Lovato ADXL0115600 Soft Starter 115 A with Built-in Bypass

Lovato ADXL0115600 soft starter, 115 A with built-in bypass

The Lovato ADXL0115600 is a 115 A soft starter with built-in bypass for three-phase motors on supplies of 208 to 600 V AC. Under IEC conditions it handles 55 kW at 400 V, 75 kW at 500 V and 37 kW at 230 V. Seven Star LLC supplies the ADXL0115600 in Oman and the GCC as an independent supplier in Muscat.

The code follows the ADXL pattern: 0115 gives 115 A and 600 the voltage class. Compared with the ADXL0060600 it is a larger body of 95 x 226 x 182 mm and 2.9 kg, but the control platform, the display and the protections are shared. That makes it practical to standardise on one family for several pump sizes.

ADXL0115600 technical specifications

Choosing the ADXL0115600 for larger pumps

At 55 kW the motor current approaches the range where direct starting causes voltage dips and mechanical shock. A soft starter reduces both. For a centrifugal pump the torque ramp gives a smooth acceleration and, with a soft stop, avoids the pressure surge on shutdown. For a compressor or conveyor the constant-torque start with current limit keeps the line current within the utility or generator limit.

Heavy starts raise the thyristor temperature. The thermal capacity depends on the starting current, the start time and the number of starts per hour, so a long start of 30 seconds at 4 times current requires a check against the manual curves or a larger unit.

Protection and diagnostics in the ADXL0115600

Besides motor overload, locked rotor, phase loss, asymmetry and dry-run detection, the starter reports its own faults: overtemperature of the thyristors, bypass failure and fan faults. The event log records the cause and a snapshot of values, which is valuable when a plant operator reports a trip without knowing why. A maintenance counter requests service after a set number of starts or hours.

Neighbours of the ADXL0115600

The ADXL0085600 handles 85 A and the ADXL0135600 handles 135 A, so a 55 kW motor with a high current can be matched to either size depending on nameplate. Above this range the ADXT family takes over with its 3-phase control and forced cooling.

ADXL0115600 selection checklist

• Motor nameplate current and whether it is under 115 A
• Supply voltage and frequency
• Starting time and starts per hour
• Auxiliary supply of 100 to 240 V AC
• Cooling: natural or optional forced
• Panel temperature and altitude derating
• Available space of 95 x 226 x 182 mm

Installing and commissioning the ADXL0115600

Use the screw fixing or rail with the accessory, observe the clearances above and below for airflow, and wire line to the top and motor to the bottom as marked. Protect the starter with semiconductor fuses when coordination type 2 is wanted.

Set rated current, ramp times, current limit and trip class at the keypad. Verify the direction of rotation first on a bump start, then run the pump with the discharge valve in its normal start position. Record the settings.

Typical ADXL0115600 applications in Oman and the GCC

Typical uses are large water transfer pumps, desalination feed pumps, fans in tunnels and industrial buildings, and process compressors. The ability to limit starting current is valuable in remote sites supplied by diesel generators, where a hard start can cause a trip of the whole set.

A final point on coordination: the starter does not replace the short-circuit protection of the feeder. A fuse or breaker of the correct rating must still sit upstream, and when the plant requires the starter to survive a fault, semiconductor fuses chosen from the manufacturer tables are normally specified. Cable sizing follows the motor current, not the starter rating, so a 100 A motor on this starter needs a cable for 100 A at the site temperature. Keep a copy of the programmed parameters with the panel documents, because a replacement unit can then be set up in minutes.

Site conditions in Oman for the ADXL0115600

Low-voltage switching and protection devices in Oman often sit in motor control centres and outdoor panels where internal temperatures are high for much of the year. When you select the ADXL0115600, check its rated values at your real ambient temperature, as stated in the manufacturer documentation, and confirm the coordination with upstream protection and with the motor or load it serves. Short-circuit levels differ from site to site, so verify the breaking capacity required at the point of installation.

Standardising ratings and coil voltages across a project reduces the number of spare part numbers that need to be stocked. Keeping a small stock of the ADXL0115600 and recording settings such as trip ranges or ramp times shortens repair work during a breakdown.
