OPERATING PRINCIPLE
The BOSS™ PD-Monitor™ is designed to be a self-contained pressure differential monitor
and alarm signalling device. It has a dedicated up-stream pressure transducer and down-
stream pressure transducer connection to a sealed or open vented system. As system
uid passes through the hydraulic components in the ow sequence below, if the pressure
detected up-stream and down-stream is out of the pre-set parameters within the VEXO
iX-2 Controller, the alarm settings are activated to signal a blockage within the item of
plant the unit is monitoring.

BOSSTM PD-Monitor Operation & Maintenance Manual (V1.0 Feb 2018) Page 11
INSTALLATION
BASIC INSTALLATION REQUIREMENTS
The BOSS ™ PD-Monitor controller unit (item 1) is to be positioned and xed to a sturdy
wall / frame as close as possible to the item of plant to be monitored. The pressure
transducers need to be connected either side of an item of plant which requires the
pressure differential to be monitored. Please note that the pressure transducers are
supplied with a 1.8M ying lead.
The BOSS ™ PD-Monitor controller unit is supplied with a 0.9M ying 2 core and earth
mains cable (item 10). This is to be used to power the unit. This ‘mains’ cable needs to
be connected to a suitable 230V ~ 13A isolator (supplied by others) as a main point of
electrical isolation. The isolator can then be served by a dedicated 240V mains power
supply or, for example a 230V connection from a dedicated pump which supplies the
system in which the BOSS ™ PD-Monitor controller unit is monitoring.
Pressure Transducer 1 (item2) is to be located up-stream of the plant item and Pressure
Transducer 2 (item 3) is to be located down-stream of the plant item. Each pressure
transducer has a 1/4” BSP thread for connecting to the system pipework with a suitable
sealing compound.
Each transducer is connected to the transducer cable via a Packard plug. Ensure the
cables from the Packard plug to the controller unit (item 1) are kept clear of fouling, are
secured to a hard surface, and that any spare cable is coiled and cable-tied. Keep the
transducer cable away from electrical mains cables where possible as this may interfere
with the current and provide false readings.

BOSSTM PD-Monitor Operation & Maintenance Manual (V1.0 Feb 2018) Page 12
CRITICAL INSTALLATION REQUIREMENTS
The equipment must be sited:
• In a frost-free area (>5oC), protected from adverse environmental conditions.
• In a well-lit area to allow for safe maintenance.
• On a at, vertical, level, solid wall or frame with clear access of 200mm all around the

operating mode once power has been restored.
Ensure the power supply to the BOSS™ PD-Monitor™ is 230V ~ 1 N PE 50Hz via a
suitable Fused Spur.
The power supply to the BOSSTM PD-MonitorTM is provided from either a dedicated 240V
power supply or the system pump electrical supply that the BOSSTM PD-MonitorTM is
monitoring. Therefore, the BOSSTM PD-MonitorTM will only be activated when the main
system pump is running and active. The power supply is then connected to the main
BOSSTM PD-MonitorTM Mains Isolation Switch, refer to the unit schematic, item 10 on page 9
(Schematic) of this document. The power is then distributed throughout the BOSSTM
PD-MonitorTM via an internal wiring loom.
2. BOSSTM PD-MonitorTM Specication
• 2No ~ 4-20 milliamp pressure transducers monitor the pressure differential on the
inlet and outlet of the X-POT side stream lter or the item of plant e.g. plate heat
exchanger, pump set etc.
• The VEXO iX-2 12-Volt Controller, with built-in buzzer, is located in the housing box
with a strobe and electrical isolation switch on the front.
