3 Installation Model 2010A
3- Part I
3.3.1 Primary Input Power
The power cord receptacle and fuse block are located in the same as-
sembly. Insert the female plug end of the power cord into the power cord
receptacle.
DANGER: PowER Is APPlIED To THE INsTRUMENT's CIR-
CUITRy As loNG As THE INsTRUMENT Is CoN-
NECTED To THE PowER soURCE. THE RED I/o
swITCH oN THE fRoNT PANEl Is foR swITCH-
ING PowER oN oR off To THE DIsPlAys AND
oUTPUTs oNly.
NoTE: AC PowER MAy bE PREsENT oN THE RElAy
CoNTACTs wHEN THE PowER CoRD Is RE-
MovED!
The Control Unit is universal power 100-240V, 50-60 Hz. The Analy-
sis Unit requires 110 or 220 VAC and is selectable via switch located inside
the explosion-proof enclosure.
3.3.2 fuse Installation
The fuse block, at the right of the power cord receptacle, accepts US
or European size fuses. A jumper replaces the fuse in the neutral line when
the US size fuses are used. If the European size fuses are selected, both
sides at the line will be fused. Be sure to install the proper fuse as part of
installation. (See Fuse Replacement in chapter 5, maintenance .)
3.3.3 Analog outputs
There are four DC output signal connectors with spring terminals on
the panel. There are two wires per output with the polarity noted. See Fig-
ure 3-4. The outputs are:
0–1 V dc % of Range: Voltage rises linearly with increasing concentra-
tion, from 0 V at 0 concentration to 1 V at full
scale. (Full scale = 100% of programmable range.)
0–1 V dc Range ID: 0.25 V = Range 1, 0.5 V = Range 2, 0.75 V =
Range 3, 1 V = Cal Range.
4–20 mA dc % Range: Current rises linearly with concentration, from 4
mA at 0 concentration to 20 mA at full scale. (Full
scale = 100% of programmable range.)
4–20 mA dc Range ID: 8 mA = Range 1, 12 mA = Range 2, 16 mA =
Range 3, 20 mA = Range 4.
