and operating this product according to the
instructions and warnings that follow. Failure
to do so could create danger to life and prop-
erty and result in voiding all warranties con-
nected with this product.
WARNING:
1. Conduits or wiring troughs from probes and
sensors to the controller must not contain
other foreign wires. No other wiring is per-
mitted with the probe wires and leak sen-
sors in the intrinsically safe area of the
system.
2. The conduit run from the probe to the con-
troller must not exceed 2,500 feet. See
Installation diagram X76D518.
3. All conduits must enter the controller
through the threaded hubs provided.
4. Do not install the controller in a volatile,
combustible, or explosive atmosphere.
5. The X76CTM System must be installed
in an environment that is within the operat-
ing specifications of the system.
NOTE: The controller must be located in a
general purpose environment with a mini-
mum temperature of 32°F. Check the sys-
tem specifications for further information or
call Ronan Engineering for assistance.
6. All external equipment used with the sys-
tem must comply with the National
Electrical Code for the area where the
equipment is being installed. This is particu-
larly important when selecting external
horns, push buttons and relays to be used
with the X76CTM System.
Failure to comply with these warnings
could result in serious injury, property loss
and equipment damage.
3.3 Intrinsic Safety Check for Warranty
Registration & Checkout
Refer to the installation drawings in the back of
this manual for details.
1. Check to be sure that probe wires are con-
tained in a separate, dedicated rigid con-
duit. The conduit and wiring troughs from
the probe or liquid sensors to the controller
must not contain any other wires.
2. Make sure the probe to controller wiring
does not exceed 2,500 feet. See the instal-
ation drawing for proper wiring require-
ments. All conduits must enter the controller
through the threaded hubs provided.
production quality equipment and inspection of
manufacturing and quality control facilities. Of
particular consideration are the adequacy of
design and workmanship, uniformity and
dependability of production, effectiveness of
quality control, functional suitability, assurance
of availability of service, and replacement of
parts.
Installation of intrinsically safe monitors makes
it mandatory to maintain complete isolation
between the field contact wiring and any other
potential source of voltage.
To be completely assured of an intrinsically
safe installation of the X76CTM, all equipment
used must be installed by a Ronan Authorized
Service Contractor. The installation, including
the wiring, plus all the contact inputs, must
meet requirements of isolation to avoid any fail-
ures that may occur in the system.
3.1.1 CAUTION
The X76CTM monitor enclosure must be
mounted in a general-purpose area as defined
by the National Electrical Code.
All wiring to sensors (i.e., Level Gauge Probes
95040XB, 95140XB; Level Sensors LS-1, LS-3,
LS-3s, LS-3ss, LS-7, LS-7s, LS-30, LS-100,
HVA; Pressure Switch JT-2P; and Vacuum
Switch JT-2V), must be installed in a separate,
dedicated conduit, to comply with intrinsically
safe requirements.
All wiring to auxiliary relays must be kept sep-
arate from the probe and sensor input wiring.
The X76CTM chassis must be properly
grounded including the intrinsically safe ground.
NOTE: Ronan Engineering Company does
not accept the responsibility for the installa-
tion of the intrinsically safe equipment.
3.2 General Safety
***Please read before beginning setup***
This product has been installed and will oper-
ate in a highly combustible environment of a
gasoline storage tank. It is essential that you
carefully read and follow the warnings and
instructions in this manual to protect yourself
and others from serious injury, explosion, or
electrical shock.
For safety reasons, we have taken particular
care in the design of this product to limit power
in the wiring to the fuel tanks and to keep that
wiring physically separated from other wiring.
It is your responsibility to maintain the effec-
tiveness of these safety features by starting up
