2SERIES 900 SMART PROGRAMMABLE RELAYS
INTRODUCTION
Providing excellent performance and functionality, the Series 900 relay performs simple logic, timing, counting, and real time clock operations. It is
an ideal programmable controller designed for use in small commercial and industrial automation sectors, including packaging machines, printing
machines, commercial building controls, parking controls, lighting applications, and more, where cost is a primary design issue. All programming and
data adjustments can be done via the on-board keypad and display or with the help of the software.
Programming the Series 900 relay with the SPR-soft III software is quite simple, even without particular programming knowledge. It facilitates
program generation, project simulation, and documentation which are accomplished simply by using the pick and place functionality, allowing
maximum ease of operation.

KNOWING THE PRODUCT
THE C3CONTROLS SERIES 900 SMART PROGRAMMABLE RELAY PROVIDES THE RIGHT SOLUTION FOR ALL YOUR CONTROL NEEDS!
DEL
This key is used to delete a program element or a blank line, if the cursor is
located at the extreme column.
ALT
This key is used for selecting/exiting a parameter in the edit mode and to
show either the parameters or program while the program is running. This
feature is also useful for debugging.
OK
This key is used to insert a program line, when the cursor is blinking in
the rst column of the rst row. During the parameter entry while editing
this key saves the changes and proceeds to next parameter. In RUN mode,
this key can be used to select one of the three displays. This also selects/
deselects links.
ESC
This key is used to exit the menu or a selection. During the parameter
entry it proceeds to the next parameter without saving the changes.
ARROW
On the program editor screen, the arrow keys are used to move up, left,
down and right. The position on screen is shown by a cursor or blinking
text.
AUXILIARY or Z-KEYS
Arrow keys are called auxiliary keys in RUN mode. They are used as push
buttons to get signals from the user. If the user goes in PAR (parameter)
mode, then these keys are not available as Z-keys. At that time these keys
are used as arrow keys.
FRONT VIEW OF KEYPAD & FUNCTIONS OF KEYS
The 8 keys located on the front facia of the Series 900 relay are used to congure, program, and control the application. They perform the following actions:

WIRING DIAGRAMS
POWER SUPPLY WIRING
1. Although the Series 900 relay has been designed to withstand the
negative eects of any electrical noise that might be present in the
incoming power supply it may be necessary to insert an isolation
transformer between the supply and the line terminals of the Series
900 relay.
2. While using the DC Series 900 relay, run the 24V DC input line away
from any AC supply lines.
WIRING OF INPUT/OUTPUT
1. Separate the input and output lines.
2. When the output lines are positioned close to power supply lines or the
input lines shielding and separate grounding may be required.

PROGRAMMING AT THE DEVICE: MENU & FUNCTIONS
Programming and other settings in the Series 900 relay can be done using the
software as well as on the device itself with the help of the backlit display and keypad.
When the connections are made and the device is powered ON, screen 1 is displayed
on the device. By default the cursor will blink on the‘PROGRAM’ option. Using the Up/
Down keys, user can select between any of the options.
When the cursor is on the PROGRAM option and OK key is pressed, then screen 2 is displayed.
When screen 2 is being displayed, the cursor is on the ‘EDIT’ option.
Press the OK key to enter this option and screen 6 will be displayed. Similarly
by pressing the Down key and OK, one can enter the other functions: “DELETE”,
“TRANSFER”, “MODBUS CONF”, and screens 7, 8, and 9 will be displayed respectively.
EDIT
This function allows the user to enter a new program or edit an existing program. If
password is set, then this function is accessible only with the correct password.
DELETE
This function will clear the entire program stored in the Series 900 relay. If password is
set, then this function will work only with correct password.
TRANSFER
This function will transfer the program from device to memory card or vice versa.
Program data on memory can also be deleted in this mode.
MODBUS CONF
This function will set Modbus Slave conguration data.
The user can set the following communication parameters:
• SLAVE ID, BAUD RATE, PARITY, STOP BIT
When screen 1 is being displayed, press the Down key to shift the cursor to the RUN
option and press the OK key to enter it. Screen 3 will be displayed.
RESET
The RESET mode resets all the previous states of inputs/outputs, clears timer and
counter states, and starts afresh.
CONTINUE
The CONTINUE mode does not change the states of the inputs/outputs and special
functions and continues with the execution of the program.
When the cursor is on the PARAMETERS option and OK is pressed then screen 4 will be
displayed.
PARAMETERS
This function displays and allows the user to change parameters of special functions
like timer, counter, time switch (clock), compare counters and analog functions used in
the program. This may be password protected and may have additional individual lock
for each parameter.
When the cursor is on the UTILITIES option and OK key is pressed, then screen 5 is
displayed.
When screen 5 is being displayed, the cursor is on the ‘SET CLOCK’option.
Press the OK key to enter this option and screen 10 will be displayed. Similarly by
pressing the Down key and OK, one can enter the other functions: “PASSWORD”, “EXT
MOD”,“BACKLIT CONF”, and screens 11, 12, and 13 will be displayed respectively.
SET CLOCK
This function is used to set the day and time: Day of the week, Date, Hours-Minutes.
This function is available only on the Series 900 relay unit.
PASSWORD
This function allows setting of password. If password is set, certain functions like
Program and Parameters are protected and are accessible only when correct password
is entered. The Password can be set or removed; the status is indicated by the open or
closed lock symbol.
EXPANSION MODULE (EXT MOD)
This function allows the selection of the Expansion Modules (A/B/C). Maximum of three (3)
Expansion Modules can be connected to the Series 900 relay main unit. In the SPR-soft III
on PC, expansion modules have to be chosen using the “Conguration”menu.
BACKLIT CONF
This function allows the setting of backlight in either ON, OFF, or AUTO mode. In the
AUTO mode, the backlight comes up only when a key is pressed on the device and
remains for 10 seconds. If the ON or OFF modes are selected the backlight will be
permanently ON or OFF respectively.

TRANSFER
The TRANSFER function allows data to be transferred from Memory Card to the
Series 900 relay or vice-versa.
Transferring data to the memory card is useful when the user wants to load the
same program in many Series 900 relay units. In this case, instead of using PC,
user can make use of memory card, which is capable of storing one program. This
feature is particularly useful on the production line where user is not required to
edit and debug the program and a PC is not available. In this mode of transfer
”PASSWORD” and ”UTILITIES” such as Backlit Conguration and Expansion
(Extension) module state will also get transferred with the program.
