Failure of a PC, DDC controller, or any other BMS hardware components. Failure of communications between nodes on any LAN or the BMS Management level Network. A monitored status indicates a discrepancy between the actual and the required value. A monitored value does not meet criteria established by the operator. The deviation of a variable from setpoint exceeds operator-established criteria. The output to a final control element is outside operator-established criteria. A digital input is in the state defined by the operator as indicating an alarm condition. Software failures and errors shall be diagnosed and annunciated by the BMS.

B.

The failure of a BMS hardware component, including communications failures, shall generate an alarm that shall be differentiated from process alarms. If the failure of a PC cannot be annunciated at a printer or VDU at the OIW because of the BMS topology then provide an alternative means such as a "watchdog timer" at a DDC controller. The alarm message generated by the BMS shall clearly identify the component that has failed and the location of a communications failure shall also be clearly indicated.

C.

In the event that the BMS detects a disparity between the actual and the required status of a digital input, the BMS shall generate an alarm and shall set the control relay to the off state.


page 29 of 85

This shall occur when the digital output is in both the BMS manual control mode and the BMS software control mode and shall automatically place the output in the BMS manual control mode. D.

The operator shall be able to define alarm conditions for each analog input, at minimum, as follows: 1. The high limit above which the variable is in alarm. 2. The low limit below which the variable is in alarm. 3. An end or range alarm. This shall occur when the analogue signal goes to zero or to its maximum value.

E.

The operator shall be able to assign deviation limits to setpoint values. An alarm shall be generated when a controlled variable deviates from setpoint by more than an operator-defined amount.

F.

The operator shall be able to assign alarm limits to analogue outputs. The BMS shall generate an alarm when an analogue output reaches or exceeds an operator assigned high limit and reaches or goes below an operator assigned low limit.

G.

The operator shall be able to designate one state of a digital input as an alarm state.

H.

These attached examples of component and system test sheets are generic in nature and may not accurately reflect the actual sequences of operation that are to be implemented and not all systems and component types are covered by these example test verification sheets. It is the responsibility of the BMS Specialist to provide test verification sheets for each component and system that accurately reflect the sequences of operation and appropriate data for the components and systems as furnished under this sub-contract.

2.

Completed component test sheets indicating the test results for each BMS component within the system shall be submitted to the Engineer, together with a proposed schedule for system commissioning tests, at least X weeks prior to the proposed system commissioning tests. The Engineer shall determine on the basis of the BMS Specialist's component testing, whether or not it is appropriate to commence system-commissioning tests. It shall be the Engineer’s decision as to whether the system commissioning tests can proceed as proposed by the BMS Specialist or whether deficiencies have to be remedied and additional testing undertaken before the system commissioning tests can proceed.

3.

At minimum, component test sheets will be prepared to cover each of the following items: a.

Digital input point

b.

Digital output point

c.

Analogue input point

d.
