(glow) is detected with high sensitivity and fast response time. AFT arc detectors cannot avoid arcing, but they are designed to effectively limit the energy of the arc by ultra-fast light detection and by providing a fast interlock signal to shut-down the RF source.
Page 8 (AND/OR). These signals are available as TTL or O.C. With two SIMs one ARC4 system is capable of forming a total of four arc interlock signals (A, B, C, D) and thus to interlock up to four separate RF systems. The default logic for all GLBARCs is an OR combination of all 16 arc channels.

Page 17: Installation And Initial Start
8. Installation and Initial Start  Place the device in its intended position - the ARC4 2.0 can be used as a desktop device or installed in a 19" cabinet. Maintain environmental temperature and humidity conditions as specified in the data sheet.
Page 18: Safety Notes For Operation Of The Device
 ARC4 2.0 can only deploy its full capability of fast arc detection, if the arc viewport (observation point) is spot most close to a critical location. Even though in many cases the high light sensitivity allows the coverage of more than just a single spot, we always recommend to provide a separate arc viewport for each critical area.
Page 19: Test Functions
Manual ARC4 2.0 Test Functions The ARC4 2.0 allows the user to test proper function of light detection by two means – internal and external test. 10.1. Test Internal The internal test checks the proper function of detector itself and related electronics in all installed arc detector modules by introducing a short IR pulse from an internal IR LED through an additional bore directly into the detector input.
Page 20: Test External
10.3. Optical Test Module Multiple ARC4 Optical Test Modules (OTM) can be installed in any available slot for arc detector modules, that is slots 1-16, best starting from slot 16 and moving down. E.g., if two OTMs are to be installed, they should occupy slots 16 and 15.
Page 21: Info-Menu
Manual ARC4 2.0 The optional ARC4 Optical Test Module 2.0 is designed for precisely testing the functionality of up to two arc detector modules at a time along with connecting additional fiber optic cables. It enables the user to verify the full optical loop path of detection, from the arc viewport to the detector input. In this case the arc viewport has to be equipped with an additional FSMA test port, in such a way that the test port sends light into the arc viewport.

Page 27: Basics Of Glbarc Logic
Note 12.3. Basics of GLBARC Logic Basically, ARC4 2.0 system interface modules offers two combinational logic schemes for a GLBARC group (A, B, C, D): an OR combination of selected arc channels and a pairwise AND combination of arc channels. Each GLBARC group can be programmed and used independently from each other.

Page 29: Maintenance, Storage And Modular Upgrade
Regard 13.3. Modular System Upgrade ARC4 2.0 can be upgraded with additional arc detector modules (ADM), optical test modules (OTM) and system interface modules (SIM) up to the max. number of card slots. ADMs and OTMs use card slots 1 to 16. The SIM models SIM-00 and SIM-01 use the dedicated slots 17 and 18 only.
