FUNCTIONS
Safety Detects short circuit or open probe circuit, probe ,
power supply failure, LBA alarm, HB alarm
Selection °C/°F Configurable
Linear scale range -1999…9999
Control actions 4 control loops:
Double action (heat/cool) Pid, on-off
Self-tuning at power-up, Continuous Autotuning, One-shot Autotuning
pb-dt-it 0,0...999,9 % – 0,00...99,99 min – 0,00...99,99 min
Action – control outputs heat/cool – ON/OFF, PWM, GTT
Heat/cool max. power limitation 0,0…100,0 %
Cycle time - Softstart 0…200 s - 0,0…500,0 min
softstart at phase slicing
Fault power setting -100,0…100,0 %
Shut-down function Maintains sampling of process variable PV; when active, disables
control
Configurable alarms Alarm is assigned to an output, configurable as:
maximum, minimum, symmetrical, absolute/deviation, LBA, HB
Alarm masking Exclusion at power-up, latch, reset by digital input
Diagnostics SCR in short circuit (presence of current with control OFF)
SCR open (presence of voltage on SCR with control ON)
Load interrupted or no voltage (no current, no voltage on SCR
with control ON)
Connection and load types 4 loads single-phase ,
Selection with dip-switches 2 loads 3-phase, star without neutral controlled on two phases
2 loads 3-phase, closed triangle controlled on two phases
1 load 3-phase, star with neutral controlled on one phase
1 load 3-phase, open triangle controlled on one phase
(with 3-phase load, 4 CTs are needed if diagnostics is required))
