1.1
Spare Capacity and Expansion
Capability
Reference material
specifications 23-SAMSS-050 section
on Spare Capacity and Expansion Capability in addition to the requirements
below: The spare capacity
shall be distributed equally among plant areas. Spare capacity requirements
shall be demonstrated as part of the Performance Test. The TMS system shall
be delivered to the installation site with the following minimum spare capacity
and expansion capability.
Table 2 : Equipment
Spare and Expansion Capacity
Expansion
Capabilities: The system design
shall include the capability for future hardware expansion as listed in the
above table, which shall be achieved by addition of equipment, without
modifying or replacing existing equipment, communication cables or system
operating software. It shall not be required to shutdown the complete control
system while it is incrementally expanded The system
processing (CPU), disk, and memory capacity shall have expansion capability for
future application programming and configuration including, but not limited to,
the following: ·
Alarming Monitoring; ·
Equipment Monitoring; ·
Trend and history collection; ·
Reports; ·
Displays, including user-defined graphics displays.
1.2
Time Synchronization
The TMS shall have the capability to be
maintained in time synchronization with the Host system. The Host system shall
be the master.
Within the LAN, the
TMS server shall be the master maintaining time synchronization for all devices
connected. FUNCTIONAL SPECIFICATION FOR TERMINAL MANAGEMENT SYSTEM (TMS) part 6 1.3
Engineering Units
All dimensions and
measurements for project specific documentation shall be identified by the
System International (SI). Non-critical
dimensions may be rounded off to the nearest practical value unit. This requirement does not apply to vendor
standard documentation. Engineering units
used by the system shall be as shown in the following table: Table 3 : Engineering
Units
Any deviations from
or additions to the above list shall be approved, in writing, by HVACMEP.SITE. 1.4
Environmental Conditions
The system shall be
capable of operating continuously when subjected to the environmental
conditions at the installation site. The
installation site environmental conditions are as shown in engineering
specifications HVACMEPES-A-112. FUNCTIONAL SPECIFICATION FOR TERMINAL MANAGEMENT SYSTEM (TMS) part 6 1.4.1
Indoors (Air
Conditioned Buildings)
The equipment
shall not suffer damage during prolonged failure of the air conditioning system
when the ambient temperature may reach 50 °C; and /or the relative humidity,
95%. 1.4.2
Onshore Environment
The normal
air borne dust concentration shall be considered as 1 mg/m3. During sand storm conditions, dust concentrations
up to 500 mg/m3 may be encountered and winds may gust to 150
km/h. Particle size distribution is
95%less than 20 µm, and 50% are less than 1.5 µm. Compounds
present in the dust include those of sodium, calcium, magnesium, silicon and
aluminum. When wetted (100% humidity
condition), these compounds function as electrolytes and may result in severe
corrosion of materials. The
manufacturers standard protective paint finish or coating for the specified
environment shall be applied. 1.4.3
Environmental Conditions
- Severe
Equipment for
outdoor locations shall meet the following requirements: ·
Type 4X per NEMA 250 with the exception that painted or coated carbon
steel sheet material shall not be used. ·
Type 3 or 4 per NEMA 250; manufactured of copper free aluminum. ·
IP64 or better per IEC529; manufactured of stainless steel, copper free
cast aluminum or non-metallic material. In the
hazardous areas (Class I, Div. 2, Group D) the enclosures shall meet the above
ratings in addition to the rating required for the hazardous area. 1.5
Electrical Power
All TMS VENDOR
supplied electrical equipment shall conform to the National Electrical Code,
NFPA 70. 1.5.1
AC Electrical Power
AC electrical power will be
provided from UPS sources at 120 VAC 60 Hz single phase. The TMS VENDOR shall
supply the UPS systems in conformance with engineering specifications HVACMEPESP103
“Direct Current and UPS Systems” and as specified in this document under
Uninterruptible Power Supplies section. The TMS VENDOR shall
protect each device with a direct AC power input by a circuit breaker or fuse
installed in the live line. Individual thermal
and/ or magnetic type circuit breakers shall be in the line, supplying power to
the primary of each power supply. In low
current applications, where a circuit breaker is not practical, a fuse may be
used. Each panel mounted
circuit breaker or fuse shall be tagged with a permanently mounted nameplate
that identifies its service. AC
electrical power will be available for all equipment supplied by the TMS VENDOR. If any other supplies are required for any
equipment within the scope of the TMS VENDOR, the TMS VENDOR shall provide
power supplies mounted within system cabinets. 1.5.2
DC Electrical Power
Each cabinet and the
TMS servers shall be provided with power supplies for all DC voltages. Failure of any DC power supply shall cause a
system alarm. Circuit protection shall
be provided. FUNCTIONAL SPECIFICATION FOR TERMINAL MANAGEMENT SYSTEM (TMS) part 6 1.6
RFI Immunity
RF sources such as
hand-held transceivers operating at 5 watts, in the 150 to 170 and 450 to 470
MHz bands and at a distance of three meters from the equipment (with cabinet
doors closed) shall not cause a signal disturbance of more than 0.1% of range
when keying or transmitting. Furthermore, RF sources
at the above power and range shall cause no addition or loss of pulses from
metering, no effect on meter counting and no effect on the operation of the
computer system or peripherals. 1.7
EMI Generation
Each item of
equipment shall not generate radiated electromagnetic emissions in excess of
the values recommended by ANSI C63.12 and shown in the table below, as measured
30 meters from the equipment enclosure. Table 4 : Allowable
EMI Generation
