Description

The E05 Line Isolation and Overload Monitor in conjunction with the E14 SeriesIsolation Transformer, forms the basis of an isolated supply system whichprovides electrocution and overload protection as detailed in AS/NZS 3003‘Electrical Installations – Patient treatment areas of hospitals and medical anddental practices.’

An isolated supply is a continuous supply. The isolation transformer isolates thepower from earth therefore a fault on both lines of the secondary transformerwinding needs to occur before a fault current flows. A fault on only one line andearth will not cause a fault current to flow.

The E05 Line Isolation and Overload Monitor (LIOM) enables the integrity of anisolated power supply system to be continuously monitored. The LIOM is able todetect when one fault occurs therefore is able to warn of a potentially hazardoussituation before any fault actually flows. The first fault is known asProspective Hazard Current (PHC). The LIOM dislays the PHC on an LCDbargraph display and when 5 mA PHC is reached a mutable alarm sounds alongwith a flashing LED indicator labelled ‘PHC Warning.’

If a PHC alarm condition arises, the medical staff can, in light of theseriousness of the patient’s condition, choose to continue with the procedure. Inthis situation, the surgeon is relying on a second fault not occurring that wouldturn the PHC into a real flow of current. During this time measures can be takento rectify the fault condition by, for example, disconnecting all non-essentialequipment.

In addition to the LIOM’s monitoring isolation, it also warns of impendingoverload, thus averting problems which could result from a loss of supply. Whenthe overload level is reached a mutable alarm sounds along with a ‘OverloadWarning’ flashing LED indicator.

CONTACTS

The E05 must be installed by a qualified electrician in accordance with thedetailed instructions here and the requirements of AS/NZS 3003 &AS/NZS 3000.

Connect the E05 and associated electrical components as per the wiringdiagram, making sure to take into consideration the following installation guidelines.

• Long runs of cable between the transformer and the LIOM and/or long runs between the LIOM and the outlets should be avoided. Due to capacitive coupling between cables and between cables and conduit, runs longer than 50m can result in high standing PHC (ie, >2 mA).

• Parallel runs of cables from two or more isolated supplies should also be avoided. The ‘crosstalk’ between parallel cable may cause rhythmic fluctuations on the units’ displays. Where parallel wiring cannot be avoided, wiring should include an earth (eg, TPS). The earth conductor should be earthed only at one end of its run. While running cable in this manner will lessen crosstalk problems, it may increase standing PHC.

• Due to the LIOM’s monitoring the load current ‘on line’ the LIOM must be the first item connected to the secondary winding of the isolation transformer. All items to be powered from the isolated supply must connect back to the terminals of the LIOM labelled ‘Active 1 Out’ and ‘Active 2 Out.’ Failure to do this will result in incorrect measurements of the load current.

• In some installations there might be a high inrush current when power is first applied to the isolation transformer therefore a suitable circuit breaker needs to be chosen. It is recommended to use a Heinemann Electric CF series circuit breaker.

Operating Instructions

1. Check power is connected to the E05 LIOM by confirming the power indicator is on, which is located at the bottom of the LCD bargraph display.

2. Monitor the level of Prospective Hazard Current (PHC) using the LCD bargraph display. A correctly functioning system should display little or no PHC. When a PHC of at least 5 mA is detected the E05 will alarm both audibly and visually (PHC Warning Indicator) but the supply will not be interrupted. When this alarm condition arises the surgeon can, in light of the seriousness of the patient’s condition, choose to continue with the procedure. In this situation the surgeon is relying on a second fault not occurring that would turn the PHC into a real current flow. During this time measures can be taken to rectify the fault condition by, for example, disconnecting all non-essential equipment.

3. Monitor when the load current rating of the isolation transformer has been exceeded by monitoring the Overload Warning indicator. When the E05 detects that the load current rating has been exceeded the E05 will alarm both audibly and visually (Overload Warning indicator).

4. If required to mute the audible alarm then press the Mute button. The PHC Warning indicator or Overload Warning indicator will remain on until the fault is removed.

5. Test the PHC monitoring function of the unit by pressing the Test button. In the test mode the E05 should display approximately 7.5 mA PHC on the LCD bargraph display. The E05 should also go into Audible Alarm, and the PHC Warning indicator should turn on.
