GE XAMP-1-1-2-0-0 XAMP Preamplifer

The XAMP preamplifier is approved for use with

all wetted T5. and T17 transducers, to be used in

conjunction with the XGF868i or the GF868. A complete

potted assembly, the XAMP is a great improvement

in overall system reliability, simplicity and cost as

compared to previous preamplifiers.

The XAMP is mounted directly on the end of the

transducer. All cable connections are made in the

junction box. These is no need for an external junction

box and cable.

The XAMP package must be ordered as a separate line

item, similar to the PRE868. The T5 or T17 transducer

should be ordered without any junction box enclosure.

Specify option G=00 for either T5 or T17 (see below). All

XAMP enclosure options, as configured today, accept a

¾” NPT cable gland as standard. CSA certification is in

process and in place by the end of May 2013. This will

not affect ordering but may affect lead‐time.

The XAMP enclosure certifications are only valid when configured

with T5 or T17. Do not pair with any other transducer, as

certifications will not be valid.

The CBS 212A then provides full current boost to the generator exciter until

the voltage returns to a level just above the operating point setting.

The Controls and Indicators and Installation chapters provide information

about setting the Operating Point Adjustment.

An adjustable voltage limiting circuit prevents the Current Boost Module

output from exceeding the specified percentage of the nominal output

voltage (60. 120. or 220 Vdc). The Output Limit Select Jumpers are used

to select the nominal output voltage (60. 120. or 220 Vdc) and the Output

Limit Adjustment is used to set the desired percentage of the nominal output

voltage. The Output Limit Adjustment is adjustable over a range of 50 to

100 percent of the jumper-selected nominal output voltage.
