Teledyne 3000PA operating instructions RS-232 Port, Remote Probe, Network, Optional

1 Introduction Model 3000PA

•Alarm Connections 2 concentration alarms and 1 system alarm.

•	RS-232 Port	Serial digital concentration signal output
		and control input.
•	Remote Probe	Used in the 3000PA for controlling
		external solenoid valves only.

•Remote Span/Zero Digital inputs allow external control of analyzer calibration. (See Note, below.)

•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	For future expansion. Not implemented
	at this printing.
Optional:

•Calibration Gas Ports Separate fittings for zero, span and sample gas input, and internal valves for automatically switching the gases.

•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 3000PA is accurate to 2-3 %. Accordingly, internally scheduled calibrations can vary 2-3 % per day.
