Description
0x0000 Relay OFF This setting deactivates the relay.
0x0001 Overload release (0 -> 1): trip - overload
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped due to
an overload. This includes tripping due to the overload
characteristic or to excessive temperature.
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface.
0x0002
Neutral conductor trip (0 -> 1): trip - neutral
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped due to
a neutral conductor trip. The relay will drop out once the
device has been reset or a reset command has been
issued via the communication interface.
0x0003
Short-circuit trip (0 -> 1): trip - short circuit
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped due to
a short circuit. This includes short-time delayed tripping,
instantaneous tripping or an override.
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface.
0x0004
Short-time delayed trip (0 -> 1): trip - short-time delayed
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped due to
a short-time delayed short circuit.
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface.
0x0005
Instantaneous trip (0 -> 1): trip - instantaneous
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped due to
an instantaneous short circuit.
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface.
0x0006 Ground-fault trip (0 -> 1): trip - ground fault
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped due to
a ground fault. The relay will drop out once the device
has been reset or a reset command has been issued via
the communication interface.
0x0007
Trip due to maintenance
mode
(0 -> 1): trip - ARMS
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped due to
maintenance mode.
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface.
0x0008
General trip alarm
Default setting for relay 1
– for breakers without
maintenance mode
(0 -> 1): trip - general trip
(1 -> 0): status - device has been reset
The relay will respond if the breaker has tripped (trip
reasons 4-10).
The relay will drop out once the device has been reset or
a reset command has been issued via the
communication interface.
0x0040
Load alarm 1
Default setting for relay 2
– for breakers without
ground-fault protection
(0 -> 1): alarm - load is active
(1 -> 0): alarm - load is not active
The relay will respond if load alarm 1 is active.
The alarm can be set to between 50 % and 120 % of I
r
.
The relay will drop out again with a hysteresis of 5 %
below the set threshold value.
Default settings: 85 %
0x0041
Load alarm 2 (0 -> 1): alarm - overload is active
(1 -> 0): alarm - overload is not active
The relay will respond if load alarm 2 is active. The
alarm can be set to between 50 % and 120 % of I
r
.
The relay will drop out again with a hysteresis of 5 %
below the set threshold value.
Default settings: 105 %
