Introduction to connecting your Air Compressor to DRIVE+ or LINK+

Introduction to connecting your Air Compressor to DRIVE+ or LINK+

If you're setting up your system with DRIVE+ or LINK+, it’s important to understand how to correctly connect your air compressors to it. This article gives a clear overview of the connection options depending on your air compressor's power supply, status signals and pressure sensor type. This will help you select the right connection method for your installation.

For detailed wiring diagrams, see the individual Connection Examples linked bellow.

Why are there different connection methods?

Not all compressors are the same. The connection method depends on:
  1. The available power supply
  2. The type of status output signals (relays, digital outputs, or TRIAC outputs)
  3. The type of pressure sensor used (voltage or current based)
The DRIVE+ and LINK+ modules can be flexibly connected using different combinations depending on your compressor’s configuration.

Example Combination

For example, if you have a variable speed air compressor that:
  1. Has a 3-phase + Neutral power supply (360–415 V AC)
  2. Uses TRIAC outputs for status signals
  3. Uses a voltage-based pressure sensor
You would connect as followed:
  1. Use the Power Supply Connection from Example 1 for the 3-phase + Neutral connection.
  2. Use the Status Connection from Example 2 for the TRIAC outputs.
  3. Use the Pressure Sensor Connection from Example 3 for the voltage pressure sensor.
The examples below explain these connection options.

LINK+ Connection Example 1
  1. Power Supply: 3-phase L-L (360–415 V AC) with Neutral available
  2. Status Signals: Digital outputs (relays)
LINK+ Connection Example 2
  1. Power Supply: Separate transformer (400V to 230V, minimum 45 W required)
  2. Status Signals: TRIAC outputs (semi-conductor)
LINK+ Connection Example 3
  1. Power Supply: Separate single-phase 100–230 V AC supply
  2. Status Signals: Digital outputs (relays)

DRIVE+ Connection Examples

DRIVE+ Connection Example 1
  1. Power Supply: 3-phase L-L (360–415 V AC) with Neutral available
  2. Status Signals: Digital outputs (relays)
  3. Pressure Sensor: 4–20 mA
DRIVE+ Connection Example 2
  1. Power Supply: Separate transformer (400V to 230V, minimum 45 W required)
  2. Status Signals: TRIAC outputs (semi-conductor)
  3. Pressure Sensor: 4–20 mA
DRIVE+ Connection Example 3
  1. Power Supply: Separate single-phase 100–230 V AC supply
  2. Status Signals: Digital outputs (relays)
  3. Pressure Sensor: Voltage
