FAULT RELAY—
Form C Type (NO/NC). Energized during Normal mode,
De-Energized on Fault or loss of power.
Contact Rating: 5 amperes at 30 Vdc.
Non-Latching Operation only — not programmable.
DIGITAL OUTPUT (Optional)—
Modbus digital communication.
CALIBRATION—
All units are factory set and calibrated to carbon dioxide.
Routine calibration of the Eclipse CO
2
detector after
completion of initial commissioning is supported, but
not absolutely required. Generally, an annual gas bump
test or full calibration will ensure proper sensitivity and
response.
NOTE
Frequent visual inspections of the detector are
recommended to confirm that there are no external
impediments to proper detection capability.
Four methods of initiating Calibration are supported:
–
On-Board magnetic reed switch
–
HART communication
–
Remote calibration line for remote switch
–
MODBUS communication
RESPONSE TIME (Det-Tronics Verified)—
T50 = 6 seconds.
VIBRATION—
PIRECL successfully passes Sinusoidal Vibration
Testing in accordance with MIL-STD-810C, Method
514.2, Paragraph 4.5.1.3, Figure 514.2-7 Curve AW, and
C22.2 No. 152-M1984, and also DET NORSKE VERITAS
Certification Notes – No. 2.4 dated May 1995.
ACCURACY (Det-Tronics Verified)—
0-20000 ppm or 0-2%/vol:
±10% Full Scale @ 25°C.
SELF-DIAGNOSTIC TEST—
Fail-Safe operation ensured by performing all critical
tests once per second.
INGRESS PROTECTION—
IP66/IP67 (DEMKO Verified).
DETECTOR HOUSING MATERIAL—
316 stainless steel (CF8M).
SURFACE PREPARATION—
Electropolish.
CONDUIT ENTRY OPTIONS—
Two entries, 3/4 inch NPT or M25.
HART COMMUNICATION PORT (Optional)—
Intrinsically Safe (I.S.). For live maintenance, follow
Control Drawing 011975-001 in Appendix H.
OPTICS PROTECTION—
The three-layer weather baffle assembly is UV-resistant,
static-dissipating black Polythalimide plastic. The
standard weather baffle version, recommended for most
outdoor and indoor applications, includes an internal
hydrophobic filter. The standard weather baffle includes
a 3/16” (4.8mm) barb fitting for attaching a 3/16” I.D.
hose during calibration.
Heated optics minimize condensation to ensure reliable
operation through temperature extremes.
WIRING TERMINALS—
Field wiring screw terminals are UL/CSA rated for up to
14 AWG wire, and are DIN/VDE rated for 2.5 mm
2
wire.
Screw terminal required torque range is 3.5–4.4 in.-lbs.
(0.4-0.5 N·m).
ELECTRICAL SAFETY CLASSIFICATION—
Installation Category (Overvoltage Category) II
& Pollution Degree 2 per ANSI/ISA-S82.02.01,
EN 61010-1 & IEC 61010-1.
