    Relay MCR for the main contactor and Relay CBR for the circuit breaker. Relay RL3 is not used in the 11kV IPD. Relay RL4 when closed applies 110V to the HV Test Module for the Insulation Test.

  • Page 9: Remote Display Module

    This remains the case even if a power down occurs following a trip condition. 3.2 Remote Display Module This module (Ampcontrol RDM-D) consists of a two line - 16 character LCD display, LED status indicators and a tactile keypad.

  • Page 10: Trip / Status Messages

    Issue: R4, Date: 10/2011, CRN: 8874 The IPD status display is one of the most useful features of the relay’s display system and should be viewed as the first step in fault finding. The Status display is the default screen on power up and indicates what the IPD Relay requires in order to allow the outlet to close.

  • Page 12: Last Trip Status Messages

    Last Trip Status Messages: The IPD Relay has several functions which can stop/trip the outlet and then self-clear. The IPD Relay therefore saves the non-latched trip codes in a register and displays the ‘Last Trip’ messages in the Status Message Page.

  • Page 13: Machine Communication

    (See RTU-D General Case Dimensions on Drawing IPD-A-015) The Remote Termination Unit (RTU-D) provides remote stop, start facilities of the IPD Relay’s controlled outlet. The circuitry involved for these functions are self-diagnostic and will cause the outlet to turn off if the circuits are earthed or interconnected.

  • Page 14: Machine Type Codes

    There are 26 selectable machine type codes available for use in the Remote Termination Unit. The descriptive code is transmitted to the IPD Relay to identify the type of machine connected to the outlet. The codes are selected using the Remote Display Module (Level 9, Position 1).

    The time delay is adjustable. Range: Instantaneous (<50mS) 100mS, then 150 to 470mS in 40mS increments. The IPD generates a CT Detection Signal continuously to test the integrity of earth leakage circuit. The CT Detection signal continually tests the toroidal current transformer, the wiring loop to the toroid and the input to the protection relay, as required by AS/NZS 2081.3 - 2002.

    Module 11kV to perform high voltage line insulation tests. The HV Test Module 11kV must be used when the ‘Insulation Test’ function is required. When EFLO-11kV None is selected the IPD Relay does not provide an EFLO or a HV Test’, or any of the voltage functions, including under voltage checking.

    Remote Termination Unit is used to achieve machine communication. The IPD relay can be configured to operate in either diode or RTU mode. The mode is selected in “Pilot Type”, (Level 8, Position 1) and determines what terminating device the relay is looking for on the pilot.

    Level 5 and the Status Page (Level 0, Position 0). Following a trip condition the following conditions must be met to achieve a reset: (a) The IPD reset input must be closed (b) The trip accumulator must be less than 80% 6.2 Over-current Characteristics...

  • Page 21: Motor Overload Characteristic

    The motor manufacturer’s data should be consulted to select the time multiplier appropriate for the motor being protected. Typically, the capacity of a cold motor is given at six times its rated current. The IPD trip curves can be used to select the time multiplier, which best suits the motors overload capacity.

  • Page 22: Short Circuit

    Issue: R4, Date: 10/2011, CRN: 8874 When a trip occurs the IPD Relay cannot be reset, by operation of the reset button, until the accumulator is less than 80%. To allow an emergency restart on a hot motor to be achieved a reset of the thermal memory is possible by selecting Level 5, Position 3 on the Remote Display Module.

    A main contactor fail trip causes the CBR relay to de-energise, which trips the circuit breaker. An internal battery backed flag in the IPD Relay is also tripped. A LED on the front panel of the IPD Relay begins to flash.

    Interlock Drive (FID) processor output. The status of the input/output can be viewed on the Remote Display Module - “Relay and Digital Input Status” Section (Level 6, Position 4). The outlet control in each IPD Relay has been designed so that an outlet will not run unless either: (a) The FIR input is “ON”, or (b) The Remote Termination Unit connected to that IPD has been programmed with machine type “iFan”.

  • Page 25: Interlocking Sequence

    8.2 Interlocking Sequence The fan interlocking operates as follows: 1. Each IPD powers up with the FID output turned off. At this point the FIR input on all IPD Relays will read, as off, therefore no outlet will run. 2. When a machine is plugged into an outlet that has its Remote Termination Unit programmed “iFan” then that relay will be allowed to run when requested.
  • Page 26 The second group of settings consists of parameters that are related to the load connected to the protected outlet. These settings are stored, retrieved to/from the memory in the IPD Relay or the memory in the Remote Termination Unit, depending on the “Pilot Mode” setting. Figure 9.1 shows how the memory is “switched”. If a diode pilot mode is selected the IPD Relay reads and writes to and from the relay’s internal memory for the group 2 settings.

    10.2 Output Relays The IPD Relay has output relays to control the main contactor (MCR) and the circuit breaker (CBR). Both relays are fail safe with respect to power supply loss and are controlled on the basis of protection functions.

  • Page 29: Rtu Mode

    Once these conditions are obtained a cable fault lock out test is performed automatically, followed by a HV insulation test (if enabled). This takes 3 seconds. If the results of these tests are satisfactory, the IPD Relay goes into the run mode and the MCR relay picks up.

  • Page 30: Event Log

    11 Event Log A real time clock/calendar is included in the IPD Relay. This combines with the non-volatile memory to provide a data-logging feature. This log sequentially records the time, date and details of the most recent event. A chronological list of the previous 120 events is stored.

  • Page 32: Remote Data Communications

    13 Remote Data Communications The IPD Integrated Protection Relay has the facility for connecting remote monitoring equipment. This can be in the form of either the Remote Display Module or other peripheral equipment such as PLC’s. For PLC applications each integrated protection relay is connected to a Serial Interface Module (IPSI-D), which has its output drop connected to a DNET-IP2 Protocol Converter.

  • Page 33: Installation

    Connections to the IPD Relay are made via a plug in base. This base is to be securely fastened to the enclosure in which it is being installed. The base is clearly labelled for ease of terminal location and identification. The base sockets are factory adjusted so that they are able to move to assist in alignment when the relay is inserted.

    Earthing The IPD must be infallibly connected to the main system earth via the three earth terminals provided on pins 2, 7 and 12. To maintain the intrinsically safe properties of the relay it is vital that the earth pins 2, 7 and 12 are all individually connected with a minimum earth conductor size of 1.5mm2.

  • Page 36: Low Voltage Signals

    14.2.4 High Voltage Circuits The “high” voltage circuits of the IPD Relay are the 110VAC supply (pins 30, 31) and the relay contacts. Apart from keeping these separate from the other wiring to the relay there are no special requirements.

    If a problem is experienced with the relay, use the following tables to fault find the problem. Should the fault persist, remove the relay and return the relay, plus a description of the fault, to Ampcontrol for repairs. Checking the Status page (level 0, position 0) should be the first step in troubleshooting.
