Installation

Teledyne Analytical Instruments 29

3.3.3.1 PRIMARY 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 standard power supply requires 110 VAC, 50/60 Hz or 220

VAC, 50/60 Hz (optional) power.

3.3.3.2 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 whichever fuse

receptacle is not used.

3.3.3.3 50-PIN EQUIPMENT INTERFACE CONNECTOR

Figure 3-2 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.

3.3.3.4

ANALOG OUTPUT

There are four DC output signal pins—two pins per output. For

polarity, see Table 3-1. The outputs are 0-1 VDC, 0-1 VDC, 4-20mA

DC, and 4-20mA DC.

The first and 3

outputs (0-1 VDC, and 4-20mA DC) operate

analogously as do the 2

and 4

outputs (0-1 VDC, and 4-20mA DC).

Each pair (1

and 3

), (2

and 4

) of outputs may be sourced to 1

of 4 possible measurements:

% of Range for CH4.

% of Range for NMH.
