Teledyne 3000ZA-3X operating instructions ∙ 50-Pin Equipment Interface Port, Optional

Introduction 3000ZA-3X

∙Power Connection Universal AC power source.

∙Gas Inlet and Outlet One inlet (must be externally valved) and one exhaust out. Three inlets when option “C” is ordered.

∙9-PinRS-232 Port Serial digital concentration signal output and control input.

∙50-Pin Equipment Interface Port

Analog Outputs: 0–1 VDC oxygen concentration plus 0-1 VDC range ID

Alarm Connections: 2 concentration alarms and 1 system alarm.

Remote Valve: Used in the 3000ZA for controlling external solenoid valves only.

Remote Span/Zero: Digital inputs allow external control of analyzer calibration.

Calibration Contact: To notify external equipment that instrument is being calibrated and readings are not monitoring sample.

Range ID Contacts: Four separate, dedicated, range relay contacts. Low, Medium, High, Cal.

Network I/O: Serial digital communications for local network access. For future expansion. Not currently implemented.

Optional

∙Calibration Gas Ports: Separate fittings for zero, span, and sample gas input, internal valves for automatic gas switching.

∙Current Signal Output: Additional isolated 4–20 mA DC plus 4–20 mA DC range ID.

Note: If you require highly accurate Auto-Cal timing, use external Auto-Cal control where possible. The internal clock in the Model 3000ZA is accurate to 2-3 %. Accordingly, internally scheduled calibrations can vary 2-3 % per day.
