CIBSE COMMISSIONING CODE R PDF

Vonos Check that all outstations and unitary control devices can be addressed and data sent and retrieved. Implementation of post occupancy checks to confirm the performance of the control system and the attainment of required internal environmental conditions. Note that flash tests should be performed for mains powered equipment only. Interlocks Specific plant commissioning This section provides commissioning details for basic plant items such as fans, pumps and terminal units etc. However, the sensors should be checked commissionong accuracy and for position to ensure that readings are representative of the temperature within the space. Note rhar under some control strategies the cooling damper may be modulated during optimum start.

Sajas The calibration should take place at the lighting controller or operator workstation via configuration software. Control problems such as excessive plant cycling will have an adverse effect on control components such as actuators, while the excessive switching on and off of the plant will increase their maintenance requirements and shorten their operational life.

Set points and other control settings such as initial default parameters for control loops relating to the control strategies. Functional requirements of any occupant interfaces. Shrouding of switches, lamps etc on doors if low voltage. Tuning of control loops 31 34 34 34 35 35 35 CA2. Switch the fan to automatic control and check the operation of the fan speed control by forcing the output via the application software. While novel control strategies may be required for certain applications their use will often complicate the commissioning process.

Ensure that each check is entered on the relevant checklist. Check that a fire alarm condition automatically displays the appropriate building commissoning and alarm status if specified. Check that the valve has the correct mnemonic displayed. Check all safety interlocks, e. Manual dimming cise C6. Check that the low inside air temperature signal is independent of both the low outside air temperature and low primary heating return water temperature signals and that it takes priority over these two signals.

Shrouding and labelling of non-isolated equipment. Check the sensors in situ if possible at normal operating conditions using a calibrated instrument. Check the operation of the air flow failure device by-simulating a. When used i n conjunction with an office IT network ensure that permission has been granted from the IT manager.

The main items of plant affected by seasonal influences are: The Code therefore gives the strongest encouragement to designers and clients to consider commissioning at the earliest stages, and to seek specialist input early in the life of the project. Check that the ccibse coil valve is fully open when the control system signals a boost or optimum heating start operation.

Provision of suitable gland plates. The controllers coce independently of each other and there is n o permanent operator workstation.

Integration between a BMS and intruder detection system usually involves the provision of a supervisory monitoring facility that transfers monitored data from an autonomous intruder detection system to the BMS operator workstation. Check that any specified out-of-occupancy periods, weekend and holiday time schedules operate correctly note that the current operating date can be changed to simulate weekend and holiday dates.

Automatic controls Check that the speed of communications meets that specified. Note that external switches and pots can be connected to a simulator for test purposes. Check that equipment that requires on-line adjustment and testing by non-electrically qualified personnel is accessible and usable without interrupting the supply or overriding the safety interlocks. Ductwork air leakage commissionng, if specified, has been performed.

The commissioning of the control system can be simplified if the commissioning of the building services systems are simplified. The chance was also taken to reflect the growing realisation that many key decisions relating to the construction process are taken in the very early stages of a project. Clients should be made aware that any reduction in commissioning cibze will invariably result in future operational problems relating to the control system.

Tygogul Where metering is restricted to the measurement o the total utility consumption, f estimates will have to be made of utility consumption resulting from building services plant. Ensure that the rangeability of the selected valves is large enough to provide stable control under low load conditions. The control equipment for any main andor critical items of plant should be witnessed completely along with a random sample of other points. Air distribution systems 2 Code B: Check that data communications are error-free, i. During the commissioning period these conditions may not arise due to the building being unoccupied and the impact of seasonal influences, e.
