5 Maintenance		Model 5000B Photometric Analyzer

WARNING: DANGEROUS HIGH VOLTAGES ARE PRESENT AT THESE TERMINALS. TRAINED PERSONNEL MUST REMOVE THE SILKSCREEN COVER ONLY. EXER- CISE EXTREME CAUTION.

The first strip terminal has three contacts labeled N, G and H. The labels stand for Neutral, Ground, and Hot. This is the AC power strip terminal. It feeds AC power to other components of the Model 6000B System, such as the D2 lamp power supply, heater, and temperature controller PCB.

The second strip terminal has four contacts labeled SHLD, SIG, GND, MEAS and REF. This strip terminals are dedicated to the signals coming from the photodetector amplifier. The labels stand for:

SHLD:Shield. Shield form the preamplifier cable connects to this contact.

SIG GND: Signal Ground. Ground reference for both the measure and the reference signal.

MEAS: Measure Signal voltage.

REF: ReferenceSignalvoltage.

The third terminal strip has eight contacts labeled -230 VDC, +15 VDC, -15 VDC, COM, SPAN FLTR, SPAN SOL, ZERO FLTR, ZERO SOL. This strip feeds the high voltage needed on the cathode of the photodetector, DC power for the photodetector preamplifier, and control signals for the sole- noids and filters. The labels stand for:

-230 VDC: This is the negative high voltage fed to the photodetector cathode, about -230 VDC.
