1 General
1.1 Device Overview
The power and communication unit (PCU) is an intrinsically safe, IEEE 802.15.4 2.4GHz device. The PCU
can be paired with additional sensors which are capable of detecting the presence of hydrocarbons in the air,
water and ground. Two field-interchangeable sensors provide detection of hydrocarbons, temperature,
inclination, acceleration and liquid height. Sensor measurement readings are communicated along with
network and battery status via the wireless mesh communication protocol. The PCU seamlessly integrates
with existing SCADA and asset management systems.
Sensors approved for use:
Hydrocarbon liquid and vapor detector (HCD)
Hydrocarbon liquid and vapor detector with a water level sensor (HCDW)
WARNING: Only sensors provided by Syscor are compatible with this device.
WARNING: Do not attempt to disassemble the sensors as this could damage the sensor, void
hazardous location approvals and the manufacturer’s warranty.
WARNING: Device protection may be impaired if used in a manner not specified by Syscor.
WARNING: Do not open in an explosive gas atmosphere.
1.2 Device Approvals
1.2.1 Intrinsic Safety
The PCU, HCD and HCDW products have been certified for operation in hazardous locations under the
following parameters and conditions:
Class 1, Division 1, Groups C, and D;
Intrinsically safe Exia;
Ambient temperature range -40°C to +60°C, Temperature Code T4;
PCU enclosure is Type 4X IP67; and
HCD & HCDW enclosures are Type 4X IP68.
Specific Conditions of Use (Antenna):
1) A passive antenna may be supplied by Syscor or provided by the customer. Permitted antennas must
have <10000mm^2 plastic surface when screwed in directly to the enclosure. Antennas mounted via
cable are not subject to the plastic surface area restriction.
2) Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of this
equipment (i.e. a plastic antenna) may generate an ignition-capable level of electrostatic charge.
Therefore, the equipment shall not be installed in a location where the external conditions are
conductive to the build-up of electrostatic charge on such surfaces. In addition, the equipment shall
only be cleaned with a damp cloth.
3) Only battery powered field communicators may be used with the HART maintenance port.
