Configurable Alarms
Alarm is assigned to an output, configurable as: maximum, minimum, sym-
metrical, 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
Selection with Dip-Switches
4 loads single-phase,
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)
