Power Connections; Transducer Connections; Input/Output Connections - GE TransPort PT878 User Manual

2.1.1 Power Connections

The PT878 is powered by either a 100-120/200-260 VAC wall mount
plug-in module, or by 5 internal C
batteries or by a pack of 3.0 Ahr NiMH batteries. (An optional power
supplement, part #703-1283, uses 6 AA alkaline batteries.) When you
receive the PT878, the batteries are not charged; therefore, to make remote
measurements using the batteries, follow the instructions on page 9 to
charge the batteries. In either case, you must connect the power cord to the
appropriate terminal as shown in Figure 2 on page 6.
To ensure the safe operation of the PT878, you must
WARNING!
install and operate it as described in this manual. In
addition, be sure to follow all applicable safety codes and
regulations for installing electrical equipment in your
area. The PT878 and its transducers are designed for use
only in general-purpose locations.

2.1.2 Transducer Connections

The transducer cables connect to the PT878 with LEMO
connectors. Each color-coded cable should have a collar labeled
UPSTREAM or DOWNSTREAM. Make transducer cable connections to
the top of the flowmeter as shown in Figure 2 on page 6. Because there are
various types of transducers and installations, transducer installation is
discussed separately in the Liquid Transducer Installation Guide (916-055).

2.1.3 Input/Output Connections

The PT878 provides one 0/4-20 mA current output and two 4 to 20-mA
analog inputs with switchable 16-V supply for loop- powered temperature
transmitters. It also supports digital, frequency, and totalizer outputs.
Connect the inputs/outputs using a LEMO
Figure 2 on page 6. The pin numbers for the connector and the color code
for the standard input/output cable are shown in Table 1 on page 8.
