GENERAL
DESCRIPTION
The C7061A1020 and C7061F1003 detector models are
identical except for housings.
Model C7061F1003 detector is for use in installations
requiring explosion-proof packaging. The housing is
conforming the EExd IIC T6 classification. More details
for the explosion proof housing can be found in the
chapter Standards and Approvals.
The C7061F1003 model has a 1-inch NPT tapping for
mounting onto a sight pipe. For allowable mounting
positions of model C7061A1020 and model C7061F1003,
see Page 9.
FEATURES
•
Oscillating shutter interrupts ultraviolet radiation
reaching the UV Sensor 12 times per minute (when
used with R7861 amplifier in combination with 7800
SERIES) to provide the UV Sensor tube checking
function. Amplifier circuitry components are checked
from the microprocessor in the 7800 SERIES Control.
•
Detectors can be mounted horizontally, vertically or at
any angle in between. The self-checking C7061 models
require faceplate alignment and have integral locating
reference points to assure proper operation of the shut-
ter mechanism.
•
Ultraviolet radiation sensing tube and quartz viewing
window are field replaceable.
The terminal block on both models is of wire clamp type
with removable screws and is situated in the compartment
of the C7061. The UV cell contains an ultraviolet sensing
tube, shutter assembly, terminal block and magnifying
lens.
The UV sensor can be mounted from the flame safeguard
device up to an average length of ca. 30m. This also
depends on the flame signal strength that is measured on
the flame safeguard device (min. 2Vdc for SLATE and
1.25Vdc for 7800-series). A cable that is chosen too long
weakens the flame signal and may cause nuisance flame
failures, resulting into a safety shutdown of the burner.
Using a shielded cable (only connect to ground on
controller side, i.e., terminal G) always helps to reduce
noise. Avoid running flame sensor cables in parallel
with "noisy" cables, like power supply cables or ignition
•
Two flame detectors can be wired in parallel to reduce
nuisance shutdowns in difficult flame sighting
applications.
•
A swivel mount is available to facilitate flame sighting
•
-40°C (-40°F) rated ultraviolet sensing tube is available.
•
Incorporates UV Sensor tube checking feature; used with
R7861 and SLATE Dynamic Self-Check amplifiers.
•
High pressure 50 psi (345 kPa) quartz viewing window,
magnifying lens and antivibration mount are available as
accessories.
•
Housing meets IP67 enclosure standards.
•
C7061F1003 only: explosion-proof housing, meets
EExd IIC T6 classification.
•
Protective heat block built into mounting flange.
