BH17 7ER WIG WAG SIGNALS Introduction Figure 85 Flashing Red Wig Wag Signals The Siemens Wig Wag system is a complete solution for the provision of priority signals at fire and ambulance stations The signals may also be used in other locations such as bridge crossings where there is a need to stop ordinary traffic flow but where it may be difficult for drivers to forecast when they will be required to stop In the UK the ST950LED and ST950ELV Traffic Controllers are approved to both TR2500A and TR2513A which allows them to be used at fire and ambulance stations and at bridges but not at rail crossings The controller can provide stand alone Wig Wag applications and also full intersections where Wig Wags are required nearby Both LV and ELV Wig Wag Signals utilise the latest generation of low power CLS LED signals The Siemens Wig Wag signals are compliant with TSRGD Diagram 3014 and conform to EN12368 Lamp monitoring is undertaken directly by the controller on both LV and ELV signals eliminating the need to fit lamp monitoring equipment within the Wig Wag signals ensuring power usage is kept to a minimum IMPORTANT As Wig Wag configurations are more complex to create than intersection configurations it is strongly recommended that they should only be created by Intersection Engineering at Siemens Poole Flexible activation Typically Wig Wags are activated by a button within the fire or ambulance station Where just simp

Base Time CLF System The non base time CLF system is a configurable alternative to the base time CLF system This system does not use a base time When a CLF plan is requested to start it starts at the beginning i e at time 0 of its CLF cycle Therefore the time that a plan is requested to start i e the time in the controller s timetable is critical to ensure that the CLF plan is synchronised with other controllers in the same area Also see section 28 6 Offset Times and Linked Installations Introduction to Offset Times The CLF facility allows a number of controllers in an area to be synchronised allowing the traffic flowing between them to move more freely Consider the following simple example The figures below show a simple linked installation covering three intersections on a main road into a city The CLF facility is used at the controllers at each of the three intersections A B and C Note that the plan start times are shown for a non base time CLF system option described in section 28 6 3 For all other ways of working as described in the rest of section 28 6 all the controllers will start running the plans at 08 30 00 and 16 15 00 Plan Start 08 30 35 08 30 20 08 30 00 a E CENTRE A 15 Secs B 20 Secs C EE Controller Timings gt 40 Secs lt 45 Secs lt gt 35 Secs 60 second cycle time 20 Secs 15 Secs 25 Secs Figure 64 Simple Linked Installation Morn
