CALogix Installation Instructions
System Overview
CALogix is a modular multi-loop PID controller with logic function capability. The controller consists of a
DIN-rail mount base-unit that incorporates power supply, RS485 communications ports and slots for up
to 4 control modules. The control modules are available as PID or Logic I/O and can be selected then
mounted into the base-unit as required for the application. Variations in PID control modules include
temperature sensor and linear (0-50mV, 4-20mA, 0-5V & 0-10V) inputs with options for relay, ssd or
analog (4-20mA, 0-5V & 0-10V) outputs. Logic I/O modules have user defined 0-5, 0-10, 0-24Vdc inputs
with relay or ssd outputs. All wiring connectors to the base unit and control modules are plug-in to
reduce installation and maintenance times.
CALogix is configured using the Windows based CALogix-sw configuration tool which is provided with
each base-unit. PID setup, input & output parameter settings, profile creation and writing logic function
block diagrams can all be performed within the software utility. These settings can be read, modified and
written to and from the controller and also saved on the PC as a file to be recalled at a later date when
required. The program also provides information on current process value, set-points and output status
which can be useful when commissioning the system.
Mechanical Installation
The controller is designed as two main components
BASE-UNIT
DIN rail mount device containing main CPU and connections for up to 4 control modules.
CONTROL MODULE
PID or Logic control modules can be mixed as required for the application and plugged in to base-unit.
1 base-unit and 1-4 control modules must be used for operation of product. A CALogix system can
DM0000M20
only be configured using CALogix-sw pc-based software.
MOUNTING
To mount a base unit with control modules proceed as follows:
1. Affix 35mm type DIN rail securely to mounting surface, minimum length 140mm. The unit
should be mounted vertically as shown.
2. Attach carrier unit to DIN rail ensuring the spring release is at the bottom, facing downward.
3. Ensuring the input terminals are facing downwards, add the control modules to base unit.
Press the top and bottom tabs on the module lightly and ensuring module is kept straight,
push to locate in base unit (see diagram below).
4. Pre-wire connectors and plug into the appropriate modules (we suggest wire markers for
identification)
REMOVING A MODULE
1. Isolate supply to CALogix and all module input and output connectors.
2. Unplug connectors to module requiring removal.
3. Press tabs as shown above to release module.
4. Carefully pull the module away from base-unit ensuring tabs are free to remove.
