Configuration
The configuration defines the protection behaviour when the activation threshold and the time
delay are reached.
Trip Circuit breaker tripping
Alarm Alarm without tripping the circuit breaker
O Protection deactivated (default setting)
Inhibition
This parameter allows the protection action to be inhibited temporarily based on a command
sent in one of the following ways:
- sentinel Energy display from the MODE menu
- Hager Power setup software (Commands menu)
- Digital input (DI): assignment of the digital input to the inhibition required
- Modbus communication.
On The protection is inhibited while the inhibition command is at On
O The protection is fully operational while the inhibition command is at O
Activation threshold
The activation threshold is expressed as a percentage of Pn, configurable rated power (see
chapter 6.12 Electrical grid parameters).
Adjustment range: 4.0 to 15.0 x Pn in increments of 0.5.
Precision of the activation threshold: 0% to -20%.
Activation time delay
Adjustment range: 0.5 to 25 s in increments of 0.5.
Precision of the activation time: - 15 % to + 15 % + 100 ms.
Minimum tripping time: 425 ms.
Maximum tripping time: 675 ms with time delay set to 0.5 s.
