SETPOINTS
VFR Voltage Frequency Relay
6.10
Instruction Manual: VFR GBM 06/10/2021
Frequency Protect.
df/dt 1 Startup
Value
59.8 Hz
(*)
RANGE: 48.0
60.0
STEPS: 0.1
The df/dt protection is inhibited when the frequency values is greater than this
value.
[6.5

Frequency Protect.
df/dt 2 Delay
Value
0.15 s
(*)
RANGE: 0.01
60.00
STEPS: 0.01+ 0.1
Enter the
df/dt
2 protection intervention delay.
The Trip time will be the sum of the delay time and the time required by the relay
for measuring df/dt value [6.2 Setpoints: SYSTEM SETUP: df/dt Cycles].

6.6 Setpoints: OUTPUT RELAY
Before connecting the output contacts, verify
1.8 SPECIFICATIONS
, with special consideration for Max Switching
Voltage, Rated Load and Max Continuous Current of each Aux.
In case of fault condition, the output relay associated to the active protection function will act (it will go from a Non-Operating
State to an Operating State) and the Trip Led will turn ON.
Output Relay
Aux1 Output Relay
Value
LATCHED
RANGE: LATCHED
-
LATCHED: once the associated protection has intervened, the Aux1 output
relay will function in Operating State.
When the fault condition ceases, it is necessary to manually RESET.
Output Relay
Aux2 Output Relay
Value
LATCHED
RANGE: LATCHED
-
LATCHED: once the associated protection has intervened, the Aux2 output
relay will function in Operating State.
When the fault condition ceases, it is necessary to manually RESET.
Output Relay
Aux3 Output Relay
Value
LATCHED
RANGE: LATCHED
-
LATCHED: once the associated protection has intervened, the Aux3 output
relay will function in Operating State.
When the fault condition ceases, it is necessary to manually RESET.
Output Relay
Aux4 Output Relay
Value
LATCHED
RANGE: LATCHED
-
LATCHED: once the associated protection has intervened, the Aux4 output
relay will function in Operating State.
When the fault condition ceases, it is necessary to manually RESET.
Output Relay
Aux5 Output Relay
Value
LATCHED
RANGE: LATCHED
-
LATCHED: once the associated protection has intervened, the Aux5 output
relay will function in Operating State.
When the fault condition ceases, it is necessary to manually RESET.
Output Relay
Aux6 Output Relay
Value
LATCHED
RANGE: LATCHED
-
LATCHED: once the associated protection has intervened, the Aux6 output
relay will function in Operating State.
When the fault condition ceases, it is necessary to manually RESET.
