Rollair Multilogic
Treat these as Atlas-platform machines for diagnostics — the Elektronikon Mk4/Mk5 fault logic and sensor test procedures apply almost directly.

- PT1000 sanity (~1385 Ω at 100 °C)
First checks
- Amps vs plate
- Supply balance
- Element rotation
First checks
- Loop mA
- Connector
- Sensor swap
First checks
- E-stops
- Loop continuity
First checks
- Service per kit
- Reset specific counter
Fault list is non-exhaustive and firmware-dependent. Always confirm against the controller’s on-screen help or OEM manual.
Sensor pin resistance & signal values
Pin-level resistance and signal values for the sensor types this controller uses. Works offline. De-energise the panel and lift one lead before ohming any element.
Wiring notes
- Platform shares Atlas Elektronikon sensor conventions — PT1000, not PT100
- Expansion modules must be power-cycled to enumerate
- Remote start is a maintained contact input
Known issues & field notes
- Spares increasingly sourced through Atlas Copco channels as the Worthington brand winds down
- Menu language can reset to default after EEPROM corruption — note customer language at commissioning
PIN via distributor; shares Atlas group service practices.
