GF 4630 User manual

The Signet Chlorine Analyzer System is an integrated, all-in-one chlorine panel system designed to measure free chlorine in
drinking water and clean fresh water treatment applications.
Features:
Complete chlorine analyzer system allows quick setup and easy•
installation. Connect to a water source and plug it in.
Unique integrated clear flow cell combines sensors, flow regulator,•
filter and rotameter in one compact unit.
Built-in rotameter facilitates flow rate confirmation at a glance.•
Integrated flow regulator with removable filter accepts inlet pressures•
of 15 to 150 psi while maintaining constant flow and minimal pressure
to the sensors.
Water flows vertically into sensor tip, eliminating bubble entrapment.•
Raised exit in flow cell sensor chamber ensures sensors stay
submerged even when system and flow is turned off.
System is supplied with pre-wired electronics, power cable, 4 to 20 mA•
current loop and relay output capability.
Flow cell accommodates two sensors; one chlorine and an optional•
pH sensor.
Automatic pH and temperature compensation or manual pH value•
input capability for chlorine reading accuracy.
Easy viewing of the transmitter via the bright backlit LCD display.•
Moisture proof NEMA 4X wiring enclosure.•
Exterior panel enclosure available for outdoor mounting applications.•

4. Mounting
Mount the panel according to electrical, building, and or plumbing codes and•
seismic requirements.
The panel must be mounted vertically in an upright position.•
Use four 6 mm (¼ in.) diameter screws or bolts of sufficient length to mount•
the panel to a sturdy vertical surface. A mounting template is provided.
Allow clearance on the sides and bottom for service to the unit.•
Mount in a shaded location out of direct sunlight. Indoors is recommended.•
Bright light can promote algae growth.
Keep panel system electronics and enclosure away from dripping water.•
If the system is mounted outdoors, an outdoor enclosure for the whole•
system must be used to protect the electronics and flow cell from light,
rodents, insects and dirt. A suitable outdoor box is available from Georg
Fischer Signet.
5. Tubing Connections
Use suitable tubing that is rated for your inlet pressure. Use hose clamps.•
NO
Valve position for start up and normal use
Note: Turn off inlet valve first when stopping
water flow.
• The drain tube must be positioned lower than
the influent water source to allow proper flow
through the flow cell. The flow cell must drain by
gravity, not system pressure.
Inlet Quick Release Connection
Press down gray plunger to release. Water flow
is automatically shut off when disconnected.

54630 Chlorine Analyzer System
Step 1. Mount the panel on a vertical flat surface using appropriate hardware.
Step 2. Install the influent water source to the "Inlet Port" nipple assembly of the flow cell. Use tubing
that is properly rated for the system pressure and secure with hose clamps.
Step 3. Install tubing on the "Drain" port and direct the tube to a proper drain.
Step 4. Open the wiring enclosure and wire any 4 to 20 mA and relay outputs. (See section 7: Wiring)
Step 5. Remove sensor access plugs from the flow cell. If the optional pH sensor is NOT used, only remove the
right plug from the flow cell.
Step 6. Remove the protective cap from the chlorine electrode tip and install the electrode into the flow cell.
(Keep the electrode tip cap in a safe place for future use. It is recommend to use the cap to protect the
sensor during the removal of the electrode for cleaning or maintenance of the flow cell.)
Step 7. Repeat step 6 if the optional pH sensor is being used.
Step 8. Verify the inlet and drain ball valves are in the open position and the sample port is in the off position.
(See section 5: Tubing Connections)
Step 9. Turn on the influent water source and check the system for leaks.
Step 10. Plug in or apply input power to the system.
NOTE: A new chlorine sensor requires a 4 hour conditioning period with power on and water flowing past the
sensor prior to calibration. All new chlorine and pH sensors require calibration during the start up of a system
and also throughout the life of the sensor. See the 3-8630-3P transmitter manual for the proper calibration
procedure.

