71Mounting- and Operating Instruction CEAG DualGuard-S 40071860347 January 2020 www.ceag.de33 3-PM Module33 3-PM ModuleIn order to avoid the risk of power failures, it is necessaryto permanently monitor the function of the general lightinglight distributors in order to switch on the safety lighting inthe event of a fault. The CEAG 3-PM modules are thereforean important part of the safety system.If one phase fails, the CEAG 3-PM module switches arelay contact and interrupts the 24 V current loop (ACU DGterminals IN 1 to IN 8) to the emergency lighting units. Allemergency lights in standby mode are switched to conti-nuous light. A second relay contact (change-over contact1,2,3) is used to signal the mains failure. E30 wiring of the24V current loop is not required for installation across firecompartments, as the emergency lighting is automaticallyswitched on in the event of a first fault in the 24V currentloop of a suitably designed system in the event of an inter-ruption or short circuit.The easily accessible test button offers the advantage thatan interruption of the mains voltage is not necessary tocheck the function of the voltage monitoring devices. As arule, one of the monitored phases must be enabled withouta test button, which at least leads to a failure of the powersupply of the general lighting and thus to severe disturban-ces of the operational processes.Ordering detailsType Description Order No.3-PM Module Phase monitor module for DIN rail mounting 40071361660Technical descriptionDimensions LxHxT: 85x52x64 mmWeight: 0,07 kgAssembly: Vertikal auf DIN-SchieneDegree of protection: IP20Protection class: ?Ambient temperature: -5°C…+55°CStorage temperature: -20°C…+65°CRelative humidity: 10…95%, no condensationElectromagnetic compatibility: Industry EN 61000-6-2, Commercial EN 61000-6-3Degree of pollution: 2Overvoltage category: III for MainsRated voltage: 264V220…240V ACPower consumption: 2 WRelay output:Switching voltage: ≤ 30 V DC/AC SELVRated current: ≤ 0,5AMax.
