Under Voltage Protection 1

UVP1

Yellow / 1 / High

Protection against over-discharge of the battery. Battery protection was activated.

1. The battery is discharged

1. Charge the battery

Under Voltage Protection 2

UVP2

Yellow / 2 / High

The voltage dropped below 1.9 V which is critical for ASTER to work properly.

1. The battery is discharged

2. The battery is worn out and has too high internal resistance

3. Inadequate battery type for given AEG configuration

4. Too much electrical resistance between ASTER and the battery

5. Motor too strong for the connected battery

6. Motor connections short circuit

7. Motor is jammed

8. Motor is damaged

1. Charge the battery

2. Replace the battery

3. Use a battery with more capacity or more voltage

4. Do not use any adapters

5. Use standard or high-torque motors instead of high-speed

6. Check and fix the motor wires insulation

7. Unjam the motor

8. Replace the motor

Under Voltage Protection 3

UVP3

Yellow / 3 / High

Protection against over-discharge of the battery. Battery protection was activated immediately after connecting the battery.

1. Number of cells is different than their number set in GCS

2. The battery is discharged

1. Set the same number of cells in GCS as in the battery

2. Charge the battery

Motor Disc

MOTOR DISC

Yellow / 4 / High

ASTER did not detect the motor.

1. Motor is not connected

2. Brushes are worn out

3. Motor is damaged

1. Check wiring and motor connectors. Connect the motor

2. Replace brushes

3. Replace the motor

Gear Not Detected

GND

Red / 1 / Low

ASTER did not detect the sector gear.

1. Too high sector gear shimming

2. Sector gear sensor is dirty

3. Sector gear sensor is damaged

4. Sector gear is jammed

5. Motor is damaged

1. Remove shims under the sector gear

2. Clean sector gear sensor

3. Contact 

aster@gatee.eu

1. Inspect the sensors using GCS

2. Replace the motor

3. In case of dirty or damaged gear sensor you may

set Cycle detection to Off

Overload

OVL

Red / 2 / Low

Too high load. The load limit was exceeded.

1. ASTER with BASIC and ADVANCED firmware edition is dedicated for up to mid-tuned guns

1. Use high-torque motor and gears

2. Upgrade firmware to EXPERT

Over Current Protection

OCP

Red / 3 / Low

ASTER detected too high current. Overcurrent protection was activated.

1. Motor is damaged

2. Motor or gearbox is jammed

3. Motor connections short circuit

1. Replace the motor

2. Unjam the motor or gearbox

3. Check and fix the motor wires insulation

Short Circuit Protection

SCP

Red / 4 / Low

ASTER detected current over 220 A. Short circuit protection was activated.

1. Motor is damaged

2. Motor or gearbox is jammed

3. Motor connections short circuit

1. Replace the motor

2. Unjam the motor or gearbox

3. Check and fix the motor wires insulation

Over Temperature Protection

OTP

Red / 5 / Low

ASTER temperature is too high. Over temperature protection was activated.

1. Outside temperature is too high in correlation with the demanding AEG

2. Frequent short circuits and ASTER electrical overloads

1. Wait until the temperature drops

Self-test Failure

STF

Red-Blue / 2 / Low-High

The device failed on self-test.

1. Internal error of the device

1. Contact