7. Wiring
Follow all local and government recommendations and methods
for installation of electrical connections to and between the
system and other devices.
System Input Power
The panel system is pre-wired with an auto switching power•
supply that is rated for 100 to 240 VAC 50/60 Hz input.
The supplied plug is a standard North American Type B. If•
the source is 220 to 240 VAC, use an adapter plug.
Install in a properly grounded circuit.•
Install a circuit breaker in the AC line for easy maintenance•
and short circuit protection.
If wiring via conduit connection, include a disconnect device•
(switch) to power down the system.
Output Connections
Use the wiring enclosure terminal block for output wire•
connections. Do not wire directly to the transmitter.
• Do not run 4 to 20 mA loop cables in the same conduit as the
power or other high voltage wiring.
Remove one installed jumper wire (from both of its terminals)•
on the terminal block in the enclosure for each loop device
connected. Replace the jumper if you later remove your loop
device. If only one loop device is connected, remove just one
jumper wire from its two terminals.
The panel system uses an active loop output wired to the•
enclosure terminal block.
If connecting to a PLC, use the PLC's passive input.•
The transmitter must have a jumper wire or loop device•
always connected to Loop 1.
Use Loop 2 when using only one loop output.•
WARNING
This panel system is wired for AC voltages that can injure
or kill. Wiring should be done by qualified personnel only.
Disconnect AC power before opening wiring enclosure.

12 to 24 VDC Input Wiring Conversion
If the power source supplied to the system will be 12 to 24•
VDC instead of 100 to 240 VAC, remove the AC wires from
the system. Disconnect the red and black output wires from
the power supply and connect your DC power source to
them.
If the AC wires are removed from the system, the earth•
ground connection on the green terminal block will be lost as
well. Run a separate ground wire into the wiring enclosure if
grounding is needed for the loop shield wire.

Sensor Removal
Caution
Over time, a sensor can get tight in the flow cell fitting. When
removing the sensor, avoid hitting the sensor electronics into the
bottom of the wiring enclosure if the sensor suddenly releases.
While holding the flow cell, grasp the yellow electronics as a
whole unit and carefully pull upwards, gently rocking back and
forth if necessary. Once the sensor is loose, disengage the
electronics, then remove the sensor.
TIP: A tool can be used to carefully pry the sensor electronics up
and out if it is difficult to remove.
Take care not to damage the components.
Flow Rate
The flow rate is in the proper range when the center line on the
float is within the Min. and Max. markers on the flow cell. The flow
range limits are 30.24 to 45.36 L/h (8 to 12 gal/h).

10. Cleaning
Under certain conditions, a dirty flow cell and filter can create a
chlorine demand which could lower the chlorine concentration in
the water flowing past the chlorine sensor. Because of this, it is
recommended to clean the filter and flow cell on a regular basis.
The frequency of necessary cleaning will depend on the application
in which the system is being used and the level of accuracy required.
Step 1. Keep the system powered on.
Step 2. Disable the relays and any output loops.
Step 3. Turn off the water flow.
Step 4. Remove the sensors and reattach their electronics
after removal.
Step 5. Install the vinyl caps on to the sensor tips or place
the tips of the removed sensors in a cup of sample
water for temporary storage while cleaning the flow cell.
Keep the sensor tips wet and the sensors energized.
Step 6. Remove the flow cell from the panel by removing the
knurled nuts. (Figure 1)
Step 7. Remove the remaining hardware from the flow cell.
(Figure 2)
Wash the surfaces with water or soapy water only.•
Use gentle, liquid dishwashing soap if necessary.•
Do not use commercial glass cleaning fluids.•
Use a soft, lint-free cloth.•
If your inlet pressure is less than 1 bar
(15 psi), remove the flow regulator.
WARNING: Do not disassemble the flow
regulator. There are no user serviceable
parts inside.
Remove filter screen to clean. If the filter
is not desired, it may be removed from the
system.
Flow Regulator
Service the flow cell on a clean, dirt free surface to avoid
scratches or damage to the flow cell.
