR=0 no override
• EOVR=1 enable override
(*) Possibility to activeted the override only if parameter WE=1
SEL Select controller settings
Modbus address read discrete input
1 – Reading of Dip
S2.1
resolution
and unit of measure
1
range 0/1
default R
Selects which parameters are used to manage operation of the controller.
Manual from FCR panel, Internal from FCR memory
• SEL=0 Select manual from FCR panel (MAN) –
Use the variables with su x FCR
• SEL=1 Select internal from FCR memory (MEM)
Use the variables with su x MEM
HZFCR Select frequency from manual
Modbus address read discrete input
2 – Reading of Dip
S2.4
resolution
and unit of measure
1
range 0/1
default R

LINFCR Select operating curve
Modbus address read discrete input
3 – Reading of Dip
S2.5
resolution
and unit of measure
1
range 0/1
default R
This parameter is used to select linear or quadratic control

ALRTMP Temperature alarm status
Modbus address read discrete input 7
resolution
and unit of measure
1
range 0/1
default R
Indicates activation of the temperature alarm based on the reading of the
sensor on the FCR and the set thresholds
• ALRTMP= 0 alarm deactivated red LED does not change
• ALRTMP= 1 alarm deactivated red LED  ashes
ALRPRC Probe short-circuited alarm
Modbus address read discrete input 8
resolution
and unit of measure
1
range 0/1
default R
This alarm indicates whether the temperature sensor is short-circuited.
