| Note: 1. Y the function is available, N the function is not available |
| 2. In the circuit of three phase four wire, the relay which have no phase sequence protection function can be used to protect single phase or two phase circuit. |
|
| 3. All models relay can be adjusted in 220V/230V/240V or 380V/400V/415V except RV2 -07, RV2 -08 |
Description of panel diagram:
I. Function indicator lamp:
a. Power indicator lamp: indication of power supply for relay
b. Normal: no fault of relay indicated
c. Operation: output relay operation indication
d. Over-voltage: over-voltage fault indication
e. Under-voltage: under-voltage fault indication
f. Phase dislocation: indication of input phase sequence errors
g. Phase failure: indication of phase failure fault
h. Unbalance: three-phase imbalance fault indication
i. Over-voltage/under-voltage: in case of over-voltage fault, the indicator lamp would be constantly ON; in case of under-voltage,
the fault indicator lamp would flash.
j. Over-voltage/under-voltage/recovery: when overvoltage fault occurs, the indicator lamp would flash at a high frequency (flash once every
0.3s); in case of under-voltage fault, the indicator lamp would flash at a low frequency (once every 1.5s); in case of recovery delay, the indicator lamp would be constantly ON.
II. Setting knob:
a. ×Ue: knob for setting of threshold values of over-voltage (1.05~1.30) or under-voltage (0.70~0.95)
b. T(s): operation time delay adjusting knob 0.1s~10s
c. Over_t(s): over-voltage operation time delay adjusting knob 0.1s~10s
d. Under_t(s): under-voltage operation time delay adjusting knob 0.1s~10s
e. Asm (%): knob for setting of threshold value of unbalance 5%~15% Over-voltage threshold value = set value × Ue,Under-voltage threshold value = set value × Ue
