Georg Fischer Signet 2650 DryLoc User manual

The Signet 2650 Amperometric Electronics provide the polarization voltage and signal conditioning required
by all Signet Amperometric Sensors. Sophisticated circuitry makes system setup and verifi cation easy.
Features:
• Passes data stored in sensor memory, such as factory calibration data, service time, range and more.
• Signet's 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.

CAUTION!
• Remove power before wiring input or output connections.
• Follow instructions carefully to avoid personal injury or
damage to the electronics.
CHEMICAL COMPATIBILITY WARNING
The retaining nuts of the Amperometric 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 fl 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.
Insert sensor fully into fi tting.
Lubricate O-rings with a non-petroleum
based, viscous lubricant (grease)
compatible with the system.
1
Align the 2650 Electronics with the
pins on the sensor. Engage it by
gently turning the lock ring ¼-turn
counter-clockwise.
3
Install the yellow nut on to the fi tting
and hand tighten. Do Not Use Tools.
2
Do Not Use Lubricant or Sealing Tape on Threads.
Do Not Overtighten.
The bottom yellow nut is
not used when using the
2650 electronics with the
Signet 463X fl ow cell.

Chlorine Digital (S3L) Wiring
• Remove approximately 10 mm (0.4 in.) of insulation and tin each conductor before inserting into terminals.
• Refer to the wiring diagram above to connect the 2650 cable to the terminals on the 8630 Chlorine Transmitter.
• Maximum cable length is 30 m (100 ft).
• Cable should have noise immunity for the sensor signal of up to 30 m (100 ft).
• Cable capacitance must be less than 30 pF/foot.
