Sub-Zero PCG100 Series Instruction Manual

PCG100 Series
Instruction Manual
Introduction
Subzero PCG is the programmable controller designed to be used for general
application. It consists of input block to take input from probes, transducers,
humidifier etc. and able to control various devices like compressor, control
valves, heater etc. indicator to cover any type of application in the air-
conditioning sector, cooling sector and any relative area. As the system is
one of the most technologically advanced, it is flexible and can be
customized for it to be adapted to the user's particular requirements.
Caution for your Safety
ELECTRIC SHOCK: Please do not touch the relay terminal (live parts) or
socket terminal (live parts) while the power is on. This may lead to electric
shock.
WIRING: The probe and its corresponding wires should never be installed in
a conduit next to control or power supply lines. The electrical wiring should
be done as shown in the diagram. The power supply circuit should be
connected to a protection switch. The terminals admit wires of upto 2.5sq
mm.
WARNING: Improper wiring may cause irreparable damage and personal
injury. Kindly ensure that wiring is done by qualified personnel only.
MAINTENANCE: Cleaning: Clean the surface of the controller with a soft
moist cloth. Do not use abrasive detergents, petrol, alcohol or solvents.
Controller: Controller should be installed in a place protected by vibration,
water and corrosive gasses and where ambient temperature does not
exceed the values specified in the technical data.
Probe: To give a correct reading, the probe must be installed in a place
protected from thermal influences, which may affect the temperature to be
controlled.

4. Programming Environment
All Subzero PLC use the following software as a processing environment:
• SZ Logic – Customized Programming Software which comes
complementary. It uses popular Ladder Logic Diagrams and "C"
Language.
• Key Feature of SZ Logic – subzero make NTC sensor (10k @ 25deg C)
is readily integrated.
• Online DEBUG allows user to block and force the value of the
variables to speed up the testing and ease fault findings.
5. Onsite Programming
Following is the procedures for onsite USB Programming:
• Compile project in SZ Logic.
• A file with "projectname.szd" will be created in the project folder.
• Rename above file as "PLCPRG.szd" only.
• Insert a pendrive. Format the pendrive as FAT32.
• Copy the "PLCPRG.szd" file to Pendrive. Do not keep in any folder.
Remove pendrive from PC.
• Power off the PLC and insert the pendrive in the PLC.
• Power on the PLC. Upon successful downloading of the program, the
RUN LED on PLC will blink 6 times and then will remain ON.
• If RUN led doesn't blink, repeat previous 2 steps.
• When done, power off the PLC and remove the pendrive.
