A sar-up override can be iniiaed via inpu II. The duraion o he sar-up override can be seleced beween 5 and 20 seconds by means o a bridge (saring rigger) or an exernal rigger signal.

4 Sandsill monior wih roaion direcion monioring (S3 = II) The device also oers sand sill monioring wih direcion o roaion monioring as an alernaive o sand sill monioring wih sar-up override. The rip values are idenical o he sandsill monior wih sar-up override. A inpu II a signal ha is ose by 90 o inpu I has o be applied; in his conex minimum signal overlapping should be ensured. Signal ransmiers a inpu I and inpu II can be sensors in accordance wih DIN EN () or conacs. Boh inpus are moniored or lead auls. Oupu I is used or sandsill signalling and swiches o a de-energised sae () in he even o a sandsill. Oupu II is swiched o acive when he direcion o roaion is clockwise. I a reverse roaion is deeced or i a signal overlap is missing, oupu II swiches o a de-energised sae (). In his case i can be concluded, ha he sensor is misadjused or deecive. I he sensor a inpu I is misadjused or deecive, inpu II is used or sandsill monioring.

Advice on use in SIL2 applicaions (Funcional saey) Care should be aken o ensure ha he relays are de-energised () in he criical condiion o he applicaion. Then, in he even o a power ailure (de-energised, relay) he saey-criical sae (energised) relay canno be achieved. Example 1: The proecive guard or a roaing sha mus remain locked in posiion unil he sha has sopped roaing. The saey-criical condiion is he roaion o he sha (risk o injury).for his reason, he locking o he proecive guard should be achieved by means o a de-energised () relay. The relay shall be energised (acive) only when he sha has sopped (sae condiion). This device uncion is only achieved wih "Sandsill monioring wih sar-up override" (S3 = I) and conrol o he proecive guard wih relay 2. Example 2: The cooling o a criical process by means o ans/coolan pumps has o be moniored. The saey-criical condiion is he sandsill o he ans/pumps (overheaing). For his reason an alarm mus be riggered when a relay has de-energised (). As long as he ans or he pumps are running (saey condiion) he relay is energised (acive). This device uncion can be achieved wih "Sandsill monioring wih sar-up override" (S3 = I) and "Sandsill monioring wih direcion o roaion signalling" (S3 = II) wih relay 1. 4

I no Power Rails are used, power supply o he individual devices is possible direcly via heir device erminals. Each power eed module is used or using and monioring groups wih up o 100 individual devices. The Power Rail PR-03 is an inse componen or he DIN rail. The Power Rail UPR-03 is a complee uni consising o he elecrical inse and an aluminium proile rail 35 mm x 15 mm x 2000 mm. To make elecrical conac, he devices are simply engaged.
