Ensure that the equipment is depressurised and electrically isolated prior to carrying out any of the
scheduled maintenance instructions specified within this user guide.
3.3 External Power Supply – 230v and 110v operation
In the event of a hazard or malfunction, the power should be switched off at the socket before being unplugged
from the mains.
The power lead should only be plugged into the air receiver power input socket. Check to ensure your electricity
supply matches that shown on the rating plate.
The power supply will provide adequate power for the instrument. The user should ensure that all other auxiliary
apparatus, drawing power from the host, does not overload the power supply.
A damaged mains cord should be replaced by the user.
The air receiver and controller operate on a 24v DC supply, managed by a power supply unit built into the air
receiver body that accepts a 110/230v universal input. The power to the controller is delivered via power over
ethernet (PoE). A relay within the air receiver assembly separately diverts the mains 110/230v supply directly to
the compressor via the 'power out' port on the air receiver top plate. In order for the system to safely operate
at either a 110 or 230 voltage, the compressor pump motor must be rated to the correct corresponding input
voltage. A 230v compressor is supplied with a Pulse 2.0 system as standard but a 110v version of the same
compressor is also available upon request.
3.4 Connections
Interconnection to other equipment via the externally accessible ports or wireless connectivity on the
instrument must only be made as follows:
Power Supply Input and compressor power output: As described in Section 3.3
USB: A storage device can be used to export test data as per the export protocol detailed in Section 8.3.1. It is
strongly suggested that any storage device connected to the Pulse Control Unit is scanned for viruses or,
preferably, formatted before use. The Pulse control software may not have sufficient malware protection to
prevent the software being altered or deleted by any malware present on an inputted USB device, requiring the
unit to be returned to the service provider for repair.
Ethernet: To connect from an air receiver to the controller and/or from an air receiver to an additional auxiliary
air receiver. All described in section 7.3.
