All power and signals must be de-energised before connecting any wiring, or altering any Jumpers or Dip Switches.
Do not start the Microscan before programming in a unique station number. Refer ‘Station Number Programming and
Serial Number’.
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-D 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)
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.
RS422/485 Comms Signal Cabling.
(1)
Use only low capacitance, twisted pair, overall screened data cable. The cable must equal or better the following
specifications.
NOTE:
All cables are to be subject during manufacture to in-process spark testing @ 4kVrms.
All cables are to be tested between conductors and conductors to screen for 1min @ 1500Vrms.
(2)
Minimum cable pairs:
RS422 = 2. (Plus overall screen.)
RS485 = 1. (Plus overall screen.)
(3)
Take care not to stress or damage cables during installation.
(4)
Total length of trunk line, including spurs, is not to exceed 1200m without isolating boosters.
(5)
Terminating resistors -1k
Ω
.
(6)
Cabling paths should avoid sources of radio frequency interferences such as fluorescent lights, variable speed
motor drives, welding equipment, radio transmitters, etc.
(7)
There should be a minimum of 200mm physical separation between power cables and data cables.
(8)
Data cables should not be exposed to excessive heat or moisture, and should not be buried directly in the ground
without protection.
(9)
Avoid powering a remote station or controller from the same power supply as a variable speed drive.
(10)
All unused twisted pairs should be terminated at both ends with 1k
Ω
resistors. DO NOT ground unused pairs.
