SPECIFICATIONS
Series 2000 Control Unit
Display
Four-line x 20-character vacuum uorescent. Displays combinations of oxy-
gen, ppm combustibles, methane, time and date, cell temperature, user-pro-
grammable text, thermocouple mV or cell mV. Password protection, program-
mable pressure compensation and context-sensitive help are also provided.
Analog Output
Two isolated linear current outputs for oxygen and one each for combusti-
bles and methane if you purchased those options. Select O
2
, combustibles
(optional), methane (optional), cell temperature, thermocouple mV or cell
mV. Each output can be 4-20 mA, 0-20 mA, 20-4 mA or 20-0 mA and is
fully scalable. Hold or track during calibration and select degree of damp-
ing. Maximum load 1200 ohms.
Alarms
Two independent oxygen alarms, each high or low selectable. One alarm
can be allocated to % oxygen, calibrate or verify. Two high combustibles
and two high methane alarms (optional). Set relays to energize or de-
energize on alarm.
Contact Rating 1A, 30V max. noninductive load, AC or DC
Diagnostics
Watchdog timer and service alarms. System test for A/D, RAM, EEPROM
and keypad. Display Line 4 reserved for full text error and diagnostic mes-
sages. Twenty-entry event log.
Calibration
Oxygen cell lifetime extender. Calibrate or verify calibration. Store last
calibration and verication data. Selectable calibration gas run time and
process recovery time. Timed automatic calibration with optional remote
calibration unit.
Communications RS-485, 2-way addressable.
