IDM T2 IDM T4 The IDM T4 DAU is an IDM T1 DAU enclosed in a carrying case for portable use. The IDM T4 DAU Upgraded IDM T2 DAU Access to the 10 analog and 16 event channels is via 4mm safety connectors accessible at the rear of the case.
IDM T6 LSU (Local Storage Unit) The IDM T6 DAU is an IDM T3 DAU enclosed in a carrying The LSU is a industrial PC based device that provides the case for portable use. following functions in an IDM installation: Non-volatile storage for DFR, TSS and CSS records Modem sharing between multiple DAUs Printing records from multiple DAUs...
Typical Installations In those installations where more than one IDM DAU is installed at a given location then they communicate with LAN/WAN each other using twisted pair or fibre-optic Ethernet. To interconnect devices using Ethernet a hub is required and some sample network topologies are shown below.
DFR Fault Recording CSS Continuous Slow Scan High speed recording, monitoring the transient response of the A slow scan function providing recorded calculated quantities for up to 15 days for long term power stability monitoring. This power system and equipment during and just after a system fault function requires a Local Storage Unit (LSU), an industrial PC or transient disturbance.
Harmonics Recording Function Power Quality Data Logging Function Sags and Swells - Power Quality Flicker Recording Function Sensor Flicker recording in compliance with the IEC 61000-4-15 standard is also provided with Pst and Plt values being provided. The power quality recording is equipped with a software power Flicker is calculated on a group of three phase voltage inputs quality sensor that automatically detects voltage sags (dips) and and the resulting data is stored in recorder memory.
Plus ™ Replay Plus Master Station suite of software applications provides configuration, communication, data analysis and management for a range of Qualitrol Hathaway Products. ™ Plus Master Station Software Replay When used with the IDM it provides the following functions.
System Layout It is very important to connect an earth to the main earth stud. This earth stud should be connected to the system substation A dimensioned picture of the 6U rack mounting IDM T3 DAU earth. is shown below. It is an easy device to mount. All analog, event and alarm signal conditioning is internal to the chassis.
This arrangement makes it easy to change a complete DAU without having to disconnect a large number of wires. An external DC wetting voltage is required to operate the digital inputs. This voltage is normally from the station battery. A DC voltage (in the correct range) applied across an input is interpreted as a closed contact while the absence of voltage is interpreted as an open...
The 10Base-FL connection is via the two ST fibre connectors RS232 (1) RS232 (2) and is used for longer range communication over fibre optic cables. Pin 1 Pin 1 Pin 2 Pin 2 The white coloured connector is for transmit and the grey colour for receive.
Clock Synchronisation The pin out for TB6 is given in the following table. The connections are via a screw terminal adapter block that plugs Each IDM DAU has an internal free running clock for time into TB6. stamping recorded data. This clock can be synchronized to an external source via a 1 pulse per second (1pps) applied on one Pin 1 A (loop in)
RS232 serial data to DAU Pin 5 Serial data grnd If the NGTS device is a Telefault GPS from Qualitrol Hathaway, then connection to COM1 on the Telefault GPS is made via Qualitrol Hathaway cable 16-2017 and its details are shown below. TX_D 3...
