Safety Instructions - GPI SC510 Guía De Operación

An electronic circuit, including GPI Scaled Pulse Mod-
ules, perform this conversion by counting and accumu-
lating input pulses until the count reaches the known
K-factor. It then generates an output pulse. At that time
the counter/accumulator "starts over" with a new count,
and this process repeats continuously as long as input
pulses are present.
The GPI Scaled Pulse Module presents a series of
10-position switches by which the user can set the
desired K-factor.
All user connections to the GPI Scaled Pulse Module
are made through rugged, convenient screw-terminal
blocks, so that in typical setups no soldering, "wire nuts"
or electrical tape is required.
CAUTION
This unit is not FM Approved. Therefore, use of
this transmitter with an approved metering system
voids FM Approval.
NOTE: This unit is DC powered, requiring an input power
supply of 5 to 30 volts.

SAFETY INSTRUCTIONS

• When measuring flammable liquids, observe precau-
tions against fire or explosion.
• When working in hazardous environments, always
exercise appropriate safety precautions.
• When applying external power to the transmitter, use
DC power only.
• Disconnect external power to the transmitter before
detaching or attaching input or output wires.
• Ground loops between sensor and user equipment
can damage the module and can be dangerous.
• Be sure O-rings and seals are kept in good repair.
INSTALLATION
CAUTION
Installation should be performed only by qualified
personnel, and in accordance with local governing
regulations.
The following installation guidelines are separated by
meter series and mounting type.
Precision G Series or IM Series:
• Local – The SC510 Scaled Pulse Module mounts
directly to the 1-inch MNPT conduit connector or
Reducer Bushing. (IM Series)
• Remote – The SC500 Scaled Pulse Module con-
nects via an output cable as shown in the Wiring
Diagram.
2
Industrial Grade G2 Series:
• Local – The SC510 Scaled Pulse Module requires
the GPI 510 Conversion Kit (Part #11344001) for
local mounting to the G2 Series meter.
• Remote – The SC500 Scaled Pulse Module con-
nects via an output cable as shown in the Wiring
Diagram.
GM Oval Gear Series:
• Remote – The SC500 Scaled Pulse Module con-
nects via an output cable as shown in the Wiring
Diagram.
Mount the GPI Scaled Pulse Module using bolts, screws
or standard U-bolts for pipes. Mounting options include:
• Wall
• Pipe
• Meter (1- inch FNPT conduit connection required)
Environmental
Choose a mounting location suitable for the Scaled
Pulse Module. The ideal mounting location is where the:
• flowmeter is as close as possible.
• mounting surface has minimal vibration.
• ambient temperature is -40° F to +185° F (-40° C to
+85° C).
• cable lengths are minimal.
Avoid mounting locations where the Scaled Pulse
Module is:
• subject to constant exposure to water or other liquids
(occasional low-pressure splashing will not harm unit
if cable entry points are well-sealed).
• close to high voltage/current runs, DC motors, inter-
nal combustion engines or frequency inverters.
Cable Guidelines
The open collector signal itself is very resistant to electri-
cal noise pickup and shielded cable is seldom needed
except in very "noisy" (electrical) locations and/or when
very long runs (thousands of feet) are used.
Sensor Cabling
• Some products come with 20 ft. of shielded cable.
• If you require a longer cable, a 100 ft. cable kit is
available from GPI, or use Belden 9363 cable. When
wiring longer lengths of cable, be sure to connect
the shield to Module COM ONLY! (Multiple shield
connections may cause ground-loop problems).
• Some trial and error may be needed because of the
wide variety of user conditions. Try to keep cable
lengths short!
