consequences rising out of not following above precautions.
1. INTRODUCTION
MCB-200 is a multifunction digital timer with 1 CO contact. It offers wide time adjustment range
between 0.2-9999 seconds and 0.1-9999 minutes.
MCB-200 has 15 different functions with wide adjustable time ranges. The main application area is
the industrial and automation control systems. Wide supply voltage range and one output relay with
C/O contacts offer the highest flexibility for many applications.

1.2.3 Output
MCB-200 has one changeover relay output. According to VDE 0110 and IEC 60947-1 standards; switching
capacity of relay output is 8A, 2000VA, 250 V. and maximum electrical life time is 1x 10^6.
1. ONSrt : Indicates that the relay will start as closed.
2. OFFSrt: Indicates that the relay will start as open.
3. Srt-Input Icon: Indicates that the function is started with external input.
4. Indicates whether function trigger is Level or Edge.
5. Battery

7. Time setting indicator for Star-Delta function
9. Numeric Two Digits: Show function number.
10. Stop: Indicates that stop input is active. Start: Indicates that stop input is active.
11. When R1 or R2 relays are activated, the center of the circles are turned on. Rand Lletters are used
to indicate left or right direction when inverser relay function is selected. Star-Delta: Indicate the output
relay state in Star-Delta function.
12. Indicates the time type of functions.
13. In the main menu, it shows the elapsed time.
14. In the main menu, it shows the entered time. In the settings menu, it shows the function names.
1.2.2 Button functionality
SET, ESC, UP and DOWN buttons help to select functions and set their times.
UP button goes to previous menu item in Settings Menu and increase selected parameter value.
DOWN button goes to next menu item in Setting Menu and decrease selected parameter value.
SET button is for entering data. When pressed at least 3 seconds, Setting Menu is selected.
ESC button exits from a menu.

1.2.4 Inputs
1.2.4.1 Start Input and Stop Input:
These inputs are voltage-free dry inputs.
Start Input: For some of the functions, output depends on the state of the start input or input pulses
from start input. When user shorts two terminals of this input, start input activates.
Stop Input: When stop input applies, the timing pauses with stop input's leading edge. When stop
input is removed, the timing continues to count from it's last value with stop input's trailling edge.
Stop input affects all functions as the same without any exception. When user shorts two terminals
An Example: This function needs td delay time to release relay. When stop input is applied, it stops
counting and saves the time t1. With stop input's trailing edge, counting continues from the saved
time t1 until delay time td (Here td=t1 + t2). While stop input is active, the relay doesn't change its
position.

2. OPERATING INSTRUCTIONS
When the device is taken out of the box, an installation menu will be displayed. Language and function
settings are done in this menu as seen in the figure below. Afterwards, device returnss to main menu and
starts operating.
Stop : Stop Input
R : R1 Relay
td : Delay Time
t1 : Time elapsed until Stop Input is activated (t1<td)
t2 : Time elapsed after Stop Input is deactivated (td=t1+t2)

1. On Delay / Start by external trigger leading edge
This funcition is controlled by start input. Time counting starts with the leading edge of the start pulse;
at the end of time td the output relay is activated and remain activated while start input pulse is ON
Basic settings map is shown below. There are two main submenus as function selection and display
settings.
Function Selection Submenu: A new function is set from function selection menu. In this submenu,
user chooses a function, sets t parameter/parameters for selected function; assigns relay output.
Display Configurations Submenu: Changing password, adjusting contrast, activating backlight
or changing language is done from this submenu.

2. On Delay / Start by external edge re-trigger
This funcition is controlled by start input. Time counting starts with the leading edge of the start pulse;
at the end of time td the output relay is activated and remain activated until next start pulse is applied.
3. Off Delay / Start by external trigger trailing edge
This function is controlled by start input. Output Relay is activated when start pulse is applied and remain
on; time counting starts with the trailing edge and output relay is deactivated at the end of delay time td
lf trigger pulse occur during time counting period, elapsed time is reset.

4. Symmetric Flasher / Start by external trigger leading edge / Relay ON start
This function is controlled by start input. With the leading edge, output relay is activated and remain
on during ton. After that, it is deactivated and toff starts. This cycle is repeated while start
pulse is on (high).
5. Symmetric Flasher / Start by external trigger leading edge / Relay OFF start
Function is similar to the ON Start version (function 4) with the exception that the output relay start
as passive.

This function is controlled by start input. With the leading edge, output relay is activated and remain
on during ton. After that, it is deactivated and toff starts. This cycle is repeated until the next edge-
retrigger pulse. If a trigger pulse occur during ton, time counting is reset and ton time counting
is restarted.
