THRESHOLD VALUE FOR BREAK-DOWN ALARM
(available only if HCEn = On)
Upper Display
Lower Display
Range
0 ↔ FULL SCALE (see HCHS)
Note
When the output that is added to the current transformer is in excited state of relays, the
•
instrument measures the current absorbed by the load and generates an alarm if the current is
below the value of Hbd parameter (a low current indicates a break-down partial or full load).
The resolution of the threshold value is equal to 0.1A for range up to 20A, 1A to 20A to 100A

range.
HYSTERESIS VALUE FOR BREAK-DOWN ALARM
(available only if HCEn = On)
Upper Display
Lower Display
Range
0 ↔ 1.0
THRESHOLD VALUE FOR SHORT CIRCUIT ALARM
(available only if HCEn = On )
Upper Display
Lower Display
Range
0 ↔ FULL SCALE (see HCHS)
Note
When OUT1 relay is in unexcited state, the instrument measures the leakage current in the load and
•
generates an alarm if the current exceeds the value of the parameter SCA (a high current indicates a
partial break or total of the relay or SSR).
The resolution of the threshold value is equal to 0.1A for range up to 20A, 1A to 20A to 100A range.
