Installation BDS 3960

3.3.2.1PRIMARY INPUT POWER

The power cord receptacle and fuse block are located in the same assembly. Insert 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 power supply requires 100–120 VAC, 50/60 Hz power source.

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 may not be installed at the factory. Be sure to install the proper fuse as part of installation. (See Fuse Replacement in Chapter 5, Maintenance.)

3.3.2.250-PIN EQUIPMENT INTERFACE CONNECTOR

Figure 3-4 shows the pin layout of the Equipment Interface connector. The arrangement is shown as seen when the viewer faces the rear panel of the analyzer. The pin numbers for each input/output function are given where each function is described in the paragraphs below.

Analog Outputs: There are four DC output signal pins—two pins per output. For polarity, see Table 3-1. The outputs are:

0–1 VDC % of Range:	Voltage rises linearly with increasing
	oxygen, from 0 V at 0 ppm to 1 V at
	full scale ppm. (Full scale = 100% of
	programmable range.)
0–1 VDC Range ID:	0.25 V = Low Range, 0.5 V = Medium
	Range, 0.75 V = High Range, 1 V =
	100ppm.
