Teledyne 6600 manual 1.5Control Section Interface Panel, Introduction, Model, • Analog Outputs

1 Introduction Model 6600

Alphanumeric Interface Screen: The backlit VFD screen is an easy- to-use interface between operator and analyzer. It displays values, options, and messages for immediate feedback to the operator.

1.5Control Section Interface Panel

The Control Section interface panel, shown in Figure 1-2, contains the electrical terminal blocks for external inputs and outputs. The input/output functions are described briefly here and in detail in the Installation chapter of this manual.

•Power Connection AC power source, 115VAC, 50/60 Hz

• Analog Outputs	0-1 V dc concentration and 0-1 V dc
	range ID. Isolated 4-20 mA dc and 4-20
	mA dc range ID.

•Alarm Connections 2 concentration alarms and 1 system alarm.

•	RS-232 Port	Serial digital concentration signal output
		and control input.
•	Remote Bench	Provides all electrical interconnect to the
		Analysis Section.
	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.

• Network I/O	Serial digital communications for local
	network access. For future expansion.
	Not implemented at this printing.

Note: If you require highly accurate Auto-Cal timing, use external Auto-Cal control where possible. The internal clock in the Model 6600 is accurate to 2-3 %. Accordingly, internally sched- uled calibrations can vary 2-3 % per day.
