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.
