1 Safety Precautions
AQ1000 arc quenching device is intended for making low-impedance short circuit between all
the phases and ground, which is comparable to bolted short circuit to ground.
Installation shall not be done before the entire system has been verified to withstand bolted short
circuit. This verification shall include, but not limited to:
•Source transformers and generators
•PT’s, CT’s, VT’s
•Circuit breakers
•Busbars and cables
•Busbar insulators and supports
•Switchgear structure
During tripping, equipment can exceed noise level 85 dB(A). Wearing of hearing protection, is
recommended when making commissioning tests or when operating with the device.
Before installation, it shall be verified that there is no intentional live feed or un-intentional back
feed to the busbars.
Read these instructions carefully and inspect the equipment to become familiar with it before
trying to install, operate, service or maintain it. Electrical equipment should be installed,
operated, serviced, and maintained only by qualified personnel. Local safety regulations should
be followed. No responsibility is assumed by Arcteq for any consequences arising out of the use
of this material. We reserve right to changes without further notice.
Device should not be removed, or any other service works done when the energy storage
component is charged. See chapter 3.1 Operating modes for more information regarding
operation.

2.4 Device Grounding
The grounding of the device is connected to the device chassis. When grounding the AQ1000 device, attention shall be paid for verifying
adequate grounding is existing in switchgear.
This grounding connection can be used when grounding was found inadequate.

3 Operation
AQ1000 contains no user settable or application dependent parameters or values.
3.1 Operating modes
Mode
Definition
Charging
In charging mode, the device charges the energy storage with sufficient energy to move the contacts to the closed
position. During normal operation, the charging occurs several times in hour as the charged energy level is constantly
monitored and adjusted. During charging, the indication LED in the front panel is on.
Ready
In ready mode, the device’s energy storage is charged to sufficient energy level and device is ready to operate.
Trip
In trip state, the device has operated, and energy storage is empty. In trip mode, the LED indicators are showing trip
and closed state.
Blocked
Blocked mode occurs when the binary input 4 is energized. During blocking the movement of quenching contacts is
prevented.
Discharging
Discharging mode occurs when the device auxiliary power is disconnected. In discharging mode, the energy storage is
safely discharged. LED indicator is showing the discharging mode until safe voltage level is reached and indicator turns
off. Refer to chapter 6 Technical data for discharging time specification.
Commissioning
When performing commissioning or periodical testing commissioning mode is recommended to be activated by
energizing binary input 2. In commissioning mode, device internal operation counter is blocked.
(When allowed maximum number of operations is reached maintenance alarm is activated automatically. User should
contact Arcteq technical support when maintenance alarm is constantly active and binary input 2 is de-energized.)
Maintenance Contac Arcteq technical support for further instructions.

3.3 Binary Input Functions
Input
Function
BI1 - Clear input
Clear / reset the indications after error or trip event.
BI2 - Maintenance
In maintenance mode device internal operation counter is blocked.
-
Not used. (Reserved for future purposes.)
BI4 - Block input
Blocks the trip contact activation during commissioning or any other circumstances where the tripping shall be
prevented. See also chapter 4 Commissioning for using binary input 4 for testing / commissioning purposes.
3.4 SET Button
AQ1000 contains a SET button in the front panel, which is used for resetting the indicators after trip event and to clear the alarm signals.
Figure 3-2: SET button.
After the trip, restoring of quenching contacts to open position shall be done before pressing the SET button or
activating external clear signal by energizing binary input 1.
3.4 Self-supervision functions
Fiber connection lost:
When fiber connection is lost from either Com1 or Com2 port, error led turns ON and ready led turns OFF. Corresponding fiber led is blinking
(COM1 or COM2) indicating faulty connection channel. Simultaneously self-supervision contact changes status indicating system alarm.
After connection is restored, blinking COM led may be cleared by using the SET- button or clear input (BI1).
Temperature too low or high:
When temperature is out of device allowed temperature range (-10 C … +75 C) error led turns ON and ready led turns OFF. Simultaneously self-
supervision contact changes status indicating system alarm. After temperature returns to allowed range, device automatically switches to normal
state causing error led is switched OFF, ready led ON and self-Supervision contact changes status indicating system healthy.
Capacitor condition alarm:
In case device energy storage capacitance drops below 85% of nominal value maintenance mode is activated. User should contact Arcteq
technical support for further instructions.

3.5 Restoring quenching device contacts
After arc flash incident restoring of arc protection system and quenching device must be done carefully and systematically.
Always follow equipment manufacturers and national instructions, safety policies and regulations.
Locate and remove the cause of fault.
•Restore quenching device contacts to open position by using the reset handle (see Figure 3-3: Reset of contacts.)
•Reset and clear indications of arc protection system with set buttons.
It is recommended to use the ready contact of AQ 1000 as lock out signal for the circuit breaker. This will prevent the
closed operation of the circuit breaker when the AQ1000 is in closed position or not ready to operate.
When a trip has occurred, the quenching contacts must be restored to the open position by using the handle provided with the device starting
from handle position 1. Device is reset, when shaft is moved to complete open position using handle position 3 and then pressing the clear
button. See figure below. Device indicates the open position with LED indicators.
Figure 3-3: Reset of contacts.
Remove the handle after reset. If not removed the handle may fly off from its slot in event of trip and cause harm or
damages.
Never attach the handle to device when shaft is in open position.
