User Guide
ACU 2030
1. Application
The ACU2030 heavy duty level alarm system is designed to operate in conjunction with any level
switch possessing a voltage-free relay output contact.
The unit provides audible and visual alarms of level alarm conditions in tanks, sumps or bund
enclosures. The unit is specifically designed for outdoor mounting and is protected to IP65.
2. Operation
The system consists of the ACU 2030 alarm control unit and any of the Afriso Eurogauge range of
level switches possessing voltage free relay output contacts. The ACU 2030 incorporates both
visual and audible alarms, a set of voltage-free output relay contacts, as well as an alarm Test switch
and an audible alarm Mute switch. When the relay contacts on the level switch change state, due
to the presence of an alarm condition, a DC circuit is completed and the alarm circuit in the
ACU2030 is activated. When an alarm condition is present the red alarm LED will come on, the
sounder will operate and the output relay will energise. Operating the Mute switch will silence the
sounder. Operating the test switch will simulate an alarm condition causing the red alarm LED to
come on, the sounder to operate and the output relay to energise.
3. Installation
3.1 General
The ACU 2030 unit is designed for outdoor mounting on any suitable flat vertical surface. Unscrew
the four captive screws in the lid of the unit and carefully remove the lid. The base of the unit is then
fixed to the mounting surface by means of four screws through the fixing holes in the base of the
unit. Fixing hole spacing centres are 160 x 110 mm and take M4 screws.
3.2 Wiring
Wiring to the ACU2030 alarm control unit must be in suitable cable for the application conditions,
and the installation must comply with all statutory requirements that may affect the complete
installation. The unit must be supplied via an unswitched fuse unit to prevent unauthorised isolation
of the system. Standard electrical installation cable, suitable for the intended supply voltage must
be used and consideration must also be given to any special environmental conditions.
The instrument must be wired in accordance with the wiring diagram.
4. Testing of System Function
Once the unit has been wired up the system function should be tested by operating the test switch.
This will cause the red alarm LED to come on, the sounder to operate and the output relay to energise.
The sounder can be muted by operating the mute switch.
