The arc protection card has four (4) sensor channels, and up to three (3) arc point sensors can be
connected to each channel. The sensor channels support Arcteq AQ-01 (light sensing) and
AQ-02 (pressure and light sensing) units. Optionally, the protection function can also be applied with a
phase current or a residual current condition: the function trips only if the light and overcurrent
conditions are met.
The outputs of the function are the following:
• Light In
• Pressure In
• Arc binary input signal status
• Zone trip
• Zone blocked
• Sensor fault signals.
The arc protection function uses a total of eight (8) separate setting groups which can be selected from
one common source.
Table. 5.4.13 - 136. Output signals of the IArc>/I0Arc> function.
Outputs
Activation condition
Channel 1 Light In
Channel 2 Light In
Channel 3 Light In
Channel 4 Light In
The arc protection card's sensor channel detects light.
Channel 1 Pressure In
Channel 2 Pressure In
Channel 3 Pressure In
Channel 4 Pressure In
The arc protection card's sensor channel detects pressure.
ARC Binary input signal
The arc protection card's binary input is energized.
I/I0 Arc> Ph. curr.
START
I/I0 Arc> Res. curr.
START
The measured phase current or the residual current is over the set limit.
I/I0 Arc> Ph. curr.
BLOCKED
I/I0 Arc> Res. curr.
BLOCKED
The phase current or the residual current measurement is blocked by an input.
I/I0 Arc> Zone 1 TRIP
I/I0 Arc> Zone 2 TRIP
I/I0 Arc> Zone 3 TRIP
I/I0 Arc> Zone 4 TRIP
All required conditions for tripping the zone are met (light OR light and current).
I/I0 Arc> Zone 1
BLOCKED
I/I0 Arc> Zone 2
BLOCKED
I/I0 Arc> Zone 3
BLOCKED
I/I0 Arc> Zone 4
BLOCKED
All required conditions for tripping the zone are met (light OR light and current) but the tripping is
blocked by an input.
I/I0 Arc> S1 Sensor fault
I/I0 Arc> S2 Sensor fault
I/I0 Arc> S3 Sensor fault
I/I0 Arc> S4 Sensor fault
The detected number of sensors in the channel does not match the settings.
I/I0 Arc> IO unit fault
The number of connected AQ-100 series units does not match the number of units set in the
settings.
The operational logic consists of the following:
