Teledyne 3000ZA-3X operating instructions Equipment Interface Connector Pin Arrangement

Installation 3000ZA-3X

CAUTION: POWER IS APPLIED TO THE INSTRUMENT'S CIRCUITRY AS LONG AS THE INSTRUMENT IS CONNECTED TO THE POWER SOURCE. THE RED SWITCH ON THE FRONT PANEL IS FOR SWITCHING POWER ON OR OFF TO THE DISPLAYS AND OUTPUTS ONLY.

The universal power supply requires an 85–250 VAC, 47-63 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 are not 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: 0.20 V = Low Range, 0.5 V = Medium Range, 0.80 V = High Range.
