IS TO BE
NSTALLED AND
All power and signals must be de-energised before connecting any wiring, or altering any Jumpers or Dip Switches.
Mounting.
* Also refer to Connection Diagrams and Notes.
(1)
Mount in a clean environment in an electrical cabinet on 35mm symmetrical mounting rail.
(2)
Draft holes must have minimum free air space of 20mm. Foreign matter must not enter or block draft holes.
(3)
Do not subject to vibration or excess temperature or humidity variations.
(4)
Avoid mounting in cabinets with power control equipment.
(5)
To maintain compliance with the EMC Directives the 2100-R2 is to be mounted in a fully enclosed steel fire
cabinet. The cabinet must be properly earthed, with appropriate input / output entry points and cabling.
Cover Removal and Fitting.
To remove 2100 covers, firmly push down the button in the middle of one endplate, and pull the end plate outwards, while
pulling the cover up and out.
To fit the cover, first make sure the cover is being fitted the correct way around, (Terminal 82 on the cover is above 82
on the board.) and that the serial number on the board matches the serial number on the cover (if applicable). Slide one
end of the cover into the slot in the endplate. Pull the other endplate outwards and push the cover down until it slides into
the slot of this endplate. Check both ends are firmly held.
Power Supply Wiring.
(1)
A readily accessible disconnect device and a 1A, 250Vac overcurrent device, must be in the power supply wiring.
(2)
Any 2100-A connected to the 2100-R2, must share the same disconnect device and overcurrent device
(3)
For power supply, connect Phase (or +Ve) to terminal 82, Neutral (or -Ve) to 81, and Earth to 80. To ensure
compliance to CE Safety requirements, the grey terminal insulators must be fitted to ALL mains terminals after
wiring is completed. (ie. terminals 82, 81 and 80.) For Non Hazardous Voltage power supplies (not exceeding
42.4Vpeak or 60Vdc) terminals 81 and 80 may be linked together, instead of connecting an earth.
Analogue Signal Wiring.
(1)
All signal cables should be good quality overall screened INSTRUMENTATION CABLE with the screen earthed
at one end only.
(2)
Signal cables should be laid a minimum distance of 300mm from any power cables.
(3)
For 2 wire current loops, 2 wire voltage signals or 2 wire current signals, Austral Standard Cables B5102ES is
recommended. For 3 wire transmitters and RTDs Austral Standard Cables B5103ES is recommended.
(4)
It is recommended that you do not ground current loops and use power supplies with ungrounded outputs.
(5)
Lightning arrestors should be used when there is a danger from this source.
(6)
Refer to diagrams for connection information.
Commissioning.
(1)
Check that all the above conditions have been met, and the wiring checked, before applying power to the 2100-R2.
(2)
Check each relay output functions correctly, and the relay specifications are not being exceeded.
(3)
Check each digital input functions correctly, and the digital input specifications are not being exceeded.
2100-R2 Software Programming.
The 2100-R2 software setup is accessed via the attached 2100-A
Refer to the 2100-A
Installation Guide, and 'Programming 2100 Series Remote Station' in the Microscan Manual.
