Schedule Title : Introductory Procedures Schedule Ref : 01-01 Schedule Type : Core Schedule Date : 09 Nov 2012 Schedule Version : 1.0.0 Unit of Measure : Not specified Uncontrolled Copy - Printed: 30/11/2015 | Welplan SCHEDULE INTRODUCTIONS The following procedures apply to all types of actuator and require that before any maintenance is undertaken all safety precautions must be strictly adhered to. Care must be taken to ensure that any maintenance does not unduly interfere with the system's environmental conditions. When working on equipment it should be noted that any auxiliaries fitted may have supplies fed from a separate circuit to that of the actuator. Therefore should the actuator supply be disconnected it should not be taken for granted that the auxiliary supply has also been disconnected. To check that the actuator is performing its correct task, it is immaterial as to whether it is mounted on a damper, louvre, valve or any other piece of equipment. Its purpose is to control to a position between two limits, by either opening, closing or moving appropriate pieces of equipment. Other Actuator Types The function of an actuator can be split into two main categories: ON/OFF or MODULATING. Falling within these two categories are the seven types listed in this section. Although the majority of actuator types are covered in the following pages, new developments may mean that the engineer is not fully aware of the operating characteristics of the device under scrutiny. If any doubt arises it would be preferred if the manufacturer were questioned prior to any checks or adjustments being carried out. An example of the above is the VAV actuator sensor controller. This is a type of actuator that has the controller built into the actuator housing. The sensor is connected via a length of cable and will commonly be sensing air velocity or pressure. The controller will have been set to the required VAV box demand and these settings should not be altered without prior consultation with the client, the VAV box manufacturer and the actuator manufacturer. In this example, cross-referencing should be made between the Actuators, Controllers and Sensors sections. Please refer to the overarching introduction (SFG 00-01) to make sure you are of the correct skill level as indicated within the task schedule to carry out the described works. Ensure you have read and understood the manufacturer’s recommendations, carried out risk assessment(s) on each item of plant to identify the correct frequency of maintenance, identified all safety procedures that need to be applied and recorded in order to carry out the work in a safe and reliable manner.

Schedule Title : Pre-Maintenance Procedures Schedule Ref : 01-02 Schedule Type : Core Schedule Date : 09 Nov 2012 Schedule Version : 1.0.0 Unit of Measure : Not specified Uncontrolled Copy - Printed: 30/11/2015 | Welplan SCHEDULE INTRODUCTIONS Should any discrepancies occur with the following checks the client should be informed as soon as possible to avoid the possible uneconomical running of his plant. The frequency of checks should be used as a minimum in the event that the actuator is performing a safety function (i.e. on a fire and smoke damper). Lives and property could depend upon this actuator working properly. 1. Cables. Check for signs of heat, damage, chafing or water ingress. 2. Mounting. Check mounting is in accordance with the manufacturer`s recommendation. 3. Anchor points. Check security. 4. Mechanical protection. Check for soundness. 5. Earth bonding. Check connection. 6. Actuator torque. Check torque with a torque wrench. This check is of particular importance on spring return type actuators because the spring will have a maximum life span. Elasticity of the spring and hence the torque will reduce with time, if the torque is insufficient to complete the action, this could be a hazard to life and property. 7. Working conditions. Check actuator is operating within its design ambient conditions. Please refer to the overarching introduction (SFG 00-01) to make sure you are of the correct skill level as indicated within the task schedule to carry out the described works. Ensure you have read and understood the manufacturer’s recommendations, carried out risk assessment(s) on each item of plant to identify the correct frequency of maintenance, identified all safety procedures that need to be applied and recorded in order to carry out the work in a safe and reliable manner.

Therefore should there be any loss in pressure, the performance of the actuator (and thus the whole system) will be impaired making it inefficient.

Ensure you have read and understood the manufacturer’s recommendations, carried out risk assessment(s) on each item of plant to identify the correct frequency of maintenance, identified all safety procedures that need to be applied and recorded in order to carry out the work in a safe and reliable manner.

Care should be taken to monitor the amount of operations left in the batteries and they should be replaced according to the manufacturer's instructions. The disposal of batteries calls for special arrangements, which should conform to all environmental and Health and Safety requirements. If the following actuators perform a safety function e.g. fitted to a fire/smoke damper, the frequency of checks should be taken as the maximum time between checks and reference should be made to the particular manufacturer's recommended frequencies. It should be remembered that people's lives and property could depend on the actuators functioning correctly.
