GF DryLoc 2650 User manual

GF 2650 DryLoc®Amperometric Electronics
English
The 2650 Amperometric Electronics provide the polarization voltage and signal
conditioning required by all GF Amperometric Sensors. Sophisticated circuitry
makes system setup and verication easy. The 2650 Amperometric Electronics
processes signals from a chlorine electrode and transmits digital data via a three
wire cable to the 9950-X Chlorine Controller. The DryLoc®electrode connector
quickly forms a robust assembly with the sensor. The Smart Sensor Electronics
also accesses stored factory and real time environmental data stored on the
chlorine sensor.
Features:
• Passes data stored in sensor memory, such as factory calibration data,
service time, range and more.
• GF patented DryLoc®connector provides quick assembly and a secure
connection.
Gold-plated contacts and an O-ring seal ensure a waterproof and reliable
interconnect to the sensor.
• Separate drive electronics from sensor make for easy sensor replacement
without running new cable.
• DryLoc®connectivity allows easy sensor removal for calibration.
* NOTE: The 9950-X Chlorine Controller is not compatible with the standard 9950 controller.

Refer to your local Georg Fischer Sales o󰀩ce for the most
current warranty statement.
All warranty and non-warranty repairs being returned must
include a fully completed Service Form and goods must be
returned to your local GF Sales o󰀩ce or distributor.
Product returned without a Service Form may not be
warranty replaced or repaired.
GF products with limited shelf-life (e.g. pH, ORP, chlorine
electrodes, calibration solutions; e.g. pH bu󰀨ers, or other
solutions) are warranted out of box but not warranted against
any damage, due to process or application failures (e.g. high
temperature, chemical poisoning, dry-out) or mishandling (e.g.
broken glass, damaged membrane, freezing and/or extreme
temperatures).

CHEMICAL COMPATIBILITY WARNING
The retaining nuts of Chlorine, pH and ORP electronics are not designed for prolonged contact with aggressive
substances. Strong acids, caustic substances and solvents or their vapor may lead to failure of the retaining
nut, ejection of the sensor and loss of the process uid with possibly serious consequences, such as damage to
equipment and serious personal injury. Retaining nuts that may have been in contact with such substances, e.g.
due to leakage or spilling, must be replaced.
Wiring
Wiring to the 9950-X Chlorine Controller
To replace the 2650 electronics in a 463X Chlorine panel:
• Measuring from the yellow housing threaded end, cut the cable to approximately 838 mm (33 in.).
• Remove approximately 10 mm (0.4 in.) of insulation and tin each conductor before inserting into terminals.
• For calibration and conguration please refer to the 463X Chlorine Analyzer System and
9950-X Chlorine Controller manuals.
