Innotech Genesis V4 System - Manual (Page 73)

Installation Instructions for Innotech Genesis Systems
Edition 011100 4-18
NOTE
The analogue output circuit resistance for the Genesis I and II Digital
Controllers and the GENII MPC should be at least 2,000 Ohms. The
circuit resistance for the GENII AO REM should be at least 5,000
Ohms.
g. Disconnect the meter and reconnect the signal wire disconnected in Step c.
h. Repeat Step c. through Step g. for the remaining analogue outputs.
i. Turn off any power applied in Step b.
4-1.3. INSTALL AISCs. Analogue Input Signal Conditioners (also referred to as Input
Straps in some other Innotech documents) are insert plugs used to configure the Genesis unit’s
input to match the analogue input device. All units having analogue inputs require an AISC
for each input channel; these units are:
Genesis II Digital Controller
Genesis I Digital Controller
GENII MPC Mid Points Controller
GENII AIM Analogue Input Module (LEM)
GENII AI REM Analogue Input Module
With all power off, and using the computer-generated wiring diagram (Figure 4-5) as a guide,
insert each AISC module into its assigned slot. The modules are keyed to prevent them from
being plugged-in backwards. When all AISCs are installed, double-check the installation.
The system will not operate correctly with an AISC plugged into the wrong slot.
4-1.4. SET JUMPER PLUGS. Various jumper plugs throughout the system must be
set properly before power can be applied to the system. The jumper plugs are of three
categories:
Address Plugs set the address of each Local or Remote Expansion Module.
Analogue Output plugs are used to select either Variable or Heat Valve Mode of operation
for analogue outputs. Refer to Paragraph 3-3.1.5 for a definition of Variable and Heat
Valve Modes.
End-of-Cable jumpers provide the proper termination impedance for the RS485 Comms
Cable. It is installed in the last unit of the cable run.
The computer-generated wiring diagram (Figure 4-5) shows the locations and required settings
for each address jumper and analogue output jumper.
Table 4-4 is provided as an aid for properly setting the various jumper plugs. The table lists
each Genesis unit requiring a jumper setting, the types of jumper plugs and the reference
paragraph containing instructions for setting them.
