Standby Button:
The Standby feature turns off the display and outputs, but circuitry is
still operating. It is useful for power saving as well as prolonging the life
of the display elements.
WARNING: THE INSTRUMENT IS STILL ENERGIZED WHEN THE
STANDBY BUTTON IS PRESSED.
THE POWER CABLE MUST BE UNPLUGGED TO
DISCONNECT POWER FROM THE INSTRUMENT.
WHEN CHASSIS IS EXPOSED OR WHEN ACCESS
DOOR IS OPEN AND POWER CABLE IS CONNECTED,
USE EXTRA CARE TO AVOID CONTACT WITH LIVE
ELECTRICAL CIRCUITS.
Access Door:
To provide access to the display circuitry, the PID temperature
controller or pressure compensation circuitry, the front panel swings open
when the latch in the upper right corner of the panel is pressed all the way
in with a narrow gauge tool. Accessing the main circuit board requires
unfastening the rear panel screws and sliding the unit out of the case.
1.3 Rear Panel (Equipment Interface)
The rear panel of the Model 3010MA Control Unit is shown in
Figure 1-2. Connections are made at this panel for power, RS-232
communication, equipment interfacing and connections to the Analysis
Unit. The connectors are described briefly here and in detail in the
Installation chapter of this manual.
• Power Connection— AC power source.
• Pressure In—1/8” Gas line input to pressure compensation
circuit from Analysis Unit.
 Line voltage—Selector switch for line voltage 115/230.
• RS-232 Port—Serial digital concentration signal output and
control input.
• Sensor In Connector—15 pin D-connector sensor cable from
Analysis Unit, (includes 24VDC power)
• Heater Out— 7 pin CPC connector, Power to heater in Analysis
