Output status indication: Two indicators (OUT 1
and OUT 2) are lits when the respective output is
in ON condition.
Output level limiter:
- For one control medium :
from 0 to 100 % .
- For two control mediums :
from -100 to +100 % .
This function may be operative at instrument start
up for a programmable time (To avoid thermal
shock and/or preheating the plant) otherwise it
can be enabled by an external contact.
Cycle times:
- For out 1 it is programmable from 1 to 200 s.
- For out 2 it is programmable from 1 to 200 s.
Relative cooling gain: programmable from
0.20 to 1.00.
Overlap/dead band: programmable from - 20 %
to + 50 % of the proportional band
OUTPUT 1
Type: relay SPDT contact (NO or NC selectable
by jumper).
Contact rated: 3 A at 250 V AC on resistive load.
Output cycle time:programmable from 1 s to
200 s.
Function: programmable as heating or cooling
output
OUTPUT 2
Type: relay SPST contact .
Contact rated: 2 A at 250 V AC on resistive load.
Function: programmable as:
- control output ( cooling)
- Alarm 1 output
Output cycle time (when used as control output):
programmable from 1 s to 200 s.
OUTPUT 3
Type: relay with SPST contact
Contact rated: 2 A at 250 V AC on resistive load.
Function: Alarm 2 output.
ALARMS
Actions: Direct or reverse acting.
Alarm functions: each alarm can be configured
as process alarm, band alarm or deviation alarm.
Alarm reset: automatic or manual reset
programmable on each alarm.
Stand by (mask) alarm: each alarm can be
configured with or without stand by (mask)
function.
This function allows to delete false indication at
instrument start up and/or after a set point
change.
Process alarm:
Operative mode : High or low programmable.
Threshold : programmable in engineering unit within
the input span.
Hysteresis: programmable from 0.1 % to 10.0 % of
the input span (P4 - P3).
Band alarm
Operative mode: Inside or outside programma-
ble.
Threshold : programmable from 0 to 500 units.
Hysteresis : programmable from 0.1 % to 10.0 % of
the input span.
Deviation alarm:
Operative mode : High or low programmable.
Threshold : programmable from - 500 to +500 units.
Hysteresis : programmable from 0.1 % to 10.0 % of
the input span.
