1 AB Axis Industries PULSE ADAPTER ENCO PULSE The ENCO PULSE pulse adapter acquires and handles the pulses from consumption meters with pulse output and transmits the data to a network of AMR system. Use The pulse adapter is a component of the AMR system. It is used when data of pulse output meters shall be collected by AMR system. Such devices can be meters for hot water, cold water, gas, electricity, etc. Functions Acquisition of the pulses delivered by the connected consumption meters AB Axis Industries Pulse adapter PA-1 1 (5)

2 Monitoring the connecting cable in the case of metering devices with NAMUR circuit Handling of pulses and storage of consumption data and set day values Transmission of data telegrams to the AMR system Ordering ENCO PULSE-MBus - Pulse adapter with integrated M-bus interface (Standard version). ENCO PULSE-RS - Pulse adapter with integrated 3V RxTx interface (special order). ENCO PULSE-RF - Pulse adapter with integrated RF 866MHz interface (special order). Technical data The pulse adapter handles only pulses from potential-free pulse sources, according with the following specification (depending on the programmed pulse source type): Pulse source Limit values (if parameters are appropriately set) Electronic outputs residual voltage when switched <0,7V (Open Collector, max. frequency <16Hz Open Drain) min. pulse width 30ms Mechanical bounce time <1ms switches max. frequency <2Hz min. pulse width 260ms Mechanical bounce time <1ms switches with max. frequency <2Hz NAMUR circuits min. pulse width 260ms Resistance R1 2,2 kώ Resistance R2 5,6 kώ Length of Total length of the connecting cable may not exceed 10 m. connecting cable Power supply Data transmission The pulse adapter is powered by a lithium battery 3,6V, which has a service life of years. During the replacement of the battery, the adapter must be connected to the communication network. Data are transmitted inside M-Bus network (or3v RxTx network) to the central unit on demand AB Axis Industries Pulse adapter PA-1 2 (5)

LST EN :2004/P:2007 Safety class III by EN60950 Degree of protection IP65 by EN Ambient temperature: Operation ºC Transport and storage ºC Weight not more 0,3 kg Mounting Pulse adapter can be mounted on standard DIN-rail, in electrical cabinet or on vertical wall, using three screws. It must be installed at the nearest possible distance from the meters. It is forbidden to wire pulse cable and network cable nearby (less than 5 cm) with power cables or cables of other devices. Important: It is forbidden to attach the pulse adapter directly to a wall if there is a risk that on walls can be condensed humidity or temperature of a surface of a wall can fall lower than 5. In this case, it is recommended to attach the calculator so that between it and wall surfaces there were an air gap not less than 5 cm. Mounting on the wall: Mounting on standard DIN-rail in electrical cabinet: AB Axis Industries Pulse adapter PA-1 3 (5)

4 Turn down the fixers and remove the cover. According to the connection diagram connect up the adapter to the meter and to the communications network. Two-wire cable with cross-section 0,14 0,25 mm 2 should be used for connection. Cables should be run through rubber seal caps and anchored with clamps. Commissioning notes The pulse adapter must be programmed during installation. Only properly trained service personnel can set up the parameters of pulse adapter. The parameters can be set via M-bus (or 3V RxTx), using a PC with special software.
