3 Installation Model 3010 PA
3-4: Part I
Primary Input Power: The universal power supply requires a 85–250
V ac, 47-63 Hz power source. The power cord receptacle and fuse block are
located in the same assembly. Insert the female plug end of the power cord
into the power cord receptacle.
CAUTION: Power is applied to the instrument's circuitry as
long as the instrument is connected to the power
source. The red
I/O switch on the front panel is for
switching power on or off to the displays and out-
puts only.
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
whichever fuse receptacle is not used. Fuses are not installed at the factory.
Be sure to install the proper fuse as part of installation. (See Fuse Replace-
ment in chapter 5, maintenance.)
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 Figure 3-5. The outputs are:
0–1 V dc % of Range: Voltage rises linearly with increasing oxygen, from
0 V at 0 % to 1 V at full scale. (Full scale = 100%
of programmed range.)
0–1 V dc Range ID: 0.25 V = Low Range, 0.5 V = Medium Range,
0.75 V = High Range, 1 V = Air Cal Range.
4–20 mA dc % Range: (Optional) Current increases linearly with increasing
oxygen, from 4 mA at 0 % to 20 mA at full scale.
(Full scale = 100% of programmed range.)
4–20 mA dc Range ID: (Optional) 8 mA = Low Range, 12 mA = Medium
Range, 16 mA = High Range, 20 mA = Air Cal.
