Starter Management Module (SMM) (Fig. 52)
INPUTS — Inputs on strips J2 and J3 are a mix of analog
and discrete (on/off) inputs. Application of the machine de-
termines which terminals are used. Always refer to the in-
dividual unit wiring diagram for terminal numbers.
OUTPUTS — Outputs are 24 vdc and wired to strip J1. There
are 2 terminals used per output.
Options Modules (8-Input) —
The options modules
are optional additions to the PIC, and are used to add tem-
perature reset inputs, spare sensor inputs, and demand limit
inputs. Each option module contains 8 inputs, each input meant
for a specific duty. See the wiring diagram for exact module
wire terminations. Inputs for each of the options modules
available include the following:
OPTIONS MODULE 1
4 to 20 mA Auto. Demand Reset
4 to 20 mA Auto. Chilled Water Reset
Common Chilled Water Supply Temperature
Common Chilled Water Return Temperature
Remote Temperature Reset Sensor
Spare Temperature 1
Spare Temperature 2
Spare Temperature 3
OPTIONS MODULE 2
4 to 20 mA Spare 1
4 to 20 mA Spare 2
Spare Temperature 4
Spare Temperature 5
Spare Temperature 6
Spare Temperature 7
Spare Temperature 8
Spare Temperature 9
Terminal block connections are provided on the options
modules. All sensor inputs are field wired and installed.
Options module 1 can be factory or field-installed. Options
module 2 is shipped separately and must be field installed.
For installation, refer to the unit or field wiring diagrams. Be
sure to address the module for the proper module number
(Fig. 53) and to configure the chiller for each feature being
used.
Replacing Defective Processor Modules —
The
replacement part number is printed in a small label on front
of the PSIO module. The model and serial numbers are printed
on the unit nameplate. The proper software is factory-
installed by Carrier in the replacement module. When or-
dering a replacement processor module (PSIO), specify
complete replacement part number, full unit model number,
and serial number. This new unit requires reconfiguration to
the original machine data by the installer. Follow the pro-
cedures described in the Set Up Machine Control Configu-
ration section on page 55.
NOTE: Address switches on this module can be at any position. Ad-
dresses are only changed through the LID screen or CCN.
