4-1.2.4. Checking Analogue Input Wiring. The analogue input wiring for the
following Genesis units should be checked as part of the commissioning process:
Genesis II Digital Controller
Genesis I Digital Controller
GENII MPC Multi Points Controller
GENII AIM LEM
GENII AI REM
Checking analogue input wiring requires special consideration due to the wide variety of
analogue input devices that may be used in the system. Some input devices function as
signal voltage sources; some devices function in the loop current mode and others provide
resistive inputs to the Genesis unit. For this reason there is no single procedure that can be
used on all analogue inputs.
Procedures presented in this manual are based on identifying the type of Analogue Input
Signal Conditioner (AISC) assigned to each analogue input channel. Since each analogue
input device requires a specific AISC type to match the signal to the Genesis unit, the type
of AISC assigned to an analogue input channel indicates the type of input signal and the
range. The various types of AISCs are listed in Table 4-3 along with the type of analogue
signal and the range. Reference to the paragraph containing the instructions for checking
the input wiring is also provided in Table 4-3. For example, an analogue input channel that
has Model TH2 AISC assigned receives its input from a thermistor device; the input circuit
is checked by measuring its resistance, which should be between 0 and 2k . Procedures
for checking the resistance are contained in Paragraph 4-1.2.4.3.
The type of AISC for each analogue input channel is determined when the system
configuration is established by the Genesis Configuration Software prior to delivery. The
configuration software automatically generates a Materials List and a Wiring Diagram,
which are delivered with the system. The Materials List shows the number of AISCs by
type but does not show which analogue input channels they are assigned to. The Wiring
Diagram (Figure 4-5) identifies the AISC type for each analogue input channel.
