8.1.2 Binary outputs

The unit has one (1) binary output: BO1 (+24 VDC). The binary output function can be configured with

the DIP switches. For more information on the configuration, please refer to the "DIP switch settings"

chapter.

Please note that the binary ouput is polarity-sensitive (see the "Wiring" chapter for more information).

8.1.3 System failure relay

The system failure (SF) relay is of the change-over type (NO/NC) and it is energized when the unit is in

a healthy condition. Whenever the unit detects a system error or a disconnection between the auxiliary

power supply and the contacts, the SF relay changes its state. The state stays this way until the unit

returns to a healthy condition and the SF relay is energized again.

8.2 Inputs

8.2.1 Arc sensor channels

Both AQ-101 and AQ-101D have four (4) arc point sensor channels: S1, S2, S3 and S4. You can

connect a maximum of three (3) arc point sensors to each channel.

S5 is the optional fiber optic loop sensor channel with a transceiver (Tx) terminal and a receiver (Rx)

terminal. When the fiber optic loop sensor is connected to the unit, one of its ends is connected to "Tx"

and the other to "Rx". This sensor loop is then continuously monitored by a test light pulse that travels

through the loop. If a discontinuity is detected, the unit goes into Error mode and activates the "Error"

LED and the SF relay output.

For more information on sensors, please refer to the "Arc sensors" chapter as well as to the AQ-0x

instruction booklet which can be found on Arcteq's website (

https://www.arcteq.fi/downloads/

).

8.2.2 Binary inputs

This unit contains two (2) binary inputs.

BI1 is always reserved for the signal from the secondary trip criterion. Typically, the unit receives

overcurrent information from an AQ-110x unit, although such information can also come from a non-

Arcteq device (such as an upstream protection relay). Alternatively, any other signal (such as

undervoltage) can be used as a secondary trip criterion along with light information.

Please note that when this unit receives an overcurrent signal from a non-Arcteq device, the actual

operating time depends on the operating time of the third-party device. Therefore, the total operating

time cannot be specified nor guaranteed.

BI2 can be used for receiving a trip signal or an arc light signal. The function of the BI2 is configured

using the DIP switches. For more information, please refer to the "DIP switch settings" chapter in this

manual.

The binary inputs are activated when a connected DC signal exceeds the specified nominal threshold

level of the corresponding input. There are three (3) different nominal threshold levels

available: 24, 110, or 220 VDC. Please note that the threshold value must be chosen and specified

when ordering the unit. Please note that the actual activation of the binary input occurs earlier than the

specified nominal threshold value (see Chapter 11.4, "Techical Data").
