Emergency / Safety Loop — BOGE airtelligence provis 3 Fault Code

BOGE airtelligence provis 3

provis is a MASTER controller, not a machine controller — each compressor keeps its own focus control or equivalent for safety shutdowns. The master only requests load/unload.

Manufacturer

BOGE

Display

10.1" color touch panel (provis 3); 5.7" on provis 2.

Years produced

provis 2 ~2012 – 2020; provis 3 ~2020 – present.

Power supply

100 – 240 VAC panel supply, internal 24 VDC bus.

Ambient range

0 – 45 °C.

Protection rating

IP54 front on wall-mount enclosure.

Relay outputs

Per-compressor enable relays, common alarm, dryer/dryer-bank enable.

Replaces

airtelligence provis 2, airtelligence 1

Used on

Mixed BOGE fleets
Third-party compressors via volt-free / Modbus interface

Features

Master sequencing / band control for up to 16 compressors (4 VSD)
Predictive load management — starts the next machine before pressure drops out of band
Energy and specific-power reporting (kWh per 100 m³ / per 100 cfm)
Zone pressure control with independent setpoint bands
Leak and off-shift consumption trending

Interfaces

Ethernet Modbus TCP
Profinet / Profibus (option)
RS-485 Modbus RTU
Web browser dashboard
BOGE connect cloud link

Sensor inputs

Network pressure (up to 4 zones)
Flow / dew point (option)
Compressor status via bus or volt-free contacts

Fault code lookup

Bus Timeout / Comm Error One compressor stopped answering on Modbus.

First checks

Verify slave address is unique
Check 120 Ω termination at both ends only
Confirm baud/parity match at the machine controller

See trigger conditions & affected models →

Pressure Sensor Fault Network pressure transducer open or out of range.

First checks

4–20 mA loop check at the master terminal
Isolation valve on the sensing line closed?
Compare against a calibrated gauge

See trigger conditions & affected models →

Pressure Band Not Held Demand exceeds installed capacity or a machine won't load on command.

First checks

Check each unit is in REMOTE / bus mode
Verify no local unload setpoint below the master band
Look for a large leak or a new demand

See trigger conditions & affected models →

Compressor Not Available Unit reports fault, local mode, or is locked out at the master.

First checks

Read the fault at the machine controller
Confirm the unit is enabled in the master schedule

See trigger conditions & affected models →

Emergency / Safety Loop External safety input open.

First checks

Check remote loop wiring / jumper

See trigger conditions & affected models →

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

Wall-mounted panel — keep the Modbus trunk daisy-chained, never a star topology
Volt-free interface for non-BOGE machines: one enable output per compressor plus a run-feedback input
Network pressure sensor belongs downstream of the dryer and receiver, in stable flow, not on a dead leg

Known issues & field notes

Mixing bus-controlled and contact-controlled machines can cause hunting if local unload setpoints overlap the master band — stagger local setpoints above the master band
provis 2 web UI needs legacy Java/older browsers; provis 3 is HTML5

Operator / service / administrator levels set at commissioning. Administrator level is dealer-held.
