Total E-STOP for additional safety
The RE-B3 serves as an independent safety measure that can immediately pause or disable a laser system that’s possibly entering a dangerous or damaging situation. What’s more, it can be triggered locally or via the operators controller, further compounding the safety advantages of the RE-B3. This means the moment a problem is noticed in any instances the lasers can be stopped immediately.
The RE-B3 local unit has two levels of E-Stop a 50% kill which will activate the open condition on the interlock input and a 100% kill which will kill total power to the system. The 50% kill is a CATEGORY 2 which is not classed as an E-Stop but is built into the laser systems by manufactures. The 100% kill is a CATEGORY 0 which is the highest level of E-Stop and will stop everything connected to it. Both of the E-Stops are switched via independent relays which are rated at 277VAC @ 20A & 30VDC @ 20A.
The inclusion of XLR and Powercon connections on the RE-B3 adds more stability and a local point of E-Stop (on the front of the 19” unit) if the need arises for the operation of the E-Stop system. The E-Stop on the front when operated will kill both the 50% XLR interlock and the 100% power output.
Power to the RE-B3 is fed via a Neutrik Type A Power Connector on the front which in turn feeds the power out via Neutrik Type B Power Connectors which is switched. This power is now under the control of the 100% kill E-Stop button and can be killed instantly upon any arisen emergency.
The type of power connectors varies from country to country so we can supply the cables unterminated for the end user to fix the appropriate power connector relevant to their country.
ISO 13850 limits the selection of E-Stop categories to Category 0 or 1 and excludes Category 2. Category 2 may only be used for operational or “normal” stopping functions.
