SERIES 2000 CONTROL UNIT

Display: Four-line x 20-character vacuum
fluorescent. Displays combinations of
oxygen, time and date, cell temperature,
user programmable text, thermocouple
mV or cell mV. Password protection,
programmable pressure compensation and
context-sensitive help are also provided.
Analog Output: Two isolated linear current
outputs. Select O2, 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
damping. Maximum load 1200 ohms.
Alarms: Two independent oxygen alarms,
each high or low selectable. One alarm
can be assigned as oxygen, calibrate
or verify. Set relays to energize or deenergize on alarm.
Contact Rating: 0.5 A, 30V, 10 VA 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
messages. Twenty-entry event log.

(General Purpose) wall mount, GP 19” rack
mount, GP panel mount, or stainless steel
weatherproof NEMA 4X (IP 56) wall/panel
mount. All are UL Listed for NEC Class I,
Division 2 areas. Purged and explosionproof versions also available.
Calibration: Oxygen cell lifetime extender.
Calibrate or verify calibration. Store last
calibration and verification data. Selectable
calibration gas run time and process
recovery time. Timed automatic calibration

EXCESS FUEL OPTION
Extends operating range of analyzer
from excess oxygen only to include
substoichiometric conditions (excess
fuel). Allows two-point calibration in
excess fuel range. Measure, display, and
provide alarms and analog outputs as
follows:
t
Display Options: Excess fuel,
combustibles, oxides/ fuel, fuel/
oxides, combined excess oxygen/
excess fuel (combustibles)
t
Display Range: 0-50% excess fuel
t
Output Range: 0-1% to 0-50% excess
fuel
t
Alarms: Standard alarms can be used
for high or low excess fuel levels
