Teledyne Analytical Instruments
3 Installation Model 2010B
3-4 Part I
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 receptacles accepts European size fuses only (5x20mm). Both
sides of the line are fused. 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 installa-
tion. (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 Figure 3-
4. The outputs are:
0–1 V dc % of Range: Voltage rises linearly with increasing concentration,
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.
